<title>FixCRLF Task</title>
</head>
<body>
<h2><a name="fixcrlf">FixCRLF</a></h2>
<h3>Description</h3>
<p>
Adjusts a text file to local conventions.
</p>
<p>
The set of files to be adjusted can be refined with the
<i>includes</i>, <i>includesfile</i>, <i>excludes</i>,
<i>excludesfile</i> and <i>defaultexcludes</i>
attributes. Patterns provided through the <i>includes</i> or
<i>includesfile</i> attributes specify files to be
included. Patterns provided through the <i>exclude</i> or
<i>excludesfile</i> attribute specify files to be
excluded. Additionally, default exclusions can be specified with
the <i>defaultexcludes</i> attribute. See the section on <a
href="../dirtasks.html#directorybasedtasks">directory-based
tasks</a>, for details of file inclusion/exclusion patterns
and their usage.
</p>
<p>
This task forms an implicit
<a href="../Types/fileset.html">FileSet</a> and
supports most attributes of <code><fileset></code>
(<code>dir</code> becomes <code>srcdir</code>) as well as the nested
<code><include></code>, <code><exclude></code> and
<code><patternset></code> elements.
</p>
<p>
The output file is only written if it is a new file, or if it
differs from the existing file. This prevents spurious
rebuilds based on unchanged files which have been regenerated
by this task.
</p>
<p>
Since <b>Apache Ant 1.7</b>, this task can be used in a
<a href="../Types/filterchain.html">filterchain</a>.
</p>

<tr>
<td valign="top">eol</td>
<td valign="top">
Specifies how end-of-line (EOL) characters are to be
handled. The EOL characters are CR, LF and the pair CRLF.
Valid values for this property are:
<ul>
<li>asis: leave EOL characters alone</li>
<li>cr: convert all EOLs to a single CR</li>
<li>lf: convert all EOLs to a single LF</li>
<li>crlf: convert all EOLs to the pair CRLF</li>
<li>mac: convert all EOLs to a single CR</li>
<li>unix: convert all EOLs to a single LF</li>
<li>dos: convert all EOLs to the pair CRLF</li>
</ul>
Default is based on the platform on which you are running this task.
For Unix platforms (including Mac OS X), the default is "lf".
For DOS-based systems (including Windows), the default is
"crlf".
For Mac environments other than OS X, the default is "cr".
<p>
This is the preferred method for specifying EOL. The
"<i><b>cr</b></i>" attribute (see below) is
now deprecated.
</p>
<p>
<i>N.B.</i>: One special case is recognized. The three
characters CR-CR-LF are regarded as a single EOL.
Unless this property is specified as "asis",
this sequence will be converted into the specified EOL
type.
</p>

<tr>
<td valign="top">cr</td>
<td valign="top">
<i><b>Deprecated.</b></i> Specifies how CR characters are
to be handled at end-of-line (EOL). Valid values for this
property are:
<ul>
<li>asis: leave EOL characters alone.</li>
<li>
add: add a CR before any single LF characters. The
intent is to convert all EOLs to the pair CRLF.
</li>
<li>
remove: remove all CRs from the file. The intent is
to convert all EOLs to a single LF.
</li>
</ul>
Default is based on the platform on which you are running
this task. For Unix platforms, the default is "remove".
For DOS based systems (including Windows), the default is
"add".

<i>N.B.</i>: One special case is recognized. The three

Used only in association with the

"no". See notes in section on "tab".

Default for this parameter is "asis".
<p>
<i>N.B.</i>: When the attribute
"<i><b>javafiles</b></i>" (see above) is
"true", literal TAB characters occurring
within Java string or character constants are never
modified. This functionality also requires the
recognition of Java-style comments.

<li>remove: remove any EOF character found at the end</li>

<h3>Examples</h3>
<pre><fixcrlf srcdir="${src}" includes="**/*.sh"
eol="lf" eof="remove" /></pre>
<p>Replaces EOLs with LF characters and removes eof characters from
the shell scripts. Tabs and spaces are left as is.</p>
<pre><fixcrlf srcdir="${src}"
includes="**/*.bat" eol="crlf" /></pre>
<p>Replaces all EOLs with cr-lf pairs in the batch files.
Tabs and spaces are left as is.
EOF characters are left alone if run on
DOS systems, and are removed if run on Unix systems.</p>
<pre><fixcrlf srcdir="${src}"
includes="**/Makefile" tab="add" /></pre>
<p>Sets EOLs according to local OS conventions, and
converts sequences of spaces and tabs to the minimal set of spaces and
tabs which will maintain spacing within the line. Tabs are
set at 8 character intervals. EOF characters are left alone if
run on DOS systems, and are removed if run on Unix systems.
Many versions of make require tabs prior to commands.</p>
<pre><fixcrlf srcdir="${src}" includes="**/*.java"
tab="remove" tablength="3"
eol="lf" javafiles="yes" /></pre>
<p>
Converts all EOLs in the included java source files to a
single LF. Replace all TAB characters except those in string
or character constants with spaces, assuming a tab width of 3.
If run on a unix system, any CTRL-Z EOF characters at the end
of the file are removed. On DOS/Windows, any such EOF
characters will be left untouched.
</p>
<pre><fixcrlf srcdir="${src}"
includes="**/README*" tab="remove" /></pre>
<p>Sets EOLs according to local OS conventions, and
converts all tabs to spaces, assuming a tab width of 8.
EOF characters are left alone if run on
DOS systems, and are removed if run on Unix systems.
You never know what editor a user will use to browse READMEs.</p>
