| =head1 NAME |
| |
| Git::I18N - Perl interface to Git's Gettext localizations |
| |
| =head1 SYNOPSIS |
| |
| use Git::I18N; |
| |
| print __("Welcome to Git!\n"); |
| |
| printf __("The following error occurred: %s\n"), $error; |
| |
| printf __n("committed %d file\n", "committed %d files\n", $files), $files; |
| |
| |
| =head1 DESCRIPTION |
| |
| Git's internal Perl interface to gettext via L<Locale::Messages>. If |
| L<Locale::Messages> can't be loaded (it's not a core module) we |
| provide stub passthrough fallbacks. |
| |
| This is a distilled interface to gettext, see C<info '(gettext)Perl'> |
| for the full interface. This module implements only a small part of |
| it. |
| |
| =head1 FUNCTIONS |
| |
| =head2 __($) |
| |
| L<Locale::Messages>'s gettext function if all goes well, otherwise our |
| passthrough fallback function. |
| |
| =head2 __n($$$) |
| |
| L<Locale::Messages>'s ngettext function or passthrough fallback function. |
| |
| =head2 N__($) |
| |
| No-operation that only returns its argument. Use this if you want xgettext to |
| extract the text to the pot template but do not want to trigger retrieval of the |
| translation at run time. |
