Bash scripts can now easily internationalized with gettext.
Here's how:
Indicate the package's name when the scripts starts by adding a...
TEXTDOMAIN=package_name
Mark any internationalizable string this way:
before: echo "Hello"
after : echo $"Hello"
That tells bash (2.0) to look for those strings in the corresponding file
(/usr/share/aa/LC_MESSAGES/package.mo).
xgettext won't extract i18n messages from scripts. Bash has an included
feature to do so, but I find it unusable. So I'm enclosing a script (with a
little of Perl) to extract messages from scripts.
Then you may use the other gettext utilites, as msgmerge and msgfmt.
If you want to see a working example, download the new `bug' source
archive.
Bye...! Let's internationalize Debian!
