I don't know much about gettext, but the following suggests that most
strings in argparse are properly wrapped:
$ cat localize_argparse.py
import gettext
def my_gettext(s):
return s.upper()
gettext.gettext = my_gettext
import argparse
if __name__ == "__main__":
parser = argparse.ArgumentParser()
parser.add_argument("-V", action="version")
args = parser.parse_args()
$ python localize_argparse.py -h
USAGE: localize_argparse.py [-h] [-V]
OPTIONAL ARGUMENTS:
-h, --help SHOW THIS HELP MESSAGE AND EXIT
-V show program's version number and exit
The workaround for the "-V" option would be to add the help message
explicitly
parser.add_argument("-V", ..., help=_("show..."))
You still have to provide all translations yourself.
