Name

Dist::Zilla::Plugin::LocaleTextDomain - Compile Local::TextDomain language files

Synopsis

In dist.ini:

  [ShareDir]
  [LocaleTextDomain]
  textdomain = My-App
  lang_dir = po
  share_dir = share

Description

This plugin compiles GNU gettext language files and adds them into the distribution for use by Locale::TextDomain. This is useful if your distribution maintains gettext language files in a directory, with each file named for a language. The plugin uses msgfmt to compile each file and then adds it to the distribution's share directory. You can then use the ShareDir plugin to make sure it gets installed in the right place.

Installation

Ideally, Locale::TextDomain would search for language files in the shared directory for your distribution, as defined by File::ShareDir. A patch has been submitted to add this support, after which the example code from the "Synopsis" should just work.

Until that time, however, Locale::TextDomain searches for files in Perl's @INC directories, in which case the use of the ShareDir plugin will not work. You will have to install the compiled language files into the lib directory in your distribution. To do so, simply set the share_dir attribute to "lib":

  [LocaleTextDomain]
  textdomain = My-App
  lang_dir = po
  share_dir = lib

If your distribution uses ExtUtils::MakeMaker to do the installation, the files will now be installed in the proper location. If it relies on Module::Build, you will have to do a bit of additional work. First, subclass Module::Build by creating inc/Module/Build/MyApp.pm with this code:

  package Module::Build::MyApp;
  use parent 'Module::Build';

  sub new {
      my ( $class, %p ) = @_;
      my $self = $class->SUPER::new(%p);
      $self->add_build_element('mo');
      return $self;
  }

Then tell Dist::Zilla to use the subclass via the mb_class attribute in dist.ini:

  [ModuleBuild]
  mb_class = Module::Build::MyApp

Now the .mo files will be installed where Locale::TextDomain can find them.

Configuration

Configuration attributes settable in dist.ini to change the plugin behavior.

textdomain

The textdomain to use for your language files, as defined by the Locale::TextDomain documentation. This should be the same value declared in each use of Locale::TextDomain in your module. For example, if such lines look like this:

  use LocaleText::Domain qw(com.example.myApp);

Then set it to such in your dist.ini

  [LocaleTextDomain]
  textdomain = com.example.myApp

Defaults to the name of your distribution, which is the value that Locale::TextDomain recommends you use.

lang_dir

The directory containing your language files. Defaults to po.

share_dir

The name of the distribution directory into which compiled language files should be added. Defaults to share.

msgfmt

The location of the msgfmt program, which is distributed with GNU gettext. Defaults to just msgfmt, which should work if it's in your path.

language

A language to be compiled. May be specified more than once. If not specified, the default will be the list of files in lang_dir ending in lange_file_suffix.

lang_file_suffix

Suffix used in the language file names. These are the files your translators maintain in your repository. Defaults to po.

bin_file_suffix

Suffix to use for the compiled language file. Defaults to mo.
