=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 retrival of the |
|
translation at run time. |
