Plumbing strings should not be translated, since + they're part of Git's API. + + - Adjust the strings so that they're easy to translate. Most of the + advice in `info '(gettext)Preparing Strings'` applies here. + + - If something is unclear or ambiguous you can use a "TRANSLATORS" + comment to tell the translators what to make of it. These will be + extracted by xgettext(1) and put in the po/*.po files, e.g. from + git-am.sh: + + # TRANSLATORS: Make sure to include [y], [n], [e], [v] and [a] + # in your translation. The program will only accept English + # input at this point. + gettext "Apply? [y]es/[n]o/[e]dit/[v]iew patch/[a]ccept all " + + Or in C, from builtin/revert.c: + + /* TRANSLATORS: %s will be "revert" or "cherry-pick" */ + die(_("%s: Unable to write new index file"), action_name(opts)); + +We provide wrappers for C, Shell and Perl programs. Here's how they're +used: + +C: + + - Include builtin.h at the top, it'll pull in in gettext.h, which + defines the gettext interface. Consult with the list if you need to + use gettext.h directly. + + - The C interface is a subset of the normal GNU gettext + interface. We currently export these functions: + + - _() + + Mark and translate a string. E.g.: + + printf(_("HEAD is now at %s"), hex); + + - Q_() + + Mark and translate a plural string. E.g.: + + printf(Q_("%d commit", "%d commits", number_of_commits)); + + This is just a wrapper for the ngettext() function. + + - N_() + + A no-op pass-through macro for marking strings inside static + initializations, e.g.: + + static const char *reset_type_names[] = { + N_("mixed"), N_("soft"), N_("hard"), N_("merge"), N_("keep"), NULL + }; + + And then, later: + + die(_("%s reset is not allowed in a bare repository"), + _(reset_type_names[reset_type])); + + Here _() couldn't have statically determined what the translation + string will be, but since it was already marked for translation + with N_() the look-up in the message catalog will succeed. + +Shell: + + - The Git gettext shell interface is just a wrapper for + gettext.sh. Import it right after git-sh-setup like this: + + . git-sh-setup + . git-sh-i18n + + And then use the gettext or eval_gettext functions: + + # For constant interface messages: + gettext "A message for the user"; echo + + # To interpolate variables: + details="oh noes" + eval_gettext "An error occured: \$details"; echo + + In addition we have wrappers for messages that end with a trailing + newline. I.e. you could write the above as: + + # For constant interface messages: + gettextln "A message for the user" + + # To interpolate variables: + details="oh noes" + eval_gettextln "An error occured: \$details" + + More documentation about the interface is available in the GNU info + page: `info '(gettext)sh'`. Looking at git-am.sh (the first shell + command to be translated) for examples is also useful: + + git log --reverse -p --grep=i18n git-am.sh + +Perl: + + - The Git::I18N module provides a limited subset of the + Locale::Messages functionality, e.g.: + + use Git::I18N; + print __("Welcome to Git!\n"); + printf __("The following error occured: %s\n"), $error; + + Run `perldoc perl/Git/I18N.pm` for more info. + + +Testing marked strings +---------------------- + +Even if you've correctly marked porcelain strings for translation +something in the test suite might still depend on the US English +version of the strings, e.g. to grep some error message or other +output. + +To smoke out issues like these Git can be compiled with gettext poison +support, at the top-level: + + make GETTEXT_POISON=YesPlease + +That'll give you a git which emits gibberish on every call to +gettext. It's obviously not meant to be installed, but you should run +the test suite with it: + + cd t && prove -j 9 ./t[0-9]*.sh + +If tests break with it you should inspect them manually and see if +what you're translating is sane, i.e. that you're not translating +plumbing output. + +If not you should replace calls to grep with test_i18ngrep, or +test_cmp calls with test_i18ncmp. If that's not enough you can skip +the whole test by making it depend on the C_LOCALE_OUTPUT +prerequisite.
