|
|
||
|
|
Git::I18N - Perl interface to Git's Gettext localizations
|
||
|
|
|
||
|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
use Git::I18N;
|
||
|
|
|
||
|
|
print __("Welcome to Git!\n");
|
||
|
|
|
||
|
|
printf __("The following error occured: %s\n"), $error;
|
||
|
|
|
||
|
|
=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.
