Test::Regexp::Pattern - Test Regexp::Pattern patterns


This document describes version 0.010 of Test::Regexp::Pattern (from Perl distribution Test-Regexp-Pattern), released on 2022-07-24.


To check all regexp patterns in a module:

 use Test::Regexp::Pattern;
 regexp_patterns_in_module_ok("Foo::Bar", {opt => ...}, $msg);

Alternatively, you can check all regexp patterns in all modules in a distro:

 # save in release-regexp-pattern.t, put in distro's t/ subdirectory
 use Test::More;
 plan skip_all => "Not release testing" unless $ENV{RELEASE_TESTING};
 eval "use Test::Regexp::Pattern";
 plan skip_all => "Test::Regexp::Pattern required for testing Regexp::Pattern patterns" if $@;
 regexp_patterns_in_all_modules_ok({opt => ...}, $msg);


This module performs various checks on a module's Regexp::Pattern patterns. It is recommended that you include something like the above release-regexp-pattern.t in your distribution if you add regexp patterns to your code. If you use Dist::Zilla to build your distribution, there is a [Regexp::Pattern] plugin which automatically adds this release test file during build.


Some code taken from Test::Pod::Coverage by Andy Lester.


All these functions are exported by default.

regexp_patterns_in_module_ok($module [, \%opts ] [, $msg])

Load $module and perform test for regexp patterns (%RE) in the module.

Available options:

  • test_examples => bool (default: 1)

regexp_patterns_in_all_modules_ok([ \%opts ] [, $msg])

Look for modules in directory lib (or blib instead, if it exists), and run regexp_patterns_in_module_ok() against each of them.

Options are the same as in regexp_patterns_in_module_ok().

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
