# TODO(devvesa): Remove the validation function once puppetlabs-stdlib maintainers
# accept the pull request: https://github.com/puppetlabs/puppetlabs-stdlib/pull/546
# This project should not maintain it.
module Puppet::Parser::Functions
newfunction(:validate_ip_address, :doc => <<-ENDHEREDOC
Validate that all values passed are valid IP addresses,
regardless they are IPv4 or IPv6
Fail compilation if any value fails this check.
The following values will pass:
$my_ip = "1.2.3.4"
validate_ip_address($my_ip)
validate_bool("8.8.8.8", "172.16.0.1", $my_ip)
$my_ip = "3ffe:505:2"
validate_ip_address(1)
validate_ip_address($my_ip)
validate_bool("fe80::baf6:b1ff:fe19:7507", $my_ip)
The following values will fail, causing compilation to abort:
$some_array = [ 1, true, false, "garbage string", "3ffe:505:2" ]
validate_ip_address($some_array)
