All of the interface messages in Git core are currently hardcoded in
English. Change that by optionally enabling translation of the core C,
Shell and Perl programs via GNU gettext. If you set the appropriate
LC_* variables Git will speak your language, provided that someone has
submitted a translation.
If gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, then Git fall back on its previous behavior of
only speaking English.
With NO_GETTEXT=YesPlease gettext support will be #defined away for C
programs. For Shell and Perl programs we rely on the git message
catalog not being avalalable. That's a reasonable assumption since the
*.po files won't be installed on the system during make install.
The gettext wrappers that are provided in the patch are only the bare
minimum required to begin translation work. In particular I haven't
added wrappers for the gettext functions that enable plural support,
or those that provide message context (msgctxt). Those can be added
later. The intent is to start with a small subset and see what we need
later, not to start with something that's unnecessarily large right
away.
Implementation and usage notes:
* General:
Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that. But this is only intended to be used to test Git
itself.
* Perl:
Perl code that wants to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by
default.
Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.
Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.
I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.
* Shell:
Shell code that wants to be localized should use the new
git-sh-i18n library. It's just a wrapper for the system's
gettext.sh.
If gettext.sh isn't available we'll fall back on a dumb
printf(1)-powered fall-through wrapper.
I originally tried to detect if the system supported `echo -n' but
I found this to be a waste of time. My benchmarks on Linux, Solaris
and FreeBSD reveal that printf(1) is fast enough, especially since
we aren't calling gettext() from within any tight loops.
This patch is based on work by Jeff Epler <jepler@xxxxxxxxxxxxxx> who
did the initial Makefile / C work, and a lot of comments from the Git
mailing list.

+
+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.
