+PCRE LICENCE
+------------
+
+PCRE is a library of functions to support regular expressions whose syntax
+and semantics are as close as possible to those of the Perl 5 language.

+ChangeLog for PCRE
+------------------
+
+Version 3.0 02-Jan-02
+---------------------
+
+1. A bit of extraneous text had somehow crept into the pcregrep documentation.
+
+2. If --disable-static was given, the building process failed when trying to
+build pcretest and pcregrep. (For some reason it was using libtool to compile
+them, which is not right, as they aren't part of the library.)
+
+
+Version 3.8 18-Dec-01
+---------------------
+
+1. The experimental UTF-8 code was completely screwed up. It was packing the
+bytes in the wrong order. How dumb can you get?
+
+
+Version 3.7 29-Oct-01
+---------------------
+
+1. In updating pcretest to check change 1 of version 3.6, I screwed up.
+This caused pcretest, when used on the test data, to segfault. Unfortunately,
+this didn't happen under Solaris 8, where I normally test things.
+
+2. The Makefile had to be changed to make it work on BSD systems, where 'make'
+doesn't seem to recognize that ./xxx and xxx are the same file. (This entry
+isn't in ChangeLog distributed with 3.7 because I forgot when I hastily made
+this fix an hour or so after the initial 3.7 release.)
+
+
+Version 3.6 23-Oct-01
+---------------------
+
+1. Crashed with /(sens|respons)e and \1ibility/ and "sense and sensibility" if
+offsets passed as NULL with zero offset count.
+
+2. The config.guess and config.sub files had not been updated when I moved to
+the latest autoconf.
+
+
+Version 3.5 15-Aug-01
+---------------------
+
+1. Added some missing #if !defined NOPOSIX conditionals in pcretest.c that
+had been forgotten.
+
+2. By using declared but undefined structures, we can avoid using "void"
+definitions in pcre.h while keeping the internal definitions of the structures
+private.
+
+3. The distribution is now built using autoconf 2.50 and libtool 1.4. From a
+user point of view, this means that both static and shared libraries are built
+by default, but this can be individually controlled. More of the work of
+handling this static/shared cases is now inside libtool instead of PCRE's make
+file.
+
+4. The pcretest utility is now installed along with pcregrep because it is
+useful for users (to test regexs) and by doing this, it automatically gets
+relinked by libtool. The documentation has been turned into a man page, so
+there are now .1, .txt, and .html versions in /doc.
+
+5. Upgrades to pcregrep:
+ (i) Added long-form option names like gnu grep.
+ (ii) Added --help to list all options with an explanatory phrase.
+ (iii) Added -r, --recursive to recurse into sub-directories.
+ (iv) Added -f, --file to read patterns from a file.
+
+6. pcre_exec() was referring to its "code" argument before testing that
+argument for NULL (and giving an error if it was NULL).
+
+7. Upgraded Makefile.in to allow for compiling in a different directory from
+the source directory.
+
+8. Tiny buglet in pcretest: when pcre_fullinfo() was called to retrieve the
+options bits, the pointer it was passed was to an int instead of to an unsigned
+long int. This mattered only on 64-bit systems.
+
+9. Fixed typo (3.4/1) in pcre.h again. Sigh. I had changed pcre.h (which is
+generated) instead of pcre.in, which it its source. Also made the same change
+in several of the .c files.
+
+10. A new release of gcc defines printf() as a macro, which broke pcretest
+because it had an ifdef in the middle of a string argument for printf(). Fixed
+by using separate calls to printf().
+
+11. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure
+script, to force use of CR or LF instead of \n in the source. On non-Unix
+systems, the value can be set in config.h.
+
+12. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an
+absolute limit. Changed the text of the error message to make this clear, and
+likewise updated the man page.
+
+13. The limit of 99 on the number of capturing subpatterns has been removed.
+The new limit is 65535, which I hope will not be a "real" limit.
+
+
+Version 3.4 22-Aug-00
+---------------------
+
+1. Fixed typo in pcre.h: unsigned const char * changed to const unsigned char *.
+
+2. Diagnose condition (?(0) as an error instead of crashing on matching.

+
+Version 3.3 01-Aug-00
+---------------------
+
+1. If an octal character was given, but the value was greater than \377, it
+was not getting masked to the least significant bits, as documented. This could
+lead to crashes in some systems.
+
+2. Perl 5.6 (if not earlier versions) accepts classes like [a-\d] and treats
+the hyphen as a literal. PCRE used to give an error; it now behaves like Perl.
+
+3. Added the functions pcre_free_substring() and pcre_free_substring_list().
+These just pass their arguments on to (pcre_free)(), but they are provided
+because some uses of PCRE bind it to non-C systems that can call its functions,
+but cannot call free() or pcre_free() directly.
+
+4. Add "make test" as a synonym for "make check". Corrected some comments in
+the Makefile.
+
+5. Add $(DESTDIR)/ in front of all the paths in the "install" target in the
+Makefile.
+
+6. Changed the name of pgrep to pcregrep, because Solaris has introduced a
+command called pgrep for grepping around the active processes.
+
+7. Added the beginnings of support for UTF-8 character strings.
+
+8. Arranged for the Makefile to pass over the settings of CC, CFLAGS, and
+RANLIB to ./ltconfig so that they are used by libtool. I think these are all
+the relevant ones. (AR is not passed because ./ltconfig does its own figuring
+out for the ar command.)
+
+
+Version 3.2 12-May-00
+---------------------
+
+This is purely a bug fixing release.
+
+1. If the pattern /((Z)+|A)*/ was matched agained ZABCDEFG it matched Z instead
+of ZA. This was just one example of several cases that could provoke this bug,
+which was introduced by change 9 of version 2.00. The code for breaking
+infinite loops after an iteration that matches an empty string was't working
+correctly.
+
+2. The pcretest program was not imitating Perl correctly for the pattern /a*/g
+when matched against abbab (for example). After matching an empty string, it
+wasn't forcing anchoring when setting PCRE_NOTEMPTY for the next attempt; this
+caused it to match further down the string than it should.
+
+3. The code contained an inclusion of sys/types.h. It isn't clear why this
+was there because it doesn't seem to be needed, and it causes trouble on some
+systems, as it is not a Standard C header. It has been removed.
+
+4. Made 4 silly changes to the source to avoid stupid compiler warnings that
+were reported on the Macintosh. The changes were from
+
+ while ((c = *(++ptr)) != 0 && c != '\n');
+to
+ while ((c = *(++ptr)) != 0 && c != '\n') ;
+
+Totally extraordinary, but if that's what it takes...
+
+5. PCRE is being used in one environment where neither memmove() nor bcopy() is
+available. Added HAVE_BCOPY and an autoconf test for it; if neither
+HAVE_MEMMOVE nor HAVE_BCOPY is set, use a built-in emulation function which
+assumes the way PCRE uses memmove() (always moving upwards).
+
+6. PCRE is being used in one environment where strchr() is not available. There
+was only one use in pcre.c, and writing it out to avoid strchr() probably gives
+faster code anyway.
+
+

+
+
+Version 3.1 09-Feb-00
+---------------------
+
+The only change in this release is the fixing of some bugs in Makefile.in for
+the "install" target:
+
+(1) It was failing to install pcreposix.h.
+
+(2) It was overwriting the pcre.3 man page with the pcreposix.3 man page.
+
+
+Version 3.0 01-Feb-00
+---------------------
+
+1. Add support for the /+ modifier to perltest (to output $` like it does in
+pcretest).
+
+2. Add support for the /g modifier to perltest.
+
+3. Fix pcretest so that it behaves even more like Perl for /g when the pattern
+matches null strings.
+
+4. Fix perltest so that it doesn't do unwanted things when fed an empty
+pattern. Perl treats empty patterns specially - it reuses the most recent
+pattern, which is not what we want. Replace // by /(?#)/ in order to avoid this
+effect.
+
+5. The POSIX interface was broken in that it was just handing over the POSIX
+captured string vector to pcre_exec(), but (since release 2.00) PCRE has
+required a bigger vector, with some working space on the end. This means that
+the POSIX wrapper now has to get and free some memory, and copy the results.
+
+6. Added some simple autoconf support, placing the test data and the
+documentation in separate directories, re-organizing some of the
+information files, and making it build pcre-config (a GNU standard). Also added
+libtool support for building PCRE as a shared library, which is now the
+default.
+
+7. Got rid of the leading zero in the definition of PCRE_MINOR because 08 and
+09 are not valid octal constants. Single digits will be used for minor values
+less than 10.
+
+8. Defined REG_EXTENDED and REG_NOSUB as zero in the POSIX header, so that
+existing programs that set these in the POSIX interface can use PCRE without
+modification.
+
+9. Added a new function, pcre_fullinfo() with an extensible interface. It can
+return all that pcre_info() returns, plus additional data. The pcre_info()
+function is retained for compatibility, but is considered to be obsolete.
+
+10. Added experimental recursion feature (?R) to handle one common case that
+Perl 5.6 will be able to do with (?p{...}).
+
+11. Added support for POSIX character classes like [:alpha:], which Perl is
+adopting.
+
+
+Version 2.08 31-Aug-99
+----------------------
+
+1. When startoffset was not zero and the pattern began with ".*", PCRE was not
+trying to match at the startoffset position, but instead was moving forward to
+the next newline as if a previous match had failed.
+
+2. pcretest was not making use of PCRE_NOTEMPTY when repeating for /g and /G,
+and could get into a loop if a null string was matched other than at the start
+of the subject.
+
+3. Added definitions of PCRE_MAJOR and PCRE_MINOR to pcre.h so the version can
+be distinguished at compile time, and for completeness also added PCRE_DATE.
+
+5. Added Paul Sokolovsky's minor changes to make it easy to compile a Win32 DLL
+in GnuWin32 environments.
+
+
+Version 2.07 29-Jul-99
+----------------------
+
+1. The documentation is now supplied in plain text form and HTML as well as in
+the form of man page sources.
+
+2. C++ compilers don't like assigning (void *) values to other pointer types.
+In particular this affects malloc(). Although there is no problem in Standard
+C, I've put in casts to keep C++ compilers happy.
+
+3. Typo on pcretest.c; a cast of (unsigned char *) in the POSIX regexec() call
+should be (const char *).
+
+4. If NOPOSIX is defined, pcretest.c compiles without POSIX support. This may
+be useful for non-Unix systems who don't want to bother with the POSIX stuff.
+However, I haven't made this a standard facility. The documentation doesn't
+mention it, and the Makefile doesn't support it.
+
+5. The Makefile now contains an "install" target, with editable destinations at
+the top of the file. The pcretest program is not installed.
+
+6. pgrep -V now gives the PCRE version number and date.
+
+7. Fixed bug: a zero repetition after a literal string (e.g. /abcde{0}/) was
+causing the entire string to be ignored, instead of just the last character.
+
+8. If a pattern like /"([^\\"]+|\\.)*"/ is applied in the normal way to a
+non-matching string, it can take a very, very long time, even for strings of
+quite modest length, because of the nested recursion. PCRE now does better in
+some of these cases. It does this by remembering the last required literal
+character in the pattern, and pre-searching the subject to ensure it is present
+before running the real match. In other words, it applies a heuristic to detect
+some types of certain failure quickly, and in the above example, if presented
+with a string that has no trailing " it gives "no match" very quickly.
+
+9. A new runtime option PCRE_NOTEMPTY causes null string matches to be ignored;
+other alternatives are tried instead.
+
+
+Version 2.06 09-Jun-99
+----------------------
+
+1. Change pcretest's output for amount of store used to show just the code
+space, because the remainder (the data block) varies in size between 32-bit and
+64-bit systems.
+
+2. Added an extra argument to pcre_exec() to supply an offset in the subject to
+start matching at. This allows lookbehinds to work when searching for multiple
+occurrences in a string.
+
+3. Added additional options to pcretest for testing multiple occurrences:
+
+ /+ outputs the rest of the string that follows a match
+ /g loops for multiple occurrences, using the new startoffset argument
+ /G loops for multiple occurrences by passing an incremented pointer
+
+4. PCRE wasn't doing the "first character" optimization for patterns starting
+with \b or \B, though it was doing it for other lookbehind assertions. That is,
+it wasn't noticing that a match for a pattern such as /\bxyz/ has to start with
+the letter 'x'. On long subject strings, this gives a significant speed-up.
+
+
+Version 2.05 21-Apr-99
+----------------------
+
+1. Changed the type of magic_number from int to long int so that it works
+properly on 16-bit systems.
+
+2. Fixed a bug which caused patterns starting with .* not to work correctly
+when the subject string contained newline characters. PCRE was assuming
+anchoring for such patterns in all cases, which is not correct because .* will
+not pass a newline unless PCRE_DOTALL is set. It now assumes anchoring only if
+DOTALL is set at top level; otherwise it knows that patterns starting with .*
+must be retried after every newline in the subject.
+
+
+Version 2.04 18-Feb-99
+----------------------
+
+1. For parenthesized subpatterns with repeats whose minimum was zero, the
+computation of the store needed to hold the pattern was incorrect (too large).
+If such patterns were nested a few deep, this could multiply and become a real
+problem.
+
+2. Added /M option to pcretest to show the memory requirement of a specific
+pattern. Made -m a synonym of -s (which does this globally) for compatibility.
+
+3. Subpatterns of the form (regex){n,m} (i.e. limited maximum) were being
+compiled in such a way that the backtracking after subsequent failure was
+pessimal. Something like (a){0,3} was compiled as (a)?(a)?(a)? instead of
+((a)((a)(a)?)?)? with disastrous performance if the maximum was of any size.
+
+
+Version 2.03 02-Feb-99
+----------------------
+
+1. Fixed typo and small mistake in man page.
+
+2. Added 4th condition (GPL supersedes if conflict) and created separate
+LICENCE file containing the conditions.
+
+3. Updated pcretest so that patterns such as /abc\/def/ work like they do in
+Perl, that is the internal \ allows the delimiter to be included in the
+pattern. Locked out the use of \ as a delimiter. If \ immediately follows
+the final delimiter, add \ to the end of the pattern (to test the error).
+
+4. Added the convenience functions for extracting substrings after a successful
+match. Updated pcretest to make it able to test these functions.
+
+
+Version 2.02 14-Jan-99
+----------------------
+
+1. Initialized the working variables associated with each extraction so that
+their saving and restoring doesn't refer to uninitialized store.
+
+2. Put dummy code into study.c in order to trick the optimizer of the IBM C
+compiler for OS/2 into generating correct code. Apparently IBM isn't going to
+fix the problem.
+
+3. Pcretest: the timing code wasn't using LOOPREPEAT for timing execution
+calls, and wasn't printing the correct value for compiling calls. Increased the
+default value of LOOPREPEAT, and the number of significant figures in the
+times.
+
+4. Changed "/bin/rm" in the Makefile to "-rm" so it works on Windows NT.
+
+5. Renamed "deftables" as "dftables" to get it down to 8 characters, to avoid
+a building problem on Windows NT with a FAT file system.
+
+
+Version 2.01 21-Oct-98
+----------------------
+
+1. Changed the API for pcre_compile() to allow for the provision of a pointer
+to character tables built by pcre_maketables() in the current locale. If NULL
+is passed, the default tables are used.
+
+
+Version 2.00 24-Sep-98
+----------------------
+
+1. Since the (>?) facility is in Perl 5.005, don't require PCRE_EXTRA to enable
+it any more.
+
+2. Allow quantification of (?>) groups, and make it work correctly.
+
+3. The first character computation wasn't working for (?>) groups.
+
+4. Correct the implementation of \Z (it is permitted to match on the \n at the
+end of the subject) and add 5.005's \z, which really does match only at the
+very end of the subject.
+
+5. Remove the \X "cut" facility; Perl doesn't have it, and (?> is neater.
+
+6. Remove the ability to specify CASELESS, MULTILINE, DOTALL, and
+DOLLAR_END_ONLY at runtime, to make it possible to implement the Perl 5.005
+localized options. All options to pcre_study() were also removed.
+
+7. Add other new features from 5.005:
+
+ $(?<= positive lookbehind
+ $(?<! negative lookbehind
+ (?imsx-imsx) added the unsetting capability
+ such a setting is global if at outer level; local otherwise
+ (?imsx-imsx:) non-capturing groups with option setting
+ (?(cond)re|re) conditional pattern matching
+
+ A backreference to itself in a repeated group matches the previous
+ captured string.
+
+8. General tidying up of studying (both automatic and via "study")
+consequential on the addition of new assertions.
+
+9. As in 5.005, unlimited repeated groups that could match an empty substring
+are no longer faulted at compile time. Instead, the loop is forcibly broken at
+runtime if any iteration does actually match an empty substring.
+
+10. Include the RunTest script in the distribution.
+
+11. Added tests from the Perl 5.005_02 distribution. This showed up a few
+discrepancies, some of which were old and were also with respect to 5.004. They
+have now been fixed.
+
+
+Version 1.09 28-Apr-98
+----------------------
+
+1. A negated single character class followed by a quantifier with a minimum
+value of one (e.g. [^x]{1,6} ) was not compiled correctly. This could lead to
+program crashes, or just wrong answers. This did not apply to negated classes
+containing more than one character, or to minima other than one.
+
+
+Version 1.08 27-Mar-98
+----------------------
+
+1. Add PCRE_UNGREEDY to invert the greediness of quantifiers.
+
+2. Add (?U) and (?X) to set PCRE_UNGREEDY and PCRE_EXTRA respectively. The
+latter must appear before anything that relies on it in the pattern.
+
+
+Version 1.07 16-Feb-98
+----------------------
+
+1. A pattern such as /((a)*)*/ was not being diagnosed as in error (unlimited
+repeat of a potentially empty string).
+
+
+Version 1.06 23-Jan-98
+----------------------
+
+1. Added Markus Oberhumer's little patches for C++.
+
+2. Literal strings longer than 255 characters were broken.
+
+
+Version 1.05 23-Dec-97
+----------------------
+
+1. Negated character classes containing more than one character were failing if
+PCRE_CASELESS was set at run time.
+
+
+Version 1.04 19-Dec-97
+----------------------
+
+1. Corrected the man page, where some "const" qualifiers had been omitted.
+
+2. Made debugging output print "{0,xxx}" instead of just "{,xxx}" to agree with
+input syntax.
+
+3. Fixed memory leak which occurred when a regex with back references was
+matched with an offsets vector that wasn't big enough. The temporary memory
+that is used in this case wasn't being freed if the match failed.
+
+4. Tidied pcretest to ensure it frees memory that it gets.
+
+5. Temporary memory was being obtained in the case where the passed offsets
+vector was exactly big enough.
+
+6. Corrected definition of offsetof() from change 5 below.
+
+7. I had screwed up change 6 below and broken the rules for the use of
+setjmp(). Now fixed.
+
+
+Version 1.03 18-Dec-97
+----------------------
+
+1. A erroneous regex with a missing opening parenthesis was correctly
+diagnosed, but PCRE attempted to access brastack[-1], which could cause crashes
+on some systems.
+
+2. Replaced offsetof(real_pcre, code) by offsetof(real_pcre, code[0]) because
+it was reported that one broken compiler failed on the former because "code" is
+also an independent variable.
+
+3. The erroneous regex a[]b caused an array overrun reference.
+
+4. A regex ending with a one-character negative class (e.g. /[^k]$/) did not
+fail on data ending with that character. (It was going on too far, and checking
+the next character, typically a binary zero.) This was specific to the
+optimized code for single-character negative classes.
+
+5. Added a contributed patch from the TIN world which does the following:
+
+ + Add an undef for memmove, in case the the system defines a macro for it.
+
+ + Add a definition of offsetof(), in case there isn't one. (I don't know
+ the reason behind this - offsetof() is part of the ANSI standard - but
+ it does no harm).
+
+ + Reduce the ifdef's in pcre.c using macro DPRINTF, thereby eliminating
+ most of the places where whitespace preceded '#'. I have given up and
+ allowed the remaining 2 cases to be at the margin.
+
+ + Rename some variables in pcre to eliminate shadowing. This seems very
+ pedantic, but does no harm, of course.
+
+6. Moved the call to setjmp() into its own function, to get rid of warnings
+from gcc -Wall, and avoided calling it at all unless PCRE_EXTRA is used.
+
+7. Constructs such as \d{8,} were compiling into the equivalent of
+\d{8}\d{0,65527} instead of \d{8}\d* which didn't make much difference to the
+outcome, but in this particular case used more store than had been allocated,
+which caused the bug to be discovered because it threw up an internal error.
+
+8. The debugging code in both pcre and pcretest for outputting the compiled
+form of a regex was going wrong in the case of back references followed by
+curly-bracketed repeats.
+
+
+Version 1.02 12-Dec-97
+----------------------
+
+1. Typos in pcre.3 and comments in the source fixed.
+
+2. Applied a contributed patch to get rid of places where it used to remove
+'const' from variables, and fixed some signed/unsigned and uninitialized
+variable warnings.
+
+3. Added the "runtest" target to Makefile.
+
+4. Set default compiler flag to -O2 rather than just -O.
+
+
+Version 1.01 19-Nov-97
+----------------------
+
+1. PCRE was failing to diagnose unlimited repeat of empty string for patterns
+like /([ab]*)*/, that is, for classes with more than one character in them.
+
+2. Likewise, it wasn't diagnosing patterns with "once-only" subpatterns, such
+as /((?>a*))*/ (a PCRE_EXTRA facility).
+
+
+Version 1.00 18-Nov-97
+----------------------
+
+1. Added compile-time macros to support systems such as SunOS4 which don't have
+memmove() or strerror() but have other things that can be used instead.
+
+2. Arranged that "make clean" removes the executables.
+
+
+Version 0.99 27-Oct-97
+----------------------
+
+1. Fixed bug in code for optimizing classes with only one character. It was
+initializing a 32-byte map regardless, which could cause it to run off the end
+of the memory it had got.
+
+2. Added, conditional on PCRE_EXTRA, the proposed (?>REGEX) construction.
+
+
+Version 0.98 22-Oct-97
+----------------------
+
+1. Fixed bug in code for handling temporary memory usage when there are more
+back references than supplied space in the ovector. This could cause segfaults.
+
+
+Version 0.97 21-Oct-97
+----------------------
+
+1. Added the \X "cut" facility, conditional on PCRE_EXTRA.
+
+2. Optimized negated single characters not to use a bit map.
+
+3. Brought error texts together as macro definitions; clarified some of them;
+fixed one that was wrong - it said "range out of order" when it meant "invalid
+escape sequence".
+
+4. Changed some char * arguments to const char *.
+
+5. Added PCRE_NOTBOL and PCRE_NOTEOL (from POSIX).
+
+6. Added the POSIX-style API wrapper in pcreposix.a and testing facilities in
+pcretest.
+
+
+Version 0.96 16-Oct-97
+----------------------
+
+1. Added a simple "pgrep" utility to the distribution.
+
+2. Fixed an incompatibility with Perl: "{" is now treated as a normal character
+unless it appears in one of the precise forms "{ddd}", "{ddd,}", or "{ddd,ddd}"
+where "ddd" means "one or more decimal digits".
+
+3. Fixed serious bug. If a pattern had a back reference, but the call to
+pcre_exec() didn't supply a large enough ovector to record the related
+identifying subpattern, the match always failed. PCRE now remembers the number
+of the largest back reference, and gets some temporary memory in which to save
+the offsets during matching if necessary, in order to ensure that
+backreferences always work.
+
+4. Increased the compatibility with Perl in a number of ways:
+
+ (a) . no longer matches \n by default; an option PCRE_DOTALL is provided
+ to request this handling. The option can be set at compile or exec time.
+
+ (b) $ matches before a terminating newline by default; an option
+ PCRE_DOLLAR_ENDONLY is provided to override this (but not in multiline
+ mode). The option can be set at compile or exec time.
+
+ (c) The handling of \ followed by a digit other than 0 is now supposed to be
+ the same as Perl's. If the decimal number it represents is less than 10
+ or there aren't that many previous left capturing parentheses, an octal
+ escape is read. Inside a character class, it's always an octal escape,
+ even if it is a single digit.
+
+ (d) An escaped but undefined alphabetic character is taken as a literal,
+ unless PCRE_EXTRA is set. Currently this just reserves the remaining
+ escapes.
+
+ (e) {0} is now permitted. (The previous item is removed from the compiled
+ pattern).
+
+5. Changed all the names of code files so that the basic parts are no longer
+than 10 characters, and abolished the teeny "globals.c" file.
+
+6. Changed the handling of character classes; they are now done with a 32-byte
+bit map always.
+
+7. Added the -d and /D options to pcretest to make it possible to look at the
+internals of compilation without having to recompile pcre.
+
+
+Version 0.95 23-Sep-97
+----------------------
+
+1. Fixed bug in pre-pass concerning escaped "normal" characters such as \x5c or
+\x20 at the start of a run of normal characters. These were being treated as
+real characters, instead of the source characters being re-checked.
+
+
+Version 0.94 18-Sep-97
+----------------------
+
+1. The functions are now thread-safe, with the caveat that the global variables
+containing pointers to malloc() and free() or alternative functions are the
+same for all threads.
+
+2. Get pcre_study() to generate a bitmap of initial characters for non-
+anchored patterns when this is possible, and use it if passed to pcre_exec().
+
+
+Version 0.93 15-Sep-97
+----------------------
+
+1. /(b)|(:+)/ was computing an incorrect first character.
+
+2. Add pcre_study() to the API and the passing of pcre_extra to pcre_exec(),
+but not actually doing anything yet.
+
+3. Treat "-" characters in classes that cannot be part of ranges as literals,
+as Perl does (e.g. [-az] or [az-]).
+
+4. Set the anchored flag if a branch starts with .* or .*? because that tests
+all possible positions.
+
+5. Split up into different modules to avoid including unneeded functions in a
+compiled binary. However, compile and exec are still in one module. The "study"
+function is split off.
+
+6. The character tables are now in a separate module whose source is generated
+by an auxiliary program - but can then be edited by hand if required. There are
+now no calls to isalnum(), isspace(), isdigit(), isxdigit(), tolower() or
+toupper() in the code.
+
+7. Turn the malloc/free funtions variables into pcre_malloc and pcre_free and
+make them global. Abolish the function for setting them, as the caller can now
+set them directly.
+
+
+Version 0.92 11-Sep-97
+----------------------
+
+1. A repeat with a fixed maximum and a minimum of 1 for an ordinary character
+(e.g. /a{1,3}/) was broken (I mis-optimized it).
+
+2. Caseless matching was not working in character classes if the characters in
+the pattern were in upper case.
+
+3. Make ranges like [W-c] work in the same way as Perl for caseless matching.
+
+4. Make PCRE_ANCHORED public and accept as a compile option.
+
+5. Add an options word to pcre_exec() and accept PCRE_ANCHORED and
+PCRE_CASELESS at run time. Add escapes \A and \I to pcretest to cause it to
+pass them.
+
+6. Give an error if bad option bits passed at compile or run time.
+
+7. Add PCRE_MULTILINE at compile and exec time, and (?m) as well. Add \M to
+pcretest to cause it to pass that flag.
+
+8. Add pcre_info(), to get the number of identifying subpatterns, the stored
+options, and the first character, if set.
+
+9. Recognize C+ or C{n,m} where n >= 1 as providing a fixed starting character.
+
+
+Version 0.91 10-Sep-97
+----------------------
+
+1. PCRE was failing to diagnose unlimited repeats of subpatterns that could
+match the empty string as in /(a*)*/. It was looping and ultimately crashing.
+
+2. PCRE was looping on encountering an indefinitely repeated back reference to
+a subpattern that had matched an empty string, e.g. /(a|)\1*/. It now does what
+Perl does - treats the match as successful.

+Basic Installation
+==================
+
+ These are generic installation instructions that apply to systems that
+can run the `configure' shell script - Unix systems and any that imitate
+it. They are not specific to PCRE. There are PCRE-specific instructions
+for non-Unix systems in the file NON-UNIX-USE.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+News about PCRE releases
+------------------------
+
+Release 3.5 15-Aug-01
+---------------------
+
+1. The configuring system has been upgraded to use later versions of autoconf
+and libtool. By default it builds both a shared and a static library if the OS
+supports it. You can use --disable-shared or --disable-static on the configure
+command if you want only one of them.
+
+2. The pcretest utility is now installed along with pcregrep because it is
+useful for users (to test regexs) and by doing this, it automatically gets
+relinked by libtool. The documentation has been turned into a man page, so
+there are now .1, .txt, and .html versions in /doc.
+
+3. Upgrades to pcregrep:
+ (i) Added long-form option names like gnu grep.
+ (ii) Added --help to list all options with an explanatory phrase.
+ (iii) Added -r, --recursive to recurse into sub-directories.
+ (iv) Added -f, --file to read patterns from a file.
+
+4. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure
+script, to force use of CR or LF instead of \n in the source. On non-Unix
+systems, the value can be set in config.h.
+
+5. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an
+absolute limit. Changed the text of the error message to make this clear, and
+likewise updated the man page.
+
+6. The limit of 99 on the number of capturing subpatterns has been removed.
+The new limit is 65535, which I hope will not be a "real" limit.
+
+
+Release 3.3 01-Aug-00
+---------------------
+
+There is some support for UTF-8 character strings. This is incomplete and
+experimental. The documentation describes what is and what is not implemented.
+Otherwise, this is just a bug-fixing release.
+
+
+Release 3.0 01-Feb-00
+---------------------
+
+1. A "configure" script is now used to configure PCRE for Unix systems. It
+builds a Makefile, a config.h file, and the pcre-config script.
+
+2. PCRE is built as a shared library by default.
+
+3. There is support for POSIX classes such as [:alpha:].
+
+5. There is an experimental recursion feature.
+
+----------------------------------------------------------------------------
+ IMPORTANT FOR THOSE UPGRADING FROM VERSIONS BEFORE 2.00
+
+Please note that there has been a change in the API such that a larger
+ovector is required at matching time, to provide some additional workspace.
+The new man page has details. This change was necessary in order to support
+some of the new functionality in Perl 5.005.
+
+ IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.00
+
+Another (I hope this is the last!) change has been made to the API for the
+pcre_compile() function. An additional argument has been added to make it
+possible to pass over a pointer to character tables built in the current
+locale by pcre_maketables(). To use the default tables, this new arguement
+should be passed as NULL.
+
+ IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.05
+
+Yet another (and again I hope this really is the last) change has been made
+to the API for the pcre_exec() function. An additional argument has been
+added to make it possible to start the match other than at the start of the
+subject string. This is important if there are lookbehinds. The new man
+page has the details, but you just want to convert existing programs, all
+you need to do is to stick in a new fifth argument to pcre_exec(), with a
+value of zero. For example, change
+
+ pcre_exec(pattern, extra, subject, length, options, ovec, ovecsize)
+to
+ pcre_exec(pattern, extra, subject, length, 0, options, ovec, ovecsize)

+Compiling PCRE on non-Unix systems
+----------------------------------
+
+If you want to compile PCRE for a non-Unix system, note that it consists
+entirely of code written in Standard C, and so should compile successfully
+on any machine with a Standard C compiler and library, using normal compiling
+commands to do the following:
+
+(1) Copy or rename the file config.in as config.h, and change the macros that
+define HAVE_STRERROR and HAVE_MEMMOVE to define them as 1 rather than 0.
+Unfortunately, because of the way Unix autoconf works, the default setting has
+to be 0. You may also want to make changes to other macros in config.h. In
+particular, if you want to force a specific value for newline, you can define
+the NEWLINE macro. The default is to use '\n', thereby using whatever value
+your compiler gives to '\n'.
+
+(2) Copy or rename the file pcre.in as pcre.h, and change the macro definitions
+for PCRE_MAJOR, PCRE_MINOR, and PCRE_DATE near its start to the values set in
+configure.in.
+
+(3) Compile dftables.c as a stand-alone program, and then run it with
+the standard output sent to chartables.c. This generates a set of standard
+character tables.
+
+(4) Compile maketables.c, get.c, study.c and pcre.c and link them all
+together into an object library in whichever form your system keeps such
+libraries. This is the pcre library (chartables.c gets included by means of an
+#include directive).
+
+(5) Similarly, compile pcreposix.c and link it as the pcreposix library.
+
+(6) Compile the test program pcretest.c. This needs the functions in the
+pcre and pcreposix libraries when linking.
+
+(7) Run pcretest on the testinput files in the testdata directory, and check
+that the output matches the corresponding testoutput files. You must use the
+-i option when checking testinput2.
+
+If you have a system without "configure" but where you can use a Makefile, edit
+Makefile.in to create Makefile, substituting suitable values for the variables
+at the head of the file.
+
+Some help in building a Win32 DLL of PCRE in GnuWin32 environments was
+contributed by Paul.Sokolovsky@technologist.com. These environments are
+Mingw32 (http://www.xraylith.wisc.edu/~khan/software/gnu-win32/) and
+CygWin (http://sourceware.cygnus.com/cygwin/). Paul comments:
+
+ For CygWin, set CFLAGS=-mno-cygwin, and do 'make dll'. You'll get
+ pcre.dll (containing pcreposix also), libpcre.dll.a, and dynamically
+ linked pgrep and pcretest. If you have /bin/sh, run RunTest (three
+ main test go ok, locale not supported).

+README file for PCRE (Perl-compatible regular expression library)
+-----------------------------------------------------------------
+
+The latest release of PCRE is always available from
+
+ ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-xxx.tar.gz
+
+Please read the NEWS file if you are upgrading from a previous release.
+
+PCRE has its own native API, but a set of "wrapper" functions that are based on
+the POSIX API are also supplied in the library libpcreposix. Note that this
+just provides a POSIX calling interface to PCRE: the regular expressions
+themselves still follow Perl syntax and semantics. The header file
+for the POSIX-style functions is called pcreposix.h. The official POSIX name is
+regex.h, but I didn't want to risk possible problems with existing files of
+that name by distributing it that way. To use it with an existing program that
+uses the POSIX API, it will have to be renamed or pointed at by a link.
+
+
+Contributions by users of PCRE
+------------------------------
+
+You can find contributions from PCRE users in the directory
+
+ ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib
+
+where there is also a README file giving brief descriptions of what they are.
+Several of them provide support for compiling PCRE on various flavours of
+Windows systems (I myself do not use Windows). Some are complete in themselves;
+others are pointers to URLs containing relevant files.
+
+
+Building PCRE on a Unix system
+------------------------------
+
+To build PCRE on a Unix system, first run the "configure" command from the PCRE
+distribution directory, with your current directory set to the directory where
+you want the files to be created. This command is a standard GNU "autoconf"
+configuration script, for which generic instructions are supplied in INSTALL.
+
+Most commonly, people build PCRE within its own distribution directory, and in
+this case, on many systems, just running "./configure" is sufficient, but the
+usual methods of changing standard defaults are available. For example,
+
+CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
+
+specifies that the C compiler should be run with the flags '-O2 -Wall' instead
+of the default, and that "make install" should install PCRE under /opt/local
+instead of the default /usr/local.
+
+If you want to build in a different directory, just run "configure" with that
+directory as current. For example, suppose you have unpacked the PCRE source
+into /source/pcre/pcre-xxx, but you want to build it in /build/pcre/pcre-xxx:
+
+cd /build/pcre/pcre-xxx
+/source/pcre/pcre-xxx/configure
+
+If you want to make use of the experimential, incomplete support for UTF-8
+character strings in PCRE, you must add --enable-utf8 to the "configure"
+command. Without it, the code for handling UTF-8 is not included in the
+library. (Even when included, it still has to be enabled by an option at run
+time.)
+
+The "configure" script builds five files:
+
+. libtool is a script that builds shared and/or static libraries
+. Makefile is built by copying Makefile.in and making substitutions.
+. config.h is built by copying config.in and making substitutions.
+. pcre-config is built by copying pcre-config.in and making substitutions.
+. RunTest is a script for running tests
+
+Once "configure" has run, you can run "make". It builds two libraries called
+libpcre and libpcreposix, a test program called pcretest, and the pcregrep
+command. You can use "make install" to copy these, the public header files
+pcre.h and pcreposix.h, and the man pages to appropriate live directories on
+your system, in the normal way.
+
+Running "make install" also installs the command pcre-config, which can be used
+to recall information about the PCRE configuration and installation. For
+example,
+
+ pcre-config --version
+
+prints the version number, and
+
+ pcre-config --libs
+
+outputs information about where the library is installed. This command can be
+included in makefiles for programs that use PCRE, saving the programmer from
+having to remember too many details.
+
+There is one esoteric feature that is controlled by "configure". It concerns
+the character value used for "newline", and is something that you probably do
+not want to change on a Unix system. The default is to use whatever value your
+compiler gives to '\n'. By using --enable-newline-is-cr or
+--enable-newline-is-lf you can force the value to be CR (13) or LF (10) if you
+really want to.
+
+
+Shared libraries on Unix systems
+--------------------------------
+
+The default distribution builds PCRE as two shared libraries and two static
+libraries, as long as the operating system supports shared libraries. Shared
+library support relies on the "libtool" script which is built as part of the
+"configure" process.
+
+The libtool script is used to compile and link both shared and static
+libraries. They are placed in a subdirectory called .libs when they are newly
+built. The programs pcretest and pcregrep are built to use these uninstalled
+libraries (by means of wrapper scripts in the case of shared libraries). When
+you use "make install" to install shared libraries, pcregrep and pcretest are
+automatically re-built to use the newly installed shared libraries before being
+installed themselves. However, the versions left in the source directory still
+use the uninstalled libraries.
+
+To build PCRE using static libraries only you must use --disable-shared when
+configuring it. For example
+
+./configure --prefix=/usr/gnu --disable-shared
+
+Then run "make" in the usual way. Similarly, you can use --disable-static to
+build only shared libraries.
+
+
+Building on non-Unix systems
+----------------------------
+
+For a non-Unix system, read the comments in the file NON-UNIX-USE. PCRE has
+been compiled on Windows systems and on Macintoshes, but I don't know the
+details because I don't use those systems. It should be straightforward to
+build PCRE on any system that has a Standard C compiler, because it uses only
+Standard C functions.
+
+
+Testing PCRE
+------------
+
+To test PCRE on a Unix system, run the RunTest script that is created by the
+configuring process. (This can also be run by "make runtest", "make check", or
+"make test".) For other systems, see the instruction in NON-UNIX-USE.
+
+The script runs the pcretest test program (which is documented in the doc
+directory) on each of the testinput files (in the testdata directory) in turn,
+and compares the output with the contents of the corresponding testoutput file.
+A file called testtry is used to hold the output from pcretest. To run pcretest
+on just one of the test files, give its number as an argument to RunTest, for
+example:
+
+ RunTest 3
+
+The first and third test files can also be fed directly into the perltest
+script to check that Perl gives the same results. The third file requires the
+additional features of release 5.005, which is why it is kept separate from the
+main test input, which needs only Perl 5.004. In the long run, when 5.005 (or
+higher) is widespread, these two test files may get amalgamated.
+
+The second set of tests check pcre_fullinfo(), pcre_info(), pcre_study(),
+pcre_copy_substring(), pcre_get_substring(), pcre_get_substring_list(), error
+detection, and run-time flags that are specific to PCRE, as well as the POSIX
+wrapper API. It also uses the debugging flag to check some of the internals of
+pcre_compile().
+
+If you build PCRE with a locale setting that is not the standard C locale, the
+character tables may be different (see next paragraph). In some cases, this may
+cause failures in the second set of tests. For example, in a locale where the
+isprint() function yields TRUE for characters in the range 128-255, the use of
+[:isascii:] inside a character class defines a different set of characters, and
+this shows up in this test as a difference in the compiled code, which is being
+listed for checking. Where the comparison test output contains [\x00-\x7f] the
+test will contain [\x00-\xff], and similarly in some other cases. This is not a
+bug in PCRE.
+
+The fourth set of tests checks pcre_maketables(), the facility for building a
+set of character tables for a specific locale and using them instead of the
+default tables. The tests make use of the "fr" (French) locale. Before running
+the test, the script checks for the presence of this locale by running the
+"locale" command. If that command fails, or if it doesn't include "fr" in the
+list of available locales, the fourth test cannot be run, and a comment is
+output to say why. If running this test produces instances of the error
+
+ ** Failed to set locale "fr"
+
+in the comparison output, it means that locale is not available on your system,
+despite being listed by "locale". This does not mean that PCRE is broken.
+
+The fifth test checks the experimental, incomplete UTF-8 support. It is not run
+automatically unless PCRE is built with UTF-8 support. This file can be fed
+directly to the perltest8 script, which requires Perl 5.6 or higher. The sixth
+file tests internal UTF-8 features of PCRE that are not relevant to Perl.
+
+
+Character tables
+----------------
+
+PCRE uses four tables for manipulating and identifying characters. The final
+argument of the pcre_compile() function is a pointer to a block of memory
+containing the concatenated tables. A call to pcre_maketables() can be used to
+generate a set of tables in the current locale. If the final argument for
+pcre_compile() is passed as NULL, a set of default tables that is built into
+the binary is used.
+
+The source file called chartables.c contains the default set of tables. This is
+not supplied in the distribution, but is built by the program dftables
+(compiled from dftables.c), which uses the ANSI C character handling functions
+such as isalnum(), isalpha(), isupper(), islower(), etc. to build the table
+sources. This means that the default C locale which is set for your system will
+control the contents of these default tables. You can change the default tables
+by editing chartables.c and then re-building PCRE. If you do this, you should
+probably also edit Makefile to ensure that the file doesn't ever get
+re-generated.
+
+The first two 256-byte tables provide lower casing and case flipping functions,
+respectively. The next table consists of three 32-byte bit maps which identify
+digits, "word" characters, and white space, respectively. These are used when
+building 32-byte bit maps that represent character classes.
+
+The final 256-byte table has bits indicating various character types, as
+follows:
+
+ 1 white space character
+ 2 letter
+ 4 decimal digit
+ 8 hexadecimal digit
+ 16 alphanumeric or '_'
+ 128 regular expression metacharacter or binary zero
+
+You should not alter the set of characters that contain the 128 bit, as that
+will cause PCRE to malfunction.
+
+

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
+ --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
+ --infodir=DIR info documentation [DATAROOTDIR/info]

+ --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
+ --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
+ --disable-shared build PCRE as a static library
+ --enable-utf8 enable UTF8 support (incomplete)
+ --enable-newline-is-cr use CR as the newline character
+ --enable-newline-is-lf use LF as the newline character
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+Technical Notes about PCRE
+--------------------------
+
+Many years ago I implemented some regular expression functions to an algorithm
+suggested by Martin Richards. These were not Unix-like in form, and were quite
+restricted in what they could do by comparison with Perl. The interesting part
+about the algorithm was that the amount of space required to hold the compiled
+form of an expression was known in advance. The code to apply an expression did
+not operate by backtracking, as the Henry Spencer and Perl code does, but
+instead checked all possibilities simultaneously by keeping a list of current
+states and checking all of them as it advanced through the subject string. (In
+the terminology of Jeffrey Friedl's book, it was a "DFA algorithm".) When the
+pattern was all used up, all remaining states were possible matches, and the
+one matching the longest subset of the subject string was chosen. This did not
+necessarily maximize the individual wild portions of the pattern, as is
+expected in Unix and Perl-style regular expressions.
+
+By contrast, the code originally written by Henry Spencer and subsequently
+heavily modified for Perl actually compiles the expression twice: once in a
+dummy mode in order to find out how much store will be needed, and then for
+real. The execution function operates by backtracking and maximizing (or,
+optionally, minimizing in Perl) the amount of the subject that matches
+individual wild portions of the pattern. This is an "NFA algorithm" in Friedl's
+terminology.
+
+For the set of functions that forms PCRE (which are unrelated to those
+mentioned above), I tried at first to invent an algorithm that used an amount
+of store bounded by a multiple of the number of characters in the pattern, to
+save on compiling time. However, because of the greater complexity in Perl
+regular expressions, I couldn't do this. In any case, a first pass through the
+pattern is needed, in order to find internal flag settings like (?i) at top
+level. So PCRE works by running a very degenerate first pass to calculate a
+maximum store size, and then a second pass to do the real compile - which may
+use a bit less than the predicted amount of store. The idea is that this is
+going to turn out faster because the first pass is degenerate and the second
+pass can just store stuff straight into the vector. It does make the compiling
+functions bigger, of course, but they have got quite big anyway to handle all
+the Perl stuff.
+
+The compiled form of a pattern is a vector of bytes, containing items of
+variable length. The first byte in an item is an opcode, and the length of the
+item is either implicit in the opcode or contained in the data bytes which
+follow it. A list of all the opcodes follows:
+
+Opcodes with no following data
+------------------------------
+
+These items are all just one byte long
+
+ OP_END end of pattern
+ OP_ANY match any character
+ OP_SOD match start of data: \A
+ OP_CIRC ^ (start of data, or after \n in multiline)
+ OP_NOT_WORD_BOUNDARY \W
+ OP_WORD_BOUNDARY \w
+ OP_NOT_DIGIT \D
+ OP_DIGIT \d
+ OP_NOT_WHITESPACE \S
+ OP_WHITESPACE \s
+ OP_NOT_WORDCHAR \W
+ OP_WORDCHAR \w
+ OP_EODN match end of data or \n at end: \Z
+ OP_EOD match end of data: \z
+ OP_DOLL $ (end of data, or before \n in multiline)
+ OP_RECURSE match the pattern recursively
+
+
+Repeating single characters
+---------------------------
+
+The common repeats (*, +, ?) when applied to a single character appear as
+two-byte items using the following opcodes:
+
+ OP_STAR
+ OP_MINSTAR
+ OP_PLUS
+ OP_MINPLUS
+ OP_QUERY
+ OP_MINQUERY
+
+Those with "MIN" in their name are the minimizing versions. Each is followed by
+the character that is to be repeated. Other repeats make use of
+
+ OP_UPTO
+ OP_MINUPTO
+ OP_EXACT
+
+which are followed by a two-byte count (most significant first) and the
+repeated character. OP_UPTO matches from 0 to the given number. A repeat with a
+non-zero minimum and a fixed maximum is coded as an OP_EXACT followed by an
+OP_UPTO (or OP_MINUPTO).
+
+
+Repeating character types
+-------------------------
+
+Repeats of things like \d are done exactly as for single characters, except
+that instead of a character, the opcode for the type is stored in the data
+byte. The opcodes are:
+
+ OP_TYPESTAR
+ OP_TYPEMINSTAR
+ OP_TYPEPLUS
+ OP_TYPEMINPLUS
+ OP_TYPEQUERY
+ OP_TYPEMINQUERY
+ OP_TYPEUPTO
+ OP_TYPEMINUPTO
+ OP_TYPEEXACT
+
+
+Matching a character string
+---------------------------
+
+The OP_CHARS opcode is followed by a one-byte count and then that number of
+characters. If there are more than 255 characters in sequence, successive
+instances of OP_CHARS are used.
+
+
+Character classes
+-----------------
+
+OP_CLASS is used for a character class, provided there are at least two
+characters in the class. If there is only one character, OP_CHARS is used for a
+positive class, and OP_NOT for a negative one (that is, for something like
+[^a]). Another set of repeating opcodes (OP_NOTSTAR etc.) are used for a
+repeated, negated, single-character class. The normal ones (OP_STAR etc.) are
+used for a repeated positive single-character class.
+
+OP_CLASS is followed by a 32-byte bit map containing a 1 bit for every
+character that is acceptable. The bits are counted from the least significant
+end of each byte.
+
+
+Back references
+---------------
+
+OP_REF is followed by two bytes containing the reference number.
+
+
+Repeating character classes and back references
+-----------------------------------------------
+
+Single-character classes are handled specially (see above). This applies to
+OP_CLASS and OP_REF. In both cases, the repeat information follows the base
+item. The matching code looks at the following opcode to see if it is one of
+
+ OP_CRSTAR
+ OP_CRMINSTAR
+ OP_CRPLUS
+ OP_CRMINPLUS
+ OP_CRQUERY
+ OP_CRMINQUERY
+ OP_CRRANGE
+ OP_CRMINRANGE
+
+All but the last two are just single-byte items. The others are followed by
+four bytes of data, comprising the minimum and maximum repeat counts.
+
+
+Brackets and alternation
+------------------------
+
+A pair of non-capturing (round) brackets is wrapped round each expression at
+compile time, so alternation always happens in the context of brackets.
+
+Non-capturing brackets use the opcode OP_BRA, while capturing brackets use
+OP_BRA+1, OP_BRA+2, etc. [Note for North Americans: "bracket" to some English
+speakers, including myself, can be round, square, curly, or pointy. Hence this
+usage.]
+
+Originally PCRE was limited to 99 capturing brackets (so as not to use up all
+the opcodes). From release 3.5, there is no limit. What happens is that the
+first ones, up to EXTRACT_BASIC_MAX are handled with separate opcodes, as
+above. If there are more, the opcode is set to EXTRACT_BASIC_MAX+1, and the
+first operation in the bracket is OP_BRANUMBER, followed by a 2-byte bracket
+number. This opcode is ignored while matching, but is fished out when handling
+the bracket itself. (They could have all been done like this, but I was making
+minimal changes.)
+
+A bracket opcode is followed by two bytes which give the offset to the next
+alternative OP_ALT or, if there aren't any branches, to the matching KET
+opcode. Each OP_ALT is followed by two bytes giving the offset to the next one,
+or to the KET opcode.
+
+OP_KET is used for subpatterns that do not repeat indefinitely, while
+OP_KETRMIN and OP_KETRMAX are used for indefinite repetitions, minimally or
+maximally respectively. All three are followed by two bytes giving (as a
+positive number) the offset back to the matching BRA opcode.
+
+If a subpattern is quantified such that it is permitted to match zero times, it
+is preceded by one of OP_BRAZERO or OP_BRAMINZERO. These are single-byte
+opcodes which tell the matcher that skipping this subpattern entirely is a
+valid branch.
+
+A subpattern with an indefinite maximum repetition is replicated in the
+compiled data its minimum number of times (or once with a BRAZERO if the
+minimum is zero), with the final copy terminating with a KETRMIN or KETRMAX as
+appropriate.
+
+A subpattern with a bounded maximum repetition is replicated in a nested
+fashion up to the maximum number of times, with BRAZERO or BRAMINZERO before
+each replication after the minimum, so that, for example, (abc){2,5} is
+compiled as (abc)(abc)((abc)((abc)(abc)?)?)?. The 99 and 200 bracket limits do
+not apply to these internally generated brackets.
+
+
+Assertions
+----------
+
+Forward assertions are just like other subpatterns, but starting with one of
+the opcodes OP_ASSERT or OP_ASSERT_NOT. Backward assertions use the opcodes
+OP_ASSERTBACK and OP_ASSERTBACK_NOT, and the first opcode inside the assertion
+is OP_REVERSE, followed by a two byte count of the number of characters to move
+back the pointer in the subject string. When operating in UTF-8 mode, the count
+is a character count rather than a byte count. A separate count is present in
+each alternative of a lookbehind assertion, allowing them to have different
+fixed lengths.
+
+
+Once-only subpatterns
+---------------------
+
+These are also just like other subpatterns, but they start with the opcode
+OP_ONCE.
+
+
+Conditional subpatterns
+-----------------------
+
+These are like other subpatterns, but they start with the opcode OP_COND. If
+the condition is a back reference, this is stored at the start of the
+subpattern using the opcode OP_CREF followed by two bytes containing the
+reference number. Otherwise, a conditional subpattern will always start with
+one of the assertions.
+
+
+Changing options
+----------------
+
+If any of the /i, /m, or /s options are changed within a parenthesized group,
+an OP_OPT opcode is compiled, followed by one byte containing the new settings
+of these flags. If there are several alternatives in a group, there is an
+occurrence of OP_OPT at the start of all those following the first options
+change, to set appropriate options for the start of the alternative.
+Immediately after the end of the group there is another such item to reset the
+flags to their previous values. Other changes of flag within the pattern can be
+handled entirely at compile time, and so do not cause anything to be put into
+the compiled data.

+.SH DESCRIPTION
+The PCRE library is a set of functions that implement regular expression
+pattern matching using the same syntax and semantics as Perl 5, with just a few
+differences (see below). The current implementation corresponds to Perl 5.005,
+with some additional features from later versions. This includes some
+experimental, incomplete support for UTF-8 encoded strings. Details of exactly
+what is and what is not supported are given below.
+
+PCRE has its own native API, which is described in this document. There is also
+a set of wrapper functions that correspond to the POSIX regular expression API.
+These are described in the \fBpcreposix\fR documentation.
+
+The native API function prototypes are defined in the header file \fBpcre.h\fR,
+and on Unix systems the library itself is called \fBlibpcre.a\fR, so can be
+accessed by adding \fB-lpcre\fR to the command for linking an application which
+calls it. The header file defines the macros PCRE_MAJOR and PCRE_MINOR to
+contain the major and minor release numbers for the library. Applications can
+use these to include support for different releases.
+
+The functions \fBpcre_compile()\fR, \fBpcre_study()\fR, and \fBpcre_exec()\fR
+are used for compiling and matching regular expressions. A sample program that
+demonstrates the simplest way of using them is given in the file
+\fIpcredemo.c\fR. The last section of this man page describes how to run it.
+
+The functions \fBpcre_copy_substring()\fR, \fBpcre_get_substring()\fR, and
+\fBpcre_get_substring_list()\fR are convenience functions for extracting
+captured substrings from a matched subject string; \fBpcre_free_substring()\fR
+and \fBpcre_free_substring_list()\fR are also provided, to free the memory used
+for extracted strings.
+
+The function \fBpcre_maketables()\fR is used (optionally) to build a set of
+character tables in the current locale for passing to \fBpcre_compile()\fR.
+
+The function \fBpcre_fullinfo()\fR is used to find out information about a
+compiled pattern; \fBpcre_info()\fR is an obsolete version which returns only
+some of the available information, but is retained for backwards compatibility.
+The function \fBpcre_version()\fR returns a pointer to a string containing the
+version of PCRE and its date of release.
+
+The global variables \fBpcre_malloc\fR and \fBpcre_free\fR initially contain
+the entry points of the standard \fBmalloc()\fR and \fBfree()\fR functions
+respectively. PCRE calls the memory management functions via these variables,
+so a calling program can replace them if it wishes to intercept the calls. This
+should be done before calling any PCRE functions.
+
+
+.SH MULTI-THREADING
+The PCRE functions can be used in multi-threading applications, with the
+proviso that the memory management functions pointed to by \fBpcre_malloc\fR
+and \fBpcre_free\fR are shared by all threads.
+
+The compiled form of a regular expression is not altered during matching, so
+the same compiled pattern can safely be used by several threads at once.
+
+
+.SH COMPILING A PATTERN
+The function \fBpcre_compile()\fR is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument \fIpattern\fR. A pointer to a single block of memory
+that is obtained via \fBpcre_malloc\fR is returned. This contains the compiled
+code and related data. The \fBpcre\fR type is defined for the returned block;
+this is a typedef for a structure whose contents are not externally defined. It
+is up to the caller to free the memory when it is no longer required.
+
+Although the compiled code of a PCRE regex is relocatable, that is, it does not
+depend on memory location, the complete \fBpcre\fR data block is not
+fully relocatable, because it contains a copy of the \fItableptr\fR argument,
+which is an address (see below).
+
+The size of a compiled pattern is roughly proportional to the length of the
+pattern string, except that each character class (other than those containing
+just a single character, negated or not) requires 33 bytes, and repeat
+quantifiers with a minimum greater than one or a bounded maximum cause the
+relevant portions of the compiled pattern to be replicated.
+
+The \fIoptions\fR argument contains independent bits that affect the
+compilation. It should be zero if no options are required. Some of the options,
+in particular, those that are compatible with Perl, can also be set and unset
+from within the pattern (see the detailed description of regular expressions
+below). For these options, the contents of the \fIoptions\fR argument specifies
+their initial settings at the start of compilation and execution. The
+PCRE_ANCHORED option can be set at the time of matching as well as at compile
+time.
+
+If \fIerrptr\fR is NULL, \fBpcre_compile()\fR returns NULL immediately.
+Otherwise, if compilation of a pattern fails, \fBpcre_compile()\fR returns
+NULL, and sets the variable pointed to by \fIerrptr\fR to point to a textual
+error message. The offset from the start of the pattern to the character where
+the error was discovered is placed in the variable pointed to by
+\fIerroffset\fR, which must not be NULL. If it is, an immediate error is given.
+
+If the final argument, \fItableptr\fR, is NULL, PCRE uses a default set of
+character tables which are built when it is compiled, using the default C
+locale. Otherwise, \fItableptr\fR must be the result of a call to
+\fBpcre_maketables()\fR. See the section on locale support below.
+
+This code fragment shows a typical straightforward call to \fBpcre_compile()\fR:
+
+ pcre *re;
+ const char *error;
+ int erroffset;
+ re = pcre_compile(
+ "^A.*Z", /* the pattern */
+ 0, /* default options */
+ &error, /* for error message */
+ &erroffset, /* for error offset */
+ NULL); /* use default character tables */
+
+The following option bits are defined in the header file:
+
+ PCRE_ANCHORED
+
+If this bit is set, the pattern is forced to be "anchored", that is, it is
+constrained to match only at the start of the string which is being searched
+(the "subject string"). This effect can also be achieved by appropriate
+constructs in the pattern itself, which is the only way to do it in Perl.
+
+ PCRE_CASELESS
+
+If this bit is set, letters in the pattern match both upper and lower case
+letters. It is equivalent to Perl's /i option.
+
+ PCRE_DOLLAR_ENDONLY
+
+If this bit is set, a dollar metacharacter in the pattern matches only at the
+end of the subject string. Without this option, a dollar also matches
+immediately before the final character if it is a newline (but not before any
+other newlines). The PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is
+set. There is no equivalent to this option in Perl.
+
+ PCRE_DOTALL
+
+If this bit is set, a dot metacharater in the pattern matches all characters,
+including newlines. Without it, newlines are excluded. This option is
+equivalent to Perl's /s option. A negative class such as [^a] always matches a
+newline character, independent of the setting of this option.
+
+ PCRE_EXTENDED
+
+If this bit is set, whitespace data characters in the pattern are totally
+ignored except when escaped or inside a character class, and characters between
+an unescaped # outside a character class and the next newline character,
+inclusive, are also ignored. This is equivalent to Perl's /x option, and makes
+it possible to include comments inside complicated patterns. Note, however,
+that this applies only to data characters. Whitespace characters may never
+appear within special character sequences in a pattern, for example within the
+sequence (?( which introduces a conditional subpattern.
+
+ PCRE_EXTRA
+
+This option was invented in order to turn on additional functionality of PCRE
+that is incompatible with Perl, but it is currently of very little use. When
+set, any backslash in a pattern that is followed by a letter that has no
+special meaning causes an error, thus reserving these combinations for future
+expansion. By default, as in Perl, a backslash followed by a letter with no
+special meaning is treated as a literal. There are at present no other features
+controlled by this option. It can also be set by a (?X) option setting within a
+pattern.
+
+ PCRE_MULTILINE
+
+By default, PCRE treats the subject string as consisting of a single "line" of
+characters (even if it actually contains several newlines). The "start of line"
+metacharacter (^) matches only at the start of the string, while the "end of
+line" metacharacter ($) matches only at the end of the string, or before a
+terminating newline (unless PCRE_DOLLAR_ENDONLY is set). This is the same as
+Perl.
+
+When PCRE_MULTILINE it is set, the "start of line" and "end of line" constructs
+match immediately following or immediately before any newline in the subject
+string, respectively, as well as at the very start and end. This is equivalent
+to Perl's /m option. If there are no "\\n" characters in a subject string, or
+no occurrences of ^ or $ in a pattern, setting PCRE_MULTILINE has no
+effect.
+
+ PCRE_UNGREEDY
+
+This option inverts the "greediness" of the quantifiers so that they are not
+greedy by default, but become greedy if followed by "?". It is not compatible
+with Perl. It can also be set by a (?U) option setting within the pattern.
+
+ PCRE_UTF8
+
+This option causes PCRE to regard both the pattern and the subject as strings
+of UTF-8 characters instead of just byte strings. However, it is available only
+if PCRE has been built to include UTF-8 support. If not, the use of this option
+provokes an error. Support for UTF-8 is new, experimental, and incomplete.
+Details of exactly what it entails are given below.
+
+
+.SH STUDYING A PATTERN
+When a pattern is going to be used several times, it is worth spending more
+time analyzing it in order to speed up the time taken for matching. The
+function \fBpcre_study()\fR takes a pointer to a compiled pattern as its first
+argument, and returns a pointer to a \fBpcre_extra\fR block (another typedef
+for a structure with hidden contents) containing additional information about
+the pattern; this can be passed to \fBpcre_exec()\fR. If no additional
+information is available, NULL is returned.
+
+The second argument contains option bits. At present, no options are defined
+for \fBpcre_study()\fR, and this argument should always be zero.
+
+The third argument for \fBpcre_study()\fR is a pointer to an error message. If
+studying succeeds (even if no data is returned), the variable it points to is
+set to NULL. Otherwise it points to a textual error message.
+
+This is a typical call to \fBpcre_study\fR():
+
+ pcre_extra *pe;
+ pe = pcre_study(
+ re, /* result of pcre_compile() */
+ 0, /* no options exist */
+ &error); /* set to NULL or points to a message */
+
+At present, studying a pattern is useful only for non-anchored patterns that do
+not have a single fixed starting character. A bitmap of possible starting
+characters is created.
+
+
+.SH LOCALE SUPPORT
+PCRE handles caseless matching, and determines whether characters are letters,
+digits, or whatever, by reference to a set of tables. The library contains a
+default set of tables which is created in the default C locale when PCRE is
+compiled. This is used when the final argument of \fBpcre_compile()\fR is NULL,
+and is sufficient for many applications.
+
+An alternative set of tables can, however, be supplied. Such tables are built
+by calling the \fBpcre_maketables()\fR function, which has no arguments, in the
+relevant locale. The result can then be passed to \fBpcre_compile()\fR as often
+as necessary. For example, to build and use tables that are appropriate for the
+French locale (where accented characters with codes greater than 128 are
+treated as letters), the following code could be used:
+
+ setlocale(LC_CTYPE, "fr");
+ tables = pcre_maketables();
+ re = pcre_compile(..., tables);
+
+The tables are built in memory that is obtained via \fBpcre_malloc\fR. The
+pointer that is passed to \fBpcre_compile\fR is saved with the compiled
+pattern, and the same tables are used via this pointer by \fBpcre_study()\fR
+and \fBpcre_exec()\fR. Thus for any single pattern, compilation, studying and
+matching all happen in the same locale, but different patterns can be compiled
+in different locales. It is the caller's responsibility to ensure that the
+memory containing the tables remains available for as long as it is needed.
+
+
+.SH INFORMATION ABOUT A PATTERN
+The \fBpcre_fullinfo()\fR function returns information about a compiled
+pattern. It replaces the obsolete \fBpcre_info()\fR function, which is
+nevertheless retained for backwards compability (and is documented below).
+
+The first argument for \fBpcre_fullinfo()\fR is a pointer to the compiled
+pattern. The second argument is the result of \fBpcre_study()\fR, or NULL if
+the pattern was not studied. The third argument specifies which piece of
+information is required, while the fourth argument is a pointer to a variable
+to receive the data. The yield of the function is zero for success, or one of
+the following negative numbers:
+
+ PCRE_ERROR_NULL the argument \fIcode\fR was NULL
+ the argument \fIwhere\fR was NULL
+ PCRE_ERROR_BADMAGIC the "magic number" was not found
+ PCRE_ERROR_BADOPTION the value of \fIwhat\fR was invalid
+
+Here is a typical call of \fBpcre_fullinfo()\fR, to obtain the length of the
+compiled pattern:
+
+ int rc;
+ unsigned long int length;
+ rc = pcre_fullinfo(
+ re, /* result of pcre_compile() */
+ pe, /* result of pcre_study(), or NULL */
+ PCRE_INFO_SIZE, /* what is required */
+ &length); /* where to put the data */
+
+The possible values for the third argument are defined in \fBpcre.h\fR, and are
+as follows:
+
+ PCRE_INFO_OPTIONS
+
+Return a copy of the options with which the pattern was compiled. The fourth
+argument should point to an \fBunsigned long int\fR variable. These option bits
+are those specified in the call to \fBpcre_compile()\fR, modified by any
+top-level option settings within the pattern itself, and with the PCRE_ANCHORED
+bit forcibly set if the form of the pattern implies that it can match only at
+the start of a subject string.
+
+ PCRE_INFO_SIZE
+
+Return the size of the compiled pattern, that is, the value that was passed as
+the argument to \fBpcre_malloc()\fR when PCRE was getting memory in which to
+place the compiled data. The fourth argument should point to a \fBsize_t\fR
+variable.
+
+ PCRE_INFO_CAPTURECOUNT
+
+Return the number of capturing subpatterns in the pattern. The fourth argument
+should point to an \fbint\fR variable.
+
+ PCRE_INFO_BACKREFMAX
+
+Return the number of the highest back reference in the pattern. The fourth
+argument should point to an \fBint\fR variable. Zero is returned if there are
+no back references.
+
+ PCRE_INFO_FIRSTCHAR
+
+Return information about the first character of any matched string, for a
+non-anchored pattern. If there is a fixed first character, e.g. from a pattern
+such as (cat|cow|coyote), it is returned in the integer pointed to by
+\fIwhere\fR. Otherwise, if either
+
+(a) the pattern was compiled with the PCRE_MULTILINE option, and every branch
+starts with "^", or
+
+(b) every branch of the pattern starts with ".*" and PCRE_DOTALL is not set
+(if it were set, the pattern would be anchored),
+
+-1 is returned, indicating that the pattern matches only at the start of a
+subject string or after any "\\n" within the string. Otherwise -2 is returned.
+For anchored patterns, -2 is returned.
+
+ PCRE_INFO_FIRSTTABLE
+
+If the pattern was studied, and this resulted in the construction of a 256-bit
+table indicating a fixed set of characters for the first character in any
+matching string, a pointer to the table is returned. Otherwise NULL is
+returned. The fourth argument should point to an \fBunsigned char *\fR
+variable.
+
+ PCRE_INFO_LASTLITERAL
+
+For a non-anchored pattern, return the value of the rightmost literal character
+which must exist in any matched string, other than at its start. The fourth
+argument should point to an \fBint\fR variable. If there is no such character,
+or if the pattern is anchored, -1 is returned. For example, for the pattern
+/a\\d+z\\d+/ the returned value is 'z'.
+
+The \fBpcre_info()\fR function is now obsolete because its interface is too
+restrictive to return all the available data about a compiled pattern. New
+programs should use \fBpcre_fullinfo()\fR instead. The yield of
+\fBpcre_info()\fR is the number of capturing subpatterns, or one of the
+following negative numbers:
+
+ PCRE_ERROR_NULL the argument \fIcode\fR was NULL
+ PCRE_ERROR_BADMAGIC the "magic number" was not found
+
+If the \fIoptptr\fR argument is not NULL, a copy of the options with which the
+pattern was compiled is placed in the integer it points to (see
+PCRE_INFO_OPTIONS above).
+
+If the pattern is not anchored and the \fIfirstcharptr\fR argument is not NULL,
+it is used to pass back information about the first character of any matched
+string (see PCRE_INFO_FIRSTCHAR above).
+
+
+.SH MATCHING A PATTERN
+The function \fBpcre_exec()\fR is called to match a subject string against a
+pre-compiled pattern, which is passed in the \fIcode\fR argument. If the
+pattern has been studied, the result of the study should be passed in the
+\fIextra\fR argument. Otherwise this must be NULL.
+
+Here is an example of a simple call to \fBpcre_exec()\fR:
+
+ int rc;
+ int ovector[30];
+ rc = pcre_exec(
+ re, /* result of pcre_compile() */
+ NULL, /* we didn't study the pattern */
+ "some string", /* the subject string */
+ 11, /* the length of the subject string */
+ 0, /* start at offset 0 in the subject */
+ 0, /* default options */
+ ovector, /* vector for substring information */
+ 30); /* number of elements in the vector */
+
+The PCRE_ANCHORED option can be passed in the \fIoptions\fR argument, whose
+unused bits must be zero. However, if a pattern was compiled with
+PCRE_ANCHORED, or turned out to be anchored by virtue of its contents, it
+cannot be made unachored at matching time.
+
+There are also three further options that can be set only at matching time:
+
+ PCRE_NOTBOL
+
+The first character of the string is not the beginning of a line, so the
+circumflex metacharacter should not match before it. Setting this without
+PCRE_MULTILINE (at compile time) causes circumflex never to match.
+
+ PCRE_NOTEOL
+
+The end of the string is not the end of a line, so the dollar metacharacter
+should not match it nor (except in multiline mode) a newline immediately before
+it. Setting this without PCRE_MULTILINE (at compile time) causes dollar never
+to match.
+
+ PCRE_NOTEMPTY
+
+An empty string is not considered to be a valid match if this option is set. If
+there are alternatives in the pattern, they are tried. If all the alternatives
+match the empty string, the entire match fails. For example, if the pattern
+
+ a?b?
+
+is applied to a string not beginning with "a" or "b", it matches the empty
+string at the start of the subject. With PCRE_NOTEMPTY set, this match is not
+valid, so PCRE searches further into the string for occurrences of "a" or "b".
+
+Perl has no direct equivalent of PCRE_NOTEMPTY, but it does make a special case
+of a pattern match of the empty string within its \fBsplit()\fR function, and
+when using the /g modifier. It is possible to emulate Perl's behaviour after
+matching a null string by first trying the match again at the same offset with
+PCRE_NOTEMPTY set, and then if that fails by advancing the starting offset (see
+below) and trying an ordinary match again.
+
+The subject string is passed as a pointer in \fIsubject\fR, a length in
+\fIlength\fR, and a starting offset in \fIstartoffset\fR. Unlike the pattern
+string, the subject may contain binary zero characters. When the starting
+offset is zero, the search for a match starts at the beginning of the subject,
+and this is by far the most common case.
+
+A non-zero starting offset is useful when searching for another match in the
+same subject by calling \fBpcre_exec()\fR again after a previous success.
+Setting \fIstartoffset\fR differs from just passing over a shortened string and
+setting PCRE_NOTBOL in the case of a pattern that begins with any kind of
+lookbehind. For example, consider the pattern
+
+ \\Biss\\B
+
+which finds occurrences of "iss" in the middle of words. (\\B matches only if
+the current position in the subject is not a word boundary.) When applied to
+the string "Mississipi" the first call to \fBpcre_exec()\fR finds the first
+occurrence. If \fBpcre_exec()\fR is called again with just the remainder of the
+subject, namely "issipi", it does not match, because \\B is always false at the
+start of the subject, which is deemed to be a word boundary. However, if
+\fBpcre_exec()\fR is passed the entire string again, but with \fIstartoffset\fR
+set to 4, it finds the second occurrence of "iss" because it is able to look
+behind the starting point to discover that it is preceded by a letter.
+
+If a non-zero starting offset is passed when the pattern is anchored, one
+attempt to match at the given offset is tried. This can only succeed if the
+pattern does not require the match to be at the start of the subject.
+
+In general, a pattern matches a certain portion of the subject, and in
+addition, further substrings from the subject may be picked out by parts of the
+pattern. Following the usage in Jeffrey Friedl's book, this is called
+"capturing" in what follows, and the phrase "capturing subpattern" is used for
+a fragment of a pattern that picks out a substring. PCRE supports several other
+kinds of parenthesized subpattern that do not cause substrings to be captured.
+
+Captured substrings are returned to the caller via a vector of integer offsets
+whose address is passed in \fIovector\fR. The number of elements in the vector
+is passed in \fIovecsize\fR. The first two-thirds of the vector is used to pass
+back captured substrings, each substring using a pair of integers. The
+remaining third of the vector is used as workspace by \fBpcre_exec()\fR while
+matching capturing subpatterns, and is not available for passing back
+information. The length passed in \fIovecsize\fR should always be a multiple of
+three. If it is not, it is rounded down.
+
+When a match has been successful, information about captured substrings is
+returned in pairs of integers, starting at the beginning of \fIovector\fR, and
+continuing up to two-thirds of its length at the most. The first element of a
+pair is set to the offset of the first character in a substring, and the second
+is set to the offset of the first character after the end of a substring. The
+first pair, \fIovector[0]\fR and \fIovector[1]\fR, identify the portion of the
+subject string matched by the entire pattern. The next pair is used for the
+first capturing subpattern, and so on. The value returned by \fBpcre_exec()\fR
+is the number of pairs that have been set. If there are no capturing
+subpatterns, the return value from a successful match is 1, indicating that
+just the first pair of offsets has been set.
+
+Some convenience functions are provided for extracting the captured substrings
+as separate strings. These are described in the following section.
+
+It is possible for an capturing subpattern number \fIn+1\fR to match some
+part of the subject when subpattern \fIn\fR has not been used at all. For
+example, if the string "abc" is matched against the pattern (a|(z))(bc)
+subpatterns 1 and 3 are matched, but 2 is not. When this happens, both offset
+values corresponding to the unused subpattern are set to -1.
+
+If a capturing subpattern is matched repeatedly, it is the last portion of the
+string that it matched that gets returned.
+
+If the vector is too small to hold all the captured substrings, it is used as
+far as possible (up to two-thirds of its length), and the function returns a
+value of zero. In particular, if the substring offsets are not of interest,
+\fBpcre_exec()\fR may be called with \fIovector\fR passed as NULL and
+\fIovecsize\fR as zero. However, if the pattern contains back references and
+the \fIovector\fR isn't big enough to remember the related substrings, PCRE has
+to get additional memory for use during matching. Thus it is usually advisable
+to supply an \fIovector\fR.
+
+Note that \fBpcre_info()\fR can be used to find out how many capturing
+subpatterns there are in a compiled pattern. The smallest size for
+\fIovector\fR that will allow for \fIn\fR captured substrings in addition to
+the offsets of the substring matched by the whole pattern is (\fIn\fR+1)*3.
+
+If \fBpcre_exec()\fR fails, it returns a negative number. The following are
+defined in the header file:
+
+ PCRE_ERROR_NOMATCH (-1)
+
+The subject string did not match the pattern.
+
+ PCRE_ERROR_NULL (-2)
+
+Either \fIcode\fR or \fIsubject\fR was passed as NULL, or \fIovector\fR was
+NULL and \fIovecsize\fR was not zero.
+
+ PCRE_ERROR_BADOPTION (-3)
+
+An unrecognized bit was set in the \fIoptions\fR argument.
+
+ PCRE_ERROR_BADMAGIC (-4)
+
+PCRE stores a 4-byte "magic number" at the start of the compiled code, to catch
+the case when it is passed a junk pointer. This is the error it gives when the
+magic number isn't present.
+
+ PCRE_ERROR_UNKNOWN_NODE (-5)
+
+While running the pattern match, an unknown item was encountered in the
+compiled pattern. This error could be caused by a bug in PCRE or by overwriting
+of the compiled pattern.
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+If a pattern contains back references, but the \fIovector\fR that is passed to
+\fBpcre_exec()\fR is not big enough to remember the referenced substrings, PCRE
+gets a block of memory at the start of matching to use for this purpose. If the
+call via \fBpcre_malloc()\fR fails, this error is given. The memory is freed at
+the end of matching.
+
+
+.SH EXTRACTING CAPTURED SUBSTRINGS
+Captured substrings can be accessed directly by using the offsets returned by
+\fBpcre_exec()\fR in \fIovector\fR. For convenience, the functions
+\fBpcre_copy_substring()\fR, \fBpcre_get_substring()\fR, and
+\fBpcre_get_substring_list()\fR are provided for extracting captured substrings
+as new, separate, zero-terminated strings. A substring that contains a binary
+zero is correctly extracted and has a further zero added on the end, but the
+result does not, of course, function as a C string.
+
+The first three arguments are the same for all three functions: \fIsubject\fR
+is the subject string which has just been successfully matched, \fIovector\fR
+is a pointer to the vector of integer offsets that was passed to
+\fBpcre_exec()\fR, and \fIstringcount\fR is the number of substrings that
+were captured by the match, including the substring that matched the entire
+regular expression. This is the value returned by \fBpcre_exec\fR if it
+is greater than zero. If \fBpcre_exec()\fR returned zero, indicating that it
+ran out of space in \fIovector\fR, the value passed as \fIstringcount\fR should
+be the size of the vector divided by three.
+
+The functions \fBpcre_copy_substring()\fR and \fBpcre_get_substring()\fR
+extract a single substring, whose number is given as \fIstringnumber\fR. A
+value of zero extracts the substring that matched the entire pattern, while
+higher values extract the captured substrings. For \fBpcre_copy_substring()\fR,
+the string is placed in \fIbuffer\fR, whose length is given by
+\fIbuffersize\fR, while for \fBpcre_get_substring()\fR a new block of memory is
+obtained via \fBpcre_malloc\fR, and its address is returned via
+\fIstringptr\fR. The yield of the function is the length of the string, not
+including the terminating zero, or one of
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+The buffer was too small for \fBpcre_copy_substring()\fR, or the attempt to get
+memory failed for \fBpcre_get_substring()\fR.
+
+ PCRE_ERROR_NOSUBSTRING (-7)
+
+There is no substring whose number is \fIstringnumber\fR.
+
+The \fBpcre_get_substring_list()\fR function extracts all available substrings
+and builds a list of pointers to them. All this is done in a single block of
+memory which is obtained via \fBpcre_malloc\fR. The address of the memory block
+is returned via \fIlistptr\fR, which is also the start of the list of string
+pointers. The end of the list is marked by a NULL pointer. The yield of the
+function is zero if all went well, or
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+if the attempt to get the memory block failed.
+
+When any of these functions encounter a substring that is unset, which can
+happen when capturing subpattern number \fIn+1\fR matches some part of the
+subject, but subpattern \fIn\fR has not been used at all, they return an empty
+string. This can be distinguished from a genuine zero-length substring by
+inspecting the appropriate offset in \fIovector\fR, which is negative for unset
+substrings.
+
+The two convenience functions \fBpcre_free_substring()\fR and
+\fBpcre_free_substring_list()\fR can be used to free the memory returned by
+a previous call of \fBpcre_get_substring()\fR or
+\fBpcre_get_substring_list()\fR, respectively. They do nothing more than call
+the function pointed to by \fBpcre_free\fR, which of course could be called
+directly from a C program. However, PCRE is used in some situations where it is
+linked via a special interface to another programming language which cannot use
+\fBpcre_free\fR directly; it is for these cases that the functions are
+provided.
+
+
+.SH LIMITATIONS
+There are some size limitations in PCRE but it is hoped that they will never in
+practice be relevant.
+The maximum length of a compiled pattern is 65539 (sic) bytes.
+All values in repeating quantifiers must be less than 65536.
+There maximum number of capturing subpatterns is 65535.
+There is no limit to the number of non-capturing subpatterns, but the maximum
+depth of nesting of all kinds of parenthesized subpattern, including capturing
+subpatterns, assertions, and other types of subpattern, is 200.
+
+The maximum length of a subject string is the largest positive number that an
+integer variable can hold. However, PCRE uses recursion to handle subpatterns
+and indefinite repetition. This means that the available stack space may limit
+the size of a subject string that can be processed by certain patterns.
+
+
+.SH DIFFERENCES FROM PERL
+The differences described here are with respect to Perl 5.005.
+
+1. By default, a whitespace character is any character that the C library
+function \fBisspace()\fR recognizes, though it is possible to compile PCRE with
+alternative character type tables. Normally \fBisspace()\fR matches space,
+formfeed, newline, carriage return, horizontal tab, and vertical tab. Perl 5
+no longer includes vertical tab in its set of whitespace characters. The \\v
+escape that was in the Perl documentation for a long time was never in fact
+recognized. However, the character itself was treated as whitespace at least
+up to 5.002. In 5.004 and 5.005 it does not match \\s.
+
+2. PCRE does not allow repeat quantifiers on lookahead assertions. Perl permits
+them, but they do not mean what you might think. For example, (?!a){3} does
+not assert that the next three characters are not "a". It just asserts that the
+next character is not "a" three times.
+
+3. Capturing subpatterns that occur inside negative lookahead assertions are
+counted, but their entries in the offsets vector are never set. Perl sets its
+numerical variables from any such patterns that are matched before the
+assertion fails to match something (thereby succeeding), but only if the
+negative lookahead assertion contains just one branch.
+
+4. Though binary zero characters are supported in the subject string, they are
+not allowed in a pattern string because it is passed as a normal C string,
+terminated by zero. The escape sequence "\\0" can be used in the pattern to
+represent a binary zero.
+
+5. The following Perl escape sequences are not supported: \\l, \\u, \\L, \\U,
+\\E, \\Q. In fact these are implemented by Perl's general string-handling and
+are not part of its pattern matching engine.
+
+6. The Perl \\G assertion is not supported as it is not relevant to single
+pattern matches.
+
+7. Fairly obviously, PCRE does not support the (?{code}) and (?p{code})
+constructions. However, there is some experimental support for recursive
+patterns using the non-Perl item (?R).
+
+8. There are at the time of writing some oddities in Perl 5.005_02 concerned
+with the settings of captured strings when part of a pattern is repeated. For
+example, matching "aba" against the pattern /^(a(b)?)+$/ sets $2 to the value
+"b", but matching "aabbaa" against /^(aa(bb)?)+$/ leaves $2 unset. However, if
+the pattern is changed to /^(aa(b(b))?)+$/ then $2 (and $3) are set.
+
+In Perl 5.004 $2 is set in both cases, and that is also true of PCRE. If in the
+future Perl changes to a consistent state that is different, PCRE may change to
+follow.
+
+9. Another as yet unresolved discrepancy is that in Perl 5.005_02 the pattern
+/^(a)?(?(1)a|b)+$/ matches the string "a", whereas in PCRE it does not.
+However, in both Perl and PCRE /^(a)?a/ matched against "a" leaves $1 unset.
+
+10. PCRE provides some extensions to the Perl regular expression facilities:
+
+(a) Although lookbehind assertions must match fixed length strings, each
+alternative branch of a lookbehind assertion can match a different length of
+string. Perl 5.005 requires them all to have the same length.
+
+(b) If PCRE_DOLLAR_ENDONLY is set and PCRE_MULTILINE is not set, the $ meta-
+character matches only at the very end of the string.
+
+(c) If PCRE_EXTRA is set, a backslash followed by a letter with no special
+meaning is faulted.
+
+(d) If PCRE_UNGREEDY is set, the greediness of the repetition quantifiers is
+inverted, that is, by default they are not greedy, but if followed by a
+question mark they are.
+
+(e) PCRE_ANCHORED can be used to force a pattern to be tried only at the start
+of the subject.
+
+(f) The PCRE_NOTBOL, PCRE_NOTEOL, and PCRE_NOTEMPTY options for
+\fBpcre_exec()\fR have no Perl equivalents.
+
+(g) The (?R) construct allows for recursive pattern matching (Perl 5.6 can do
+this using the (?p{code}) construct, which PCRE cannot of course support.)
+
+
+.SH REGULAR EXPRESSION DETAILS
+The syntax and semantics of the regular expressions supported by PCRE are
+described below. Regular expressions are also described in the Perl
+documentation and in a number of other books, some of which have copious
+examples. Jeffrey Friedl's "Mastering Regular Expressions", published by
+O'Reilly (ISBN 1-56592-257), covers them in great detail.
+
+The description here is intended as reference documentation. The basic
+operation of PCRE is on strings of bytes. However, there is the beginnings of
+some support for UTF-8 character strings. To use this support you must
+configure PCRE to include it, and then call \fBpcre_compile()\fR with the
+PCRE_UTF8 option. How this affects the pattern matching is described in the
+final section of this document.
+
+A regular expression is a pattern that is matched against a subject string from
+left to right. Most characters stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the pattern
+
+ The quick brown fox
+
+matches a portion of a subject string that is identical to itself. The power of
+regular expressions comes from the ability to include alternatives and
+repetitions in the pattern. These are encoded in the pattern by the use of
+\fImeta-characters\fR, which do not stand for themselves but instead are
+interpreted in some special way.
+
+There are two different sets of meta-characters: those that are recognized
+anywhere in the pattern except within square brackets, and those that are
+recognized in square brackets. Outside square brackets, the meta-characters are
+as follows:
+
+ \\ general escape character with several uses
+ ^ assert start of subject (or line, in multiline mode)
+ $ assert end of subject (or line, in multiline mode)
+ . match any character except newline (by default)
+ [ start character class definition
+ | start of alternative branch
+ ( start subpattern
+ ) end subpattern
+ ? extends the meaning of (
+ also 0 or 1 quantifier
+ also quantifier minimizer
+ * 0 or more quantifier
+ + 1 or more quantifier
+ { start min/max quantifier
+
+Part of a pattern that is in square brackets is called a "character class". In
+a character class the only meta-characters are:
+
+ \\ general escape character
+ ^ negate the class, but only if the first character
+ - indicates character range
+ ] terminates the character class
+
+The following sections describe the use of each of the meta-characters.
+
+
+.SH BACKSLASH
+The backslash character has several uses. Firstly, if it is followed by a
+non-alphameric character, it takes away any special meaning that character may
+have. This use of backslash as an escape character applies both inside and
+outside character classes.
+
+For example, if you want to match a "*" character, you write "\\*" in the
+pattern. This applies whether or not the following character would otherwise be
+interpreted as a meta-character, so it is always safe to precede a
+non-alphameric with "\\" to specify that it stands for itself. In particular,
+if you want to match a backslash, you write "\\\\".
+
+If a pattern is compiled with the PCRE_EXTENDED option, whitespace in the
+pattern (other than in a character class) and characters between a "#" outside
+a character class and the next newline character are ignored. An escaping
+backslash can be used to include a whitespace or "#" character as part of the
+pattern.
+
+A second use of backslash provides a way of encoding non-printing characters
+in patterns in a visible manner. There is no restriction on the appearance of
+non-printing characters, apart from the binary zero that terminates a pattern,
+but when a pattern is being prepared by text editing, it is usually easier to
+use one of the following escape sequences than the binary character it
+represents:
+
+ \\a alarm, that is, the BEL character (hex 07)
+ \\cx "control-x", where x is any character
+ \\e escape (hex 1B)
+ \\f formfeed (hex 0C)
+ \\n newline (hex 0A)
+ \\r carriage return (hex 0D)
+ \\t tab (hex 09)
+ \\xhh character with hex code hh
+ \\ddd character with octal code ddd, or backreference
+
+The precise effect of "\\cx" is as follows: if "x" is a lower case letter, it
+is converted to upper case. Then bit 6 of the character (hex 40) is inverted.
+Thus "\\cz" becomes hex 1A, but "\\c{" becomes hex 3B, while "\\c;" becomes hex
+7B.
+
+After "\\x", up to two hexadecimal digits are read (letters can be in upper or
+lower case).
+
+After "\\0" up to two further octal digits are read. In both cases, if there
+are fewer than two digits, just those that are present are used. Thus the
+sequence "\\0\\x\\07" specifies two binary zeros followed by a BEL character.
+Make sure you supply two digits after the initial zero if the character that
+follows is itself an octal digit.
+
+The handling of a backslash followed by a digit other than 0 is complicated.
+Outside a character class, PCRE reads it and any following digits as a decimal
+number. If the number is less than 10, or if there have been at least that many
+previous capturing left parentheses in the expression, the entire sequence is
+taken as a \fIback reference\fR. A description of how this works is given
+later, following the discussion of parenthesized subpatterns.
+
+Inside a character class, or if the decimal number is greater than 9 and there
+have not been that many capturing subpatterns, PCRE re-reads up to three octal
+digits following the backslash, and generates a single byte from the least
+significant 8 bits of the value. Any subsequent digits stand for themselves.
+For example:
+
+ \\040 is another way of writing a space
+ \\40 is the same, provided there are fewer than 40
+ previous capturing subpatterns
+ \\7 is always a back reference
+ \\11 might be a back reference, or another way of
+ writing a tab
+ \\011 is always a tab
+ \\0113 is a tab followed by the character "3"
+ \\113 is the character with octal code 113 (since there
+ can be no more than 99 back references)
+ \\377 is a byte consisting entirely of 1 bits
+ \\81 is either a back reference, or a binary zero
+ followed by the two characters "8" and "1"
+
+Note that octal values of 100 or greater must not be introduced by a leading
+zero, because no more than three octal digits are ever read.
+
+All the sequences that define a single byte value can be used both inside and
+outside character classes. In addition, inside a character class, the sequence
+"\\b" is interpreted as the backspace character (hex 08). Outside a character
+class it has a different meaning (see below).
+
+The third use of backslash is for specifying generic character types:
+
+ \\d any decimal digit
+ \\D any character that is not a decimal digit
+ \\s any whitespace character
+ \\S any character that is not a whitespace character
+ \\w any "word" character
+ \\W any "non-word" character
+
+Each pair of escape sequences partitions the complete set of characters into
+two disjoint sets. Any given character matches one, and only one, of each pair.
+
+A "word" character is any letter or digit or the underscore character, that is,
+any character which can be part of a Perl "word". The definition of letters and
+digits is controlled by PCRE's character tables, and may vary if locale-
+specific matching is taking place (see "Locale support" above). For example, in
+the "fr" (French) locale, some character codes greater than 128 are used for
+accented letters, and these are matched by \\w.
+
+These character type sequences can appear both inside and outside character
+classes. They each match one character of the appropriate type. If the current
+matching point is at the end of the subject string, all of them fail, since
+there is no character to match.
+
+The fourth use of backslash is for certain simple assertions. An assertion
+specifies a condition that has to be met at a particular point in a match,
+without consuming any characters from the subject string. The use of
+subpatterns for more complicated assertions is described below. The backslashed
+assertions are
+
+ \\b word boundary
+ \\B not a word boundary
+ \\A start of subject (independent of multiline mode)
+ \\Z end of subject or newline at end (independent of multiline mode)
+ \\z end of subject (independent of multiline mode)
+
+These assertions may not appear in character classes (but note that "\\b" has a
+different meaning, namely the backspace character, inside a character class).
+
+A word boundary is a position in the subject string where the current character
+and the previous character do not both match \\w or \\W (i.e. one matches
+\\w and the other matches \\W), or the start or end of the string if the
+first or last character matches \\w, respectively.
+
+The \\A, \\Z, and \\z assertions differ from the traditional circumflex and
+dollar (described below) in that they only ever match at the very start and end
+of the subject string, whatever options are set. They are not affected by the
+PCRE_NOTBOL or PCRE_NOTEOL options. If the \fIstartoffset\fR argument of
+\fBpcre_exec()\fR is non-zero, \\A can never match. The difference between \\Z
+and \\z is that \\Z matches before a newline that is the last character of the
+string as well as at the end of the string, whereas \\z matches only at the
+end.
+
+
+.SH CIRCUMFLEX AND DOLLAR
+Outside a character class, in the default matching mode, the circumflex
+character is an assertion which is true only if the current matching point is
+at the start of the subject string. If the \fIstartoffset\fR argument of
+\fBpcre_exec()\fR is non-zero, circumflex can never match. Inside a character
+class, circumflex has an entirely different meaning (see below).
+
+Circumflex need not be the first character of the pattern if a number of
+alternatives are involved, but it should be the first thing in each alternative
+in which it appears if the pattern is ever to match that branch. If all
+possible alternatives start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is said to be an
+"anchored" pattern. (There are also other constructs that can cause a pattern
+to be anchored.)
+
+A dollar character is an assertion which is true only if the current matching
+point is at the end of the subject string, or immediately before a newline
+character that is the last character in the string (by default). Dollar need
+not be the last character of the pattern if a number of alternatives are
+involved, but it should be the last item in any branch in which it appears.
+Dollar has no special meaning in a character class.
+
+The meaning of dollar can be changed so that it matches only at the very end of
+the string, by setting the PCRE_DOLLAR_ENDONLY option at compile or matching
+time. This does not affect the \\Z assertion.
+
+The meanings of the circumflex and dollar characters are changed if the
+PCRE_MULTILINE option is set. When this is the case, they match immediately
+after and immediately before an internal "\\n" character, respectively, in
+addition to matching at the start and end of the subject string. For example,
+the pattern /^abc$/ matches the subject string "def\\nabc" in multiline mode,
+but not otherwise. Consequently, patterns that are anchored in single line mode
+because all branches start with "^" are not anchored in multiline mode, and a
+match for circumflex is possible when the \fIstartoffset\fR argument of
+\fBpcre_exec()\fR is non-zero. The PCRE_DOLLAR_ENDONLY option is ignored if
+PCRE_MULTILINE is set.
+
+Note that the sequences \\A, \\Z, and \\z can be used to match the start and
+end of the subject in both modes, and if all branches of a pattern start with
+\\A it is always anchored, whether PCRE_MULTILINE is set or not.
+
+
+.SH FULL STOP (PERIOD, DOT)
+Outside a character class, a dot in the pattern matches any one character in
+the subject, including a non-printing character, but not (by default) newline.
+If the PCRE_DOTALL option is set, dots match newlines as well. The handling of
+dot is entirely independent of the handling of circumflex and dollar, the only
+relationship being that they both involve newline characters. Dot has no
+special meaning in a character class.
+
+
+.SH SQUARE BRACKETS
+An opening square bracket introduces a character class, terminated by a closing
+square bracket. A closing square bracket on its own is not special. If a
+closing square bracket is required as a member of the class, it should be the
+first data character in the class (after an initial circumflex, if present) or
+escaped with a backslash.
+
+A character class matches a single character in the subject; the character must
+be in the set of characters defined by the class, unless the first character in
+the class is a circumflex, in which case the subject character must not be in
+the set defined by the class. If a circumflex is actually required as a member
+of the class, ensure it is not the first character, or escape it with a
+backslash.
+
+For example, the character class [aeiou] matches any lower case vowel, while
+[^aeiou] matches any character that is not a lower case vowel. Note that a
+circumflex is just a convenient notation for specifying the characters which
+are in the class by enumerating those that are not. It is not an assertion: it
+still consumes a character from the subject string, and fails if the current
+pointer is at the end of the string.
+
+When caseless matching is set, any letters in a class represent both their
+upper case and lower case versions, so for example, a caseless [aeiou] matches
+"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a
+caseful version would.
+
+The newline character is never treated in any special way in character classes,
+whatever the setting of the PCRE_DOTALL or PCRE_MULTILINE options is. A class
+such as [^a] will always match a newline.
+
+The minus (hyphen) character can be used to specify a range of characters in a
+character class. For example, [d-m] matches any letter between d and m,
+inclusive. If a minus character is required in a class, it must be escaped with
+a backslash or appear in a position where it cannot be interpreted as
+indicating a range, typically as the first or last character in the class.
+
+It is not possible to have the literal character "]" as the end character of a
+range. A pattern such as [W-]46] is interpreted as a class of two characters
+("W" and "-") followed by a literal string "46]", so it would match "W46]" or
+"-46]". However, if the "]" is escaped with a backslash it is interpreted as
+the end of range, so [W-\\]46] is interpreted as a single class containing a
+range followed by two separate characters. The octal or hexadecimal
+representation of "]" can also be used to end a range.
+
+Ranges operate in ASCII collating sequence. They can also be used for
+characters specified numerically, for example [\\000-\\037]. If a range that
+includes letters is used when caseless matching is set, it matches the letters
+in either case. For example, [W-c] is equivalent to [][\\^_`wxyzabc], matched
+caselessly, and if character tables for the "fr" locale are in use,
+[\\xc8-\\xcb] matches accented E characters in both cases.
+
+The character types \\d, \\D, \\s, \\S, \\w, and \\W may also appear in a
+character class, and add the characters that they match to the class. For
+example, [\\dABCDEF] matches any hexadecimal digit. A circumflex can
+conveniently be used with the upper case character types to specify a more
+restricted set of characters than the matching lower case type. For example,
+the class [^\\W_] matches any letter or digit, but not underscore.
+
+All non-alphameric characters other than \\, -, ^ (at the start) and the
+terminating ] are non-special in character classes, but it does no harm if they
+are escaped.
+
+
+.SH POSIX CHARACTER CLASSES
+Perl 5.6 (not yet released at the time of writing) is going to support the
+POSIX notation for character classes, which uses names enclosed by [: and :]
+within the enclosing square brackets. PCRE supports this notation. For example,
+
+ [01[:alpha:]%]
+
+matches "0", "1", any alphabetic character, or "%". The supported class names
+are
+
+ alnum letters and digits
+ alpha letters
+ ascii character codes 0 - 127
+ cntrl control characters
+ digit decimal digits (same as \\d)
+ graph printing characters, excluding space
+ lower lower case letters
+ print printing characters, including space
+ punct printing characters, excluding letters and digits
+ space white space (same as \\s)
+ upper upper case letters
+ word "word" characters (same as \\w)
+ xdigit hexadecimal digits
+
+The names "ascii" and "word" are Perl extensions. Another Perl extension is
+negation, which is indicated by a ^ character after the colon. For example,
+
+ [12[:^digit:]]
+
+matches "1", "2", or any non-digit. PCRE (and Perl) also recognize the POSIX
+syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
+supported, and an error is given if they are encountered.
+
+
+.SH VERTICAL BAR
+Vertical bar characters are used to separate alternative patterns. For example,
+the pattern
+
+ gilbert|sullivan
+
+matches either "gilbert" or "sullivan". Any number of alternatives may appear,
+and an empty alternative is permitted (matching the empty string).
+The matching process tries each alternative in turn, from left to right,
+and the first one that succeeds is used. If the alternatives are within a
+subpattern (defined below), "succeeds" means matching the rest of the main
+pattern as well as the alternative in the subpattern.
+
+
+.SH INTERNAL OPTION SETTING
+The settings of PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and PCRE_EXTENDED
+can be changed from within the pattern by a sequence of Perl option letters
+enclosed between "(?" and ")". The option letters are
+
+ i for PCRE_CASELESS
+ m for PCRE_MULTILINE
+ s for PCRE_DOTALL
+ x for PCRE_EXTENDED
+
+For example, (?im) sets caseless, multiline matching. It is also possible to
+unset these options by preceding the letter with a hyphen, and a combined
+setting and unsetting such as (?im-sx), which sets PCRE_CASELESS and
+PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, is also
+permitted. If a letter appears both before and after the hyphen, the option is
+unset.
+
+The scope of these option changes depends on where in the pattern the setting
+occurs. For settings that are outside any subpattern (defined below), the
+effect is the same as if the options were set or unset at the start of
+matching. The following patterns all behave in exactly the same way:
+
+ (?i)abc
+ a(?i)bc
+ ab(?i)c
+ abc(?i)
+
+which in turn is the same as compiling the pattern abc with PCRE_CASELESS set.
+In other words, such "top level" settings apply to the whole pattern (unless
+there are other changes inside subpatterns). If there is more than one setting
+of the same option at top level, the rightmost setting is used.
+
+If an option change occurs inside a subpattern, the effect is different. This
+is a change of behaviour in Perl 5.005. An option change inside a subpattern
+affects only that part of the subpattern that follows it, so
+
+ (a(?i)b)c
+
+matches abc and aBc and no other strings (assuming PCRE_CASELESS is not used).
+By this means, options can be made to have different settings in different
+parts of the pattern. Any changes made in one alternative do carry on
+into subsequent branches within the same subpattern. For example,
+
+ (a(?i)b|c)
+
+matches "ab", "aB", "c", and "C", even though when matching "C" the first
+branch is abandoned before the option setting. This is because the effects of
+option settings happen at compile time. There would be some very weird
+behaviour otherwise.
+
+The PCRE-specific options PCRE_UNGREEDY and PCRE_EXTRA can be changed in the
+same way as the Perl-compatible options by using the characters U and X
+respectively. The (?X) flag setting is special in that it must always occur
+earlier in the pattern than any of the additional features it turns on, even
+when it is at top level. It is best put at the start.
+
+
+.SH SUBPATTERNS
+Subpatterns are delimited by parentheses (round brackets), which can be nested.
+Marking part of a pattern as a subpattern does two things:
+
+1. It localizes a set of alternatives. For example, the pattern
+
+ cat(aract|erpillar|)
+
+matches one of the words "cat", "cataract", or "caterpillar". Without the
+parentheses, it would match "cataract", "erpillar" or the empty string.
+
+2. It sets up the subpattern as a capturing subpattern (as defined above).
+When the whole pattern matches, that portion of the subject string that matched
+the subpattern is passed back to the caller via the \fIovector\fR argument of
+\fBpcre_exec()\fR. Opening parentheses are counted from left to right (starting
+from 1) to obtain the numbers of the capturing subpatterns.
+
+For example, if the string "the red king" is matched against the pattern
+
+ the ((red|white) (king|queen))
+
+the captured substrings are "red king", "red", and "king", and are numbered 1,
+2, and 3, respectively.
+
+The fact that plain parentheses fulfil two functions is not always helpful.
+There are often times when a grouping subpattern is required without a
+capturing requirement. If an opening parenthesis is followed by "?:", the
+subpattern does not do any capturing, and is not counted when computing the
+number of any subsequent capturing subpatterns. For example, if the string "the
+white queen" is matched against the pattern
+
+ the ((?:red|white) (king|queen))
+
+the captured substrings are "white queen" and "queen", and are numbered 1 and
+2. The maximum number of captured substrings is 99, and the maximum number of
+all subpatterns, both capturing and non-capturing, is 200.
+
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing subpattern, the option letters may appear between the "?" and
+the ":". Thus the two patterns
+
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+
+match exactly the same set of strings. Because alternative branches are tried
+from left to right, and options are not reset until the end of the subpattern
+is reached, an option setting in one branch does affect subsequent branches, so
+the above patterns match "SUNDAY" as well as "Saturday".
+
+
+.SH REPETITION
+Repetition is specified by quantifiers, which can follow any of the following
+items:
+
+ a single character, possibly escaped
+ the . metacharacter
+ a character class
+ a back reference (see next section)
+ a parenthesized subpattern (unless it is an assertion - see below)
+
+The general repetition quantifier specifies a minimum and maximum number of
+permitted matches, by giving the two numbers in curly brackets (braces),
+separated by a comma. The numbers must be less than 65536, and the first must
+be less than or equal to the second. For example:
+
+ z{2,4}
+
+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
+character. If the second number is omitted, but the comma is present, there is
+no upper limit; if the second number and the comma are both omitted, the
+quantifier specifies an exact number of required matches. Thus
+
+ [aeiou]{3,}
+
+matches at least 3 successive vowels, but may match many more, while
+
+ \\d{8}
+
+matches exactly 8 digits. An opening curly bracket that appears in a position
+where a quantifier is not allowed, or one that does not match the syntax of a
+quantifier, is taken as a literal character. For example, {,6} is not a
+quantifier, but a literal string of four characters.
+
+The quantifier {0} is permitted, causing the expression to behave as if the
+previous item and the quantifier were not present.
+
+For convenience (and historical compatibility) the three most common
+quantifiers have single-character abbreviations:
+
+ * is equivalent to {0,}
+ + is equivalent to {1,}
+ ? is equivalent to {0,1}
+
+It is possible to construct infinite loops by following a subpattern that can
+match no characters with a quantifier that has no upper limit, for example:
+
+ (a?)*
+
+Earlier versions of Perl and PCRE used to give an error at compile time for
+such patterns. However, because there are cases where this can be useful, such
+patterns are now accepted, but if any repetition of the subpattern does in fact
+match no characters, the loop is forcibly broken.
+
+By default, the quantifiers are "greedy", that is, they match as much as
+possible (up to the maximum number of permitted times), without causing the
+rest of the pattern to fail. The classic example of where this gives problems
+is in trying to match comments in C programs. These appear between the
+sequences /* and */ and within the sequence, individual * and / characters may
+appear. An attempt to match C comments by applying the pattern
+
+ /\\*.*\\*/
+
+to the string
+
+ /* first command */ not comment /* second comment */
+
+fails, because it matches the entire string owing to the greediness of the .*
+item.
+
+However, if a quantifier is followed by a question mark, it ceases to be
+greedy, and instead matches the minimum number of times possible, so the
+pattern
+
+ /\\*.*?\\*/
+
+does the right thing with the C comments. The meaning of the various
+quantifiers is not otherwise changed, just the preferred number of matches.
+Do not confuse this use of question mark with its use as a quantifier in its
+own right. Because it has two uses, it can sometimes appear doubled, as in
+
+ \\d??\\d
+
+which matches one digit by preference, but can match two if that is the only
+way the rest of the pattern matches.
+
+If the PCRE_UNGREEDY option is set (an option which is not available in Perl),
+the quantifiers are not greedy by default, but individual ones can be made
+greedy by following them with a question mark. In other words, it inverts the
+default behaviour.
+
+When a parenthesized subpattern is quantified with a minimum repeat count that
+is greater than 1 or with a limited maximum, more store is required for the
+compiled pattern, in proportion to the size of the minimum or maximum.
+
+If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equivalent
+to Perl's /s) is set, thus allowing the . to match newlines, the pattern is
+implicitly anchored, because whatever follows will be tried against every
+character position in the subject string, so there is no point in retrying the
+overall match at any position after the first. PCRE treats such a pattern as
+though it were preceded by \\A. In cases where it is known that the subject
+string contains no newlines, it is worth setting PCRE_DOTALL when the pattern
+begins with .* in order to obtain this optimization, or alternatively using ^
+to indicate anchoring explicitly.
+
+When a capturing subpattern is repeated, the value captured is the substring
+that matched the final iteration. For example, after
+
+ (tweedle[dume]{3}\\s*)+
+
+has matched "tweedledum tweedledee" the value of the captured substring is
+"tweedledee". However, if there are nested capturing subpatterns, the
+corresponding captured values may have been set in previous iterations. For
+example, after
+
+ /(a|(b))+/
+
+matches "aba" the value of the second captured substring is "b".
+
+
+.SH BACK REFERENCES
+Outside a character class, a backslash followed by a digit greater than 0 (and
+possibly further digits) is a back reference to a capturing subpattern earlier
+(i.e. to its left) in the pattern, provided there have been that many previous
+capturing left parentheses.
+
+However, if the decimal number following the backslash is less than 10, it is
+always taken as a back reference, and causes an error only if there are not
+that many capturing left parentheses in the entire pattern. In other words, the
+parentheses that are referenced need not be to the left of the reference for
+numbers less than 10. See the section entitled "Backslash" above for further
+details of the handling of digits following a backslash.
+
+A back reference matches whatever actually matched the capturing subpattern in
+the current subject string, rather than anything matching the subpattern
+itself. So the pattern
+
+ (sens|respons)e and \\1ibility
+
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If caseful matching is in force at the time of the
+back reference, the case of letters is relevant. For example,
+
+ ((?i)rah)\\s+\\1
+
+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
+capturing subpattern is matched caselessly.
+
+There may be more than one back reference to the same subpattern. If a
+subpattern has not actually been used in a particular match, any back
+references to it always fail. For example, the pattern
+
+ (a|(bc))\\2
+
+always fails if it starts to match "a" rather than "bc". Because there may be
+up to 99 back references, all digits following the backslash are taken
+as part of a potential back reference number. If the pattern continues with a
+digit character, some delimiter must be used to terminate the back reference.
+If the PCRE_EXTENDED option is set, this can be whitespace. Otherwise an empty
+comment can be used.
+
+A back reference that occurs inside the parentheses to which it refers fails
+when the subpattern is first used, so, for example, (a\\1) never matches.
+However, such references can be useful inside repeated subpatterns. For
+example, the pattern
+
+ (a|b\\1)+
+
+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
+the subpattern, the back reference matches the character string corresponding
+to the previous iteration. In order for this to work, the pattern must be such
+that the first iteration does not need to match the back reference. This can be
+done using alternation, as in the example above, or by a quantifier with a
+minimum of zero.
+
+
+.SH ASSERTIONS
+An assertion is a test on the characters following or preceding the current
+matching point that does not actually consume any characters. The simple
+assertions coded as \\b, \\B, \\A, \\Z, \\z, ^ and $ are described above. More
+complicated assertions are coded as subpatterns. There are two kinds: those
+that look ahead of the current position in the subject string, and those that
+look behind it.
+
+An assertion subpattern is matched in the normal way, except that it does not
+cause the current matching position to be changed. Lookahead assertions start
+with (?= for positive assertions and (?! for negative assertions. For example,
+
+ \\w+(?=;)
+
+matches a word followed by a semicolon, but does not include the semicolon in
+the match, and
+
+ foo(?!bar)
+
+matches any occurrence of "foo" that is not followed by "bar". Note that the
+apparently similar pattern
+
+ (?!foo)bar
+
+does not find an occurrence of "bar" that is preceded by something other than
+"foo"; it finds any occurrence of "bar" whatsoever, because the assertion
+(?!foo) is always true when the next three characters are "bar". A
+lookbehind assertion is needed to achieve this effect.
+
+Lookbehind assertions start with (?<= for positive assertions and (?<! for
+negative assertions. For example,
+
+ (?<!foo)bar
+
+does find an occurrence of "bar" that is not preceded by "foo". The contents of
+a lookbehind assertion are restricted such that all the strings it matches must
+have a fixed length. However, if there are several alternatives, they do not
+all have to have the same fixed length. Thus
+
+ (?<=bullock|donkey)
+
+is permitted, but
+
+ (?<!dogs?|cats?)
+
+causes an error at compile time. Branches that match different length strings
+are permitted only at the top level of a lookbehind assertion. This is an
+extension compared with Perl 5.005, which requires all branches to match the
+same length of string. An assertion such as
+
+ (?<=ab(c|de))
+
+is not permitted, because its single top-level branch can match two different
+lengths, but it is acceptable if rewritten to use two top-level branches:
+
+ (?<=abc|abde)
+
+The implementation of lookbehind assertions is, for each alternative, to
+temporarily move the current position back by the fixed width and then try to
+match. If there are insufficient characters before the current position, the
+match is deemed to fail. Lookbehinds in conjunction with once-only subpatterns
+can be particularly useful for matching at the ends of strings; an example is
+given at the end of the section on once-only subpatterns.
+
+Several assertions (of any sort) may occur in succession. For example,
+
+ (?<=\\d{3})(?<!999)foo
+
+matches "foo" preceded by three digits that are not "999". Notice that each of
+the assertions is applied independently at the same point in the subject
+string. First there is a check that the previous three characters are all
+digits, and then there is a check that the same three characters are not "999".
+This pattern does \fInot\fR match "foo" preceded by six characters, the first
+of which are digits and the last three of which are not "999". For example, it
+doesn't match "123abcfoo". A pattern to do that is
+
+ (?<=\\d{3}...)(?<!999)foo
+
+This time the first assertion looks at the preceding six characters, checking
+that the first three are digits, and then the second assertion checks that the
+preceding three characters are not "999".
+
+Assertions can be nested in any combination. For example,
+
+ (?<=(?<!foo)bar)baz
+
+matches an occurrence of "baz" that is preceded by "bar" which in turn is not
+preceded by "foo", while
+
+ (?<=\\d{3}(?!999)...)foo
+
+is another pattern which matches "foo" preceded by three digits and any three
+characters that are not "999".
+
+Assertion subpatterns are not capturing subpatterns, and may not be repeated,
+because it makes no sense to assert the same thing several times. If any kind
+of assertion contains capturing subpatterns within it, these are counted for
+the purposes of numbering the capturing subpatterns in the whole pattern.
+However, substring capturing is carried out only for positive assertions,
+because it does not make sense for negative assertions.
+
+Assertions count towards the maximum of 200 parenthesized subpatterns.
+
+
+.SH ONCE-ONLY SUBPATTERNS
+With both maximizing and minimizing repetition, failure of what follows
+normally causes the repeated item to be re-evaluated to see if a different
+number of repeats allows the rest of the pattern to match. Sometimes it is
+useful to prevent this, either to change the nature of the match, or to cause
+it fail earlier than it otherwise might, when the author of the pattern knows
+there is no point in carrying on.
+
+Consider, for example, the pattern \\d+foo when applied to the subject line
+
+ 123456bar
+
+After matching all 6 digits and then failing to match "foo", the normal
+action of the matcher is to try again with only 5 digits matching the \\d+
+item, and then with 4, and so on, before ultimately failing. Once-only
+subpatterns provide the means for specifying that once a portion of the pattern
+has matched, it is not to be re-evaluated in this way, so the matcher would
+give up immediately on failing to match "foo" the first time. The notation is
+another kind of special parenthesis, starting with (?> as in this example:
+
+ (?>\\d+)bar
+
+This kind of parenthesis "locks up" the part of the pattern it contains once
+it has matched, and a failure further into the pattern is prevented from
+backtracking into it. Backtracking past it to previous items, however, works as
+normal.
+
+An alternative description is that a subpattern of this type matches the string
+of characters that an identical standalone pattern would match, if anchored at
+the current point in the subject string.
+
+Once-only subpatterns are not capturing subpatterns. Simple cases such as the
+above example can be thought of as a maximizing repeat that must swallow
+everything it can. So, while both \\d+ and \\d+? are prepared to adjust the
+number of digits they match in order to make the rest of the pattern match,
+(?>\\d+) can only match an entire sequence of digits.
+
+This construction can of course contain arbitrarily complicated subpatterns,
+and it can be nested.
+
+Once-only subpatterns can be used in conjunction with lookbehind assertions to
+specify efficient matching at the end of the subject string. Consider a simple
+pattern such as
+
+ abcd$
+
+when applied to a long string which does not match. Because matching proceeds
+from left to right, PCRE will look for each "a" in the subject and then see if
+what follows matches the rest of the pattern. If the pattern is specified as
+
+ ^.*abcd$
+
+the initial .* matches the entire string at first, but when this fails (because
+there is no following "a"), it backtracks to match all but the last character,
+then all but the last two characters, and so on. Once again the search for "a"
+covers the entire string, from right to left, so we are no better off. However,
+if the pattern is written as
+
+ ^(?>.*)(?<=abcd)
+
+there can be no backtracking for the .* item; it can match only the entire
+string. The subsequent lookbehind assertion does a single test on the last four
+characters. If it fails, the match fails immediately. For long strings, this
+approach makes a significant difference to the processing time.
+
+When a pattern contains an unlimited repeat inside a subpattern that can itself
+be repeated an unlimited number of times, the use of a once-only subpattern is
+the only way to avoid some failing matches taking a very long time indeed.
+The pattern
+
+ (\\D+|<\\d+>)*[!?]
+
+matches an unlimited number of substrings that either consist of non-digits, or
+digits enclosed in <>, followed by either ! or ?. When it matches, it runs
+quickly. However, if it is applied to
+
+ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+
+it takes a long time before reporting failure. This is because the string can
+be divided between the two repeats in a large number of ways, and all have to
+be tried. (The example used [!?] rather than a single character at the end,
+because both PCRE and Perl have an optimization that allows for fast failure
+when a single character is used. They remember the last single character that
+is required for a match, and fail early if it is not present in the string.)
+If the pattern is changed to
+
+ ((?>\\D+)|<\\d+>)*[!?]
+
+sequences of non-digits cannot be broken, and failure happens quickly.
+
+
+.SH CONDITIONAL SUBPATTERNS
+It is possible to cause the matching process to obey a subpattern
+conditionally or to choose between two alternative subpatterns, depending on
+the result of an assertion, or whether a previous capturing subpattern matched
+or not. The two possible forms of conditional subpattern are
+
+ (?(condition)yes-pattern)
+ (?(condition)yes-pattern|no-pattern)
+
+If the condition is satisfied, the yes-pattern is used; otherwise the
+no-pattern (if present) is used. If there are more than two alternatives in the
+subpattern, a compile-time error occurs.
+
+There are two kinds of condition. If the text between the parentheses consists
+of a sequence of digits, the condition is satisfied if the capturing subpattern
+of that number has previously matched. The number must be greater than zero.
+Consider the following pattern, which contains non-significant white space to
+make it more readable (assume the PCRE_EXTENDED option) and to divide it into
+three parts for ease of discussion:
+
+ ( \\( )? [^()]+ (?(1) \\) )
+
+The first part matches an optional opening parenthesis, and if that
+character is present, sets it as the first captured substring. The second part
+matches one or more characters that are not parentheses. The third part is a
+conditional subpattern that tests whether the first set of parentheses matched
+or not. If they did, that is, if subject started with an opening parenthesis,
+the condition is true, and so the yes-pattern is executed and a closing
+parenthesis is required. Otherwise, since no-pattern is not present, the
+subpattern matches nothing. In other words, this pattern matches a sequence of
+non-parentheses, optionally enclosed in parentheses.
+
+If the condition is not a sequence of digits, it must be an assertion. This may
+be a positive or negative lookahead or lookbehind assertion. Consider this
+pattern, again containing non-significant white space, and with the two
+alternatives on the second line:
+
+ (?(?=[^a-z]*[a-z])
+ \\d{2}-[a-z]{3}-\\d{2} | \\d{2}-\\d{2}-\\d{2} )
+
+The condition is a positive lookahead assertion that matches an optional
+sequence of non-letters followed by a letter. In other words, it tests for the
+presence of at least one letter in the subject. If a letter is found, the
+subject is matched against the first alternative; otherwise it is matched
+against the second. This pattern matches strings in one of the two forms
+dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
+
+
+.SH COMMENTS
+The sequence (?# marks the start of a comment which continues up to the next
+closing parenthesis. Nested parentheses are not permitted. The characters
+that make up a comment play no part in the pattern matching at all.
+
+If the PCRE_EXTENDED option is set, an unescaped # character outside a
+character class introduces a comment that continues up to the next newline
+character in the pattern.
+
+
+.SH RECURSIVE PATTERNS
+Consider the problem of matching a string in parentheses, allowing for
+unlimited nested parentheses. Without the use of recursion, the best that can
+be done is to use a pattern that matches up to some fixed depth of nesting. It
+is not possible to handle an arbitrary nesting depth. Perl 5.6 has provided an
+experimental facility that allows regular expressions to recurse (amongst other
+things). It does this by interpolating Perl code in the expression at run time,
+and the code can refer to the expression itself. A Perl pattern to solve the
+parentheses problem can be created like this:
+
+ $re = qr{\\( (?: (?>[^()]+) | (?p{$re}) )* \\)}x;
+
+The (?p{...}) item interpolates Perl code at run time, and in this case refers
+recursively to the pattern in which it appears. Obviously, PCRE cannot support
+the interpolation of Perl code. Instead, the special item (?R) is provided for
+the specific case of recursion. This PCRE pattern solves the parentheses
+problem (assume the PCRE_EXTENDED option is set so that white space is
+ignored):
+
+ \\( ( (?>[^()]+) | (?R) )* \\)
+
+First it matches an opening parenthesis. Then it matches any number of
+substrings which can either be a sequence of non-parentheses, or a recursive
+match of the pattern itself (i.e. a correctly parenthesized substring). Finally
+there is a closing parenthesis.
+
+This particular example pattern contains nested unlimited repeats, and so the
+use of a once-only subpattern for matching strings of non-parentheses is
+important when applying the pattern to strings that do not match. For example,
+when it is applied to
+
+ (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+
+it yields "no match" quickly. However, if a once-only subpattern is not used,
+the match runs for a very long time indeed because there are so many different
+ways the + and * repeats can carve up the subject, and all have to be tested
+before failure can be reported.
+
+The values set for any capturing subpatterns are those from the outermost level
+of the recursion at which the subpattern value is set. If the pattern above is
+matched against
+
+ (ab(cd)ef)
+
+the value for the capturing parentheses is "ef", which is the last value taken
+on at the top level. If additional parentheses are added, giving
+
+ \\( ( ( (?>[^()]+) | (?R) )* ) \\)
+ ^ ^
+ ^ ^
+the string they capture is "ab(cd)ef", the contents of the top level
+parentheses. If there are more than 15 capturing parentheses in a pattern, PCRE
+has to obtain extra memory to store data during a recursion, which it does by
+using \fBpcre_malloc\fR, freeing it via \fBpcre_free\fR afterwards. If no
+memory can be obtained, it saves data for the first 15 capturing parentheses
+only, as there is no way to give an out-of-memory error from within a
+recursion.
+
+
+.SH PERFORMANCE
+Certain items that may appear in patterns are more efficient than others. It is
+more efficient to use a character class like [aeiou] than a set of alternatives
+such as (a|e|i|o|u). In general, the simplest construction that provides the
+required behaviour is usually the most efficient. Jeffrey Friedl's book
+contains a lot of discussion about optimizing regular expressions for efficient
+performance.
+
+When a pattern begins with .* and the PCRE_DOTALL option is set, the pattern is
+implicitly anchored by PCRE, since it can match only at the start of a subject
+string. However, if PCRE_DOTALL is not set, PCRE cannot make this optimization,
+because the . metacharacter does not then match a newline, and if the subject
+string contains newlines, the pattern may match from the character immediately
+following one of them instead of from the very start. For example, the pattern
+
+ (.*) second
+
+matches the subject "first\\nand second" (where \\n stands for a newline
+character) with the first captured substring being "and". In order to do this,
+PCRE has to retry the match starting after every newline in the subject.
+
+If you are using such a pattern with subject strings that do not contain
+newlines, the best performance is obtained by setting PCRE_DOTALL, or starting
+the pattern with ^.* to indicate explicit anchoring. That saves PCRE from
+having to scan along the subject looking for a newline to restart at.
+
+Beware of patterns that contain nested indefinite repeats. These can take a
+long time to run when applied to a string that does not match. Consider the
+pattern fragment
+
+ (a+)*
+
+This can match "aaaa" in 33 different ways, and this number increases very
+rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4
+times, and for each of those cases other than 0, the + repeats can match
+different numbers of times.) When the remainder of the pattern is such that the
+entire match is going to fail, PCRE has in principle to try every possible
+variation, and this can take an extremely long time.
+
+An optimization catches some of the more simple cases such as
+
+ (a+)*b
+
+where a literal character follows. Before embarking on the standard matching
+procedure, PCRE checks that there is a "b" later in the subject string, and if
+there is not, it fails the match immediately. However, when there is no
+following literal this optimization cannot be used. You can see the difference
+by comparing the behaviour of
+
+ (a+)*\\d
+
+with the pattern above. The former gives a failure almost instantly when
+applied to a whole line of "a" characters, whereas the latter takes an
+appreciable time with strings longer than about 20 characters.
+
+
+.SH UTF-8 SUPPORT
+Starting at release 3.3, PCRE has some support for character strings encoded
+in the UTF-8 format. This is incomplete, and is regarded as experimental. In
+order to use it, you must configure PCRE to include UTF-8 support in the code,
+and, in addition, you must call \fBpcre_compile()\fR with the PCRE_UTF8 option
+flag. When you do this, both the pattern and any subject strings that are
+matched against it are treated as UTF-8 strings instead of just strings of
+bytes, but only in the cases that are mentioned below.
+
+If you compile PCRE with UTF-8 support, but do not use it at run time, the
+library will be a bit bigger, but the additional run time overhead is limited
+to testing the PCRE_UTF8 flag in several places, so should not be very large.
+
+PCRE assumes that the strings it is given contain valid UTF-8 codes. It does
+not diagnose invalid UTF-8 strings. If you pass invalid UTF-8 strings to PCRE,
+the results are undefined.
+
+Running with PCRE_UTF8 set causes these changes in the way PCRE works:
+
+1. In a pattern, the escape sequence \\x{...}, where the contents of the braces
+is a string of hexadecimal digits, is interpreted as a UTF-8 character whose
+code number is the given hexadecimal number, for example: \\x{1234}. This
+inserts from one to six literal bytes into the pattern, using the UTF-8
+encoding. If a non-hexadecimal digit appears between the braces, the item is
+not recognized.
+
+2. The original hexadecimal escape sequence, \\xhh, generates a two-byte UTF-8
+character if its value is greater than 127.
+
+3. Repeat quantifiers are NOT correctly handled if they follow a multibyte
+character. For example, \\x{100}* and \\xc3+ do not work. If you want to
+repeat such characters, you must enclose them in non-capturing parentheses,
+for example (?:\\x{100}), at present.
+
+4. The dot metacharacter matches one UTF-8 character instead of a single byte.
+
+5. Unlike literal UTF-8 characters, the dot metacharacter followed by a
+repeat quantifier does operate correctly on UTF-8 characters instead of
+single bytes.
+
+4. Although the \\x{...} escape is permitted in a character class, characters
+whose values are greater than 255 cannot be included in a class.
+
+5. A class is matched against a UTF-8 character instead of just a single byte,
+but it can match only characters whose values are less than 256. Characters
+with greater values always fail to match a class.
+
+6. Repeated classes work correctly on multiple characters.
+
+7. Classes containing just a single character whose value is greater than 127
+(but less than 256), for example, [\\x80] or [^\\x{93}], do not work because
+these are optimized into single byte matches. In the first case, of course,
+the class brackets are just redundant.
+
+8. Lookbehind assertions move backwards in the subject by a fixed number of
+characters instead of a fixed number of bytes. Simple cases have been tested
+to work correctly, but there may be hidden gotchas herein.
+
+9. The character types such as \\d and \\w do not work correctly with UTF-8
+characters. They continue to test a single byte.
+
+10. Anything not explicitly mentioned here continues to work in bytes rather
+than in characters.
+
+The following UTF-8 features of Perl 5.6 are not implemented:
+
+1. The escape sequence \\C to match a single byte.
+
+2. The use of Unicode tables and properties and escapes \\p, \\P, and \\X.
+
+
+.SH SAMPLE PROGRAM
+The code below is a simple, complete demonstration program, to get you started
+with using PCRE. This code is also supplied in the file \fIpcredemo.c\fR in the
+PCRE distribution.
+
+The program compiles the regular expression that is its first argument, and
+matches it against the subject string in its second argument. No options are
+set, and default character tables are used. If matching succeeds, the program
+outputs the portion of the subject that matched, together with the contents of
+any captured substrings.
+
+On a Unix system that has PCRE installed in \fI/usr/local\fR, you can compile
+the demonstration program using a command like this:
+
+ gcc -o pcredemo pcredemo.c -I/usr/local/include -L/usr/local/lib -lpcre
+
+Then you can run simple tests like this:
+
+ ./pcredemo 'cat|dog' 'the cat sat on the mat'
+
+Note that there is a much more comprehensive test program, called
+\fBpcretest\fR, which supports many more facilities for testing regular
+expressions. The \fBpcredemo\fR program is provided as a simple coding example.
+
+On some operating systems (e.g. Solaris) you may get an error like this when
+you try to run \fBpcredemo\fR:
+
+ ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such file or directory
+
+This is caused by the way shared library support works on those systems. You
+need to add
+
+ -R/usr/local/lib
+
+to the compile command to get round this problem. Here's the code:
+
+ #include <stdio.h>
+ #include <string.h>
+ #include <pcre.h>
+
+ #define OVECCOUNT 30 /* should be a multiple of 3 */
+
+ int main(int argc, char **argv)

+ return 1;
+ }
+

+

+ 0, /* default options */
+ ovector, /* vector for substring information */
+ OVECCOUNT); /* number of elements in the vector */
+
+ /* Matching failed: handle error cases */
+
+ if (rc < 0)
+ {

+ {
+ case PCRE_ERROR_NOMATCH: printf("No match\\n"); break;

+ }
+ return 1;
+ }
+
+ /* Match succeded */
+

+
+ /* The output vector wasn't big enough */
+

+

+<LI><A NAME="SEC3" HREF="#TOC1">DESCRIPTION</A>
+<P>
+The PCRE library is a set of functions that implement regular expression
+pattern matching using the same syntax and semantics as Perl 5, with just a few
+differences (see below). The current implementation corresponds to Perl 5.005,
+with some additional features from later versions. This includes some
+experimental, incomplete support for UTF-8 encoded strings. Details of exactly
+what is and what is not supported are given below.
+</P>
+<P>
+PCRE has its own native API, which is described in this document. There is also
+a set of wrapper functions that correspond to the POSIX regular expression API.
+These are described in the <B>pcreposix</B> documentation.
+</P>
+<P>
+The native API function prototypes are defined in the header file <B>pcre.h</B>,
+and on Unix systems the library itself is called <B>libpcre.a</B>, so can be
+accessed by adding <B>-lpcre</B> to the command for linking an application which
+calls it. The header file defines the macros PCRE_MAJOR and PCRE_MINOR to
+contain the major and minor release numbers for the library. Applications can
+use these to include support for different releases.
+</P>
+<P>
+The functions <B>pcre_compile()</B>, <B>pcre_study()</B>, and <B>pcre_exec()</B>
+are used for compiling and matching regular expressions. A sample program that
+demonstrates the simplest way of using them is given in the file
+<I>pcredemo.c</I>. The last section of this man page describes how to run it.
+</P>
+<P>
+The functions <B>pcre_copy_substring()</B>, <B>pcre_get_substring()</B>, and
+<B>pcre_get_substring_list()</B> are convenience functions for extracting
+captured substrings from a matched subject string; <B>pcre_free_substring()</B>
+and <B>pcre_free_substring_list()</B> are also provided, to free the memory used
+for extracted strings.
+</P>
+<P>
+The function <B>pcre_maketables()</B> is used (optionally) to build a set of
+character tables in the current locale for passing to <B>pcre_compile()</B>.
+</P>
+<P>
+The function <B>pcre_fullinfo()</B> is used to find out information about a
+compiled pattern; <B>pcre_info()</B> is an obsolete version which returns only
+some of the available information, but is retained for backwards compatibility.
+The function <B>pcre_version()</B> returns a pointer to a string containing the
+version of PCRE and its date of release.
+</P>
+<P>
+The global variables <B>pcre_malloc</B> and <B>pcre_free</B> initially contain
+the entry points of the standard <B>malloc()</B> and <B>free()</B> functions
+respectively. PCRE calls the memory management functions via these variables,
+so a calling program can replace them if it wishes to intercept the calls. This
+should be done before calling any PCRE functions.
+</P>
+<LI><A NAME="SEC4" HREF="#TOC1">MULTI-THREADING</A>
+<P>
+The PCRE functions can be used in multi-threading applications, with the
+proviso that the memory management functions pointed to by <B>pcre_malloc</B>
+and <B>pcre_free</B> are shared by all threads.
+</P>
+<P>
+The compiled form of a regular expression is not altered during matching, so
+the same compiled pattern can safely be used by several threads at once.
+</P>
+<LI><A NAME="SEC5" HREF="#TOC1">COMPILING A PATTERN</A>
+<P>
+The function <B>pcre_compile()</B> is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument <I>pattern</I>. A pointer to a single block of memory
+that is obtained via <B>pcre_malloc</B> is returned. This contains the compiled
+code and related data. The <B>pcre</B> type is defined for the returned block;
+this is a typedef for a structure whose contents are not externally defined. It
+is up to the caller to free the memory when it is no longer required.
+</P>
+<P>
+Although the compiled code of a PCRE regex is relocatable, that is, it does not
+depend on memory location, the complete <B>pcre</B> data block is not
+fully relocatable, because it contains a copy of the <I>tableptr</I> argument,
+which is an address (see below).
+</P>
+<P>
+The size of a compiled pattern is roughly proportional to the length of the
+pattern string, except that each character class (other than those containing
+just a single character, negated or not) requires 33 bytes, and repeat
+quantifiers with a minimum greater than one or a bounded maximum cause the
+relevant portions of the compiled pattern to be replicated.
+</P>
+<P>
+The <I>options</I> argument contains independent bits that affect the
+compilation. It should be zero if no options are required. Some of the options,
+in particular, those that are compatible with Perl, can also be set and unset
+from within the pattern (see the detailed description of regular expressions
+below). For these options, the contents of the <I>options</I> argument specifies
+their initial settings at the start of compilation and execution. The
+PCRE_ANCHORED option can be set at the time of matching as well as at compile
+time.
+</P>
+<P>
+If <I>errptr</I> is NULL, <B>pcre_compile()</B> returns NULL immediately.
+Otherwise, if compilation of a pattern fails, <B>pcre_compile()</B> returns
+NULL, and sets the variable pointed to by <I>errptr</I> to point to a textual
+error message. The offset from the start of the pattern to the character where
+the error was discovered is placed in the variable pointed to by
+<I>erroffset</I>, which must not be NULL. If it is, an immediate error is given.
+</P>
+<P>
+If the final argument, <I>tableptr</I>, is NULL, PCRE uses a default set of
+character tables which are built when it is compiled, using the default C
+locale. Otherwise, <I>tableptr</I> must be the result of a call to
+<B>pcre_maketables()</B>. See the section on locale support below.
+</P>
+<P>
+This code fragment shows a typical straightforward call to <B>pcre_compile()</B>:
+</P>
+<P>
+<PRE>
+ pcre *re;
+ const char *error;
+ int erroffset;
+ re = pcre_compile(
+ "^A.*Z", /* the pattern */
+ 0, /* default options */
+ &error, /* for error message */
+ &erroffset, /* for error offset */
+ NULL); /* use default character tables */
+</PRE>
+</P>
+<P>
+The following option bits are defined in the header file:
+</P>
+<P>
+<PRE>
+ PCRE_ANCHORED
+</PRE>
+</P>
+<P>
+If this bit is set, the pattern is forced to be "anchored", that is, it is
+constrained to match only at the start of the string which is being searched
+(the "subject string"). This effect can also be achieved by appropriate
+constructs in the pattern itself, which is the only way to do it in Perl.
+</P>
+<P>
+<PRE>
+ PCRE_CASELESS
+</PRE>
+</P>
+<P>
+If this bit is set, letters in the pattern match both upper and lower case
+letters. It is equivalent to Perl's /i option.
+</P>
+<P>
+<PRE>
+ PCRE_DOLLAR_ENDONLY
+</PRE>
+</P>
+<P>
+If this bit is set, a dollar metacharacter in the pattern matches only at the
+end of the subject string. Without this option, a dollar also matches
+immediately before the final character if it is a newline (but not before any
+other newlines). The PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is
+set. There is no equivalent to this option in Perl.
+</P>
+<P>
+<PRE>
+ PCRE_DOTALL
+</PRE>
+</P>
+<P>
+If this bit is set, a dot metacharater in the pattern matches all characters,
+including newlines. Without it, newlines are excluded. This option is
+equivalent to Perl's /s option. A negative class such as [^a] always matches a
+newline character, independent of the setting of this option.
+</P>
+<P>
+<PRE>
+ PCRE_EXTENDED
+</PRE>
+</P>
+<P>
+If this bit is set, whitespace data characters in the pattern are totally
+ignored except when escaped or inside a character class, and characters between
+an unescaped # outside a character class and the next newline character,
+inclusive, are also ignored. This is equivalent to Perl's /x option, and makes
+it possible to include comments inside complicated patterns. Note, however,
+that this applies only to data characters. Whitespace characters may never
+appear within special character sequences in a pattern, for example within the
+sequence (?( which introduces a conditional subpattern.
+</P>
+<P>
+<PRE>
+ PCRE_EXTRA
+</PRE>
+</P>
+<P>
+This option was invented in order to turn on additional functionality of PCRE
+that is incompatible with Perl, but it is currently of very little use. When
+set, any backslash in a pattern that is followed by a letter that has no
+special meaning causes an error, thus reserving these combinations for future
+expansion. By default, as in Perl, a backslash followed by a letter with no
+special meaning is treated as a literal. There are at present no other features
+controlled by this option. It can also be set by a (?X) option setting within a
+pattern.
+</P>
+<P>
+<PRE>
+ PCRE_MULTILINE
+</PRE>
+</P>
+<P>
+By default, PCRE treats the subject string as consisting of a single "line" of
+characters (even if it actually contains several newlines). The "start of line"
+metacharacter (^) matches only at the start of the string, while the "end of
+line" metacharacter ($) matches only at the end of the string, or before a
+terminating newline (unless PCRE_DOLLAR_ENDONLY is set). This is the same as
+Perl.
+</P>
+<P>
+When PCRE_MULTILINE it is set, the "start of line" and "end of line" constructs
+match immediately following or immediately before any newline in the subject
+string, respectively, as well as at the very start and end. This is equivalent
+to Perl's /m option. If there are no "\n" characters in a subject string, or
+no occurrences of ^ or $ in a pattern, setting PCRE_MULTILINE has no
+effect.
+</P>
+<P>
+<PRE>
+ PCRE_UNGREEDY
+</PRE>
+</P>
+<P>
+This option inverts the "greediness" of the quantifiers so that they are not
+greedy by default, but become greedy if followed by "?". It is not compatible
+with Perl. It can also be set by a (?U) option setting within the pattern.
+</P>
+<P>
+<PRE>
+ PCRE_UTF8
+</PRE>
+</P>
+<P>
+This option causes PCRE to regard both the pattern and the subject as strings
+of UTF-8 characters instead of just byte strings. However, it is available only
+if PCRE has been built to include UTF-8 support. If not, the use of this option
+provokes an error. Support for UTF-8 is new, experimental, and incomplete.
+Details of exactly what it entails are given below.
+</P>
+<LI><A NAME="SEC6" HREF="#TOC1">STUDYING A PATTERN</A>
+<P>
+When a pattern is going to be used several times, it is worth spending more
+time analyzing it in order to speed up the time taken for matching. The
+function <B>pcre_study()</B> takes a pointer to a compiled pattern as its first
+argument, and returns a pointer to a <B>pcre_extra</B> block (another typedef
+for a structure with hidden contents) containing additional information about
+the pattern; this can be passed to <B>pcre_exec()</B>. If no additional
+information is available, NULL is returned.
+</P>
+<P>
+The second argument contains option bits. At present, no options are defined
+for <B>pcre_study()</B>, and this argument should always be zero.
+</P>
+<P>
+The third argument for <B>pcre_study()</B> is a pointer to an error message. If
+studying succeeds (even if no data is returned), the variable it points to is
+set to NULL. Otherwise it points to a textual error message.
+</P>
+<P>
+This is a typical call to <B>pcre_study</B>():
+</P>
+<P>
+<PRE>
+ pcre_extra *pe;
+ pe = pcre_study(
+ re, /* result of pcre_compile() */
+ 0, /* no options exist */
+ &error); /* set to NULL or points to a message */
+</PRE>
+</P>
+<P>
+At present, studying a pattern is useful only for non-anchored patterns that do
+not have a single fixed starting character. A bitmap of possible starting
+characters is created.
+</P>
+<LI><A NAME="SEC7" HREF="#TOC1">LOCALE SUPPORT</A>
+<P>
+PCRE handles caseless matching, and determines whether characters are letters,
+digits, or whatever, by reference to a set of tables. The library contains a
+default set of tables which is created in the default C locale when PCRE is
+compiled. This is used when the final argument of <B>pcre_compile()</B> is NULL,
+and is sufficient for many applications.
+</P>
+<P>
+An alternative set of tables can, however, be supplied. Such tables are built
+by calling the <B>pcre_maketables()</B> function, which has no arguments, in the
+relevant locale. The result can then be passed to <B>pcre_compile()</B> as often
+as necessary. For example, to build and use tables that are appropriate for the
+French locale (where accented characters with codes greater than 128 are
+treated as letters), the following code could be used:
+</P>
+<P>
+<PRE>
+ setlocale(LC_CTYPE, "fr");
+ tables = pcre_maketables();
+ re = pcre_compile(..., tables);
+</PRE>
+</P>
+<P>
+The tables are built in memory that is obtained via <B>pcre_malloc</B>. The
+pointer that is passed to <B>pcre_compile</B> is saved with the compiled
+pattern, and the same tables are used via this pointer by <B>pcre_study()</B>
+and <B>pcre_exec()</B>. Thus for any single pattern, compilation, studying and
+matching all happen in the same locale, but different patterns can be compiled
+in different locales. It is the caller's responsibility to ensure that the
+memory containing the tables remains available for as long as it is needed.
+</P>
+<LI><A NAME="SEC8" HREF="#TOC1">INFORMATION ABOUT A PATTERN</A>
+<P>
+The <B>pcre_fullinfo()</B> function returns information about a compiled
+pattern. It replaces the obsolete <B>pcre_info()</B> function, which is
+nevertheless retained for backwards compability (and is documented below).
+</P>
+<P>
+The first argument for <B>pcre_fullinfo()</B> is a pointer to the compiled
+pattern. The second argument is the result of <B>pcre_study()</B>, or NULL if
+the pattern was not studied. The third argument specifies which piece of
+information is required, while the fourth argument is a pointer to a variable
+to receive the data. The yield of the function is zero for success, or one of

+</P>
+<P>
+<PRE>
+ PCRE_ERROR_NULL the argument <I>code</I> was NULL

+ PCRE_ERROR_BADMAGIC the "magic number" was not found

+<P>
+<PRE>
+ PCRE_INFO_OPTIONS
+</PRE>
+</P>
+<P>
+Return a copy of the options with which the pattern was compiled. The fourth
+argument should point to an <B>unsigned long int</B> variable. These option bits

+</P>
+<P>
+<PRE>
+ PCRE_INFO_FIRSTCHAR
+</PRE>
+</P>
+<P>
+Return information about the first character of any matched string, for a

+such as (cat|cow|coyote), it is returned in the integer pointed to by
+<I>where</I>. Otherwise, if either
+</P>
+<P>
+(a) the pattern was compiled with the PCRE_MULTILINE option, and every branch

+<P>
+<PRE>
+ PCRE_INFO_FIRSTTABLE

+</P>
+<P>
+If the pattern was studied, and this resulted in the construction of a 256-bit

+<P>
+The first character of the string is not the beginning of a line, so the

+PCRE_MULTILINE (at compile time) causes circumflex never to match.
+</P>
+<P>
+<PRE>
+ PCRE_NOTEOL
+</PRE>
+</P>
+<P>
+The end of the string is not the end of a line, so the dollar metacharacter
+should not match it nor (except in multiline mode) a newline immediately before
+it. Setting this without PCRE_MULTILINE (at compile time) causes dollar never
+to match.
+</P>
+<P>
+<PRE>
+ PCRE_NOTEMPTY
+</PRE>
+</P>
+<P>
+An empty string is not considered to be a valid match if this option is set. If
+there are alternatives in the pattern, they are tried. If all the alternatives
+match the empty string, the entire match fails. For example, if the pattern
+</P>
+<P>
+<PRE>
+ a?b?
+</PRE>
+</P>
+<P>
+is applied to a string not beginning with "a" or "b", it matches the empty
+string at the start of the subject. With PCRE_NOTEMPTY set, this match is not
+valid, so PCRE searches further into the string for occurrences of "a" or "b".
+</P>
+<P>
+Perl has no direct equivalent of PCRE_NOTEMPTY, but it does make a special case
+of a pattern match of the empty string within its <B>split()</B> function, and
+when using the /g modifier. It is possible to emulate Perl's behaviour after
+matching a null string by first trying the match again at the same offset with
+PCRE_NOTEMPTY set, and then if that fails by advancing the starting offset (see
+below) and trying an ordinary match again.
+</P>
+<P>
+The subject string is passed as a pointer in <I>subject</I>, a length in
+<I>length</I>, and a starting offset in <I>startoffset</I>. Unlike the pattern
+string, the subject may contain binary zero characters. When the starting
+offset is zero, the search for a match starts at the beginning of the subject,
+and this is by far the most common case.
+</P>
+<P>
+A non-zero starting offset is useful when searching for another match in the
+same subject by calling <B>pcre_exec()</B> again after a previous success.
+Setting <I>startoffset</I> differs from just passing over a shortened string and
+setting PCRE_NOTBOL in the case of a pattern that begins with any kind of
+lookbehind. For example, consider the pattern
+</P>
+<P>
+<PRE>
+ \Biss\B
+</PRE>
+</P>
+<P>
+which finds occurrences of "iss" in the middle of words. (\B matches only if
+the current position in the subject is not a word boundary.) When applied to
+the string "Mississipi" the first call to <B>pcre_exec()</B> finds the first
+occurrence. If <B>pcre_exec()</B> is called again with just the remainder of the
+subject, namely "issipi", it does not match, because \B is always false at the
+start of the subject, which is deemed to be a word boundary. However, if
+<B>pcre_exec()</B> is passed the entire string again, but with <I>startoffset</I>
+set to 4, it finds the second occurrence of "iss" because it is able to look
+behind the starting point to discover that it is preceded by a letter.
+</P>
+<P>
+If a non-zero starting offset is passed when the pattern is anchored, one
+attempt to match at the given offset is tried. This can only succeed if the
+pattern does not require the match to be at the start of the subject.
+</P>
+<P>
+In general, a pattern matches a certain portion of the subject, and in
+addition, further substrings from the subject may be picked out by parts of the
+pattern. Following the usage in Jeffrey Friedl's book, this is called
+"capturing" in what follows, and the phrase "capturing subpattern" is used for
+a fragment of a pattern that picks out a substring. PCRE supports several other
+kinds of parenthesized subpattern that do not cause substrings to be captured.
+</P>
+<P>
+Captured substrings are returned to the caller via a vector of integer offsets
+whose address is passed in <I>ovector</I>. The number of elements in the vector
+is passed in <I>ovecsize</I>. The first two-thirds of the vector is used to pass
+back captured substrings, each substring using a pair of integers. The
+remaining third of the vector is used as workspace by <B>pcre_exec()</B> while
+matching capturing subpatterns, and is not available for passing back
+information. The length passed in <I>ovecsize</I> should always be a multiple of
+three. If it is not, it is rounded down.
+</P>
+<P>
+When a match has been successful, information about captured substrings is
+returned in pairs of integers, starting at the beginning of <I>ovector</I>, and
+continuing up to two-thirds of its length at the most. The first element of a
+pair is set to the offset of the first character in a substring, and the second
+is set to the offset of the first character after the end of a substring. The
+first pair, <I>ovector[0]</I> and <I>ovector[1]</I>, identify the portion of the
+subject string matched by the entire pattern. The next pair is used for the
+first capturing subpattern, and so on. The value returned by <B>pcre_exec()</B>
+is the number of pairs that have been set. If there are no capturing
+subpatterns, the return value from a successful match is 1, indicating that
+just the first pair of offsets has been set.
+</P>
+<P>
+Some convenience functions are provided for extracting the captured substrings
+as separate strings. These are described in the following section.
+</P>
+<P>
+It is possible for an capturing subpattern number <I>n+1</I> to match some
+part of the subject when subpattern <I>n</I> has not been used at all. For
+example, if the string "abc" is matched against the pattern (a|(z))(bc)
+subpatterns 1 and 3 are matched, but 2 is not. When this happens, both offset
+values corresponding to the unused subpattern are set to -1.
+</P>
+<P>
+If a capturing subpattern is matched repeatedly, it is the last portion of the
+string that it matched that gets returned.
+</P>
+<P>
+If the vector is too small to hold all the captured substrings, it is used as
+far as possible (up to two-thirds of its length), and the function returns a
+value of zero. In particular, if the substring offsets are not of interest,
+<B>pcre_exec()</B> may be called with <I>ovector</I> passed as NULL and
+<I>ovecsize</I> as zero. However, if the pattern contains back references and
+the <I>ovector</I> isn't big enough to remember the related substrings, PCRE has
+to get additional memory for use during matching. Thus it is usually advisable
+to supply an <I>ovector</I>.
+</P>
+<P>
+Note that <B>pcre_info()</B> can be used to find out how many capturing
+subpatterns there are in a compiled pattern. The smallest size for
+<I>ovector</I> that will allow for <I>n</I> captured substrings in addition to
+the offsets of the substring matched by the whole pattern is (<I>n</I>+1)*3.
+</P>
+<P>
+If <B>pcre_exec()</B> fails, it returns a negative number. The following are
+defined in the header file:

+<LI><A NAME="SEC10" HREF="#TOC1">EXTRACTING CAPTURED SUBSTRINGS</A>
+<P>
+Captured substrings can be accessed directly by using the offsets returned by

+<B>pcre_copy_substring()</B>, <B>pcre_get_substring()</B>, and
+<B>pcre_get_substring_list()</B> are provided for extracting captured substrings
+as new, separate, zero-terminated strings. A substring that contains a binary
+zero is correctly extracted and has a further zero added on the end, but the
+result does not, of course, function as a C string.
+</P>
+<P>
+The first three arguments are the same for all three functions: <I>subject</I>
+is the subject string which has just been successfully matched, <I>ovector</I>
+is a pointer to the vector of integer offsets that was passed to
+<B>pcre_exec()</B>, and <I>stringcount</I> is the number of substrings that
+were captured by the match, including the substring that matched the entire
+regular expression. This is the value returned by <B>pcre_exec</B> if it
+is greater than zero. If <B>pcre_exec()</B> returned zero, indicating that it
+ran out of space in <I>ovector</I>, the value passed as <I>stringcount</I> should

+string. This can be distinguished from a genuine zero-length substring by

+provided.
+</P>
+<LI><A NAME="SEC11" HREF="#TOC1">LIMITATIONS</A>
+<P>
+There are some size limitations in PCRE but it is hoped that they will never in
+practice be relevant.
+The maximum length of a compiled pattern is 65539 (sic) bytes.
+All values in repeating quantifiers must be less than 65536.
+There maximum number of capturing subpatterns is 65535.
+There is no limit to the number of non-capturing subpatterns, but the maximum
+depth of nesting of all kinds of parenthesized subpattern, including capturing
+subpatterns, assertions, and other types of subpattern, is 200.
+</P>
+<P>
+The maximum length of a subject string is the largest positive number that an
+integer variable can hold. However, PCRE uses recursion to handle subpatterns
+and indefinite repetition. This means that the available stack space may limit
+the size of a subject string that can be processed by certain patterns.
+</P>
+<LI><A NAME="SEC12" HREF="#TOC1">DIFFERENCES FROM PERL</A>
+<P>
+The differences described here are with respect to Perl 5.005.
+</P>
+<P>
+1. By default, a whitespace character is any character that the C library
+function <B>isspace()</B> recognizes, though it is possible to compile PCRE with
+alternative character type tables. Normally <B>isspace()</B> matches space,
+formfeed, newline, carriage return, horizontal tab, and vertical tab. Perl 5
+no longer includes vertical tab in its set of whitespace characters. The \v
+escape that was in the Perl documentation for a long time was never in fact
+recognized. However, the character itself was treated as whitespace at least
+up to 5.002. In 5.004 and 5.005 it does not match \s.
+</P>
+<P>
+2. PCRE does not allow repeat quantifiers on lookahead assertions. Perl permits
+them, but they do not mean what you might think. For example, (?!a){3} does
+not assert that the next three characters are not "a". It just asserts that the
+next character is not "a" three times.
+</P>
+<P>
+3. Capturing subpatterns that occur inside negative lookahead assertions are
+counted, but their entries in the offsets vector are never set. Perl sets its
+numerical variables from any such patterns that are matched before the
+assertion fails to match something (thereby succeeding), but only if the
+negative lookahead assertion contains just one branch.
+</P>
+<P>
+4. Though binary zero characters are supported in the subject string, they are
+not allowed in a pattern string because it is passed as a normal C string,
+terminated by zero. The escape sequence "\0" can be used in the pattern to
+represent a binary zero.
+</P>
+<P>
+5. The following Perl escape sequences are not supported: \l, \u, \L, \U,
+\E, \Q. In fact these are implemented by Perl's general string-handling and
+are not part of its pattern matching engine.
+</P>
+<P>
+6. The Perl \G assertion is not supported as it is not relevant to single
+pattern matches.
+</P>
+<P>
+7. Fairly obviously, PCRE does not support the (?{code}) and (?p{code})
+constructions. However, there is some experimental support for recursive
+patterns using the non-Perl item (?R).
+</P>
+<P>
+8. There are at the time of writing some oddities in Perl 5.005_02 concerned
+with the settings of captured strings when part of a pattern is repeated. For
+example, matching "aba" against the pattern /^(a(b)?)+$/ sets $2 to the value
+"b", but matching "aabbaa" against /^(aa(bb)?)+$/ leaves $2 unset. However, if
+the pattern is changed to /^(aa(b(b))?)+$/ then $2 (and $3) are set.
+</P>
+<P>
+In Perl 5.004 $2 is set in both cases, and that is also true of PCRE. If in the
+future Perl changes to a consistent state that is different, PCRE may change to
+follow.
+</P>
+<P>
+9. Another as yet unresolved discrepancy is that in Perl 5.005_02 the pattern
+/^(a)?(?(1)a|b)+$/ matches the string "a", whereas in PCRE it does not.
+However, in both Perl and PCRE /^(a)?a/ matched against "a" leaves $1 unset.
+</P>
+<P>
+10. PCRE provides some extensions to the Perl regular expression facilities:
+</P>
+<P>
+(a) Although lookbehind assertions must match fixed length strings, each
+alternative branch of a lookbehind assertion can match a different length of
+string. Perl 5.005 requires them all to have the same length.
+</P>
+<P>
+(b) If PCRE_DOLLAR_ENDONLY is set and PCRE_MULTILINE is not set, the $ meta-
+character matches only at the very end of the string.
+</P>
+<P>
+(c) If PCRE_EXTRA is set, a backslash followed by a letter with no special
+meaning is faulted.
+</P>
+<P>
+(d) If PCRE_UNGREEDY is set, the greediness of the repetition quantifiers is
+inverted, that is, by default they are not greedy, but if followed by a
+question mark they are.
+</P>
+<P>
+(e) PCRE_ANCHORED can be used to force a pattern to be tried only at the start
+of the subject.
+</P>
+<P>
+(f) The PCRE_NOTBOL, PCRE_NOTEOL, and PCRE_NOTEMPTY options for
+<B>pcre_exec()</B> have no Perl equivalents.
+</P>
+<P>
+(g) The (?R) construct allows for recursive pattern matching (Perl 5.6 can do
+this using the (?p{code}) construct, which PCRE cannot of course support.)
+</P>
+<LI><A NAME="SEC13" HREF="#TOC1">REGULAR EXPRESSION DETAILS</A>
+<P>
+The syntax and semantics of the regular expressions supported by PCRE are
+described below. Regular expressions are also described in the Perl
+documentation and in a number of other books, some of which have copious
+examples. Jeffrey Friedl's "Mastering Regular Expressions", published by
+O'Reilly (ISBN 1-56592-257), covers them in great detail.
+</P>
+<P>
+The description here is intended as reference documentation. The basic
+operation of PCRE is on strings of bytes. However, there is the beginnings of
+some support for UTF-8 character strings. To use this support you must
+configure PCRE to include it, and then call <B>pcre_compile()</B> with the
+PCRE_UTF8 option. How this affects the pattern matching is described in the
+final section of this document.
+</P>
+<P>
+A regular expression is a pattern that is matched against a subject string from
+left to right. Most characters stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the pattern
+</P>
+<P>
+<PRE>
+ The quick brown fox
+</PRE>
+</P>
+<P>
+matches a portion of a subject string that is identical to itself. The power of
+regular expressions comes from the ability to include alternatives and
+repetitions in the pattern. These are encoded in the pattern by the use of
+<I>meta-characters</I>, which do not stand for themselves but instead are
+interpreted in some special way.
+</P>
+<P>
+There are two different sets of meta-characters: those that are recognized
+anywhere in the pattern except within square brackets, and those that are
+recognized in square brackets. Outside square brackets, the meta-characters are
+as follows:
+</P>
+<P>
+<PRE>
+ \ general escape character with several uses
+ ^ assert start of subject (or line, in multiline mode)
+ $ assert end of subject (or line, in multiline mode)
+ . match any character except newline (by default)
+ [ start character class definition
+ | start of alternative branch
+ ( start subpattern
+ ) end subpattern
+ ? extends the meaning of (
+ also 0 or 1 quantifier
+ also quantifier minimizer
+ * 0 or more quantifier
+ + 1 or more quantifier
+ { start min/max quantifier
+</PRE>
+</P>
+<P>
+Part of a pattern that is in square brackets is called a "character class". In
+a character class the only meta-characters are:
+</P>
+<P>
+<PRE>
+ \ general escape character
+ ^ negate the class, but only if the first character
+ - indicates character range
+ ] terminates the character class
+</PRE>
+</P>
+<P>
+The following sections describe the use of each of the meta-characters.
+</P>
+<LI><A NAME="SEC14" HREF="#TOC1">BACKSLASH</A>
+<P>
+The backslash character has several uses. Firstly, if it is followed by a
+non-alphameric character, it takes away any special meaning that character may
+have. This use of backslash as an escape character applies both inside and
+outside character classes.
+</P>
+<P>
+For example, if you want to match a "*" character, you write "\*" in the
+pattern. This applies whether or not the following character would otherwise be
+interpreted as a meta-character, so it is always safe to precede a
+non-alphameric with "\" to specify that it stands for itself. In particular,
+if you want to match a backslash, you write "\\".
+</P>
+<P>
+If a pattern is compiled with the PCRE_EXTENDED option, whitespace in the
+pattern (other than in a character class) and characters between a "#" outside
+a character class and the next newline character are ignored. An escaping
+backslash can be used to include a whitespace or "#" character as part of the
+pattern.
+</P>
+<P>
+A second use of backslash provides a way of encoding non-printing characters
+in patterns in a visible manner. There is no restriction on the appearance of
+non-printing characters, apart from the binary zero that terminates a pattern,
+but when a pattern is being prepared by text editing, it is usually easier to
+use one of the following escape sequences than the binary character it
+represents:
+</P>
+<P>
+<PRE>
+ \a alarm, that is, the BEL character (hex 07)
+ \cx "control-x", where x is any character
+ \e escape (hex 1B)
+ \f formfeed (hex 0C)
+ \n newline (hex 0A)
+ \r carriage return (hex 0D)
+ \t tab (hex 09)
+ \xhh character with hex code hh
+ \ddd character with octal code ddd, or backreference
+</PRE>
+</P>
+<P>
+The precise effect of "\cx" is as follows: if "x" is a lower case letter, it
+is converted to upper case. Then bit 6 of the character (hex 40) is inverted.
+Thus "\cz" becomes hex 1A, but "\c{" becomes hex 3B, while "\c;" becomes hex
+7B.
+</P>
+<P>
+After "\x", up to two hexadecimal digits are read (letters can be in upper or
+lower case).
+</P>
+<P>
+After "\0" up to two further octal digits are read. In both cases, if there
+are fewer than two digits, just those that are present are used. Thus the
+sequence "\0\x\07" specifies two binary zeros followed by a BEL character.
+Make sure you supply two digits after the initial zero if the character that
+follows is itself an octal digit.
+</P>
+<P>
+The handling of a backslash followed by a digit other than 0 is complicated.
+Outside a character class, PCRE reads it and any following digits as a decimal
+number. If the number is less than 10, or if there have been at least that many
+previous capturing left parentheses in the expression, the entire sequence is
+taken as a <I>back reference</I>. A description of how this works is given
+later, following the discussion of parenthesized subpatterns.
+</P>
+<P>
+Inside a character class, or if the decimal number is greater than 9 and there
+have not been that many capturing subpatterns, PCRE re-reads up to three octal
+digits following the backslash, and generates a single byte from the least
+significant 8 bits of the value. Any subsequent digits stand for themselves.
+For example:
+</P>
+<P>
+<PRE>
+ \040 is another way of writing a space
+ \40 is the same, provided there are fewer than 40
+ previous capturing subpatterns
+ \7 is always a back reference
+ \11 might be a back reference, or another way of
+ writing a tab
+ \011 is always a tab
+ \0113 is a tab followed by the character "3"
+ \113 is the character with octal code 113 (since there
+ can be no more than 99 back references)
+ \377 is a byte consisting entirely of 1 bits
+ \81 is either a back reference, or a binary zero
+ followed by the two characters "8" and "1"
+</PRE>
+</P>
+<P>
+Note that octal values of 100 or greater must not be introduced by a leading
+zero, because no more than three octal digits are ever read.
+</P>
+<P>
+All the sequences that define a single byte value can be used both inside and
+outside character classes. In addition, inside a character class, the sequence
+"\b" is interpreted as the backspace character (hex 08). Outside a character
+class it has a different meaning (see below).
+</P>
+<P>
+The third use of backslash is for specifying generic character types:
+</P>
+<P>
+<PRE>
+ \d any decimal digit
+ \D any character that is not a decimal digit
+ \s any whitespace character
+ \S any character that is not a whitespace character
+ \w any "word" character
+ \W any "non-word" character
+</PRE>
+</P>
+<P>
+Each pair of escape sequences partitions the complete set of characters into
+two disjoint sets. Any given character matches one, and only one, of each pair.
+</P>
+<P>
+A "word" character is any letter or digit or the underscore character, that is,
+any character which can be part of a Perl "word". The definition of letters and
+digits is controlled by PCRE's character tables, and may vary if locale-
+specific matching is taking place (see "Locale support" above). For example, in
+the "fr" (French) locale, some character codes greater than 128 are used for
+accented letters, and these are matched by \w.
+</P>
+<P>
+These character type sequences can appear both inside and outside character
+classes. They each match one character of the appropriate type. If the current
+matching point is at the end of the subject string, all of them fail, since
+there is no character to match.
+</P>
+<P>
+The fourth use of backslash is for certain simple assertions. An assertion
+specifies a condition that has to be met at a particular point in a match,
+without consuming any characters from the subject string. The use of
+subpatterns for more complicated assertions is described below. The backslashed
+assertions are
+</P>
+<P>
+<PRE>
+ \b word boundary
+ \B not a word boundary
+ \A start of subject (independent of multiline mode)
+ \Z end of subject or newline at end (independent of multiline mode)
+ \z end of subject (independent of multiline mode)
+</PRE>
+</P>
+<P>
+These assertions may not appear in character classes (but note that "\b" has a
+different meaning, namely the backspace character, inside a character class).
+</P>
+<P>
+A word boundary is a position in the subject string where the current character
+and the previous character do not both match \w or \W (i.e. one matches
+\w and the other matches \W), or the start or end of the string if the
+first or last character matches \w, respectively.
+</P>
+<P>
+The \A, \Z, and \z assertions differ from the traditional circumflex and
+dollar (described below) in that they only ever match at the very start and end
+of the subject string, whatever options are set. They are not affected by the
+PCRE_NOTBOL or PCRE_NOTEOL options. If the <I>startoffset</I> argument of
+<B>pcre_exec()</B> is non-zero, \A can never match. The difference between \Z
+and \z is that \Z matches before a newline that is the last character of the
+string as well as at the end of the string, whereas \z matches only at the
+end.
+</P>
+<LI><A NAME="SEC15" HREF="#TOC1">CIRCUMFLEX AND DOLLAR</A>
+<P>
+Outside a character class, in the default matching mode, the circumflex
+character is an assertion which is true only if the current matching point is
+at the start of the subject string. If the <I>startoffset</I> argument of
+<B>pcre_exec()</B> is non-zero, circumflex can never match. Inside a character
+class, circumflex has an entirely different meaning (see below).
+</P>
+<P>
+Circumflex need not be the first character of the pattern if a number of
+alternatives are involved, but it should be the first thing in each alternative
+in which it appears if the pattern is ever to match that branch. If all
+possible alternatives start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is said to be an
+"anchored" pattern. (There are also other constructs that can cause a pattern
+to be anchored.)
+</P>
+<P>
+A dollar character is an assertion which is true only if the current matching
+point is at the end of the subject string, or immediately before a newline
+character that is the last character in the string (by default). Dollar need
+not be the last character of the pattern if a number of alternatives are
+involved, but it should be the last item in any branch in which it appears.
+Dollar has no special meaning in a character class.
+</P>
+<P>
+The meaning of dollar can be changed so that it matches only at the very end of
+the string, by setting the PCRE_DOLLAR_ENDONLY option at compile or matching
+time. This does not affect the \Z assertion.
+</P>
+<P>
+The meanings of the circumflex and dollar characters are changed if the
+PCRE_MULTILINE option is set. When this is the case, they match immediately
+after and immediately before an internal "\n" character, respectively, in
+addition to matching at the start and end of the subject string. For example,
+the pattern /^abc$/ matches the subject string "def\nabc" in multiline mode,
+but not otherwise. Consequently, patterns that are anchored in single line mode
+because all branches start with "^" are not anchored in multiline mode, and a
+match for circumflex is possible when the <I>startoffset</I> argument of
+<B>pcre_exec()</B> is non-zero. The PCRE_DOLLAR_ENDONLY option is ignored if
+PCRE_MULTILINE is set.
+</P>
+<P>
+Note that the sequences \A, \Z, and \z can be used to match the start and
+end of the subject in both modes, and if all branches of a pattern start with
+\A it is always anchored, whether PCRE_MULTILINE is set or not.
+</P>
+<LI><A NAME="SEC16" HREF="#TOC1">FULL STOP (PERIOD, DOT)</A>
+<P>
+Outside a character class, a dot in the pattern matches any one character in
+the subject, including a non-printing character, but not (by default) newline.
+If the PCRE_DOTALL option is set, dots match newlines as well. The handling of
+dot is entirely independent of the handling of circumflex and dollar, the only
+relationship being that they both involve newline characters. Dot has no
+special meaning in a character class.
+</P>
+<LI><A NAME="SEC17" HREF="#TOC1">SQUARE BRACKETS</A>
+<P>
+An opening square bracket introduces a character class, terminated by a closing
+square bracket. A closing square bracket on its own is not special. If a
+closing square bracket is required as a member of the class, it should be the
+first data character in the class (after an initial circumflex, if present) or
+escaped with a backslash.
+</P>
+<P>
+A character class matches a single character in the subject; the character must
+be in the set of characters defined by the class, unless the first character in
+the class is a circumflex, in which case the subject character must not be in
+the set defined by the class. If a circumflex is actually required as a member
+of the class, ensure it is not the first character, or escape it with a
+backslash.
+</P>
+<P>
+For example, the character class [aeiou] matches any lower case vowel, while
+[^aeiou] matches any character that is not a lower case vowel. Note that a
+circumflex is just a convenient notation for specifying the characters which
+are in the class by enumerating those that are not. It is not an assertion: it
+still consumes a character from the subject string, and fails if the current
+pointer is at the end of the string.
+</P>
+<P>
+When caseless matching is set, any letters in a class represent both their
+upper case and lower case versions, so for example, a caseless [aeiou] matches
+"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a
+caseful version would.
+</P>
+<P>
+The newline character is never treated in any special way in character classes,
+whatever the setting of the PCRE_DOTALL or PCRE_MULTILINE options is. A class
+such as [^a] will always match a newline.
+</P>
+<P>
+The minus (hyphen) character can be used to specify a range of characters in a
+character class. For example, [d-m] matches any letter between d and m,
+inclusive. If a minus character is required in a class, it must be escaped with
+a backslash or appear in a position where it cannot be interpreted as
+indicating a range, typically as the first or last character in the class.
+</P>
+<P>
+It is not possible to have the literal character "]" as the end character of a
+range. A pattern such as [W-]46] is interpreted as a class of two characters
+("W" and "-") followed by a literal string "46]", so it would match "W46]" or
+"-46]". However, if the "]" is escaped with a backslash it is interpreted as
+the end of range, so [W-\]46] is interpreted as a single class containing a
+range followed by two separate characters. The octal or hexadecimal
+representation of "]" can also be used to end a range.
+</P>
+<P>
+Ranges operate in ASCII collating sequence. They can also be used for
+characters specified numerically, for example [\000-\037]. If a range that
+includes letters is used when caseless matching is set, it matches the letters
+in either case. For example, [W-c] is equivalent to [][\^_`wxyzabc], matched
+caselessly, and if character tables for the "fr" locale are in use,
+[\xc8-\xcb] matches accented E characters in both cases.
+</P>
+<P>
+The character types \d, \D, \s, \S, \w, and \W may also appear in a
+character class, and add the characters that they match to the class. For
+example, [\dABCDEF] matches any hexadecimal digit. A circumflex can
+conveniently be used with the upper case character types to specify a more
+restricted set of characters than the matching lower case type. For example,
+the class [^\W_] matches any letter or digit, but not underscore.
+</P>
+<P>
+All non-alphameric characters other than \, -, ^ (at the start) and the
+terminating ] are non-special in character classes, but it does no harm if they
+are escaped.
+</P>
+<LI><A NAME="SEC18" HREF="#TOC1">POSIX CHARACTER CLASSES</A>
+<P>
+Perl 5.6 (not yet released at the time of writing) is going to support the
+POSIX notation for character classes, which uses names enclosed by [: and :]
+within the enclosing square brackets. PCRE supports this notation. For example,
+</P>
+<P>
+<PRE>
+ [01[:alpha:]%]
+</PRE>
+</P>
+<P>
+matches "0", "1", any alphabetic character, or "%". The supported class names
+are
+</P>
+<P>
+<PRE>
+ alnum letters and digits
+ alpha letters
+ ascii character codes 0 - 127
+ cntrl control characters
+ digit decimal digits (same as \d)
+ graph printing characters, excluding space
+ lower lower case letters
+ print printing characters, including space
+ punct printing characters, excluding letters and digits
+ space white space (same as \s)
+ upper upper case letters
+ word "word" characters (same as \w)
+ xdigit hexadecimal digits
+</PRE>
+</P>
+<P>
+The names "ascii" and "word" are Perl extensions. Another Perl extension is
+negation, which is indicated by a ^ character after the colon. For example,
+</P>
+<P>
+<PRE>
+ [12[:^digit:]]
+</PRE>
+</P>
+<P>
+matches "1", "2", or any non-digit. PCRE (and Perl) also recognize the POSIX
+syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
+supported, and an error is given if they are encountered.
+</P>
+<LI><A NAME="SEC19" HREF="#TOC1">VERTICAL BAR</A>
+<P>
+Vertical bar characters are used to separate alternative patterns. For example,
+the pattern
+</P>
+<P>
+<PRE>
+ gilbert|sullivan
+</PRE>
+</P>
+<P>
+matches either "gilbert" or "sullivan". Any number of alternatives may appear,
+and an empty alternative is permitted (matching the empty string).
+The matching process tries each alternative in turn, from left to right,
+and the first one that succeeds is used. If the alternatives are within a
+subpattern (defined below), "succeeds" means matching the rest of the main
+pattern as well as the alternative in the subpattern.
+</P>
+<LI><A NAME="SEC20" HREF="#TOC1">INTERNAL OPTION SETTING</A>
+<P>
+The settings of PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and PCRE_EXTENDED
+can be changed from within the pattern by a sequence of Perl option letters
+enclosed between "(?" and ")". The option letters are
+</P>
+<P>
+<PRE>
+ i for PCRE_CASELESS
+ m for PCRE_MULTILINE
+ s for PCRE_DOTALL
+ x for PCRE_EXTENDED
+</PRE>
+</P>
+<P>
+For example, (?im) sets caseless, multiline matching. It is also possible to
+unset these options by preceding the letter with a hyphen, and a combined
+setting and unsetting such as (?im-sx), which sets PCRE_CASELESS and
+PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, is also
+permitted. If a letter appears both before and after the hyphen, the option is
+unset.
+</P>
+<P>
+The scope of these option changes depends on where in the pattern the setting
+occurs. For settings that are outside any subpattern (defined below), the
+effect is the same as if the options were set or unset at the start of
+matching. The following patterns all behave in exactly the same way:
+</P>
+<P>
+<PRE>
+ (?i)abc
+ a(?i)bc
+ ab(?i)c
+ abc(?i)
+</PRE>
+</P>
+<P>
+which in turn is the same as compiling the pattern abc with PCRE_CASELESS set.
+In other words, such "top level" settings apply to the whole pattern (unless
+there are other changes inside subpatterns). If there is more than one setting
+of the same option at top level, the rightmost setting is used.
+</P>
+<P>
+If an option change occurs inside a subpattern, the effect is different. This
+is a change of behaviour in Perl 5.005. An option change inside a subpattern
+affects only that part of the subpattern that follows it, so
+</P>
+<P>
+<PRE>
+ (a(?i)b)c
+</PRE>
+</P>
+<P>
+matches abc and aBc and no other strings (assuming PCRE_CASELESS is not used).
+By this means, options can be made to have different settings in different
+parts of the pattern. Any changes made in one alternative do carry on
+into subsequent branches within the same subpattern. For example,
+</P>
+<P>
+<PRE>
+ (a(?i)b|c)
+</PRE>
+</P>
+<P>
+matches "ab", "aB", "c", and "C", even though when matching "C" the first
+branch is abandoned before the option setting. This is because the effects of
+option settings happen at compile time. There would be some very weird
+behaviour otherwise.
+</P>
+<P>
+The PCRE-specific options PCRE_UNGREEDY and PCRE_EXTRA can be changed in the
+same way as the Perl-compatible options by using the characters U and X
+respectively. The (?X) flag setting is special in that it must always occur
+earlier in the pattern than any of the additional features it turns on, even
+when it is at top level. It is best put at the start.
+</P>
+<LI><A NAME="SEC21" HREF="#TOC1">SUBPATTERNS</A>
+<P>
+Subpatterns are delimited by parentheses (round brackets), which can be nested.
+Marking part of a pattern as a subpattern does two things:
+</P>
+<P>
+1. It localizes a set of alternatives. For example, the pattern
+</P>
+<P>
+<PRE>
+ cat(aract|erpillar|)
+</PRE>
+</P>
+<P>
+matches one of the words "cat", "cataract", or "caterpillar". Without the
+parentheses, it would match "cataract", "erpillar" or the empty string.
+</P>
+<P>
+2. It sets up the subpattern as a capturing subpattern (as defined above).
+When the whole pattern matches, that portion of the subject string that matched
+the subpattern is passed back to the caller via the <I>ovector</I> argument of
+<B>pcre_exec()</B>. Opening parentheses are counted from left to right (starting
+from 1) to obtain the numbers of the capturing subpatterns.
+</P>
+<P>
+For example, if the string "the red king" is matched against the pattern
+</P>
+<P>
+<PRE>
+ the ((red|white) (king|queen))
+</PRE>
+</P>
+<P>
+the captured substrings are "red king", "red", and "king", and are numbered 1,
+2, and 3, respectively.
+</P>
+<P>
+The fact that plain parentheses fulfil two functions is not always helpful.
+There are often times when a grouping subpattern is required without a
+capturing requirement. If an opening parenthesis is followed by "?:", the
+subpattern does not do any capturing, and is not counted when computing the
+number of any subsequent capturing subpatterns. For example, if the string "the
+white queen" is matched against the pattern
+</P>
+<P>
+<PRE>
+ the ((?:red|white) (king|queen))
+</PRE>
+</P>
+<P>
+the captured substrings are "white queen" and "queen", and are numbered 1 and
+2. The maximum number of captured substrings is 99, and the maximum number of
+all subpatterns, both capturing and non-capturing, is 200.
+</P>
+<P>
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing subpattern, the option letters may appear between the "?" and
+the ":". Thus the two patterns
+</P>
+<P>
+<PRE>
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+</PRE>
+</P>
+<P>
+match exactly the same set of strings. Because alternative branches are tried
+from left to right, and options are not reset until the end of the subpattern
+is reached, an option setting in one branch does affect subsequent branches, so
+the above patterns match "SUNDAY" as well as "Saturday".
+</P>
+<LI><A NAME="SEC22" HREF="#TOC1">REPETITION</A>
+<P>
+Repetition is specified by quantifiers, which can follow any of the following
+items:
+</P>
+<P>
+<PRE>
+ a single character, possibly escaped
+ the . metacharacter
+ a character class
+ a back reference (see next section)
+ a parenthesized subpattern (unless it is an assertion - see below)
+</PRE>
+</P>
+<P>
+The general repetition quantifier specifies a minimum and maximum number of
+permitted matches, by giving the two numbers in curly brackets (braces),
+separated by a comma. The numbers must be less than 65536, and the first must
+be less than or equal to the second. For example:
+</P>
+<P>
+<PRE>
+ z{2,4}
+</PRE>
+</P>
+<P>
+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
+character. If the second number is omitted, but the comma is present, there is
+no upper limit; if the second number and the comma are both omitted, the
+quantifier specifies an exact number of required matches. Thus
+</P>
+<P>
+<PRE>
+ [aeiou]{3,}
+</PRE>
+</P>
+<P>
+matches at least 3 successive vowels, but may match many more, while
+</P>
+<P>
+<PRE>
+ \d{8}
+</PRE>
+</P>
+<P>
+matches exactly 8 digits. An opening curly bracket that appears in a position
+where a quantifier is not allowed, or one that does not match the syntax of a
+quantifier, is taken as a literal character. For example, {,6} is not a
+quantifier, but a literal string of four characters.
+</P>
+<P>
+The quantifier {0} is permitted, causing the expression to behave as if the
+previous item and the quantifier were not present.
+</P>
+<P>
+For convenience (and historical compatibility) the three most common
+quantifiers have single-character abbreviations:
+</P>
+<P>
+<PRE>
+ * is equivalent to {0,}
+ + is equivalent to {1,}
+ ? is equivalent to {0,1}
+</PRE>
+</P>
+<P>
+It is possible to construct infinite loops by following a subpattern that can
+match no characters with a quantifier that has no upper limit, for example:
+</P>
+<P>
+<PRE>
+ (a?)*
+</PRE>
+</P>
+<P>
+Earlier versions of Perl and PCRE used to give an error at compile time for
+such patterns. However, because there are cases where this can be useful, such
+patterns are now accepted, but if any repetition of the subpattern does in fact
+match no characters, the loop is forcibly broken.
+</P>
+<P>
+By default, the quantifiers are "greedy", that is, they match as much as
+possible (up to the maximum number of permitted times), without causing the
+rest of the pattern to fail. The classic example of where this gives problems
+is in trying to match comments in C programs. These appear between the
+sequences /* and */ and within the sequence, individual * and / characters may
+appear. An attempt to match C comments by applying the pattern
+</P>
+<P>
+<PRE>
+ /\*.*\*/
+</PRE>
+</P>
+<P>
+to the string
+</P>
+<P>
+<PRE>
+ /* first command */ not comment /* second comment */
+</PRE>
+</P>
+<P>
+fails, because it matches the entire string owing to the greediness of the .*
+item.
+</P>
+<P>
+However, if a quantifier is followed by a question mark, it ceases to be
+greedy, and instead matches the minimum number of times possible, so the
+pattern
+</P>
+<P>
+<PRE>
+ /\*.*?\*/
+</PRE>
+</P>
+<P>
+does the right thing with the C comments. The meaning of the various
+quantifiers is not otherwise changed, just the preferred number of matches.
+Do not confuse this use of question mark with its use as a quantifier in its
+own right. Because it has two uses, it can sometimes appear doubled, as in
+</P>
+<P>
+<PRE>
+ \d??\d
+</PRE>
+</P>
+<P>
+which matches one digit by preference, but can match two if that is the only
+way the rest of the pattern matches.
+</P>
+<P>
+If the PCRE_UNGREEDY option is set (an option which is not available in Perl),
+the quantifiers are not greedy by default, but individual ones can be made
+greedy by following them with a question mark. In other words, it inverts the
+default behaviour.
+</P>
+<P>
+When a parenthesized subpattern is quantified with a minimum repeat count that
+is greater than 1 or with a limited maximum, more store is required for the
+compiled pattern, in proportion to the size of the minimum or maximum.
+</P>
+<P>
+If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equivalent
+to Perl's /s) is set, thus allowing the . to match newlines, the pattern is
+implicitly anchored, because whatever follows will be tried against every
+character position in the subject string, so there is no point in retrying the
+overall match at any position after the first. PCRE treats such a pattern as
+though it were preceded by \A. In cases where it is known that the subject
+string contains no newlines, it is worth setting PCRE_DOTALL when the pattern
+begins with .* in order to obtain this optimization, or alternatively using ^
+to indicate anchoring explicitly.
+</P>
+<P>
+When a capturing subpattern is repeated, the value captured is the substring
+that matched the final iteration. For example, after
+</P>
+<P>
+<PRE>
+ (tweedle[dume]{3}\s*)+
+</PRE>
+</P>
+<P>
+has matched "tweedledum tweedledee" the value of the captured substring is
+"tweedledee". However, if there are nested capturing subpatterns, the
+corresponding captured values may have been set in previous iterations. For
+example, after
+</P>
+<P>
+<PRE>
+ /(a|(b))+/
+</PRE>
+</P>
+<P>
+matches "aba" the value of the second captured substring is "b".
+</P>
+<LI><A NAME="SEC23" HREF="#TOC1">BACK REFERENCES</A>
+<P>
+Outside a character class, a backslash followed by a digit greater than 0 (and
+possibly further digits) is a back reference to a capturing subpattern earlier
+(i.e. to its left) in the pattern, provided there have been that many previous
+capturing left parentheses.
+</P>
+<P>
+However, if the decimal number following the backslash is less than 10, it is
+always taken as a back reference, and causes an error only if there are not
+that many capturing left parentheses in the entire pattern. In other words, the
+parentheses that are referenced need not be to the left of the reference for
+numbers less than 10. See the section entitled "Backslash" above for further
+details of the handling of digits following a backslash.
+</P>
+<P>
+A back reference matches whatever actually matched the capturing subpattern in
+the current subject string, rather than anything matching the subpattern
+itself. So the pattern
+</P>
+<P>
+<PRE>
+ (sens|respons)e and \1ibility
+</PRE>
+</P>
+<P>
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If caseful matching is in force at the time of the
+back reference, the case of letters is relevant. For example,
+</P>
+<P>
+<PRE>
+ ((?i)rah)\s+\1
+</PRE>
+</P>
+<P>
+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
+capturing subpattern is matched caselessly.
+</P>
+<P>
+There may be more than one back reference to the same subpattern. If a
+subpattern has not actually been used in a particular match, any back
+references to it always fail. For example, the pattern
+</P>
+<P>
+<PRE>
+ (a|(bc))\2
+</PRE>
+</P>
+<P>
+always fails if it starts to match "a" rather than "bc". Because there may be
+up to 99 back references, all digits following the backslash are taken
+as part of a potential back reference number. If the pattern continues with a
+digit character, some delimiter must be used to terminate the back reference.
+If the PCRE_EXTENDED option is set, this can be whitespace. Otherwise an empty
+comment can be used.
+</P>
+<P>
+A back reference that occurs inside the parentheses to which it refers fails
+when the subpattern is first used, so, for example, (a\1) never matches.
+However, such references can be useful inside repeated subpatterns. For
+example, the pattern
+</P>
+<P>
+<PRE>
+ (a|b\1)+
+</PRE>
+</P>
+<P>
+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
+the subpattern, the back reference matches the character string corresponding
+to the previous iteration. In order for this to work, the pattern must be such
+that the first iteration does not need to match the back reference. This can be
+done using alternation, as in the example above, or by a quantifier with a
+minimum of zero.
+</P>
+<LI><A NAME="SEC24" HREF="#TOC1">ASSERTIONS</A>
+<P>
+An assertion is a test on the characters following or preceding the current
+matching point that does not actually consume any characters. The simple
+assertions coded as \b, \B, \A, \Z, \z, ^ and $ are described above. More
+complicated assertions are coded as subpatterns. There are two kinds: those
+that look ahead of the current position in the subject string, and those that
+look behind it.
+</P>
+<P>
+An assertion subpattern is matched in the normal way, except that it does not
+cause the current matching position to be changed. Lookahead assertions start
+with (?= for positive assertions and (?! for negative assertions. For example,
+</P>
+<P>
+<PRE>
+ \w+(?=;)
+</PRE>
+</P>
+<P>
+matches a word followed by a semicolon, but does not include the semicolon in
+the match, and
+</P>
+<P>
+<PRE>
+ foo(?!bar)
+</PRE>
+</P>
+<P>
+matches any occurrence of "foo" that is not followed by "bar". Note that the
+apparently similar pattern
+</P>
+<P>
+<PRE>
+ (?!foo)bar
+</PRE>
+</P>
+<P>
+does not find an occurrence of "bar" that is preceded by something other than
+"foo"; it finds any occurrence of "bar" whatsoever, because the assertion
+(?!foo) is always true when the next three characters are "bar". A
+lookbehind assertion is needed to achieve this effect.
+</P>
+<P>
+Lookbehind assertions start with (?&#60;= for positive assertions and (?&#60;! for
+negative assertions. For example,
+</P>
+<P>
+<PRE>
+ (?&#60;!foo)bar
+</PRE>
+</P>
+<P>
+does find an occurrence of "bar" that is not preceded by "foo". The contents of
+a lookbehind assertion are restricted such that all the strings it matches must
+have a fixed length. However, if there are several alternatives, they do not
+all have to have the same fixed length. Thus
+</P>
+<P>
+<PRE>
+ (?&#60;=bullock|donkey)
+</PRE>
+</P>
+<P>
+is permitted, but
+</P>
+<P>
+<PRE>
+ (?&#60;!dogs?|cats?)
+</PRE>
+</P>
+<P>
+causes an error at compile time. Branches that match different length strings
+are permitted only at the top level of a lookbehind assertion. This is an
+extension compared with Perl 5.005, which requires all branches to match the
+same length of string. An assertion such as
+</P>
+<P>
+<PRE>
+ (?&#60;=ab(c|de))
+</PRE>

+<P>
+The implementation of lookbehind assertions is, for each alternative, to
+temporarily move the current position back by the fixed width and then try to
+match. If there are insufficient characters before the current position, the
+match is deemed to fail. Lookbehinds in conjunction with once-only subpatterns
+can be particularly useful for matching at the ends of strings; an example is
+given at the end of the section on once-only subpatterns.
+</P>
+<P>
+Several assertions (of any sort) may occur in succession. For example,
+</P>
+<P>
+<PRE>
+ (?&#60;=\d{3})(?&#60;!999)foo
+</PRE>
+</P>
+<P>
+matches "foo" preceded by three digits that are not "999". Notice that each of
+the assertions is applied independently at the same point in the subject
+string. First there is a check that the previous three characters are all
+digits, and then there is a check that the same three characters are not "999".
+This pattern does <I>not</I> match "foo" preceded by six characters, the first
+of which are digits and the last three of which are not "999". For example, it
+doesn't match "123abcfoo". A pattern to do that is
+</P>
+<P>
+<PRE>
+ (?&#60;=\d{3}...)(?&#60;!999)foo
+</PRE>
+</P>
+<P>
+This time the first assertion looks at the preceding six characters, checking
+that the first three are digits, and then the second assertion checks that the
+preceding three characters are not "999".
+</P>
+<P>
+Assertions can be nested in any combination. For example,
+</P>
+<P>
+<PRE>
+ (?&#60;=(?&#60;!foo)bar)baz
+</PRE>
+</P>
+<P>
+matches an occurrence of "baz" that is preceded by "bar" which in turn is not
+preceded by "foo", while
+</P>
+<P>
+<PRE>
+ (?&#60;=\d{3}(?!999)...)foo
+</PRE>
+</P>
+<P>
+is another pattern which matches "foo" preceded by three digits and any three
+characters that are not "999".
+</P>
+<P>
+Assertion subpatterns are not capturing subpatterns, and may not be repeated,
+because it makes no sense to assert the same thing several times. If any kind
+of assertion contains capturing subpatterns within it, these are counted for
+the purposes of numbering the capturing subpatterns in the whole pattern.
+However, substring capturing is carried out only for positive assertions,
+because it does not make sense for negative assertions.
+</P>
+<P>
+Assertions count towards the maximum of 200 parenthesized subpatterns.
+</P>
+<LI><A NAME="SEC25" HREF="#TOC1">ONCE-ONLY SUBPATTERNS</A>
+<P>
+With both maximizing and minimizing repetition, failure of what follows
+normally causes the repeated item to be re-evaluated to see if a different
+number of repeats allows the rest of the pattern to match. Sometimes it is
+useful to prevent this, either to change the nature of the match, or to cause
+it fail earlier than it otherwise might, when the author of the pattern knows
+there is no point in carrying on.
+</P>
+<P>
+Consider, for example, the pattern \d+foo when applied to the subject line
+</P>
+<P>
+<PRE>
+ 123456bar
+</PRE>
+</P>
+<P>
+After matching all 6 digits and then failing to match "foo", the normal
+action of the matcher is to try again with only 5 digits matching the \d+
+item, and then with 4, and so on, before ultimately failing. Once-only
+subpatterns provide the means for specifying that once a portion of the pattern
+has matched, it is not to be re-evaluated in this way, so the matcher would
+give up immediately on failing to match "foo" the first time. The notation is
+another kind of special parenthesis, starting with (?&#62; as in this example:
+</P>
+<P>
+<PRE>
+ (?&#62;\d+)bar
+</PRE>
+</P>
+<P>
+This kind of parenthesis "locks up" the part of the pattern it contains once
+it has matched, and a failure further into the pattern is prevented from
+backtracking into it. Backtracking past it to previous items, however, works as
+normal.
+</P>
+<P>
+An alternative description is that a subpattern of this type matches the string
+of characters that an identical standalone pattern would match, if anchored at
+the current point in the subject string.
+</P>
+<P>
+Once-only subpatterns are not capturing subpatterns. Simple cases such as the
+above example can be thought of as a maximizing repeat that must swallow
+everything it can. So, while both \d+ and \d+? are prepared to adjust the
+number of digits they match in order to make the rest of the pattern match,
+(?&#62;\d+) can only match an entire sequence of digits.
+</P>
+<P>
+This construction can of course contain arbitrarily complicated subpatterns,
+and it can be nested.
+</P>
+<P>
+Once-only subpatterns can be used in conjunction with lookbehind assertions to
+specify efficient matching at the end of the subject string. Consider a simple
+pattern such as
+</P>
+<P>
+<PRE>
+ abcd$
+</PRE>
+</P>
+<P>
+when applied to a long string which does not match. Because matching proceeds
+from left to right, PCRE will look for each "a" in the subject and then see if
+what follows matches the rest of the pattern. If the pattern is specified as
+</P>
+<P>
+<PRE>
+ ^.*abcd$
+</PRE>
+</P>
+<P>
+the initial .* matches the entire string at first, but when this fails (because
+there is no following "a"), it backtracks to match all but the last character,
+then all but the last two characters, and so on. Once again the search for "a"
+covers the entire string, from right to left, so we are no better off. However,
+if the pattern is written as
+</P>
+<P>
+<PRE>
+ ^(?&#62;.*)(?&#60;=abcd)
+</PRE>
+</P>
+<P>
+there can be no backtracking for the .* item; it can match only the entire
+string. The subsequent lookbehind assertion does a single test on the last four
+characters. If it fails, the match fails immediately. For long strings, this
+approach makes a significant difference to the processing time.
+</P>
+<P>
+When a pattern contains an unlimited repeat inside a subpattern that can itself
+be repeated an unlimited number of times, the use of a once-only subpattern is
+the only way to avoid some failing matches taking a very long time indeed.
+The pattern
+</P>
+<P>
+<PRE>
+ (\D+|&#60;\d+&#62;)*[!?]
+</PRE>
+</P>
+<P>
+matches an unlimited number of substrings that either consist of non-digits, or
+digits enclosed in &#60;&#62;, followed by either ! or ?. When it matches, it runs
+quickly. However, if it is applied to
+</P>
+<P>
+<PRE>
+ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+</PRE>
+</P>
+<P>
+it takes a long time before reporting failure. This is because the string can
+be divided between the two repeats in a large number of ways, and all have to
+be tried. (The example used [!?] rather than a single character at the end,
+because both PCRE and Perl have an optimization that allows for fast failure
+when a single character is used. They remember the last single character that
+is required for a match, and fail early if it is not present in the string.)
+If the pattern is changed to
+</P>
+<P>
+<PRE>
+ ((?&#62;\D+)|&#60;\d+&#62;)*[!?]

+<LI><A NAME="SEC26" HREF="#TOC1">CONDITIONAL SUBPATTERNS</A>
+<P>
+It is possible to cause the matching process to obey a subpattern
+conditionally or to choose between two alternative subpatterns, depending on
+the result of an assertion, or whether a previous capturing subpattern matched
+or not. The two possible forms of conditional subpattern are
+</P>
+<P>
+<PRE>
+ (?(condition)yes-pattern)
+ (?(condition)yes-pattern|no-pattern)
+</PRE>
+</P>
+<P>
+If the condition is satisfied, the yes-pattern is used; otherwise the
+no-pattern (if present) is used. If there are more than two alternatives in the
+subpattern, a compile-time error occurs.
+</P>
+<P>
+There are two kinds of condition. If the text between the parentheses consists
+of a sequence of digits, the condition is satisfied if the capturing subpattern
+of that number has previously matched. The number must be greater than zero.
+Consider the following pattern, which contains non-significant white space to
+make it more readable (assume the PCRE_EXTENDED option) and to divide it into
+three parts for ease of discussion:
+</P>
+<P>
+<PRE>
+ ( \( )? [^()]+ (?(1) \) )
+</PRE>
+</P>
+<P>
+The first part matches an optional opening parenthesis, and if that
+character is present, sets it as the first captured substring. The second part
+matches one or more characters that are not parentheses. The third part is a
+conditional subpattern that tests whether the first set of parentheses matched
+or not. If they did, that is, if subject started with an opening parenthesis,
+the condition is true, and so the yes-pattern is executed and a closing
+parenthesis is required. Otherwise, since no-pattern is not present, the
+subpattern matches nothing. In other words, this pattern matches a sequence of
+non-parentheses, optionally enclosed in parentheses.
+</P>
+<P>
+If the condition is not a sequence of digits, it must be an assertion. This may
+be a positive or negative lookahead or lookbehind assertion. Consider this
+pattern, again containing non-significant white space, and with the two
+alternatives on the second line:
+</P>
+<P>
+<PRE>
+ (?(?=[^a-z]*[a-z])
+ \d{2}-[a-z]{3}-\d{2} | \d{2}-\d{2}-\d{2} )
+</PRE>
+</P>
+<P>
+The condition is a positive lookahead assertion that matches an optional
+sequence of non-letters followed by a letter. In other words, it tests for the
+presence of at least one letter in the subject. If a letter is found, the
+subject is matched against the first alternative; otherwise it is matched
+against the second. This pattern matches strings in one of the two forms
+dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
+</P>
+<LI><A NAME="SEC27" HREF="#TOC1">COMMENTS</A>
+<P>
+The sequence (?# marks the start of a comment which continues up to the next
+closing parenthesis. Nested parentheses are not permitted. The characters
+that make up a comment play no part in the pattern matching at all.
+</P>
+<P>
+If the PCRE_EXTENDED option is set, an unescaped # character outside a
+character class introduces a comment that continues up to the next newline
+character in the pattern.
+</P>
+<LI><A NAME="SEC28" HREF="#TOC1">RECURSIVE PATTERNS</A>
+<P>
+Consider the problem of matching a string in parentheses, allowing for
+unlimited nested parentheses. Without the use of recursion, the best that can
+be done is to use a pattern that matches up to some fixed depth of nesting. It
+is not possible to handle an arbitrary nesting depth. Perl 5.6 has provided an
+experimental facility that allows regular expressions to recurse (amongst other
+things). It does this by interpolating Perl code in the expression at run time,
+and the code can refer to the expression itself. A Perl pattern to solve the
+parentheses problem can be created like this:
+</P>
+<P>
+<PRE>
+ $re = qr{\( (?: (?&#62;[^()]+) | (?p{$re}) )* \)}x;
+</PRE>
+</P>
+<P>
+The (?p{...}) item interpolates Perl code at run time, and in this case refers
+recursively to the pattern in which it appears. Obviously, PCRE cannot support
+the interpolation of Perl code. Instead, the special item (?R) is provided for
+the specific case of recursion. This PCRE pattern solves the parentheses
+problem (assume the PCRE_EXTENDED option is set so that white space is
+ignored):
+</P>
+<P>
+<PRE>
+ \( ( (?&#62;[^()]+) | (?R) )* \)
+</PRE>
+</P>
+<P>
+First it matches an opening parenthesis. Then it matches any number of
+substrings which can either be a sequence of non-parentheses, or a recursive
+match of the pattern itself (i.e. a correctly parenthesized substring). Finally
+there is a closing parenthesis.
+</P>
+<P>
+This particular example pattern contains nested unlimited repeats, and so the
+use of a once-only subpattern for matching strings of non-parentheses is
+important when applying the pattern to strings that do not match. For example,
+when it is applied to
+</P>
+<P>
+<PRE>
+ (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+</PRE>
+</P>
+<P>
+it yields "no match" quickly. However, if a once-only subpattern is not used,
+the match runs for a very long time indeed because there are so many different
+ways the + and * repeats can carve up the subject, and all have to be tested
+before failure can be reported.
+</P>
+<P>
+The values set for any capturing subpatterns are those from the outermost level
+of the recursion at which the subpattern value is set. If the pattern above is
+matched against
+</P>
+<P>
+<PRE>
+ (ab(cd)ef)
+</PRE>
+</P>
+<P>
+the value for the capturing parentheses is "ef", which is the last value taken
+on at the top level. If additional parentheses are added, giving
+</P>
+<P>
+<PRE>
+ \( ( ( (?&#62;[^()]+) | (?R) )* ) \)
+ ^ ^
+ ^ ^
+</PRE>
+the string they capture is "ab(cd)ef", the contents of the top level
+parentheses. If there are more than 15 capturing parentheses in a pattern, PCRE
+has to obtain extra memory to store data during a recursion, which it does by
+using <B>pcre_malloc</B>, freeing it via <B>pcre_free</B> afterwards. If no
+memory can be obtained, it saves data for the first 15 capturing parentheses
+only, as there is no way to give an out-of-memory error from within a
+recursion.
+</P>
+<LI><A NAME="SEC29" HREF="#TOC1">PERFORMANCE</A>
+<P>
+Certain items that may appear in patterns are more efficient than others. It is
+more efficient to use a character class like [aeiou] than a set of alternatives
+such as (a|e|i|o|u). In general, the simplest construction that provides the
+required behaviour is usually the most efficient. Jeffrey Friedl's book
+contains a lot of discussion about optimizing regular expressions for efficient
+performance.
+</P>
+<P>
+When a pattern begins with .* and the PCRE_DOTALL option is set, the pattern is
+implicitly anchored by PCRE, since it can match only at the start of a subject
+string. However, if PCRE_DOTALL is not set, PCRE cannot make this optimization,
+because the . metacharacter does not then match a newline, and if the subject
+string contains newlines, the pattern may match from the character immediately
+following one of them instead of from the very start. For example, the pattern
+</P>
+<P>
+<PRE>
+ (.*) second
+</PRE>
+</P>
+<P>
+matches the subject "first\nand second" (where \n stands for a newline
+character) with the first captured substring being "and". In order to do this,
+PCRE has to retry the match starting after every newline in the subject.
+</P>
+<P>
+If you are using such a pattern with subject strings that do not contain
+newlines, the best performance is obtained by setting PCRE_DOTALL, or starting
+the pattern with ^.* to indicate explicit anchoring. That saves PCRE from
+having to scan along the subject looking for a newline to restart at.
+</P>
+<P>
+Beware of patterns that contain nested indefinite repeats. These can take a
+long time to run when applied to a string that does not match. Consider the
+pattern fragment
+</P>
+<P>
+<PRE>
+ (a+)*
+</PRE>
+</P>
+<P>
+This can match "aaaa" in 33 different ways, and this number increases very
+rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4
+times, and for each of those cases other than 0, the + repeats can match
+different numbers of times.) When the remainder of the pattern is such that the
+entire match is going to fail, PCRE has in principle to try every possible
+variation, and this can take an extremely long time.
+</P>
+<P>
+An optimization catches some of the more simple cases such as
+</P>
+<P>
+<PRE>
+ (a+)*b
+</PRE>
+</P>
+<P>
+where a literal character follows. Before embarking on the standard matching
+procedure, PCRE checks that there is a "b" later in the subject string, and if
+there is not, it fails the match immediately. However, when there is no
+following literal this optimization cannot be used. You can see the difference
+by comparing the behaviour of
+</P>
+<P>
+<PRE>
+ (a+)*\d
+</PRE>
+</P>
+<P>
+with the pattern above. The former gives a failure almost instantly when
+applied to a whole line of "a" characters, whereas the latter takes an
+appreciable time with strings longer than about 20 characters.
+</P>
+<LI><A NAME="SEC30" HREF="#TOC1">UTF-8 SUPPORT</A>
+<P>
+Starting at release 3.3, PCRE has some support for character strings encoded
+in the UTF-8 format. This is incomplete, and is regarded as experimental. In
+order to use it, you must configure PCRE to include UTF-8 support in the code,
+and, in addition, you must call <B>pcre_compile()</B> with the PCRE_UTF8 option
+flag. When you do this, both the pattern and any subject strings that are
+matched against it are treated as UTF-8 strings instead of just strings of
+bytes, but only in the cases that are mentioned below.
+</P>
+<P>
+If you compile PCRE with UTF-8 support, but do not use it at run time, the
+library will be a bit bigger, but the additional run time overhead is limited
+to testing the PCRE_UTF8 flag in several places, so should not be very large.
+</P>
+<P>
+PCRE assumes that the strings it is given contain valid UTF-8 codes. It does
+not diagnose invalid UTF-8 strings. If you pass invalid UTF-8 strings to PCRE,
+the results are undefined.
+</P>
+<P>
+Running with PCRE_UTF8 set causes these changes in the way PCRE works:
+</P>
+<P>
+1. In a pattern, the escape sequence \x{...}, where the contents of the braces
+is a string of hexadecimal digits, is interpreted as a UTF-8 character whose
+code number is the given hexadecimal number, for example: \x{1234}. This
+inserts from one to six literal bytes into the pattern, using the UTF-8
+encoding. If a non-hexadecimal digit appears between the braces, the item is
+not recognized.
+</P>
+<P>
+2. The original hexadecimal escape sequence, \xhh, generates a two-byte UTF-8
+character if its value is greater than 127.
+</P>
+<P>
+3. Repeat quantifiers are NOT correctly handled if they follow a multibyte
+character. For example, \x{100}* and \xc3+ do not work. If you want to
+repeat such characters, you must enclose them in non-capturing parentheses,
+for example (?:\x{100}), at present.
+</P>
+<P>
+4. The dot metacharacter matches one UTF-8 character instead of a single byte.
+</P>
+<P>
+5. Unlike literal UTF-8 characters, the dot metacharacter followed by a
+repeat quantifier does operate correctly on UTF-8 characters instead of
+single bytes.
+</P>
+<P>
+4. Although the \x{...} escape is permitted in a character class, characters
+whose values are greater than 255 cannot be included in a class.
+</P>
+<P>
+5. A class is matched against a UTF-8 character instead of just a single byte,
+but it can match only characters whose values are less than 256. Characters
+with greater values always fail to match a class.
+</P>
+<P>
+6. Repeated classes work correctly on multiple characters.
+</P>
+<P>
+7. Classes containing just a single character whose value is greater than 127
+(but less than 256), for example, [\x80] or [^\x{93}], do not work because
+these are optimized into single byte matches. In the first case, of course,
+the class brackets are just redundant.
+</P>
+<P>
+8. Lookbehind assertions move backwards in the subject by a fixed number of
+characters instead of a fixed number of bytes. Simple cases have been tested
+to work correctly, but there may be hidden gotchas herein.
+</P>
+<P>
+9. The character types such as \d and \w do not work correctly with UTF-8
+characters. They continue to test a single byte.
+</P>
+<P>
+10. Anything not explicitly mentioned here continues to work in bytes rather
+than in characters.
+</P>
+<P>
+The following UTF-8 features of Perl 5.6 are not implemented:
+</P>
+<P>
+1. The escape sequence \C to match a single byte.
+</P>
+<P>
+2. The use of Unicode tables and properties and escapes \p, \P, and \X.

+DESCRIPTION
+ The PCRE library is a set of functions that implement regu-
+ lar expression pattern matching using the same syntax and
+ semantics as Perl 5, with just a few differences (see
+
+ below). The current implementation corresponds to Perl
+ 5.005, with some additional features from later versions.
+ This includes some experimental, incomplete support for
+ UTF-8 encoded strings. Details of exactly what is and what
+ is not supported are given below.
+
+ PCRE has its own native API, which is described in this
+ document. There is also a set of wrapper functions that
+ correspond to the POSIX regular expression API. These are
+ described in the pcreposix documentation.
+
+ The native API function prototypes are defined in the header
+ file pcre.h, and on Unix systems the library itself is
+ called libpcre.a, so can be accessed by adding -lpcre to the
+ command for linking an application which calls it. The
+ header file defines the macros PCRE_MAJOR and PCRE_MINOR to
+ contain the major and minor release numbers for the library.
+ Applications can use these to include support for different
+ releases.
+
+ The functions pcre_compile(), pcre_study(), and pcre_exec()
+ are used for compiling and matching regular expressions. A
+ sample program that demonstrates the simplest way of using
+ them is given in the file pcredemo.c. The last section of
+ this man page describes how to run it.
+
+ The functions pcre_copy_substring(), pcre_get_substring(),
+ and pcre_get_substring_list() are convenience functions for
+ extracting captured substrings from a matched subject
+ string; pcre_free_substring() and pcre_free_substring_list()
+ are also provided, to free the memory used for extracted
+ strings.
+
+ The function pcre_maketables() is used (optionally) to build
+ a set of character tables in the current locale for passing
+ to pcre_compile().
+
+ The function pcre_fullinfo() is used to find out information
+ about a compiled pattern; pcre_info() is an obsolete version
+ which returns only some of the available information, but is
+ retained for backwards compatibility. The function
+ pcre_version() returns a pointer to a string containing the
+ version of PCRE and its date of release.
+
+ The global variables pcre_malloc and pcre_free initially
+ contain the entry points of the standard malloc() and free()
+ functions respectively. PCRE calls the memory management
+ functions via these variables, so a calling program can
+ replace them if it wishes to intercept the calls. This
+ should be done before calling any PCRE functions.
+
+
+
+MULTI-THREADING
+ The PCRE functions can be used in multi-threading applica-
+ tions, with the proviso that the memory management functions
+ pointed to by pcre_malloc and pcre_free are shared by all
+ threads.
+
+ The compiled form of a regular expression is not altered
+ during matching, so the same compiled pattern can safely be
+ used by several threads at once.
+
+
+
+COMPILING A PATTERN
+ The function pcre_compile() is called to compile a pattern
+ into an internal form. The pattern is a C string terminated
+ by a binary zero, and is passed in the argument pattern. A
+ pointer to a single block of memory that is obtained via
+ pcre_malloc is returned. This contains the compiled code and
+ related data. The pcre type is defined for the returned
+ block; this is a typedef for a structure whose contents are
+ not externally defined. It is up to the caller to free the
+ memory when it is no longer required.
+
+ Although the compiled code of a PCRE regex is relocatable,
+ that is, it does not depend on memory location, the complete
+ pcre data block is not fully relocatable, because it con-
+ tains a copy of the tableptr argument, which is an address
+ (see below).
+
+ The size of a compiled pattern is roughly proportional to
+ the length of the pattern string, except that each character
+ class (other than those containing just a single character,
+ negated or not) requires 33 bytes, and repeat quantifiers
+ with a minimum greater than one or a bounded maximum cause
+ the relevant portions of the compiled pattern to be repli-
+ cated.
+
+ The options argument contains independent bits that affect
+ the compilation. It should be zero if no options are
+ required. Some of the options, in particular, those that are
+ compatible with Perl, can also be set and unset from within
+ the pattern (see the detailed description of regular expres-
+ sions below). For these options, the contents of the options
+ argument specifies their initial settings at the start of
+ compilation and execution. The PCRE_ANCHORED option can be
+ set at the time of matching as well as at compile time.
+
+ If errptr is NULL, pcre_compile() returns NULL immediately.
+ Otherwise, if compilation of a pattern fails, pcre_compile()
+ returns NULL, and sets the variable pointed to by errptr to
+ point to a textual error message. The offset from the start
+ of the pattern to the character where the error was
+ discovered is placed in the variable pointed to by
+ erroffset, which must not be NULL. If it is, an immediate
+ error is given.
+
+ If the final argument, tableptr, is NULL, PCRE uses a
+ default set of character tables which are built when it is
+ compiled, using the default C locale. Otherwise, tableptr
+ must be the result of a call to pcre_maketables(). See the
+ section on locale support below.
+
+ This code fragment shows a typical straightforward call to
+ pcre_compile():
+
+ pcre *re;
+ const char *error;
+ int erroffset;
+ re = pcre_compile(
+ "^A.*Z", /* the pattern */
+ 0, /* default options */
+ &error, /* for error message */
+ &erroffset, /* for error offset */
+ NULL); /* use default character tables */
+
+ The following option bits are defined in the header file:
+
+ PCRE_ANCHORED
+
+ If this bit is set, the pattern is forced to be "anchored",
+ that is, it is constrained to match only at the start of the
+ string which is being searched (the "subject string"). This
+ effect can also be achieved by appropriate constructs in the
+ pattern itself, which is the only way to do it in Perl.
+
+ PCRE_CASELESS
+
+ If this bit is set, letters in the pattern match both upper
+ and lower case letters. It is equivalent to Perl's /i
+ option.
+
+ PCRE_DOLLAR_ENDONLY
+
+ If this bit is set, a dollar metacharacter in the pattern
+ matches only at the end of the subject string. Without this
+ option, a dollar also matches immediately before the final
+ character if it is a newline (but not before any other new-
+ lines). The PCRE_DOLLAR_ENDONLY option is ignored if
+ PCRE_MULTILINE is set. There is no equivalent to this option
+ in Perl.
+
+ PCRE_DOTALL
+
+ If this bit is set, a dot metacharater in the pattern
+ matches all characters, including newlines. Without it, new-
+ lines are excluded. This option is equivalent to Perl's /s
+ option. A negative class such as [^a] always matches a new-
+ line character, independent of the setting of this option.
+
+ PCRE_EXTENDED
+
+ If this bit is set, whitespace data characters in the pat-
+ tern are totally ignored except when escaped or inside a
+ character class, and characters between an unescaped # out-
+ side a character class and the next newline character,
+ inclusive, are also ignored. This is equivalent to Perl's /x
+ option, and makes it possible to include comments inside
+ complicated patterns. Note, however, that this applies only
+ to data characters. Whitespace characters may never appear
+ within special character sequences in a pattern, for example
+ within the sequence (?( which introduces a conditional sub-
+ pattern.
+
+ PCRE_EXTRA
+
+ This option was invented in order to turn on additional
+ functionality of PCRE that is incompatible with Perl, but it
+ is currently of very little use. When set, any backslash in
+ a pattern that is followed by a letter that has no special
+ meaning causes an error, thus reserving these combinations
+ for future expansion. By default, as in Perl, a backslash
+ followed by a letter with no special meaning is treated as a
+ literal. There are at present no other features controlled
+ by this option. It can also be set by a (?X) option setting
+ within a pattern.
+
+ PCRE_MULTILINE
+
+ By default, PCRE treats the subject string as consisting of
+ a single "line" of characters (even if it actually contains
+ several newlines). The "start of line" metacharacter (^)
+ matches only at the start of the string, while the "end of
+ line" metacharacter ($) matches only at the end of the
+ string, or before a terminating newline (unless
+ PCRE_DOLLAR_ENDONLY is set). This is the same as Perl.
+
+ When PCRE_MULTILINE it is set, the "start of line" and "end
+ of line" constructs match immediately following or immedi-
+ ately before any newline in the subject string, respec-
+ tively, as well as at the very start and end. This is
+ equivalent to Perl's /m option. If there are no "\n" charac-
+ ters in a subject string, or no occurrences of ^ or $ in a
+ pattern, setting PCRE_MULTILINE has no effect.
+
+ PCRE_UNGREEDY
+
+ This option inverts the "greediness" of the quantifiers so
+ that they are not greedy by default, but become greedy if
+ followed by "?". It is not compatible with Perl. It can also
+ be set by a (?U) option setting within the pattern.
+
+ PCRE_UTF8
+
+ This option causes PCRE to regard both the pattern and the
+ subject as strings of UTF-8 characters instead of just byte
+ strings. However, it is available only if PCRE has been
+ built to include UTF-8 support. If not, the use of this
+ option provokes an error. Support for UTF-8 is new, experi-
+ mental, and incomplete. Details of exactly what it entails
+ are given below.
+
+
+
+STUDYING A PATTERN
+ When a pattern is going to be used several times, it is
+ worth spending more time analyzing it in order to speed up
+ the time taken for matching. The function pcre_study() takes
+ a pointer to a compiled pattern as its first argument, and
+ returns a pointer to a pcre_extra block (another typedef for
+ a structure with hidden contents) containing additional
+ information about the pattern; this can be passed to
+ pcre_exec(). If no additional information is available, NULL
+ is returned.
+
+ The second argument contains option bits. At present, no
+ options are defined for pcre_study(), and this argument
+ should always be zero.
+
+ The third argument for pcre_study() is a pointer to an error
+ message. If studying succeeds (even if no data is returned),
+ the variable it points to is set to NULL. Otherwise it
+ points to a textual error message.
+
+ This is a typical call to pcre_study():
+
+ pcre_extra *pe;
+ pe = pcre_study(
+ re, /* result of pcre_compile() */
+ 0, /* no options exist */
+ &error); /* set to NULL or points to a message */
+
+ At present, studying a pattern is useful only for non-
+ anchored patterns that do not have a single fixed starting
+ character. A bitmap of possible starting characters is
+ created.
+
+
+
+LOCALE SUPPORT
+ PCRE handles caseless matching, and determines whether char-
+ acters are letters, digits, or whatever, by reference to a
+ set of tables. The library contains a default set of tables
+ which is created in the default C locale when PCRE is com-
+ piled. This is used when the final argument of
+ pcre_compile() is NULL, and is sufficient for many applica-
+ tions.
+
+ An alternative set of tables can, however, be supplied. Such
+ tables are built by calling the pcre_maketables() function,
+ which has no arguments, in the relevant locale. The result
+ can then be passed to pcre_compile() as often as necessary.
+ For example, to build and use tables that are appropriate
+ for the French locale (where accented characters with codes
+ greater than 128 are treated as letters), the following code
+ could be used:
+
+ setlocale(LC_CTYPE, "fr");
+ tables = pcre_maketables();
+ re = pcre_compile(..., tables);
+
+ The tables are built in memory that is obtained via
+ pcre_malloc. The pointer that is passed to pcre_compile is
+ saved with the compiled pattern, and the same tables are
+ used via this pointer by pcre_study() and pcre_exec(). Thus
+ for any single pattern, compilation, studying and matching
+ all happen in the same locale, but different patterns can be
+ compiled in different locales. It is the caller's responsi-
+ bility to ensure that the memory containing the tables
+ remains available for as long as it is needed.
+
+
+
+INFORMATION ABOUT A PATTERN
+ The pcre_fullinfo() function returns information about a
+ compiled pattern. It replaces the obsolete pcre_info() func-
+ tion, which is nevertheless retained for backwards compabil-
+ ity (and is documented below).
+
+ The first argument for pcre_fullinfo() is a pointer to the
+ compiled pattern. The second argument is the result of
+ pcre_study(), or NULL if the pattern was not studied. The
+ third argument specifies which piece of information is
+ required, while the fourth argument is a pointer to a vari-
+ able to receive the data. The yield of the function is zero
+ for success, or one of the following negative numbers:
+
+ PCRE_ERROR_NULL the argument code was NULL
+ the argument where was NULL
+ PCRE_ERROR_BADMAGIC the "magic number" was not found
+ PCRE_ERROR_BADOPTION the value of what was invalid
+
+ Here is a typical call of pcre_fullinfo(), to obtain the
+ length of the compiled pattern:
+
+ int rc;
+ unsigned long int length;
+ rc = pcre_fullinfo(
+ re, /* result of pcre_compile() */
+ pe, /* result of pcre_study(), or NULL */
+ PCRE_INFO_SIZE, /* what is required */
+ &length); /* where to put the data */
+
+ The possible values for the third argument are defined in
+ pcre.h, and are as follows:
+
+ PCRE_INFO_OPTIONS
+
+ Return a copy of the options with which the pattern was com-
+ piled. The fourth argument should point to an unsigned long
+ int variable. These option bits are those specified in the
+ call to pcre_compile(), modified by any top-level option
+ settings within the pattern itself, and with the
+ PCRE_ANCHORED bit forcibly set if the form of the pattern
+ implies that it can match only at the start of a subject
+ string.
+
+ PCRE_INFO_SIZE
+
+ Return the size of the compiled pattern, that is, the value
+ that was passed as the argument to pcre_malloc() when PCRE
+ was getting memory in which to place the compiled data. The
+ fourth argument should point to a size_t variable.
+
+ PCRE_INFO_CAPTURECOUNT
+
+ Return the number of capturing subpatterns in the pattern.
+ The fourth argument should point to an int variable.
+
+ PCRE_INFO_BACKREFMAX
+
+ Return the number of the highest back reference in the pat-
+ tern. The fourth argument should point to an int variable.
+ Zero is returned if there are no back references.
+
+ PCRE_INFO_FIRSTCHAR
+
+ Return information about the first character of any matched
+ string, for a non-anchored pattern. If there is a fixed
+ first character, e.g. from a pattern such as
+ (cat|cow|coyote), it is returned in the integer pointed to
+ by where. Otherwise, if either
+
+ (a) the pattern was compiled with the PCRE_MULTILINE option,
+ and every branch starts with "^", or
+
+ (b) every branch of the pattern starts with ".*" and
+ PCRE_DOTALL is not set (if it were set, the pattern would be
+ anchored),
+
+ -1 is returned, indicating that the pattern matches only at
+ the start of a subject string or after any "\n" within the
+ string. Otherwise -2 is returned. For anchored patterns, -2
+ is returned.
+
+ PCRE_INFO_FIRSTTABLE
+
+ If the pattern was studied, and this resulted in the con-
+ struction of a 256-bit table indicating a fixed set of char-
+ acters for the first character in any matching string, a
+ pointer to the table is returned. Otherwise NULL is
+ returned. The fourth argument should point to an unsigned
+ char * variable.
+
+ PCRE_INFO_LASTLITERAL
+
+ For a non-anchored pattern, return the value of the right-
+ most literal character which must exist in any matched
+ string, other than at its start. The fourth argument should
+ point to an int variable. If there is no such character, or
+ if the pattern is anchored, -1 is returned. For example, for
+ the pattern /a\d+z\d+/ the returned value is 'z'.
+
+ The pcre_info() function is now obsolete because its inter-
+ face is too restrictive to return all the available data
+ about a compiled pattern. New programs should use
+ pcre_fullinfo() instead. The yield of pcre_info() is the
+ number of capturing subpatterns, or one of the following
+ negative numbers:
+
+ PCRE_ERROR_NULL the argument code was NULL
+ PCRE_ERROR_BADMAGIC the "magic number" was not found
+
+ If the optptr argument is not NULL, a copy of the options
+ with which the pattern was compiled is placed in the integer
+ it points to (see PCRE_INFO_OPTIONS above).
+
+ If the pattern is not anchored and the firstcharptr argument
+ is not NULL, it is used to pass back information about the
+ first character of any matched string (see
+ PCRE_INFO_FIRSTCHAR above).
+
+
+
+MATCHING A PATTERN
+ The function pcre_exec() is called to match a subject string
+
+
+
+
+
+SunOS 5.8 Last change: 9
+
+
+
+ against a pre-compiled pattern, which is passed in the code
+ argument. If the pattern has been studied, the result of the
+ study should be passed in the extra argument. Otherwise this
+ must be NULL.
+
+ Here is an example of a simple call to pcre_exec():
+
+ int rc;
+ int ovector[30];
+ rc = pcre_exec(
+ re, /* result of pcre_compile() */
+ NULL, /* we didn't study the pattern */
+ "some string", /* the subject string */
+ 11, /* the length of the subject string */
+ 0, /* start at offset 0 in the subject */
+ 0, /* default options */
+ ovector, /* vector for substring information */
+ 30); /* number of elements in the vector */
+
+ The PCRE_ANCHORED option can be passed in the options argu-
+ ment, whose unused bits must be zero. However, if a pattern
+ was compiled with PCRE_ANCHORED, or turned out to be
+ anchored by virtue of its contents, it cannot be made
+ unachored at matching time.
+
+ There are also three further options that can be set only at
+ matching time:
+
+ PCRE_NOTBOL
+
+ The first character of the string is not the beginning of a
+ line, so the circumflex metacharacter should not match
+ before it. Setting this without PCRE_MULTILINE (at compile
+ time) causes circumflex never to match.
+
+ PCRE_NOTEOL
+
+ The end of the string is not the end of a line, so the dol-
+ lar metacharacter should not match it nor (except in multi-
+ line mode) a newline immediately before it. Setting this
+ without PCRE_MULTILINE (at compile time) causes dollar never
+ to match.
+
+ PCRE_NOTEMPTY
+
+ An empty string is not considered to be a valid match if
+ this option is set. If there are alternatives in the pat-
+ tern, they are tried. If all the alternatives match the
+ empty string, the entire match fails. For example, if the
+ pattern
+
+ a?b?
+
+ is applied to a string not beginning with "a" or "b", it
+ matches the empty string at the start of the subject. With
+ PCRE_NOTEMPTY set, this match is not valid, so PCRE searches
+ further into the string for occurrences of "a" or "b".
+
+ Perl has no direct equivalent of PCRE_NOTEMPTY, but it does
+ make a special case of a pattern match of the empty string
+ within its split() function, and when using the /g modifier.
+ It is possible to emulate Perl's behaviour after matching a
+ null string by first trying the match again at the same
+ offset with PCRE_NOTEMPTY set, and then if that fails by
+ advancing the starting offset (see below) and trying an
+ ordinary match again.
+
+ The subject string is passed as a pointer in subject, a
+ length in length, and a starting offset in startoffset.
+ Unlike the pattern string, the subject may contain binary
+ zero characters. When the starting offset is zero, the
+ search for a match starts at the beginning of the subject,
+ and this is by far the most common case.
+
+ A non-zero starting offset is useful when searching for
+ another match in the same subject by calling pcre_exec()
+ again after a previous success. Setting startoffset differs
+ from just passing over a shortened string and setting
+ PCRE_NOTBOL in the case of a pattern that begins with any
+ kind of lookbehind. For example, consider the pattern
+
+ \Biss\B
+
+ which finds occurrences of "iss" in the middle of words. (\B
+ matches only if the current position in the subject is not a
+ word boundary.) When applied to the string "Mississipi" the
+ first call to pcre_exec() finds the first occurrence. If
+ pcre_exec() is called again with just the remainder of the
+ subject, namely "issipi", it does not match, because \B is
+ always false at the start of the subject, which is deemed to
+ be a word boundary. However, if pcre_exec() is passed the
+ entire string again, but with startoffset set to 4, it finds
+ the second occurrence of "iss" because it is able to look
+ behind the starting point to discover that it is preceded by
+ a letter.
+
+ If a non-zero starting offset is passed when the pattern is
+ anchored, one attempt to match at the given offset is tried.
+ This can only succeed if the pattern does not require the
+ match to be at the start of the subject.
+
+ In general, a pattern matches a certain portion of the sub-
+ ject, and in addition, further substrings from the subject
+ may be picked out by parts of the pattern. Following the
+ usage in Jeffrey Friedl's book, this is called "capturing"
+ in what follows, and the phrase "capturing subpattern" is
+ used for a fragment of a pattern that picks out a substring.
+ PCRE supports several other kinds of parenthesized subpat-
+ tern that do not cause substrings to be captured.
+
+ Captured substrings are returned to the caller via a vector
+ of integer offsets whose address is passed in ovector. The
+ number of elements in the vector is passed in ovecsize. The
+ first two-thirds of the vector is used to pass back captured
+ substrings, each substring using a pair of integers. The
+ remaining third of the vector is used as workspace by
+ pcre_exec() while matching capturing subpatterns, and is not
+ available for passing back information. The length passed in
+ ovecsize should always be a multiple of three. If it is not,
+ it is rounded down.
+
+ When a match has been successful, information about captured
+ substrings is returned in pairs of integers, starting at the
+ beginning of ovector, and continuing up to two-thirds of its
+ length at the most. The first element of a pair is set to
+ the offset of the first character in a substring, and the
+ second is set to the offset of the first character after the
+ end of a substring. The first pair, ovector[0] and ovec-
+ tor[1], identify the portion of the subject string matched
+ by the entire pattern. The next pair is used for the first
+ capturing subpattern, and so on. The value returned by
+ pcre_exec() is the number of pairs that have been set. If
+ there are no capturing subpatterns, the return value from a
+ successful match is 1, indicating that just the first pair
+ of offsets has been set.
+
+ Some convenience functions are provided for extracting the
+ captured substrings as separate strings. These are described
+ in the following section.
+
+ It is possible for an capturing subpattern number n+1 to
+ match some part of the subject when subpattern n has not
+ been used at all. For example, if the string "abc" is
+ matched against the pattern (a|(z))(bc) subpatterns 1 and 3
+ are matched, but 2 is not. When this happens, both offset
+ values corresponding to the unused subpattern are set to -1.
+
+ If a capturing subpattern is matched repeatedly, it is the
+ last portion of the string that it matched that gets
+ returned.
+
+ If the vector is too small to hold all the captured sub-
+ strings, it is used as far as possible (up to two-thirds of
+ its length), and the function returns a value of zero. In
+ particular, if the substring offsets are not of interest,
+ pcre_exec() may be called with ovector passed as NULL and
+ ovecsize as zero. However, if the pattern contains back
+ references and the ovector isn't big enough to remember the
+ related substrings, PCRE has to get additional memory for
+ use during matching. Thus it is usually advisable to supply
+ an ovector.
+
+ Note that pcre_info() can be used to find out how many cap-
+ turing subpatterns there are in a compiled pattern. The
+ smallest size for ovector that will allow for n captured
+ substrings in addition to the offsets of the substring
+ matched by the whole pattern is (n+1)*3.
+
+ If pcre_exec() fails, it returns a negative number. The fol-
+ lowing are defined in the header file:
+
+ PCRE_ERROR_NOMATCH (-1)
+
+ The subject string did not match the pattern.
+
+ PCRE_ERROR_NULL (-2)
+
+ Either code or subject was passed as NULL, or ovector was
+ NULL and ovecsize was not zero.
+
+ PCRE_ERROR_BADOPTION (-3)
+
+ An unrecognized bit was set in the options argument.
+
+ PCRE_ERROR_BADMAGIC (-4)
+
+ PCRE stores a 4-byte "magic number" at the start of the com-
+ piled code, to catch the case when it is passed a junk
+ pointer. This is the error it gives when the magic number
+ isn't present.
+
+ PCRE_ERROR_UNKNOWN_NODE (-5)
+
+ While running the pattern match, an unknown item was encoun-
+ tered in the compiled pattern. This error could be caused by
+ a bug in PCRE or by overwriting of the compiled pattern.
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+ If a pattern contains back references, but the ovector that
+ is passed to pcre_exec() is not big enough to remember the
+ referenced substrings, PCRE gets a block of memory at the
+ start of matching to use for this purpose. If the call via
+ pcre_malloc() fails, this error is given. The memory is
+ freed at the end of matching.
+
+
+
+
+EXTRACTING CAPTURED SUBSTRINGS
+ Captured substrings can be accessed directly by using the
+ offsets returned by pcre_exec() in ovector. For convenience,
+ the functions pcre_copy_substring(), pcre_get_substring(),
+ and pcre_get_substring_list() are provided for extracting
+ captured substrings as new, separate, zero-terminated
+ strings. A substring that contains a binary zero is
+ correctly extracted and has a further zero added on the end,
+ but the result does not, of course, function as a C string.
+
+ The first three arguments are the same for all three func-
+ tions: subject is the subject string which has just been
+ successfully matched, ovector is a pointer to the vector of
+ integer offsets that was passed to pcre_exec(), and
+ stringcount is the number of substrings that were captured
+ by the match, including the substring that matched the
+ entire regular expression. This is the value returned by
+ pcre_exec if it is greater than zero. If pcre_exec()
+ returned zero, indicating that it ran out of space in ovec-
+ tor, the value passed as stringcount should be the size of
+ the vector divided by three.
+
+ The functions pcre_copy_substring() and pcre_get_substring()
+ extract a single substring, whose number is given as string-
+ number. A value of zero extracts the substring that matched
+ the entire pattern, while higher values extract the captured
+ substrings. For pcre_copy_substring(), the string is placed
+ in buffer, whose length is given by buffersize, while for
+ pcre_get_substring() a new block of memory is obtained via
+ pcre_malloc, and its address is returned via stringptr. The
+ yield of the function is the length of the string, not
+ including the terminating zero, or one of
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+ The buffer was too small for pcre_copy_substring(), or the
+ attempt to get memory failed for pcre_get_substring().
+
+ PCRE_ERROR_NOSUBSTRING (-7)
+
+ There is no substring whose number is stringnumber.
+
+ The pcre_get_substring_list() function extracts all avail-
+ able substrings and builds a list of pointers to them. All
+ this is done in a single block of memory which is obtained
+ via pcre_malloc. The address of the memory block is returned
+ via listptr, which is also the start of the list of string
+ pointers. The end of the list is marked by a NULL pointer.
+ The yield of the function is zero if all went well, or
+
+ PCRE_ERROR_NOMEMORY (-6)
+
+ if the attempt to get the memory block failed.
+
+ When any of these functions encounter a substring that is
+ unset, which can happen when capturing subpattern number n+1
+ matches some part of the subject, but subpattern n has not
+ been used at all, they return an empty string. This can be
+ distinguished from a genuine zero-length substring by
+ inspecting the appropriate offset in ovector, which is nega-
+ tive for unset substrings.
+
+ The two convenience functions pcre_free_substring() and
+ pcre_free_substring_list() can be used to free the memory
+ returned by a previous call of pcre_get_substring() or
+ pcre_get_substring_list(), respectively. They do nothing
+ more than call the function pointed to by pcre_free, which
+ of course could be called directly from a C program. How-
+ ever, PCRE is used in some situations where it is linked via
+ a special interface to another programming language which
+ cannot use pcre_free directly; it is for these cases that
+ the functions are provided.
+
+
+
+LIMITATIONS
+ There are some size limitations in PCRE but it is hoped that
+ they will never in practice be relevant. The maximum length
+ of a compiled pattern is 65539 (sic) bytes. All values in
+ repeating quantifiers must be less than 65536. There max-
+ imum number of capturing subpatterns is 65535. There is no
+ limit to the number of non-capturing subpatterns, but the
+ maximum depth of nesting of all kinds of parenthesized sub-
+ pattern, including capturing subpatterns, assertions, and
+ other types of subpattern, is 200.
+
+ The maximum length of a subject string is the largest posi-
+ tive number that an integer variable can hold. However, PCRE
+ uses recursion to handle subpatterns and indefinite repeti-
+ tion. This means that the available stack space may limit
+ the size of a subject string that can be processed by cer-
+ tain patterns.
+
+
+
+DIFFERENCES FROM PERL
+ The differences described here are with respect to Perl
+ 5.005.
+
+ 1. By default, a whitespace character is any character that
+ the C library function isspace() recognizes, though it is
+ possible to compile PCRE with alternative character type
+ tables. Normally isspace() matches space, formfeed, newline,
+ carriage return, horizontal tab, and vertical tab. Perl 5 no
+ longer includes vertical tab in its set of whitespace char-
+ acters. The \v escape that was in the Perl documentation for
+ a long time was never in fact recognized. However, the char-
+ acter itself was treated as whitespace at least up to 5.002.
+ In 5.004 and 5.005 it does not match \s.
+
+ 2. PCRE does not allow repeat quantifiers on lookahead
+ assertions. Perl permits them, but they do not mean what you
+ might think. For example, (?!a){3} does not assert that the
+ next three characters are not "a". It just asserts that the
+ next character is not "a" three times.
+
+ 3. Capturing subpatterns that occur inside negative looka-
+ head assertions are counted, but their entries in the
+ offsets vector are never set. Perl sets its numerical vari-
+ ables from any such patterns that are matched before the
+ assertion fails to match something (thereby succeeding), but
+ only if the negative lookahead assertion contains just one
+ branch.
+
+ 4. Though binary zero characters are supported in the sub-
+ ject string, they are not allowed in a pattern string
+ because it is passed as a normal C string, terminated by
+ zero. The escape sequence "\0" can be used in the pattern to
+ represent a binary zero.
+
+ 5. The following Perl escape sequences are not supported:
+ \l, \u, \L, \U, \E, \Q. In fact these are implemented by
+ Perl's general string-handling and are not part of its pat-
+ tern matching engine.
+
+ 6. The Perl \G assertion is not supported as it is not
+ relevant to single pattern matches.
+
+ 7. Fairly obviously, PCRE does not support the (?{code}) and
+ (?p{code}) constructions. However, there is some experimen-
+ tal support for recursive patterns using the non-Perl item
+ (?R).
+
+ 8. There are at the time of writing some oddities in Perl
+ 5.005_02 concerned with the settings of captured strings
+ when part of a pattern is repeated. For example, matching
+ "aba" against the pattern /^(a(b)?)+$/ sets $2 to the value
+ "b", but matching "aabbaa" against /^(aa(bb)?)+$/ leaves $2
+ unset. However, if the pattern is changed to
+ /^(aa(b(b))?)+$/ then $2 (and $3) are set.
+
+ In Perl 5.004 $2 is set in both cases, and that is also true
+ of PCRE. If in the future Perl changes to a consistent state
+ that is different, PCRE may change to follow.
+
+ 9. Another as yet unresolved discrepancy is that in Perl
+ 5.005_02 the pattern /^(a)?(?(1)a|b)+$/ matches the string
+ "a", whereas in PCRE it does not. However, in both Perl and
+ PCRE /^(a)?a/ matched against "a" leaves $1 unset.
+
+ 10. PCRE provides some extensions to the Perl regular
+ expression facilities:
+
+ (a) Although lookbehind assertions must match fixed length
+ strings, each alternative branch of a lookbehind assertion
+ can match a different length of string. Perl 5.005 requires
+ them all to have the same length.
+
+ (b) If PCRE_DOLLAR_ENDONLY is set and PCRE_MULTILINE is not
+ set, the $ meta- character matches only at the very end of
+ the string.
+
+ (c) If PCRE_EXTRA is set, a backslash followed by a letter
+ with no special meaning is faulted.
+
+ (d) If PCRE_UNGREEDY is set, the greediness of the repeti-
+ tion quantifiers is inverted, that is, by default they are
+ not greedy, but if followed by a question mark they are.
+
+ (e) PCRE_ANCHORED can be used to force a pattern to be tried
+ only at the start of the subject.
+
+ (f) The PCRE_NOTBOL, PCRE_NOTEOL, and PCRE_NOTEMPTY options
+ for pcre_exec() have no Perl equivalents.
+
+ (g) The (?R) construct allows for recursive pattern matching
+ (Perl 5.6 can do this using the (?p{code}) construct, which
+ PCRE cannot of course support.)
+
+
+
+REGULAR EXPRESSION DETAILS
+ The syntax and semantics of the regular expressions sup-
+ ported by PCRE are described below. Regular expressions are
+ also described in the Perl documentation and in a number of
+ other books, some of which have copious examples. Jeffrey
+ Friedl's "Mastering Regular Expressions", published by
+ O'Reilly (ISBN 1-56592-257), covers them in great detail.
+
+ The description here is intended as reference documentation.
+ The basic operation of PCRE is on strings of bytes. However,
+ there is the beginnings of some support for UTF-8 character
+ strings. To use this support you must configure PCRE to
+ include it, and then call pcre_compile() with the PCRE_UTF8
+ option. How this affects the pattern matching is described
+ in the final section of this document.
+
+ A regular expression is a pattern that is matched against a
+ subject string from left to right. Most characters stand for
+ themselves in a pattern, and match the corresponding charac-
+ ters in the subject. As a trivial example, the pattern
+
+ The quick brown fox
+
+ matches a portion of a subject string that is identical to
+ itself. The power of regular expressions comes from the
+ ability to include alternatives and repetitions in the pat-
+ tern. These are encoded in the pattern by the use of meta-
+ characters, which do not stand for themselves but instead
+ are interpreted in some special way.
+
+ There are two different sets of meta-characters: those that
+ are recognized anywhere in the pattern except within square
+ brackets, and those that are recognized in square brackets.
+ Outside square brackets, the meta-characters are as follows:
+
+ \ general escape character with several uses
+ ^ assert start of subject (or line, in multiline
+ mode)
+ $ assert end of subject (or line, in multiline mode)
+ . match any character except newline (by default)
+ [ start character class definition
+ | start of alternative branch
+ ( start subpattern
+ ) end subpattern
+ ? extends the meaning of (
+ also 0 or 1 quantifier
+ also quantifier minimizer
+ * 0 or more quantifier
+ + 1 or more quantifier
+ { start min/max quantifier
+
+ Part of a pattern that is in square brackets is called a
+ "character class". In a character class the only meta-
+ characters are:
+
+ \ general escape character
+ ^ negate the class, but only if the first character
+ - indicates character range
+ ] terminates the character class
+
+ The following sections describe the use of each of the
+ meta-characters.
+
+
+
+BACKSLASH
+ The backslash character has several uses. Firstly, if it is
+ followed by a non-alphameric character, it takes away any
+ special meaning that character may have. This use of
+
+ backslash as an escape character applies both inside and
+ outside character classes.
+
+ For example, if you want to match a "*" character, you write
+ "\*" in the pattern. This applies whether or not the follow-
+ ing character would otherwise be interpreted as a meta-
+ character, so it is always safe to precede a non-alphameric
+ with "\" to specify that it stands for itself. In particu-
+ lar, if you want to match a backslash, you write "\\".
+
+ If a pattern is compiled with the PCRE_EXTENDED option, whi-
+ tespace in the pattern (other than in a character class) and
+ characters between a "#" outside a character class and the
+ next newline character are ignored. An escaping backslash
+ can be used to include a whitespace or "#" character as part
+ of the pattern.
+
+ A second use of backslash provides a way of encoding non-
+ printing characters in patterns in a visible manner. There
+ is no restriction on the appearance of non-printing charac-
+ ters, apart from the binary zero that terminates a pattern,
+ but when a pattern is being prepared by text editing, it is
+ usually easier to use one of the following escape sequences
+ than the binary character it represents:
+
+ \a alarm, that is, the BEL character (hex 07)
+ \cx "control-x", where x is any character
+ \e escape (hex 1B)
+ \f formfeed (hex 0C)
+ \n newline (hex 0A)
+ \r carriage return (hex 0D)
+ \t tab (hex 09)
+ \xhh character with hex code hh
+ \ddd character with octal code ddd, or backreference
+
+ The precise effect of "\cx" is as follows: if "x" is a lower
+ case letter, it is converted to upper case. Then bit 6 of
+ the character (hex 40) is inverted. Thus "\cz" becomes hex
+ 1A, but "\c{" becomes hex 3B, while "\c;" becomes hex 7B.
+
+ After "\x", up to two hexadecimal digits are read (letters
+ can be in upper or lower case).
+
+ After "\0" up to two further octal digits are read. In both
+ cases, if there are fewer than two digits, just those that
+ are present are used. Thus the sequence "\0\x\07" specifies
+ two binary zeros followed by a BEL character. Make sure you
+ supply two digits after the initial zero if the character
+ that follows is itself an octal digit.
+
+ The handling of a backslash followed by a digit other than 0
+ is complicated. Outside a character class, PCRE reads it
+ and any following digits as a decimal number. If the number
+ is less than 10, or if there have been at least that many
+ previous capturing left parentheses in the expression, the
+ entire sequence is taken as a back reference. A description
+ of how this works is given later, following the discussion
+ of parenthesized subpatterns.
+
+ Inside a character class, or if the decimal number is
+ greater than 9 and there have not been that many capturing
+ subpatterns, PCRE re-reads up to three octal digits follow-
+ ing the backslash, and generates a single byte from the
+ least significant 8 bits of the value. Any subsequent digits
+ stand for themselves. For example:
+
+ \040 is another way of writing a space
+ \40 is the same, provided there are fewer than 40
+ previous capturing subpatterns
+ \7 is always a back reference
+ \11 might be a back reference, or another way of
+ writing a tab
+ \011 is always a tab
+ \0113 is a tab followed by the character "3"
+ \113 is the character with octal code 113 (since there
+ can be no more than 99 back references)
+ \377 is a byte consisting entirely of 1 bits
+ \81 is either a back reference, or a binary zero
+ followed by the two characters "8" and "1"
+
+ Note that octal values of 100 or greater must not be intro-
+ duced by a leading zero, because no more than three octal
+ digits are ever read.
+
+ All the sequences that define a single byte value can be
+ used both inside and outside character classes. In addition,
+ inside a character class, the sequence "\b" is interpreted
+ as the backspace character (hex 08). Outside a character
+ class it has a different meaning (see below).
+
+ The third use of backslash is for specifying generic charac-
+ ter types:
+
+ \d any decimal digit
+ \D any character that is not a decimal digit
+ \s any whitespace character
+ \S any character that is not a whitespace character
+ \w any "word" character
+ \W any "non-word" character
+
+ Each pair of escape sequences partitions the complete set of
+ characters into two disjoint sets. Any given character
+ matches one, and only one, of each pair.
+
+ A "word" character is any letter or digit or the underscore
+ character, that is, any character which can be part of a
+ Perl "word". The definition of letters and digits is con-
+ trolled by PCRE's character tables, and may vary if locale-
+ specific matching is taking place (see "Locale support"
+ above). For example, in the "fr" (French) locale, some char-
+ acter codes greater than 128 are used for accented letters,
+ and these are matched by \w.
+
+ These character type sequences can appear both inside and
+ outside character classes. They each match one character of
+ the appropriate type. If the current matching point is at
+ the end of the subject string, all of them fail, since there
+ is no character to match.
+
+ The fourth use of backslash is for certain simple asser-
+ tions. An assertion specifies a condition that has to be met
+ at a particular point in a match, without consuming any
+ characters from the subject string. The use of subpatterns
+ for more complicated assertions is described below. The
+ backslashed assertions are
+
+ \b word boundary
+ \B not a word boundary
+ \A start of subject (independent of multiline mode)
+ \Z end of subject or newline at end (independent of
+ multiline mode)
+ \z end of subject (independent of multiline mode)
+
+ These assertions may not appear in character classes (but
+ note that "\b" has a different meaning, namely the backspace
+ character, inside a character class).
+
+ A word boundary is a position in the subject string where
+ the current character and the previous character do not both
+ match \w or \W (i.e. one matches \w and the other matches
+ \W), or the start or end of the string if the first or last
+ character matches \w, respectively.
+
+ The \A, \Z, and \z assertions differ from the traditional
+ circumflex and dollar (described below) in that they only
+ ever match at the very start and end of the subject string,
+ whatever options are set. They are not affected by the
+ PCRE_NOTBOL or PCRE_NOTEOL options. If the startoffset argu-
+ ment of pcre_exec() is non-zero, \A can never match. The
+ difference between \Z and \z is that \Z matches before a
+ newline that is the last character of the string as well as
+ at the end of the string, whereas \z matches only at the
+ end.
+
+
+
+CIRCUMFLEX AND DOLLAR
+ Outside a character class, in the default matching mode, the
+ circumflex character is an assertion which is true only if
+ the current matching point is at the start of the subject
+ string. If the startoffset argument of pcre_exec() is non-
+ zero, circumflex can never match. Inside a character class,
+ circumflex has an entirely different meaning (see below).
+
+ Circumflex need not be the first character of the pattern if
+ a number of alternatives are involved, but it should be the
+ first thing in each alternative in which it appears if the
+ pattern is ever to match that branch. If all possible alter-
+ natives start with a circumflex, that is, if the pattern is
+ constrained to match only at the start of the subject, it is
+ said to be an "anchored" pattern. (There are also other con-
+ structs that can cause a pattern to be anchored.)
+
+ A dollar character is an assertion which is true only if the
+ current matching point is at the end of the subject string,
+ or immediately before a newline character that is the last
+ character in the string (by default). Dollar need not be the
+ last character of the pattern if a number of alternatives
+ are involved, but it should be the last item in any branch
+ in which it appears. Dollar has no special meaning in a
+ character class.
+
+ The meaning of dollar can be changed so that it matches only
+ at the very end of the string, by setting the
+ PCRE_DOLLAR_ENDONLY option at compile or matching time. This
+ does not affect the \Z assertion.
+
+ The meanings of the circumflex and dollar characters are
+ changed if the PCRE_MULTILINE option is set. When this is
+ the case, they match immediately after and immediately
+ before an internal "\n" character, respectively, in addition
+ to matching at the start and end of the subject string. For
+ example, the pattern /^abc$/ matches the subject string
+ "def\nabc" in multiline mode, but not otherwise. Conse-
+ quently, patterns that are anchored in single line mode
+ because all branches start with "^" are not anchored in mul-
+ tiline mode, and a match for circumflex is possible when the
+ startoffset argument of pcre_exec() is non-zero. The
+ PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is
+ set.
+
+ Note that the sequences \A, \Z, and \z can be used to match
+ the start and end of the subject in both modes, and if all
+ branches of a pattern start with \A it is always anchored,
+ whether PCRE_MULTILINE is set or not.
+
+
+
+FULL STOP (PERIOD, DOT)
+ Outside a character class, a dot in the pattern matches any
+ one character in the subject, including a non-printing char-
+ acter, but not (by default) newline. If the PCRE_DOTALL
+ option is set, dots match newlines as well. The handling of
+ dot is entirely independent of the handling of circumflex
+ and dollar, the only relationship being that they both
+ involve newline characters. Dot has no special meaning in a
+ character class.
+
+
+
+SQUARE BRACKETS
+ An opening square bracket introduces a character class, ter-
+ minated by a closing square bracket. A closing square
+ bracket on its own is not special. If a closing square
+ bracket is required as a member of the class, it should be
+ the first data character in the class (after an initial cir-
+ cumflex, if present) or escaped with a backslash.
+
+ A character class matches a single character in the subject;
+ the character must be in the set of characters defined by
+ the class, unless the first character in the class is a cir-
+ cumflex, in which case the subject character must not be in
+ the set defined by the class. If a circumflex is actually
+ required as a member of the class, ensure it is not the
+ first character, or escape it with a backslash.
+
+ For example, the character class [aeiou] matches any lower
+ case vowel, while [^aeiou] matches any character that is not
+ a lower case vowel. Note that a circumflex is just a con-
+ venient notation for specifying the characters which are in
+ the class by enumerating those that are not. It is not an
+ assertion: it still consumes a character from the subject
+ string, and fails if the current pointer is at the end of
+ the string.
+
+ When caseless matching is set, any letters in a class
+ represent both their upper case and lower case versions, so
+ for example, a caseless [aeiou] matches "A" as well as "a",
+ and a caseless [^aeiou] does not match "A", whereas a case-
+ ful version would.
+
+ The newline character is never treated in any special way in
+ character classes, whatever the setting of the PCRE_DOTALL
+ or PCRE_MULTILINE options is. A class such as [^a] will
+ always match a newline.
+
+ The minus (hyphen) character can be used to specify a range
+ of characters in a character class. For example, [d-m]
+ matches any letter between d and m, inclusive. If a minus
+ character is required in a class, it must be escaped with a
+ backslash or appear in a position where it cannot be inter-
+ preted as indicating a range, typically as the first or last
+ character in the class.
+
+ It is not possible to have the literal character "]" as the
+ end character of a range. A pattern such as [W-]46] is
+ interpreted as a class of two characters ("W" and "-") fol-
+ lowed by a literal string "46]", so it would match "W46]" or
+ "-46]". However, if the "]" is escaped with a backslash it
+ is interpreted as the end of range, so [W-\]46] is inter-
+ preted as a single class containing a range followed by two
+ separate characters. The octal or hexadecimal representation
+ of "]" can also be used to end a range.
+
+ Ranges operate in ASCII collating sequence. They can also be
+ used for characters specified numerically, for example
+ [\000-\037]. If a range that includes letters is used when
+ caseless matching is set, it matches the letters in either
+ case. For example, [W-c] is equivalent to [][\^_`wxyzabc],
+ matched caselessly, and if character tables for the "fr"
+ locale are in use, [\xc8-\xcb] matches accented E characters
+ in both cases.
+
+ The character types \d, \D, \s, \S, \w, and \W may also
+ appear in a character class, and add the characters that
+ they match to the class. For example, [\dABCDEF] matches any
+ hexadecimal digit. A circumflex can conveniently be used
+ with the upper case character types to specify a more res-
+ tricted set of characters than the matching lower case type.
+ For example, the class [^\W_] matches any letter or digit,
+ but not underscore.
+
+ All non-alphameric characters other than \, -, ^ (at the
+ start) and the terminating ] are non-special in character
+ classes, but it does no harm if they are escaped.
+
+
+
+POSIX CHARACTER CLASSES
+ Perl 5.6 (not yet released at the time of writing) is going
+ to support the POSIX notation for character classes, which
+ uses names enclosed by [: and :] within the enclosing
+ square brackets. PCRE supports this notation. For example,
+
+ [01[:alpha:]%]
+
+ matches "0", "1", any alphabetic character, or "%". The sup-
+ ported class names are
+
+ alnum letters and digits
+ alpha letters
+ ascii character codes 0 - 127
+ cntrl control characters
+ digit decimal digits (same as \d)
+ graph printing characters, excluding space
+ lower lower case letters
+ print printing characters, including space
+ punct printing characters, excluding letters and digits
+ space white space (same as \s)
+ upper upper case letters
+ word "word" characters (same as \w)
+ xdigit hexadecimal digits
+
+ The names "ascii" and "word" are Perl extensions. Another
+ Perl extension is negation, which is indicated by a ^ char-
+ acter after the colon. For example,
+
+ [12[:^digit:]]
+
+ matches "1", "2", or any non-digit. PCRE (and Perl) also
+ recognize the POSIX syntax [.ch.] and [=ch=] where "ch" is a
+ "collating element", but these are not supported, and an
+ error is given if they are encountered.
+
+
+
+VERTICAL BAR
+ Vertical bar characters are used to separate alternative
+ patterns. For example, the pattern
+
+ gilbert|sullivan
+
+ matches either "gilbert" or "sullivan". Any number of alter-
+ natives may appear, and an empty alternative is permitted
+ (matching the empty string). The matching process tries
+ each alternative in turn, from left to right, and the first
+ one that succeeds is used. If the alternatives are within a
+ subpattern (defined below), "succeeds" means matching the
+ rest of the main pattern as well as the alternative in the
+ subpattern.
+
+
+
+INTERNAL OPTION SETTING
+ The settings of PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL,
+ and PCRE_EXTENDED can be changed from within the pattern by
+ a sequence of Perl option letters enclosed between "(?" and
+ ")". The option letters are
+
+ i for PCRE_CASELESS
+ m for PCRE_MULTILINE
+ s for PCRE_DOTALL
+ x for PCRE_EXTENDED
+
+ For example, (?im) sets caseless, multiline matching. It is
+ also possible to unset these options by preceding the letter
+ with a hyphen, and a combined setting and unsetting such as
+ (?im-sx), which sets PCRE_CASELESS and PCRE_MULTILINE while
+ unsetting PCRE_DOTALL and PCRE_EXTENDED, is also permitted.
+ If a letter appears both before and after the hyphen, the
+ option is unset.
+
+ The scope of these option changes depends on where in the
+ pattern the setting occurs. For settings that are outside
+ any subpattern (defined below), the effect is the same as if
+ the options were set or unset at the start of matching. The
+ following patterns all behave in exactly the same way:
+
+ (?i)abc
+ a(?i)bc
+ ab(?i)c
+ abc(?i)
+
+ which in turn is the same as compiling the pattern abc with
+ PCRE_CASELESS set. In other words, such "top level" set-
+ tings apply to the whole pattern (unless there are other
+ changes inside subpatterns). If there is more than one set-
+ ting of the same option at top level, the rightmost setting
+ is used.
+
+ If an option change occurs inside a subpattern, the effect
+ is different. This is a change of behaviour in Perl 5.005.
+ An option change inside a subpattern affects only that part
+ of the subpattern that follows it, so
+
+ (a(?i)b)c
+
+ matches abc and aBc and no other strings (assuming
+ PCRE_CASELESS is not used). By this means, options can be
+ made to have different settings in different parts of the
+ pattern. Any changes made in one alternative do carry on
+ into subsequent branches within the same subpattern. For
+ example,
+
+ (a(?i)b|c)
+
+ matches "ab", "aB", "c", and "C", even though when matching
+ "C" the first branch is abandoned before the option setting.
+ This is because the effects of option settings happen at
+ compile time. There would be some very weird behaviour oth-
+ erwise.
+
+ The PCRE-specific options PCRE_UNGREEDY and PCRE_EXTRA can
+ be changed in the same way as the Perl-compatible options by
+ using the characters U and X respectively. The (?X) flag
+ setting is special in that it must always occur earlier in
+ the pattern than any of the additional features it turns on,
+ even when it is at top level. It is best put at the start.
+
+
+
+SUBPATTERNS
+ Subpatterns are delimited by parentheses (round brackets),
+ which can be nested. Marking part of a pattern as a subpat-
+ tern does two things:
+
+ 1. It localizes a set of alternatives. For example, the pat-
+ tern
+
+ cat(aract|erpillar|)
+
+ matches one of the words "cat", "cataract", or "caterpil-
+ lar". Without the parentheses, it would match "cataract",
+ "erpillar" or the empty string.
+
+ 2. It sets up the subpattern as a capturing subpattern (as
+ defined above). When the whole pattern matches, that por-
+ tion of the subject string that matched the subpattern is
+ passed back to the caller via the ovector argument of
+ pcre_exec(). Opening parentheses are counted from left to
+ right (starting from 1) to obtain the numbers of the captur-
+ ing subpatterns.
+
+ For example, if the string "the red king" is matched against
+ the pattern
+
+ the ((red|white) (king|queen))
+
+ the captured substrings are "red king", "red", and "king",
+ and are numbered 1, 2, and 3, respectively.
+
+ The fact that plain parentheses fulfil two functions is not
+ always helpful. There are often times when a grouping sub-
+ pattern is required without a capturing requirement. If an
+ opening parenthesis is followed by "?:", the subpattern does
+ not do any capturing, and is not counted when computing the
+ number of any subsequent capturing subpatterns. For example,
+ if the string "the white queen" is matched against the pat-
+ tern
+
+ the ((?:red|white) (king|queen))
+
+ the captured substrings are "white queen" and "queen", and
+ are numbered 1 and 2. The maximum number of captured sub-
+ strings is 99, and the maximum number of all subpatterns,
+ both capturing and non-capturing, is 200.
+
+ As a convenient shorthand, if any option settings are
+ required at the start of a non-capturing subpattern, the
+ option letters may appear between the "?" and the ":". Thus
+ the two patterns
+
+ (?i:saturday|sunday)
+ (?:(?i)saturday|sunday)
+
+ match exactly the same set of strings. Because alternative
+ branches are tried from left to right, and options are not
+ reset until the end of the subpattern is reached, an option
+ setting in one branch does affect subsequent branches, so
+ the above patterns match "SUNDAY" as well as "Saturday".
+
+
+
+REPETITION
+ Repetition is specified by quantifiers, which can follow any
+ of the following items:
+
+ a single character, possibly escaped
+ the . metacharacter
+ a character class
+ a back reference (see next section)
+ a parenthesized subpattern (unless it is an assertion -
+ see below)
+
+ The general repetition quantifier specifies a minimum and
+ maximum number of permitted matches, by giving the two
+ numbers in curly brackets (braces), separated by a comma.
+ The numbers must be less than 65536, and the first must be
+ less than or equal to the second. For example:
+
+ z{2,4}
+
+ matches "zz", "zzz", or "zzzz". A closing brace on its own
+ is not a special character. If the second number is omitted,
+ but the comma is present, there is no upper limit; if the
+ second number and the comma are both omitted, the quantifier
+ specifies an exact number of required matches. Thus
+
+ [aeiou]{3,}
+
+ matches at least 3 successive vowels, but may match many
+ more, while
+
+ \d{8}
+
+ matches exactly 8 digits. An opening curly bracket that
+ appears in a position where a quantifier is not allowed, or
+ one that does not match the syntax of a quantifier, is taken
+ as a literal character. For example, {,6} is not a quantif-
+ ier, but a literal string of four characters.
+ The quantifier {0} is permitted, causing the expression to
+ behave as if the previous item and the quantifier were not
+ present.
+
+ For convenience (and historical compatibility) the three
+ most common quantifiers have single-character abbreviations:
+
+ * is equivalent to {0,}
+ + is equivalent to {1,}
+ ? is equivalent to {0,1}
+
+ It is possible to construct infinite loops by following a
+ subpattern that can match no characters with a quantifier
+ that has no upper limit, for example:
+
+ (a?)*
+
+ Earlier versions of Perl and PCRE used to give an error at
+ compile time for such patterns. However, because there are
+ cases where this can be useful, such patterns are now
+ accepted, but if any repetition of the subpattern does in
+ fact match no characters, the loop is forcibly broken.
+
+ By default, the quantifiers are "greedy", that is, they
+ match as much as possible (up to the maximum number of per-
+ mitted times), without causing the rest of the pattern to
+ fail. The classic example of where this gives problems is in
+ trying to match comments in C programs. These appear between
+ the sequences /* and */ and within the sequence, individual
+ * and / characters may appear. An attempt to match C com-
+ ments by applying the pattern
+
+ /\*.*\*/
+
+ to the string
+
+ /* first command */ not comment /* second comment */
+
+ fails, because it matches the entire string owing to the
+ greediness of the .* item.
+
+ However, if a quantifier is followed by a question mark, it
+ ceases to be greedy, and instead matches the minimum number
+ of times possible, so the pattern
+
+ /\*.*?\*/
+
+ does the right thing with the C comments. The meaning of the
+ various quantifiers is not otherwise changed, just the pre-
+ ferred number of matches. Do not confuse this use of ques-
+ tion mark with its use as a quantifier in its own right.
+ Because it has two uses, it can sometimes appear doubled, as
+ in
+
+ \d??\d
+
+ which matches one digit by preference, but can match two if
+ that is the only way the rest of the pattern matches.
+
+ If the PCRE_UNGREEDY option is set (an option which is not
+ available in Perl), the quantifiers are not greedy by
+ default, but individual ones can be made greedy by following
+ them with a question mark. In other words, it inverts the
+ default behaviour.
+
+ When a parenthesized subpattern is quantified with a minimum
+ repeat count that is greater than 1 or with a limited max-
+ imum, more store is required for the compiled pattern, in
+ proportion to the size of the minimum or maximum.
+
+ If a pattern starts with .* or .{0,} and the PCRE_DOTALL
+ option (equivalent to Perl's /s) is set, thus allowing the .
+ to match newlines, the pattern is implicitly anchored,
+ because whatever follows will be tried against every charac-
+ ter position in the subject string, so there is no point in
+ retrying the overall match at any position after the first.
+ PCRE treats such a pattern as though it were preceded by \A.
+ In cases where it is known that the subject string contains
+ no newlines, it is worth setting PCRE_DOTALL when the pat-
+ tern begins with .* in order to obtain this optimization, or
+ alternatively using ^ to indicate anchoring explicitly.
+
+ When a capturing subpattern is repeated, the value captured
+ is the substring that matched the final iteration. For exam-
+ ple, after
+
+ (tweedle[dume]{3}\s*)+
+
+ has matched "tweedledum tweedledee" the value of the cap-
+ tured substring is "tweedledee". However, if there are
+ nested capturing subpatterns, the corresponding captured
+ values may have been set in previous iterations. For exam-
+ ple, after
+
+ /(a|(b))+/
+
+ matches "aba" the value of the second captured substring is
+ "b".
+
+
+
+BACK REFERENCES
+ Outside a character class, a backslash followed by a digit
+ greater than 0 (and possibly further digits) is a back
+
+
+
+
+SunOS 5.8 Last change: 30
+
+
+
+ reference to a capturing subpattern earlier (i.e. to its
+ left) in the pattern, provided there have been that many
+ previous capturing left parentheses.
+
+ However, if the decimal number following the backslash is
+ less than 10, it is always taken as a back reference, and
+ causes an error only if there are not that many capturing
+ left parentheses in the entire pattern. In other words, the
+ parentheses that are referenced need not be to the left of
+ the reference for numbers less than 10. See the section
+ entitled "Backslash" above for further details of the han-
+ dling of digits following a backslash.
+
+ A back reference matches whatever actually matched the cap-
+ turing subpattern in the current subject string, rather than
+ anything matching the subpattern itself. So the pattern
+
+ (sens|respons)e and \1ibility
+
+ matches "sense and sensibility" and "response and responsi-
+ bility", but not "sense and responsibility". If caseful
+ matching is in force at the time of the back reference, the
+ case of letters is relevant. For example,
+
+ ((?i)rah)\s+\1
+
+ matches "rah rah" and "RAH RAH", but not "RAH rah", even
+ though the original capturing subpattern is matched case-
+ lessly.
+
+ There may be more than one back reference to the same sub-
+ pattern. If a subpattern has not actually been used in a
+ particular match, any back references to it always fail. For
+ example, the pattern
+
+ (a|(bc))\2
+
+ always fails if it starts to match "a" rather than "bc".
+ Because there may be up to 99 back references, all digits
+ following the backslash are taken as part of a potential
+ back reference number. If the pattern continues with a digit
+ character, some delimiter must be used to terminate the back
+ reference. If the PCRE_EXTENDED option is set, this can be
+ whitespace. Otherwise an empty comment can be used.
+
+ A back reference that occurs inside the parentheses to which
+ it refers fails when the subpattern is first used, so, for
+ example, (a\1) never matches. However, such references can
+ be useful inside repeated subpatterns. For example, the pat-
+ tern
+
+ (a|b\1)+
+
+ matches any number of "a"s and also "aba", "ababbaa" etc. At
+ each iteration of the subpattern, the back reference matches
+ the character string corresponding to the previous itera-
+ tion. In order for this to work, the pattern must be such
+ that the first iteration does not need to match the back
+ reference. This can be done using alternation, as in the
+ example above, or by a quantifier with a minimum of zero.
+
+
+
+ASSERTIONS
+ An assertion is a test on the characters following or
+ preceding the current matching point that does not actually
+ consume any characters. The simple assertions coded as \b,
+ \B, \A, \Z, \z, ^ and $ are described above. More compli-
+ cated assertions are coded as subpatterns. There are two
+ kinds: those that look ahead of the current position in the
+ subject string, and those that look behind it.
+
+ An assertion subpattern is matched in the normal way, except
+ that it does not cause the current matching position to be
+ changed. Lookahead assertions start with (?= for positive
+ assertions and (?! for negative assertions. For example,
+
+ \w+(?=;)
+
+ matches a word followed by a semicolon, but does not include
+ the semicolon in the match, and
+
+ foo(?!bar)
+
+ matches any occurrence of "foo" that is not followed by
+ "bar". Note that the apparently similar pattern
+
+ (?!foo)bar
+
+ does not find an occurrence of "bar" that is preceded by
+ something other than "foo"; it finds any occurrence of "bar"
+ whatsoever, because the assertion (?!foo) is always true
+ when the next three characters are "bar". A lookbehind
+ assertion is needed to achieve this effect.
+
+ Lookbehind assertions start with (?<= for positive asser-
+ tions and (?<! for negative assertions. For example,
+
+ (?<!foo)bar
+
+ does find an occurrence of "bar" that is not preceded by
+ "foo". The contents of a lookbehind assertion are restricted
+ such that all the strings it matches must have a fixed
+ length. However, if there are several alternatives, they do
+ not all have to have the same fixed length. Thus
+
+ (?<=bullock|donkey)
+
+ is permitted, but
+
+ (?<!dogs?|cats?)
+
+ causes an error at compile time. Branches that match dif-
+ ferent length strings are permitted only at the top level of
+ a lookbehind assertion. This is an extension compared with
+ Perl 5.005, which requires all branches to match the same
+ length of string. An assertion such as
+
+ (?<=ab(c|de))
+
+ is not permitted, because its single top-level branch can
+ match two different lengths, but it is acceptable if rewrit-
+ ten to use two top-level branches:
+
+ (?<=abc|abde)
+
+ The implementation of lookbehind assertions is, for each
+ alternative, to temporarily move the current position back
+ by the fixed width and then try to match. If there are
+ insufficient characters before the current position, the
+ match is deemed to fail. Lookbehinds in conjunction with
+ once-only subpatterns can be particularly useful for match-
+ ing at the ends of strings; an example is given at the end
+ of the section on once-only subpatterns.
+
+ Several assertions (of any sort) may occur in succession.
+ For example,
+
+ (?<=\d{3})(?<!999)foo
+
+ matches "foo" preceded by three digits that are not "999".
+ Notice that each of the assertions is applied independently
+ at the same point in the subject string. First there is a
+ check that the previous three characters are all digits, and
+ then there is a check that the same three characters are not
+ "999". This pattern does not match "foo" preceded by six
+ characters, the first of which are digits and the last three
+ of which are not "999". For example, it doesn't match
+ "123abcfoo". A pattern to do that is
+
+ (?<=\d{3}...)(?<!999)foo
+
+ This time the first assertion looks at the preceding six
+ characters, checking that the first three are digits, and
+ then the second assertion checks that the preceding three
+ characters are not "999".
+
+ Assertions can be nested in any combination. For example,
+
+ (?<=(?<!foo)bar)baz
+
+ matches an occurrence of "baz" that is preceded by "bar"
+ which in turn is not preceded by "foo", while
+
+ (?<=\d{3}(?!999)...)foo
+
+ is another pattern which matches "foo" preceded by three
+ digits and any three characters that are not "999".
+
+ Assertion subpatterns are not capturing subpatterns, and may
+ not be repeated, because it makes no sense to assert the
+ same thing several times. If any kind of assertion contains
+ capturing subpatterns within it, these are counted for the
+ purposes of numbering the capturing subpatterns in the whole
+ pattern. However, substring capturing is carried out only
+ for positive assertions, because it does not make sense for
+ negative assertions.
+
+ Assertions count towards the maximum of 200 parenthesized
+ subpatterns.
+
+
+
+ONCE-ONLY SUBPATTERNS
+ With both maximizing and minimizing repetition, failure of
+ what follows normally causes the repeated item to be re-
+ evaluated to see if a different number of repeats allows the
+ rest of the pattern to match. Sometimes it is useful to
+ prevent this, either to change the nature of the match, or
+ to cause it fail earlier than it otherwise might, when the
+ author of the pattern knows there is no point in carrying
+ on.
+
+ Consider, for example, the pattern \d+foo when applied to
+ the subject line
+
+ 123456bar
+
+ After matching all 6 digits and then failing to match "foo",
+ the normal action of the matcher is to try again with only 5
+ digits matching the \d+ item, and then with 4, and so on,
+ before ultimately failing. Once-only subpatterns provide the
+ means for specifying that once a portion of the pattern has
+ matched, it is not to be re-evaluated in this way, so the
+ matcher would give up immediately on failing to match "foo"
+ the first time. The notation is another kind of special
+ parenthesis, starting with (?> as in this example:
+
+ (?>\d+)bar
+
+ This kind of parenthesis "locks up" the part of the pattern
+ it contains once it has matched, and a failure further into
+ the pattern is prevented from backtracking into it. Back-
+ tracking past it to previous items, however, works as nor-
+ mal.
+
+ An alternative description is that a subpattern of this type
+ matches the string of characters that an identical stan-
+ dalone pattern would match, if anchored at the current point
+ in the subject string.
+
+ Once-only subpatterns are not capturing subpatterns. Simple
+ cases such as the above example can be thought of as a max-
+ imizing repeat that must swallow everything it can. So,
+ while both \d+ and \d+? are prepared to adjust the number of
+ digits they match in order to make the rest of the pattern
+ match, (?>\d+) can only match an entire sequence of digits.
+
+ This construction can of course contain arbitrarily compli-
+ cated subpatterns, and it can be nested.
+
+ Once-only subpatterns can be used in conjunction with look-
+ behind assertions to specify efficient matching at the end
+ of the subject string. Consider a simple pattern such as
+
+ abcd$
+
+ when applied to a long string which does not match. Because
+ matching proceeds from left to right, PCRE will look for
+ each "a" in the subject and then see if what follows matches
+ the rest of the pattern. If the pattern is specified as
+
+ ^.*abcd$
+
+ the initial .* matches the entire string at first, but when
+ this fails (because there is no following "a"), it back-
+ tracks to match all but the last character, then all but the
+ last two characters, and so on. Once again the search for
+ "a" covers the entire string, from right to left, so we are
+ no better off. However, if the pattern is written as
+
+ ^(?>.*)(?<=abcd)
+
+ there can be no backtracking for the .* item; it can match
+ only the entire string. The subsequent lookbehind assertion
+ does a single test on the last four characters. If it fails,
+ the match fails immediately. For long strings, this approach
+ makes a significant difference to the processing time.
+
+ When a pattern contains an unlimited repeat inside a subpat-
+ tern that can itself be repeated an unlimited number of
+ times, the use of a once-only subpattern is the only way to
+ avoid some failing matches taking a very long time indeed.
+ The pattern
+
+ (\D+|<\d+>)*[!?]
+
+ matches an unlimited number of substrings that either con-
+ sist of non-digits, or digits enclosed in <>, followed by
+ either ! or ?. When it matches, it runs quickly. However, if
+ it is applied to
+
+ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+
+ it takes a long time before reporting failure. This is
+ because the string can be divided between the two repeats in
+ a large number of ways, and all have to be tried. (The exam-
+ ple used [!?] rather than a single character at the end,
+ because both PCRE and Perl have an optimization that allows
+ for fast failure when a single character is used. They
+ remember the last single character that is required for a
+ match, and fail early if it is not present in the string.)
+ If the pattern is changed to
+
+ ((?>\D+)|<\d+>)*[!?]
+
+ sequences of non-digits cannot be broken, and failure hap-
+ pens quickly.
+
+
+
+CONDITIONAL SUBPATTERNS
+ It is possible to cause the matching process to obey a sub-
+ pattern conditionally or to choose between two alternative
+ subpatterns, depending on the result of an assertion, or
+ whether a previous capturing subpattern matched or not. The
+ two possible forms of conditional subpattern are
+
+ (?(condition)yes-pattern)
+ (?(condition)yes-pattern|no-pattern)
+
+ If the condition is satisfied, the yes-pattern is used; oth-
+ erwise the no-pattern (if present) is used. If there are
+ more than two alternatives in the subpattern, a compile-time
+ error occurs.
+
+ There are two kinds of condition. If the text between the
+ parentheses consists of a sequence of digits, the condition
+ is satisfied if the capturing subpattern of that number has
+ previously matched. The number must be greater than zero.
+ Consider the following pattern, which contains non-
+ significant white space to make it more readable (assume the
+ PCRE_EXTENDED option) and to divide it into three parts for
+ ease of discussion:
+
+ ( \( )? [^()]+ (?(1) \) )
+
+ The first part matches an optional opening parenthesis, and
+ if that character is present, sets it as the first captured
+ substring. The second part matches one or more characters
+ that are not parentheses. The third part is a conditional
+ subpattern that tests whether the first set of parentheses
+ matched or not. If they did, that is, if subject started
+ with an opening parenthesis, the condition is true, and so
+ the yes-pattern is executed and a closing parenthesis is
+ required. Otherwise, since no-pattern is not present, the
+ subpattern matches nothing. In other words, this pattern
+ matches a sequence of non-parentheses, optionally enclosed
+ in parentheses.
+
+ If the condition is not a sequence of digits, it must be an
+ assertion. This may be a positive or negative lookahead or
+ lookbehind assertion. Consider this pattern, again contain-
+ ing non-significant white space, and with the two alterna-
+ tives on the second line:
+
+ (?(?=[^a-z]*[a-z])
+ \d{2}-[a-z]{3}-\d{2} | \d{2}-\d{2}-\d{2} )
+
+ The condition is a positive lookahead assertion that matches
+ an optional sequence of non-letters followed by a letter. In
+ other words, it tests for the presence of at least one
+ letter in the subject. If a letter is found, the subject is
+ matched against the first alternative; otherwise it is
+ matched against the second. This pattern matches strings in
+ one of the two forms dd-aaa-dd or dd-dd-dd, where aaa are
+ letters and dd are digits.
+
+
+
+COMMENTS
+ The sequence (?# marks the start of a comment which contin-
+ ues up to the next closing parenthesis. Nested parentheses
+ are not permitted. The characters that make up a comment
+ play no part in the pattern matching at all.
+
+ If the PCRE_EXTENDED option is set, an unescaped # character
+ outside a character class introduces a comment that contin-
+ ues up to the next newline character in the pattern.
+
+
+
+RECURSIVE PATTERNS
+ Consider the problem of matching a string in parentheses,
+ allowing for unlimited nested parentheses. Without the use
+ of recursion, the best that can be done is to use a pattern
+ that matches up to some fixed depth of nesting. It is not
+ possible to handle an arbitrary nesting depth. Perl 5.6 has
+ provided an experimental facility that allows regular
+ expressions to recurse (amongst other things). It does this
+ by interpolating Perl code in the expression at run time,
+ and the code can refer to the expression itself. A Perl pat-
+ tern to solve the parentheses problem can be created like
+ this:
+
+ $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;
+
+ The (?p{...}) item interpolates Perl code at run time, and
+ in this case refers recursively to the pattern in which it
+ appears. Obviously, PCRE cannot support the interpolation of
+ Perl code. Instead, the special item (?R) is provided for
+ the specific case of recursion. This PCRE pattern solves the
+ parentheses problem (assume the PCRE_EXTENDED option is set
+ so that white space is ignored):
+
+ \( ( (?>[^()]+) | (?R) )* \)
+
+ First it matches an opening parenthesis. Then it matches any
+ number of substrings which can either be a sequence of non-
+ parentheses, or a recursive match of the pattern itself
+ (i.e. a correctly parenthesized substring). Finally there is
+ a closing parenthesis.
+
+ This particular example pattern contains nested unlimited
+ repeats, and so the use of a once-only subpattern for match-
+ ing strings of non-parentheses is important when applying
+ the pattern to strings that do not match. For example, when
+ it is applied to
+
+ (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+
+ it yields "no match" quickly. However, if a once-only sub-
+ pattern is not used, the match runs for a very long time
+ indeed because there are so many different ways the + and *
+ repeats can carve up the subject, and all have to be tested
+ before failure can be reported.
+
+ The values set for any capturing subpatterns are those from
+ the outermost level of the recursion at which the subpattern
+ value is set. If the pattern above is matched against
+
+ (ab(cd)ef)
+
+ the value for the capturing parentheses is "ef", which is
+ the last value taken on at the top level. If additional
+ parentheses are added, giving
+
+ \( ( ( (?>[^()]+) | (?R) )* ) \)
+ ^ ^
+ ^ ^ the string they capture is
+ "ab(cd)ef", the contents of the top level parentheses. If
+ there are more than 15 capturing parentheses in a pattern,
+ PCRE has to obtain extra memory to store data during a
+ recursion, which it does by using pcre_malloc, freeing it
+ via pcre_free afterwards. If no memory can be obtained, it
+ saves data for the first 15 capturing parentheses only, as
+ there is no way to give an out-of-memory error from within a
+ recursion.
+
+
+
+PERFORMANCE
+ Certain items that may appear in patterns are more efficient
+ than others. It is more efficient to use a character class
+ like [aeiou] than a set of alternatives such as (a|e|i|o|u).
+ In general, the simplest construction that provides the
+ required behaviour is usually the most efficient. Jeffrey
+ Friedl's book contains a lot of discussion about optimizing
+ regular expressions for efficient performance.
+
+ When a pattern begins with .* and the PCRE_DOTALL option is
+ set, the pattern is implicitly anchored by PCRE, since it
+ can match only at the start of a subject string. However, if
+ PCRE_DOTALL is not set, PCRE cannot make this optimization,
+ because the . metacharacter does not then match a newline,
+ and if the subject string contains newlines, the pattern may
+ match from the character immediately following one of them
+ instead of from the very start. For example, the pattern
+
+ (.*) second
+
+ matches the subject "first\nand second" (where \n stands for
+ a newline character) with the first captured substring being
+ "and". In order to do this, PCRE has to retry the match
+ starting after every newline in the subject.
+
+ If you are using such a pattern with subject strings that do
+ not contain newlines, the best performance is obtained by
+ setting PCRE_DOTALL, or starting the pattern with ^.* to
+ indicate explicit anchoring. That saves PCRE from having to
+ scan along the subject looking for a newline to restart at.
+
+ Beware of patterns that contain nested indefinite repeats.
+ These can take a long time to run when applied to a string
+ that does not match. Consider the pattern fragment
+
+ (a+)*
+
+ This can match "aaaa" in 33 different ways, and this number
+ increases very rapidly as the string gets longer. (The *
+ repeat can match 0, 1, 2, 3, or 4 times, and for each of
+ those cases other than 0, the + repeats can match different
+ numbers of times.) When the remainder of the pattern is such
+ that the entire match is going to fail, PCRE has in princi-
+ ple to try every possible variation, and this can take an
+ extremely long time.
+
+ An optimization catches some of the more simple cases such
+ as
+
+ (a+)*b
+
+ where a literal character follows. Before embarking on the
+ standard matching procedure, PCRE checks that there is a "b"
+ later in the subject string, and if there is not, it fails
+ the match immediately. However, when there is no following
+ literal this optimization cannot be used. You can see the
+ difference by comparing the behaviour of
+
+ (a+)*\d
+
+ with the pattern above. The former gives a failure almost
+ instantly when applied to a whole line of "a" characters,
+ whereas the latter takes an appreciable time with strings
+ longer than about 20 characters.
+
+
+
+UTF-8 SUPPORT
+ Starting at release 3.3, PCRE has some support for character
+ strings encoded in the UTF-8 format. This is incomplete, and
+ is regarded as experimental. In order to use it, you must
+ configure PCRE to include UTF-8 support in the code, and, in
+ addition, you must call pcre_compile() with the PCRE_UTF8
+ option flag. When you do this, both the pattern and any sub-
+ ject strings that are matched against it are treated as
+ UTF-8 strings instead of just strings of bytes, but only in
+ the cases that are mentioned below.
+
+ If you compile PCRE with UTF-8 support, but do not use it at
+ run time, the library will be a bit bigger, but the addi-
+ tional run time overhead is limited to testing the PCRE_UTF8
+ flag in several places, so should not be very large.
+
+ PCRE assumes that the strings it is given contain valid
+ UTF-8 codes. It does not diagnose invalid UTF-8 strings. If
+ you pass invalid UTF-8 strings to PCRE, the results are
+ undefined.
+
+ Running with PCRE_UTF8 set causes these changes in the way
+ PCRE works:
+
+ 1. In a pattern, the escape sequence \x{...}, where the
+ contents of the braces is a string of hexadecimal digits, is
+ interpreted as a UTF-8 character whose code number is the
+ given hexadecimal number, for example: \x{1234}. This
+ inserts from one to six literal bytes into the pattern,
+ using the UTF-8 encoding. If a non-hexadecimal digit appears
+ between the braces, the item is not recognized.
+
+ 2. The original hexadecimal escape sequence, \xhh, generates
+ a two-byte UTF-8 character if its value is greater than 127.
+
+ 3. Repeat quantifiers are NOT correctly handled if they fol-
+ low a multibyte character. For example, \x{100}* and \xc3+
+ do not work. If you want to repeat such characters, you must
+ enclose them in non-capturing parentheses, for example
+ (?:\x{100}), at present.
+
+ 4. The dot metacharacter matches one UTF-8 character instead
+ of a single byte.
+
+ 5. Unlike literal UTF-8 characters, the dot metacharacter
+ followed by a repeat quantifier does operate correctly on
+ UTF-8 characters instead of single bytes.
+
+ 4. Although the \x{...} escape is permitted in a character
+ class, characters whose values are greater than 255 cannot
+ be included in a class.
+
+ 5. A class is matched against a UTF-8 character instead of
+ just a single byte, but it can match only characters whose
+ values are less than 256. Characters with greater values
+ always fail to match a class.
+
+ 6. Repeated classes work correctly on multiple characters.
+
+ 7. Classes containing just a single character whose value is
+ greater than 127 (but less than 256), for example, [\x80] or
+ [^\x{93}], do not work because these are optimized into sin-
+ gle byte matches. In the first case, of course, the class
+ brackets are just redundant.
+
+ 8. Lookbehind assertions move backwards in the subject by a
+ fixed number of characters instead of a fixed number of
+ bytes. Simple cases have been tested to work correctly, but
+ there may be hidden gotchas herein.
+
+ 9. The character types such as \d and \w do not work
+ correctly with UTF-8 characters. They continue to test a
+ single byte.
+
+ 10. Anything not explicitly mentioned here continues to work
+ in bytes rather than in characters.
+
+ The following UTF-8 features of Perl 5.6 are not imple-
+ mented:
+
+ 1. The escape sequence \C to match a single byte.
+
+ 2. The use of Unicode tables and properties and escapes \p,
+ \P, and \X.
+
+
+
+SAMPLE PROGRAM
+ The code below is a simple, complete demonstration program,
+ to get you started with using PCRE. This code is also sup-
+ plied in the file pcredemo.c in the PCRE distribution.
+
+ The program compiles the regular expression that is its
+ first argument, and matches it against the subject string in
+ its second argument. No options are set, and default charac-
+ ter tables are used. If matching succeeds, the program out-
+ puts the portion of the subject that matched, together with
+ the contents of any captured substrings.
+
+ On a Unix system that has PCRE installed in /usr/local, you
+ can compile the demonstration program using a command like
+ this:
+
+ gcc -o pcredemo pcredemo.c -I/usr/local/include
+ -L/usr/local/lib -lpcre
+
+ Then you can run simple tests like this:
+
+ ./pcredemo 'cat|dog' 'the cat sat on the mat'
+
+ Note that there is a much more comprehensive test program,
+ called pcretest, which supports many more facilities for
+ testing regular expressions. The pcredemo program is pro-
+ vided as a simple coding example.
+
+ On some operating systems (e.g. Solaris) you may get an
+ error like this when you try to run pcredemo:
+
+ ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such
+ file or directory
+
+ This is caused by the way shared library support works on
+ those systems. You need to add
+
+ -R/usr/local/lib
+
+ to the compile command to get round this problem. Here's the
+ code:
+
+ #include <stdio.h>
+ #include <string.h>
+ #include <pcre.h>
+
+ #define OVECCOUNT 30 /* should be a multiple of 3 */
+
+ int main(int argc, char **argv)
+ {
+ pcre *re;
+ const char *error;
+ int erroffset;
+ int ovector[OVECCOUNT];
+ int rc, i;
+
+ if (argc != 3)
+ {
+ printf("Two arguments required: a regex and a "
+ "subject string\n");
+ return 1;
+ }
+
+ /* Compile the regular expression in the first argument */
+
+ re = pcre_compile(
+ argv[1], /* the pattern */
+ 0, /* default options */
+ &error, /* for error message */
+ &erroffset, /* for error offset */
+ NULL); /* use default character tables */
+
+ /* Compilation failed: print the error message and exit */
+
+ if (re == NULL)
+ {
+ printf("PCRE compilation failed at offset %d: %s\n",
+ erroffset, error);
+ return 1;
+ }
+
+ /* Compilation succeeded: match the subject in the second
+ argument */
+
+ rc = pcre_exec(
+ re, /* the compiled pattern */
+ NULL, /* we didn't study the pattern */
+ argv[2], /* the subject string */
+ (int)strlen(argv[2]), /* the length of the subject */
+ 0, /* start at offset 0 in the subject */
+ 0, /* default options */
+ ovector, /* vector for substring information */
+ OVECCOUNT); /* number of elements in the vector */
+
+ /* Matching failed: handle error cases */
+
+ if (rc < 0)
+ {
+ switch(rc)
+ {
+ case PCRE_ERROR_NOMATCH: printf("No match\n"); break;
+ /*
+ Handle other special cases if you like
+ */
+ default: printf("Matching error %d\n", rc); break;
+ }
+ return 1;
+ }
+
+ /* Match succeded */
+
+ printf("Match succeeded\n");
+
+ /* The output vector wasn't big enough */
+
+ if (rc == 0)
+ {
+ rc = OVECCOUNT/3;
+ printf("ovector only has room for %d captured "
+ substrings\n", rc - 1);
+ }
+
+ /* Show substrings stored in the output vector */
+
+ for (i = 0; i < rc; i++)
+ {
+ char *substring_start = argv[2] + ovector[2*i];
+ int substring_length = ovector[2*i+1] - ovector[2*i];
+ printf("%2d: %.*s\n", i, substring_length,
+ substring_start);
+ }
+
+ return 0;
+ }

+.TH PCREGREP 1
+.SH NAME
+pcregrep - a grep with Perl-compatible regular expressions.
+.SH SYNOPSIS
+.B pcregrep [-Vcfhilnrsvx] pattern [file] ...
+
+
+.SH DESCRIPTION
+\fBpcregrep\fR searches files for character patterns, in the same way as other
+grep commands do, but it uses the PCRE regular expression library to support
+patterns that are compatible with the regular expressions of Perl 5. See
+\fBpcre(3)\fR for a full description of syntax and semantics.
+
+If no files are specified, \fBpcregrep\fR reads the standard input. By default,
+each line that matches the pattern is copied to the standard output, and if
+there is more than one file, the file name is printed before each line of
+output. However, there are options that can change how \fBpcregrep\fR behaves.
+
+Lines are limited to BUFSIZ characters. BUFSIZ is defined in \fB<stdio.h>\fR.
+The newline character is removed from the end of each line before it is matched
+against the pattern.
+
+
+.SH OPTIONS
+.TP 10
+\fB-V\fR
+Write the version number of the PCRE library being used to the standard error
+stream.
+.TP
+\fB-c\fR
+Do not print individual lines; instead just print a count of the number of
+lines that would otherwise have been printed. If several files are given, a
+count is printed for each of them.
+.TP
+\fB-f\fIfilename\fR
+Read patterns from the file, one per line, and match all patterns against each
+line. There is a maximum of 100 patterns. Trailing white space is removed, and
+blank lines are ignored. An empty file contains no patterns and therefore
+matches nothing.
+.TP
+\fB-h\fR
+Suppress printing of filenames when searching multiple files.
+.TP
+\fB-i\fR
+Ignore upper/lower case distinctions during comparisons.
+.TP
+\fB-l\fR
+Instead of printing lines from the files, just print the names of the files
+containing lines that would have been printed. Each file name is printed
+once, on a separate line.
+.TP
+\fB-n\fR
+Precede each line by its line number in the file.
+.TP
+\fB-r\fR
+If any file is a directory, recursively scan the files it contains. Without
+\fB-r\fR a directory is scanned as a normal file.
+.TP
+\fB-s\fR
+Work silently, that is, display nothing except error messages.
+The exit status indicates whether any matches were found.
+.TP
+\fB-v\fR
+Invert the sense of the match, so that lines which do \fInot\fR match the
+pattern are now the ones that are found.
+.TP
+\fB-x\fR
+Force the pattern to be anchored (it must start matching at the beginning of
+the line) and in addition, require it to match the entire line. This is
+equivalent to having ^ and $ characters at the start and end of each
+alternative branch in the regular expression.
+
+
+.SH SEE ALSO
+\fBpcre(3)\fR, Perl 5 documentation
+
+
+.SH DIAGNOSTICS
+Exit status is 0 if any matches were found, 1 if no matches were found, and 2
+for syntax errors or inacessible files (even if matches were found).

+
+
+.SH DESCRIPTION
+This set of functions provides a POSIX-style API to the PCRE regular expression
+package. See the \fBpcre\fR documentation for a description of the native API,
+which contains additional functionality.
+
+The functions described here are just wrapper functions that ultimately call
+the native API. Their prototypes are defined in the \fBpcreposix.h\fR header
+file, and on Unix systems the library itself is called \fBpcreposix.a\fR, so
+can be accessed by adding \fB-lpcreposix\fR to the command for linking an
+application which uses them. Because the POSIX functions call the native ones,
+it is also necessary to add \fR-lpcre\fR.
+
+I have implemented only those option bits that can be reasonably mapped to PCRE
+native options. In addition, the options REG_EXTENDED and REG_NOSUB are defined
+with the value zero. They have no effect, but since programs that are written
+to the POSIX interface often use them, this makes it easier to slot in PCRE as
+a replacement library. Other POSIX options are not even defined.
+
+When PCRE is called via these functions, it is only the API that is POSIX-like
+in style. The syntax and semantics of the regular expressions themselves are
+still those of Perl, subject to the setting of various PCRE options, as
+described below.
+
+The header for these functions is supplied as \fBpcreposix.h\fR to avoid any
+potential clash with other POSIX libraries. It can, of course, be renamed or
+aliased as \fBregex.h\fR, which is the "correct" name. It provides two
+structure types, \fIregex_t\fR for compiled internal forms, and
+\fIregmatch_t\fR for returning captured substrings. It also defines some
+constants whose names start with "REG_"; these are used for setting options and
+identifying error codes.
+
+
+.SH COMPILING A PATTERN
+
+The function \fBregcomp()\fR is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument \fIpattern\fR. The \fIpreg\fR argument is a pointer
+to a regex_t structure which is used as a base for storing information about
+the compiled expression.
+
+The argument \fIcflags\fR is either zero, or contains one or more of the bits
+defined by the following macros:
+
+ REG_ICASE
+
+The PCRE_CASELESS option is set when the expression is passed for compilation
+to the native function.
+
+ REG_NEWLINE
+
+The PCRE_MULTILINE option is set when the expression is passed for compilation
+to the native function.
+
+In the absence of these flags, no options are passed to the native function.
+This means the the regex is compiled with PCRE default semantics. In
+particular, the way it handles newline characters in the subject string is the
+Perl way, not the POSIX way. Note that setting PCRE_MULTILINE has only
+\fIsome\fR of the effects specified for REG_NEWLINE. It does not affect the way
+newlines are matched by . (they aren't) or a negative class such as [^a] (they
+are).
+
+The yield of \fBregcomp()\fR is zero on success, and non-zero otherwise. The
+\fIpreg\fR structure is filled in on success, and one member of the structure
+is publicized: \fIre_nsub\fR contains the number of capturing subpatterns in
+the regular expression. Various error codes are defined in the header file.
+
+
+.SH MATCHING A PATTERN
+The function \fBregexec()\fR is called to match a pre-compiled pattern
+\fIpreg\fR against a given \fIstring\fR, which is terminated by a zero byte,
+subject to the options in \fIeflags\fR. These can be:
+
+ REG_NOTBOL
+
+The PCRE_NOTBOL option is set when calling the underlying PCRE matching
+function.
+
+ REG_NOTEOL
+
+The PCRE_NOTEOL option is set when calling the underlying PCRE matching
+function.
+
+The portion of the string that was matched, and also any captured substrings,
+are returned via the \fIpmatch\fR argument, which points to an array of
+\fInmatch\fR structures of type \fIregmatch_t\fR, containing the members
+\fIrm_so\fR and \fIrm_eo\fR. These contain the offset to the first character of
+each substring and the offset to the first character after the end of each
+substring, respectively. The 0th element of the vector relates to the entire
+portion of \fIstring\fR that was matched; subsequent elements relate to the
+capturing subpatterns of the regular expression. Unused entries in the array
+have both structure members set to -1.
+
+A successful match yields a zero return; various error codes are defined in the
+header file, of which REG_NOMATCH is the "expected" failure code.
+
+
+.SH ERROR MESSAGES
+The \fBregerror()\fR function maps a non-zero errorcode from either
+\fBregcomp\fR or \fBregexec\fR to a printable message. If \fIpreg\fR is not
+NULL, the error should have arisen from the use of that structure. A message
+terminated by a binary zero is placed in \fIerrbuf\fR. The length of the
+message, including the zero, is limited to \fIerrbuf_size\fR. The yield of the
+function is the size of buffer needed to hold the whole message.
+
+
+.SH STORAGE
+Compiling a regular expression causes memory to be allocated and associated
+with the \fIpreg\fR structure. The function \fBregfree()\fR frees all such
+memory, after which \fIpreg\fR may no longer be used as a compiled expression.

+<P>
+This set of functions provides a POSIX-style API to the PCRE regular expression
+package. See the <B>pcre</B> documentation for a description of the native API,
+which contains additional functionality.
+</P>
+<P>
+The functions described here are just wrapper functions that ultimately call
+the native API. Their prototypes are defined in the <B>pcreposix.h</B> header
+file, and on Unix systems the library itself is called <B>pcreposix.a</B>, so
+can be accessed by adding <B>-lpcreposix</B> to the command for linking an
+application which uses them. Because the POSIX functions call the native ones,
+it is also necessary to add \fR-lpcre\fR.
+</P>
+<P>
+I have implemented only those option bits that can be reasonably mapped to PCRE
+native options. In addition, the options REG_EXTENDED and REG_NOSUB are defined
+with the value zero. They have no effect, but since programs that are written
+to the POSIX interface often use them, this makes it easier to slot in PCRE as
+a replacement library. Other POSIX options are not even defined.
+</P>
+<P>
+When PCRE is called via these functions, it is only the API that is POSIX-like
+in style. The syntax and semantics of the regular expressions themselves are
+still those of Perl, subject to the setting of various PCRE options, as
+described below.
+</P>
+<P>
+The header for these functions is supplied as <B>pcreposix.h</B> to avoid any
+potential clash with other POSIX libraries. It can, of course, be renamed or
+aliased as <B>regex.h</B>, which is the "correct" name. It provides two
+structure types, <I>regex_t</I> for compiled internal forms, and
+<I>regmatch_t</I> for returning captured substrings. It also defines some
+constants whose names start with "REG_"; these are used for setting options and
+identifying error codes.
+</P>
+<LI><A NAME="SEC4" HREF="#TOC1">COMPILING A PATTERN</A>
+<P>
+The function <B>regcomp()</B> is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument <I>pattern</I>. The <I>preg</I> argument is a pointer
+to a regex_t structure which is used as a base for storing information about
+the compiled expression.
+</P>
+<P>
+The argument <I>cflags</I> is either zero, or contains one or more of the bits
+defined by the following macros:
+</P>
+<P>
+<PRE>
+ REG_ICASE
+</PRE>
+</P>
+<P>
+The PCRE_CASELESS option is set when the expression is passed for compilation
+to the native function.

+<P>
+<PRE>
+ REG_NEWLINE
+</PRE>
+</P>
+<P>
+The PCRE_MULTILINE option is set when the expression is passed for compilation
+to the native function.
+</P>
+<P>
+In the absence of these flags, no options are passed to the native function.
+This means the the regex is compiled with PCRE default semantics. In
+particular, the way it handles newline characters in the subject string is the
+Perl way, not the POSIX way. Note that setting PCRE_MULTILINE has only
+<I>some</I> of the effects specified for REG_NEWLINE. It does not affect the way
+newlines are matched by . (they aren't) or a negative class such as [^a] (they
+are).
+</P>
+<P>
+The yield of <B>regcomp()</B> is zero on success, and non-zero otherwise. The
+<I>preg</I> structure is filled in on success, and one member of the structure
+is publicized: <I>re_nsub</I> contains the number of capturing subpatterns in
+the regular expression. Various error codes are defined in the header file.

+DESCRIPTION
+ This set of functions provides a POSIX-style API to the PCRE
+ regular expression package. See the pcre documentation for a
+ description of the native API, which contains additional
+ functionality.
+
+ The functions described here are just wrapper functions that
+ ultimately call the native API. Their prototypes are defined
+ in the pcreposix.h header file, and on Unix systems the
+ library itself is called pcreposix.a, so can be accessed by
+ adding -lpcreposix to the command for linking an application
+ which uses them. Because the POSIX functions call the native
+ ones, it is also necessary to add -lpcre.
+
+ I have implemented only those option bits that can be rea-
+ sonably mapped to PCRE native options. In addition, the
+ options REG_EXTENDED and REG_NOSUB are defined with the
+ value zero. They have no effect, but since programs that are
+ written to the POSIX interface often use them, this makes it
+ easier to slot in PCRE as a replacement library. Other POSIX
+ options are not even defined.
+
+ When PCRE is called via these functions, it is only the API
+ that is POSIX-like in style. The syntax and semantics of the
+ regular expressions themselves are still those of Perl, sub-
+ ject to the setting of various PCRE options, as described
+ below.
+
+ The header for these functions is supplied as pcreposix.h to
+ avoid any potential clash with other POSIX libraries. It
+ can, of course, be renamed or aliased as regex.h, which is
+ the "correct" name. It provides two structure types, regex_t
+ for compiled internal forms, and regmatch_t for returning
+ captured substrings. It also defines some constants whose
+ names start with "REG_"; these are used for setting options
+ and identifying error codes.
+
+
+
+COMPILING A PATTERN
+ The function regcomp() is called to compile a pattern into
+ an internal form. The pattern is a C string terminated by a
+ binary zero, and is passed in the argument pattern. The preg
+ argument is a pointer to a regex_t structure which is used
+ as a base for storing information about the compiled expres-
+ sion.
+
+ The argument cflags is either zero, or contains one or more
+ of the bits defined by the following macros:
+
+ REG_ICASE
+
+ The PCRE_CASELESS option is set when the expression is
+ passed for compilation to the native function.
+
+ REG_NEWLINE
+
+ The PCRE_MULTILINE option is set when the expression is
+ passed for compilation to the native function.
+
+ In the absence of these flags, no options are passed to the
+ native function. This means the the regex is compiled with
+ PCRE default semantics. In particular, the way it handles
+ newline characters in the subject string is the Perl way,
+ not the POSIX way. Note that setting PCRE_MULTILINE has only
+ some of the effects specified for REG_NEWLINE. It does not
+ affect the way newlines are matched by . (they aren't) or a
+ negative class such as [^a] (they are).
+
+ The yield of regcomp() is zero on success, and non-zero oth-
+ erwise. The preg structure is filled in on success, and one
+ member of the structure is publicized: re_nsub contains the
+ number of capturing subpatterns in the regular expression.
+ Various error codes are defined in the header file.
+
+
+
+MATCHING A PATTERN
+ The function regexec() is called to match a pre-compiled
+ pattern preg against a given string, which is terminated by
+ a zero byte, subject to the options in eflags. These can be:
+
+ REG_NOTBOL
+
+ The PCRE_NOTBOL option is set when calling the underlying
+ PCRE matching function.
+
+ REG_NOTEOL
+
+ The PCRE_NOTEOL option is set when calling the underlying
+ PCRE matching function.
+
+ The portion of the string that was matched, and also any
+ captured substrings, are returned via the pmatch argument,
+ which points to an array of nmatch structures of type
+ regmatch_t, containing the members rm_so and rm_eo. These
+ contain the offset to the first character of each substring
+ and the offset to the first character after the end of each
+ substring, respectively. The 0th element of the vector
+ relates to the entire portion of string that was matched;
+ subsequent elements relate to the capturing subpatterns of
+ the regular expression. Unused entries in the array have
+ both structure members set to -1.
+
+ A successful match yields a zero return; various error codes
+ are defined in the header file, of which REG_NOMATCH is the
+ "expected" failure code.
+
+
+
+ERROR MESSAGES
+ The regerror() function maps a non-zero errorcode from
+ either regcomp or regexec to a printable message. If preg is
+ not NULL, the error should have arisen from the use of that
+ structure. A message terminated by a binary zero is placed
+ in errbuf. The length of the message, including the zero, is
+ limited to errbuf_size. The yield of the function is the
+ size of buffer needed to hold the whole message.
+
+
+
+STORAGE
+ Compiling a regular expression causes memory to be allocated
+ and associated with the preg structure. The function reg-
+ free() frees all such memory, after which preg may no longer
+ be used as a compiled expression.

+.TH PCRETEST 1
+.SH NAME
+pcretest - a program for testing Perl-compatible regular expressions.
+.SH SYNOPSIS
+.B pcretest "[-d] [-i] [-m] [-o osize] [-p] [-t] [source] [destination]"
+
+\fBpcretest\fR was written as a test program for the PCRE regular expression
+library itself, but it can also be used for experimenting with regular
+expressions. This man page describes the features of the test program; for
+details of the regular expressions themselves, see the \fBpcre\fR man page.
+
+.SH OPTIONS
+.TP 10
+\fB-d\fR
+Behave as if each regex had the \fB/D\fR modifier (see below); the internal
+form is output after compilation.
+.TP 10
+\fB-i\fR
+Behave as if each regex had the \fB/I\fR modifier; information about the
+compiled pattern is given after compilation.
+.TP 10
+\fB-m\fR
+Output the size of each compiled pattern after it has been compiled. This is
+equivalent to adding /M to each regular expression. For compatibility with
+earlier versions of pcretest, \fB-s\fR is a synonym for \fB-m\fR.
+.TP 10
+\fB-o\fR \fIosize\fR
+Set the number of elements in the output vector that is used when calling PCRE
+to be \fIosize\fR. The default value is 45, which is enough for 14 capturing
+subexpressions. The vector size can be changed for individual matching calls by
+including \\O in the data line (see below).
+.TP 10
+\fB-p\fR
+Behave as if each regex has \fB/P\fR modifier; the POSIX wrapper API is used
+to call PCRE. None of the other options has any effect when \fB-p\fR is set.
+.TP 10
+\fB-t\fR
+Run each compile, study, and match 20000 times with a timer, and output
+resulting time per compile or match (in milliseconds). Do not set \fB-t\fR with
+\fB-m\fR, because you will then get the size output 20000 times and the timing
+will be distorted.
+
+
+.SH DESCRIPTION
+
+If \fBpcretest\fR is given two filename arguments, it reads from the first and
+writes to the second. If it is given only one filename argument, it reads from
+that file and writes to stdout. Otherwise, it reads from stdin and writes to
+stdout, and prompts for each line of input, using "re>" to prompt for regular
+expressions, and "data>" to prompt for data lines.
+
+The program handles any number of sets of input on a single input file. Each
+set starts with a regular expression, and continues with any number of data
+lines to be matched against the pattern. An empty line signals the end of the
+data lines, at which point a new regular expression is read. The regular
+expressions are given enclosed in any non-alphameric delimiters other than
+backslash, for example
+
+ /(a|bc)x+yz/
+
+White space before the initial delimiter is ignored. A regular expression may
+be continued over several input lines, in which case the newline characters are
+included within it. It is possible to include the delimiter within the pattern
+by escaping it, for example
+
+ /abc\\/def/
+
+If you do so, the escape and the delimiter form part of the pattern, but since
+delimiters are always non-alphameric, this does not affect its interpretation.
+If the terminating delimiter is immediately followed by a backslash, for
+example,
+
+ /abc/\\
+
+then a backslash is added to the end of the pattern. This is done to provide a
+way of testing the error condition that arises if a pattern finishes with a
+backslash, because
+
+ /abc\\/
+
+is interpreted as the first line of a pattern that starts with "abc/", causing
+pcretest to read the next line as a continuation of the regular expression.
+
+
+.SH PATTERN MODIFIERS
+
+The pattern may be followed by \fBi\fR, \fBm\fR, \fBs\fR, or \fBx\fR to set the
+PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, or PCRE_EXTENDED options,
+respectively. For example:
+
+ /caseless/i
+
+These modifier letters have the same effect as they do in Perl. There are
+others which set PCRE options that do not correspond to anything in Perl:
+\fB/A\fR, \fB/E\fR, and \fB/X\fR set PCRE_ANCHORED, PCRE_DOLLAR_ENDONLY, and
+PCRE_EXTRA respectively.
+
+Searching for all possible matches within each subject string can be requested
+by the \fB/g\fR or \fB/G\fR modifier. After finding a match, PCRE is called
+again to search the remainder of the subject string. The difference between
+\fB/g\fR and \fB/G\fR is that the former uses the \fIstartoffset\fR argument to
+\fBpcre_exec()\fR to start searching at a new point within the entire string
+(which is in effect what Perl does), whereas the latter passes over a shortened
+substring. This makes a difference to the matching process if the pattern
+begins with a lookbehind assertion (including \\b or \\B).
+
+If any call to \fBpcre_exec()\fR in a \fB/g\fR or \fB/G\fR sequence matches an
+empty string, the next call is done with the PCRE_NOTEMPTY and PCRE_ANCHORED
+flags set in order to search for another, non-empty, match at the same point.
+If this second match fails, the start offset is advanced by one, and the normal
+match is retried. This imitates the way Perl handles such cases when using the
+\fB/g\fR modifier or the \fBsplit()\fR function.
+
+There are a number of other modifiers for controlling the way \fBpcretest\fR
+operates.
+
+The \fB/+\fR modifier requests that as well as outputting the substring that
+matched the entire pattern, pcretest should in addition output the remainder of
+the subject string. This is useful for tests where the subject contains
+multiple copies of the same substring.
+
+The \fB/L\fR modifier must be followed directly by the name of a locale, for
+example,
+
+ /pattern/Lfr
+
+For this reason, it must be the last modifier letter. The given locale is set,
+\fBpcre_maketables()\fR is called to build a set of character tables for the
+locale, and this is then passed to \fBpcre_compile()\fR when compiling the
+regular expression. Without an \fB/L\fR modifier, NULL is passed as the tables
+pointer; that is, \fB/L\fR applies only to the expression on which it appears.
+
+The \fB/I\fR modifier requests that \fBpcretest\fR output information about the
+compiled expression (whether it is anchored, has a fixed first character, and
+so on). It does this by calling \fBpcre_fullinfo()\fR after compiling an
+expression, and outputting the information it gets back. If the pattern is
+studied, the results of that are also output.
+
+The \fB/D\fR modifier is a PCRE debugging feature, which also assumes \fB/I\fR.
+It causes the internal form of compiled regular expressions to be output after
+compilation.
+
+The \fB/S\fR modifier causes \fBpcre_study()\fR to be called after the
+expression has been compiled, and the results used when the expression is
+matched.
+
+The \fB/M\fR modifier causes the size of memory block used to hold the compiled
+pattern to be output.
+
+The \fB/P\fR modifier causes \fBpcretest\fR to call PCRE via the POSIX wrapper
+API rather than its native API. When this is done, all other modifiers except
+\fB/i\fR, \fB/m\fR, and \fB/+\fR are ignored. REG_ICASE is set if \fB/i\fR is
+present, and REG_NEWLINE is set if \fB/m\fR is present. The wrapper functions
+force PCRE_DOLLAR_ENDONLY always, and PCRE_DOTALL unless REG_NEWLINE is set.
+
+The \fB/8\fR modifier causes \fBpcretest\fR to call PCRE with the PCRE_UTF8
+option set. This turns on the (currently incomplete) support for UTF-8
+character handling in PCRE, provided that it was compiled with this support
+enabled. This modifier also causes any non-printing characters in output
+strings to be printed using the \\x{hh...} notation if they are valid UTF-8
+sequences.
+
+
+.SH DATA LINES
+
+Before each data line is passed to \fBpcre_exec()\fR, leading and trailing
+whitespace is removed, and it is then scanned for \\ escapes. The following are
+recognized:
+
+ \\a alarm (= BEL)
+ \\b backspace
+ \\e escape
+ \\f formfeed
+ \\n newline
+ \\r carriage return
+ \\t tab
+ \\v vertical tab
+ \\nnn octal character (up to 3 octal digits)
+ \\xhh hexadecimal character (up to 2 hex digits)
+ \\x{hh...} hexadecimal UTF-8 character
+
+ \\A pass the PCRE_ANCHORED option to \fBpcre_exec()\fR
+ \\B pass the PCRE_NOTBOL option to \fBpcre_exec()\fR
+ \\Cdd call pcre_copy_substring() for substring dd
+ after a successful match (any decimal number
+ less than 32)
+ \\Gdd call pcre_get_substring() for substring dd
+ after a successful match (any decimal number
+ less than 32)
+ \\L call pcre_get_substringlist() after a
+ successful match
+ \\N pass the PCRE_NOTEMPTY option to \fBpcre_exec()\fR
+ \\Odd set the size of the output vector passed to
+ \fBpcre_exec()\fR to dd (any number of decimal
+ digits)
+ \\Z pass the PCRE_NOTEOL option to \fBpcre_exec()\fR
+
+When \\O is used, it may be higher or lower than the size set by the \fB-O\fR
+option (or defaulted to 45); \\O applies only to the call of \fBpcre_exec()\fR
+for the line in which it appears.
+
+A backslash followed by anything else just escapes the anything else. If the
+very last character is a backslash, it is ignored. This gives a way of passing
+an empty line as data, since a real empty line terminates the data input.
+
+If \fB/P\fR was present on the regex, causing the POSIX wrapper API to be used,
+only \fB\B\fR, and \fB\Z\fR have any effect, causing REG_NOTBOL and REG_NOTEOL
+to be passed to \fBregexec()\fR respectively.
+
+The use of \\x{hh...} to represent UTF-8 characters is not dependent on the use
+of the \fB/8\fR modifier on the pattern. It is recognized always. There may be
+any number of hexadecimal digits inside the braces. The result is from one to
+six bytes, encoded according to the UTF-8 rules.
+
+
+.SH OUTPUT FROM PCRETEST
+
+When a match succeeds, pcretest outputs the list of captured substrings that
+\fBpcre_exec()\fR returns, starting with number 0 for the string that matched
+the whole pattern. Here is an example of an interactive pcretest run.
+
+ $ pcretest
+ PCRE version 2.06 08-Jun-1999
+
+ re> /^abc(\\d+)/
+ data> abc123
+ 0: abc123
+ 1: 123
+ data> xyz
+ No match
+
+If the strings contain any non-printing characters, they are output as \\0x
+escapes, or as \\x{...} escapes if the \fB/8\fR modifier was present on the
+pattern. If the pattern has the \fB/+\fR modifier, then the output for
+substring 0 is followed by the the rest of the subject string, identified by
+"0+" like this:
+
+ re> /cat/+
+ data> cataract
+ 0: cat
+ 0+ aract
+
+If the pattern has the \fB/g\fR or \fB/G\fR modifier, the results of successive
+matching attempts are output in sequence, like this:
+
+ re> /\\Bi(\\w\\w)/g
+ data> Mississippi
+ 0: iss
+ 1: ss
+ 0: iss
+ 1: ss
+ 0: ipp
+ 1: pp
+
+"No match" is output only if the first match attempt fails.
+
+If any of the sequences \fB\\C\fR, \fB\\G\fR, or \fB\\L\fR are present in a
+data line that is successfully matched, the substrings extracted by the
+convenience functions are output with C, G, or L after the string number
+instead of a colon. This is in addition to the normal full list. The string
+length (that is, the return from the extraction function) is given in
+parentheses after each string for \fB\\C\fR and \fB\\G\fR.
+
+Note that while patterns can be continued over several lines (a plain ">"
+prompt is used for continuations), data lines may not. However newlines can be
+included in data by means of the \\n escape.

+pcretest - a program for testing Perl-compatible regular expressions.
+</P>
+<LI><A NAME="SEC2" HREF="#TOC1">SYNOPSIS</A>
+<P>
+<B>pcretest [-d] [-i] [-m] [-o osize] [-p] [-t] [source] [destination]</B>
+</P>
+<P>
+<B>pcretest</B> was written as a test program for the PCRE regular expression
+library itself, but it can also be used for experimenting with regular
+expressions. This man page describes the features of the test program; for
+details of the regular expressions themselves, see the <B>pcre</B> man page.
+</P>
+<LI><A NAME="SEC3" HREF="#TOC1">OPTIONS</A>
+<P>
+<B>-d</B>
+Behave as if each regex had the <B>/D</B> modifier (see below); the internal
+form is output after compilation.
+</P>
+<P>
+<B>-i</B>
+Behave as if each regex had the <B>/I</B> modifier; information about the
+compiled pattern is given after compilation.
+</P>
+<P>
+<B>-m</B>
+Output the size of each compiled pattern after it has been compiled. This is
+equivalent to adding /M to each regular expression. For compatibility with
+earlier versions of pcretest, <B>-s</B> is a synonym for <B>-m</B>.
+</P>
+<P>
+<B>-o</B> <I>osize</I>
+Set the number of elements in the output vector that is used when calling PCRE
+to be <I>osize</I>. The default value is 45, which is enough for 14 capturing
+subexpressions. The vector size can be changed for individual matching calls by
+including \O in the data line (see below).
+</P>
+<P>
+<B>-p</B>
+Behave as if each regex has <B>/P</B> modifier; the POSIX wrapper API is used
+to call PCRE. None of the other options has any effect when <B>-p</B> is set.
+</P>
+<P>
+<B>-t</B>
+Run each compile, study, and match 20000 times with a timer, and output
+resulting time per compile or match (in milliseconds). Do not set <B>-t</B> with
+<B>-m</B>, because you will then get the size output 20000 times and the timing
+will be distorted.
+</P>
+<LI><A NAME="SEC4" HREF="#TOC1">DESCRIPTION</A>
+<P>
+If <B>pcretest</B> is given two filename arguments, it reads from the first and
+writes to the second. If it is given only one filename argument, it reads from
+that file and writes to stdout. Otherwise, it reads from stdin and writes to
+stdout, and prompts for each line of input, using "re&#62;" to prompt for regular
+expressions, and "data&#62;" to prompt for data lines.
+</P>
+<P>
+The program handles any number of sets of input on a single input file. Each
+set starts with a regular expression, and continues with any number of data
+lines to be matched against the pattern. An empty line signals the end of the
+data lines, at which point a new regular expression is read. The regular
+expressions are given enclosed in any non-alphameric delimiters other than
+backslash, for example
+</P>
+<P>
+<PRE>
+ /(a|bc)x+yz/
+</PRE>
+</P>
+<P>
+White space before the initial delimiter is ignored. A regular expression may
+be continued over several input lines, in which case the newline characters are
+included within it. It is possible to include the delimiter within the pattern
+by escaping it, for example
+</P>
+<P>
+<PRE>
+ /abc\/def/
+</PRE>
+</P>
+<P>
+If you do so, the escape and the delimiter form part of the pattern, but since
+delimiters are always non-alphameric, this does not affect its interpretation.
+If the terminating delimiter is immediately followed by a backslash, for
+example,
+</P>
+<P>
+<PRE>
+ /abc/\
+</PRE>
+</P>
+<P>
+then a backslash is added to the end of the pattern. This is done to provide a
+way of testing the error condition that arises if a pattern finishes with a
+backslash, because
+</P>
+<P>
+<PRE>
+ /abc\/
+</PRE>
+</P>
+<P>
+is interpreted as the first line of a pattern that starts with "abc/", causing
+pcretest to read the next line as a continuation of the regular expression.
+</P>
+<LI><A NAME="SEC5" HREF="#TOC1">PATTERN MODIFIERS</A>
+<P>
+The pattern may be followed by <B>i</B>, <B>m</B>, <B>s</B>, or <B>x</B> to set the
+PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, or PCRE_EXTENDED options,
+respectively. For example:
+</P>
+<P>
+<PRE>
+ /caseless/i
+</PRE>
+</P>
+<P>
+These modifier letters have the same effect as they do in Perl. There are
+others which set PCRE options that do not correspond to anything in Perl:
+<B>/A</B>, <B>/E</B>, and <B>/X</B> set PCRE_ANCHORED, PCRE_DOLLAR_ENDONLY, and
+PCRE_EXTRA respectively.
+</P>
+<P>
+Searching for all possible matches within each subject string can be requested
+by the <B>/g</B> or <B>/G</B> modifier. After finding a match, PCRE is called
+again to search the remainder of the subject string. The difference between
+<B>/g</B> and <B>/G</B> is that the former uses the <I>startoffset</I> argument to
+<B>pcre_exec()</B> to start searching at a new point within the entire string
+(which is in effect what Perl does), whereas the latter passes over a shortened
+substring. This makes a difference to the matching process if the pattern
+begins with a lookbehind assertion (including \b or \B).
+</P>
+<P>
+If any call to <B>pcre_exec()</B> in a <B>/g</B> or <B>/G</B> sequence matches an
+empty string, the next call is done with the PCRE_NOTEMPTY and PCRE_ANCHORED
+flags set in order to search for another, non-empty, match at the same point.
+If this second match fails, the start offset is advanced by one, and the normal
+match is retried. This imitates the way Perl handles such cases when using the
+<B>/g</B> modifier or the <B>split()</B> function.
+</P>
+<P>
+There are a number of other modifiers for controlling the way <B>pcretest</B>
+operates.
+</P>
+<P>
+The <B>/+</B> modifier requests that as well as outputting the substring that
+matched the entire pattern, pcretest should in addition output the remainder of
+the subject string. This is useful for tests where the subject contains
+multiple copies of the same substring.
+</P>
+<P>
+The <B>/L</B> modifier must be followed directly by the name of a locale, for
+example,
+</P>
+<P>
+<PRE>
+ /pattern/Lfr
+</PRE>
+</P>
+<P>
+For this reason, it must be the last modifier letter. The given locale is set,
+<B>pcre_maketables()</B> is called to build a set of character tables for the
+locale, and this is then passed to <B>pcre_compile()</B> when compiling the
+regular expression. Without an <B>/L</B> modifier, NULL is passed as the tables
+pointer; that is, <B>/L</B> applies only to the expression on which it appears.
+</P>
+<P>
+The <B>/I</B> modifier requests that <B>pcretest</B> output information about the
+compiled expression (whether it is anchored, has a fixed first character, and
+so on). It does this by calling <B>pcre_fullinfo()</B> after compiling an
+expression, and outputting the information it gets back. If the pattern is
+studied, the results of that are also output.
+</P>
+<P>
+The <B>/D</B> modifier is a PCRE debugging feature, which also assumes <B>/I</B>.
+It causes the internal form of compiled regular expressions to be output after
+compilation.
+</P>
+<P>
+The <B>/S</B> modifier causes <B>pcre_study()</B> to be called after the
+expression has been compiled, and the results used when the expression is
+matched.
+</P>
+<P>
+The <B>/M</B> modifier causes the size of memory block used to hold the compiled
+pattern to be output.
+</P>
+<P>
+The <B>/P</B> modifier causes <B>pcretest</B> to call PCRE via the POSIX wrapper
+API rather than its native API. When this is done, all other modifiers except
+<B>/i</B>, <B>/m</B>, and <B>/+</B> are ignored. REG_ICASE is set if <B>/i</B> is
+present, and REG_NEWLINE is set if <B>/m</B> is present. The wrapper functions
+force PCRE_DOLLAR_ENDONLY always, and PCRE_DOTALL unless REG_NEWLINE is set.
+</P>
+<P>
+The <B>/8</B> modifier causes <B>pcretest</B> to call PCRE with the PCRE_UTF8
+option set. This turns on the (currently incomplete) support for UTF-8
+character handling in PCRE, provided that it was compiled with this support
+enabled. This modifier also causes any non-printing characters in output
+strings to be printed using the \x{hh...} notation if they are valid UTF-8
+sequences.
+</P>
+<LI><A NAME="SEC6" HREF="#TOC1">DATA LINES</A>
+<P>
+Before each data line is passed to <B>pcre_exec()</B>, leading and trailing
+whitespace is removed, and it is then scanned for \ escapes. The following are
+recognized:
+</P>
+<P>
+<PRE>
+ \a alarm (= BEL)
+ \b backspace
+ \e escape
+ \f formfeed
+ \n newline
+ \r carriage return
+ \t tab
+ \v vertical tab
+ \nnn octal character (up to 3 octal digits)
+ \xhh hexadecimal character (up to 2 hex digits)
+ \x{hh...} hexadecimal UTF-8 character
+</PRE>
+</P>
+<P>
+<PRE>
+ \A pass the PCRE_ANCHORED option to <B>pcre_exec()</B>
+ \B pass the PCRE_NOTBOL option to <B>pcre_exec()</B>
+ \Cdd call pcre_copy_substring() for substring dd
+ after a successful match (any decimal number
+ less than 32)
+ \Gdd call pcre_get_substring() for substring dd
+ after a successful match (any decimal number
+ less than 32)
+ \L call pcre_get_substringlist() after a
+ successful match
+ \N pass the PCRE_NOTEMPTY option to <B>pcre_exec()</B>
+ \Odd set the size of the output vector passed to
+ <B>pcre_exec()</B> to dd (any number of decimal
+ digits)
+ \Z pass the PCRE_NOTEOL option to <B>pcre_exec()</B>
+</PRE>
+</P>
+<P>
+When \O is used, it may be higher or lower than the size set by the <B>-O</B>
+option (or defaulted to 45); \O applies only to the call of <B>pcre_exec()</B>
+for the line in which it appears.
+</P>
+<P>
+A backslash followed by anything else just escapes the anything else. If the
+very last character is a backslash, it is ignored. This gives a way of passing
+an empty line as data, since a real empty line terminates the data input.
+</P>
+<P>
+If <B>/P</B> was present on the regex, causing the POSIX wrapper API to be used,
+only <B>\B</B>, and <B>\Z</B> have any effect, causing REG_NOTBOL and REG_NOTEOL
+to be passed to <B>regexec()</B> respectively.
+</P>
+<P>
+The use of \x{hh...} to represent UTF-8 characters is not dependent on the use
+of the <B>/8</B> modifier on the pattern. It is recognized always. There may be

+NAME
+ pcretest - a program for testing Perl-compatible regular
+ expressions.
+
+
+
+SYNOPSIS
+ pcretest [-d] [-i] [-m] [-o osize] [-p] [-t] [source] [des-
+ tination]
+
+ pcretest was written as a test program for the PCRE regular
+ expression library itself, but it can also be used for
+ experimenting with regular expressions. This man page
+ describes the features of the test program; for details of
+ the regular expressions themselves, see the pcre man page.
+
+
+
+OPTIONS
+ -d Behave as if each regex had the /D modifier (see
+ below); the internal form is output after compila-
+ tion.
+
+ -i Behave as if each regex had the /I modifier;
+ information about the compiled pattern is given
+ after compilation.
+
+ -m Output the size of each compiled pattern after it
+ has been compiled. This is equivalent to adding /M
+ to each regular expression. For compatibility with
+ earlier versions of pcretest, -s is a synonym for
+ -m.
+
+ -o osize Set the number of elements in the output vector
+ that is used when calling PCRE to be osize. The
+ default value is 45, which is enough for 14 cap-
+ turing subexpressions. The vector size can be
+ changed for individual matching calls by including
+ \O in the data line (see below).
+
+ -p Behave as if each regex has /P modifier; the POSIX
+ wrapper API is used to call PCRE. None of the
+ other options has any effect when -p is set.
+
+ -t Run each compile, study, and match 20000 times
+ with a timer, and output resulting time per com-
+ pile or match (in milliseconds). Do not set -t
+ with -m, because you will then get the size output
+ 20000 times and the timing will be distorted.
+
+
+
+DESCRIPTION
+ If pcretest is given two filename arguments, it reads from
+ the first and writes to the second. If it is given only one
+
+
+
+
+SunOS 5.8 Last change: 1
+
+
+
+ filename argument, it reads from that file and writes to
+ stdout. Otherwise, it reads from stdin and writes to stdout,
+ and prompts for each line of input, using "re>" to prompt
+ for regular expressions, and "data>" to prompt for data
+ lines.
+
+ The program handles any number of sets of input on a single
+ input file. Each set starts with a regular expression, and
+ continues with any number of data lines to be matched
+ against the pattern. An empty line signals the end of the
+ data lines, at which point a new regular expression is read.
+ The regular expressions are given enclosed in any non-
+ alphameric delimiters other than backslash, for example
+
+ /(a|bc)x+yz/
+
+ White space before the initial delimiter is ignored. A regu-
+ lar expression may be continued over several input lines, in
+ which case the newline characters are included within it. It
+ is possible to include the delimiter within the pattern by
+ escaping it, for example
+
+ /abc\/def/
+
+ If you do so, the escape and the delimiter form part of the
+ pattern, but since delimiters are always non-alphameric,
+ this does not affect its interpretation. If the terminating
+ delimiter is immediately followed by a backslash, for exam-
+ ple,
+
+ /abc/\
+
+ then a backslash is added to the end of the pattern. This is
+ done to provide a way of testing the error condition that
+ arises if a pattern finishes with a backslash, because
+
+ /abc\/
+
+ is interpreted as the first line of a pattern that starts
+ with "abc/", causing pcretest to read the next line as a
+ continuation of the regular expression.
+
+
+
+PATTERN MODIFIERS
+ The pattern may be followed by i, m, s, or x to set the
+ PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, or PCRE_EXTENDED
+ options, respectively. For example:
+
+ /caseless/i
+
+ These modifier letters have the same effect as they do in
+ Perl. There are others which set PCRE options that do not
+ correspond to anything in Perl: /A, /E, and /X set
+ PCRE_ANCHORED, PCRE_DOLLAR_ENDONLY, and PCRE_EXTRA respec-
+ tively.
+
+ Searching for all possible matches within each subject
+ string can be requested by the /g or /G modifier. After
+ finding a match, PCRE is called again to search the
+ remainder of the subject string. The difference between /g
+ and /G is that the former uses the startoffset argument to
+ pcre_exec() to start searching at a new point within the
+ entire string (which is in effect what Perl does), whereas
+ the latter passes over a shortened substring. This makes a
+ difference to the matching process if the pattern begins
+ with a lookbehind assertion (including \b or \B).
+
+ If any call to pcre_exec() in a /g or /G sequence matches an
+ empty string, the next call is done with the PCRE_NOTEMPTY
+ and PCRE_ANCHORED flags set in order to search for another,
+ non-empty, match at the same point. If this second match
+ fails, the start offset is advanced by one, and the normal
+ match is retried. This imitates the way Perl handles such
+ cases when using the /g modifier or the split() function.
+
+ There are a number of other modifiers for controlling the
+ way pcretest operates.
+
+ The /+ modifier requests that as well as outputting the sub-
+ string that matched the entire pattern, pcretest should in
+ addition output the remainder of the subject string. This is
+ useful for tests where the subject contains multiple copies
+ of the same substring.
+
+ The /L modifier must be followed directly by the name of a
+ locale, for example,
+
+ /pattern/Lfr
+
+ For this reason, it must be the last modifier letter. The
+ given locale is set, pcre_maketables() is called to build a
+ set of character tables for the locale, and this is then
+ passed to pcre_compile() when compiling the regular expres-
+ sion. Without an /L modifier, NULL is passed as the tables
+ pointer; that is, /L applies only to the expression on which
+ it appears.
+
+ The /I modifier requests that pcretest output information
+ about the compiled expression (whether it is anchored, has a
+ fixed first character, and so on). It does this by calling
+ pcre_fullinfo() after compiling an expression, and output-
+ ting the information it gets back. If the pattern is stu-
+ died, the results of that are also output.
+ The /D modifier is a PCRE debugging feature, which also
+ assumes /I. It causes the internal form of compiled regular
+ expressions to be output after compilation.
+
+ The /S modifier causes pcre_study() to be called after the
+ expression has been compiled, and the results used when the
+ expression is matched.
+
+ The /M modifier causes the size of memory block used to hold
+ the compiled pattern to be output.
+
+ The /P modifier causes pcretest to call PCRE via the POSIX
+ wrapper API rather than its native API. When this is done,
+ all other modifiers except /i, /m, and /+ are ignored.
+ REG_ICASE is set if /i is present, and REG_NEWLINE is set if
+ /m is present. The wrapper functions force
+ PCRE_DOLLAR_ENDONLY always, and PCRE_DOTALL unless
+ REG_NEWLINE is set.
+
+ The /8 modifier causes pcretest to call PCRE with the
+ PCRE_UTF8 option set. This turns on the (currently incom-
+ plete) support for UTF-8 character handling in PCRE, pro-
+ vided that it was compiled with this support enabled. This
+ modifier also causes any non-printing characters in output
+ strings to be printed using the \x{hh...} notation if they
+ are valid UTF-8 sequences.
+
+
+
+DATA LINES
+ Before each data line is passed to pcre_exec(), leading and
+ trailing whitespace is removed, and it is then scanned for \
+ escapes. The following are recognized:
+
+ \a alarm (= BEL)
+ \b backspace
+ \e escape
+ \f formfeed
+ \n newline
+ \r carriage return
+ \t tab
+ \v vertical tab
+ \nnn octal character (up to 3 octal digits)
+ \xhh hexadecimal character (up to 2 hex digits)
+ \x{hh...} hexadecimal UTF-8 character
+
+ \A pass the PCRE_ANCHORED option to pcre_exec()
+ \B pass the PCRE_NOTBOL option to pcre_exec()
+ \Cdd call pcre_copy_substring() for substring dd
+ after a successful match (any decimal number
+ less than 32)
+ \Gdd call pcre_get_substring() for substring dd
+
+ after a successful match (any decimal number
+ less than 32)
+ \L call pcre_get_substringlist() after a
+ successful match
+ \N pass the PCRE_NOTEMPTY option to pcre_exec()
+ \Odd set the size of the output vector passed to
+ pcre_exec() to dd (any number of decimal
+ digits)
+ \Z pass the PCRE_NOTEOL option to pcre_exec()
+
+ When \O is used, it may be higher or lower than the size set
+ by the -O option (or defaulted to 45); \O applies only to
+ the call of pcre_exec() for the line in which it appears.
+
+ A backslash followed by anything else just escapes the any-
+ thing else. If the very last character is a backslash, it is
+ ignored. This gives a way of passing an empty line as data,
+ since a real empty line terminates the data input.
+
+ If /P was present on the regex, causing the POSIX wrapper
+ API to be used, only B, and Z have any effect, causing
+ REG_NOTBOL and REG_NOTEOL to be passed to regexec() respec-
+ tively.
+
+ The use of \x{hh...} to represent UTF-8 characters is not
+ dependent on the use of the /8 modifier on the pattern. It
+ is recognized always. There may be any number of hexadecimal
+ digits inside the braces. The result is from one to six
+ bytes, encoded according to the UTF-8 rules.
+
+
+
+OUTPUT FROM PCRETEST
+ When a match succeeds, pcretest outputs the list of captured
+ substrings that pcre_exec() returns, starting with number 0
+ for the string that matched the whole pattern. Here is an
+ example of an interactive pcretest run.
+
+ $ pcretest
+ PCRE version 2.06 08-Jun-1999
+
+ re> /^abc(\d+)/
+ data> abc123
+ 0: abc123
+ 1: 123
+ data> xyz
+ No match
+
+ If the strings contain any non-printing characters, they are
+ output as \0x escapes, or as \x{...} escapes if the /8
+ modifier was present on the pattern. If the pattern has the
+ /+ modifier, then the output for substring 0 is followed by
+ the the rest of the subject string, identified by "0+" like
+ this:
+
+ re> /cat/+
+ data> cataract
+ 0: cat
+ 0+ aract
+
+ If the pattern has the /g or /G modifier, the results of
+ successive matching attempts are output in sequence, like
+ this:
+
+ re> /\Bi(\w\w)/g
+ data> Mississippi
+ 0: iss
+ 1: ss
+ 0: iss
+ 1: ss
+ 0: ipp
+ 1: pp
+
+ "No match" is output only if the first match attempt fails.
+
+ If any of the sequences \C, \G, or \L are present in a data
+ line that is successfully matched, the substrings extracted
+ by the convenience functions are output with C, G, or L
+ after the string number instead of a colon. This is in addi-
+ tion to the normal full list. The string length (that is,
+ the return from the extraction function) is given in
+ parentheses after each string for \C and \G.
+
+ Note that while patterns can be continued over several lines
+ (a plain ">" prompt is used for continuations), data lines
+ may not. However newlines can be included in data by means
+ of the \n escape.

+The perltest program
+--------------------
+
+The perltest program tests Perl's regular expressions; it has the same
+specification as pcretest, and so can be given identical input, except that
+input patterns can be followed only by Perl's lower case modifiers and /+ (as
+used by pcretest), which is recognized and handled by the program.
+
+The data lines are processed as Perl double-quoted strings, so if they contain
+" \ $ or @ characters, these have to be escaped. For this reason, all such
+characters in testinput1 and testinput3 are escaped so that they can be used
+for perltest as well as for pcretest, and the special upper case modifiers such
+as /A that pcretest recognizes are not used in these files. The output should
+be identical, apart from the initial identifying banner.
+
+For testing UTF-8 features, an alternative form of perltest, called perltest8,
+is supplied. This requires Perl 5.6 or higher. It recognizes the special
+modifier /8 that pcretest uses to invoke UTF-8 functionality. The testinput5
+file can be fed to perltest8.
+
+The testinput2 and testinput4 files are not suitable for feeding to perltest,
+since they do make use of the special upper case modifiers and escapes that
+pcretest uses to test some features of PCRE. The first of these files also
+contains malformed regular expressions, in order to check that PCRE diagnoses
+them correctly. Similarly, testinput6 tests UTF-8 features that do not relate
+to Perl.

+.TH PGREP 1
+.SH NAME
+pgrep - a grep with Perl-compatible regular expressions.
+.SH SYNOPSIS
+.B pgrep [-Vchilnsvx] pattern [file] ...
+
+
+.SH DESCRIPTION
+\fBpgrep\fR searches files for character patterns, in the same way as other
+grep commands do, but it uses the PCRE regular expression library to support
+patterns that are compatible with the regular expressions of Perl 5. See
+\fBpcre(3)\fR for a full description of syntax and semantics.
+
+If no files are specified, \fBpgrep\fR reads the standard input. By default,
+each line that matches the pattern is copied to the standard output, and if
+there is more than one file, the file name is printed before each line of
+output. However, there are options that can change how \fBpgrep\fR behaves.
+
+Lines are limited to BUFSIZ characters. BUFSIZ is defined in \fB<stdio.h>\fR.
+The newline character is removed from the end of each line before it is matched
+against the pattern.
+
+
+.SH OPTIONS
+.TP 10
+\fB-V\fR
+Write the version number of the PCRE library being used to the standard error
+stream.
+.TP
+\fB-c\fR
+Do not print individual lines; instead just print a count of the number of
+lines that would otherwise have been printed. If several files are given, a
+count is printed for each of them.
+.TP
+\fB-h\fR
+Suppress printing of filenames when searching multiple files.
+.TP
+\fB-i\fR
+Ignore upper/lower case distinctions during comparisons.
+.TP
+\fB-l\fR
+Instead of printing lines from the files, just print the names of the files
+containing lines that would have been printed. Each file name is printed
+once, on a separate line.
+.TP
+\fB-n\fR
+Precede each line by its line number in the file.
+.TP
+\fB-s\fR
+Work silently, that is, display nothing except error messages.
+The exit status indicates whether any matches were found.
+.TP
+\fB-v\fR
+Invert the sense of the match, so that lines which do \fInot\fR match the
+pattern are now the ones that are found.
+.TP
+\fB-x\fR
+Force the pattern to be anchored (it must start matching at the beginning of
+the line) and in addition, require it to match the entire line. This is
+equivalent to having ^ and $ characters at the start and end of each
+alternative branch in the regular expression.
+
+
+.SH SEE ALSO
+\fBpcre(3)\fR, Perl 5 documentation
+
+
+.SH DIAGNOSTICS
+Exit status is 0 if any matches were found, 1 if no matches were found, and 2
+for syntax errors or inacessible files (even if matches were found).
