#!/usr/bin/env fish # # This script was originally motivated to work around a quirk (or bug depending on your viewpoint) # of the xgettext command. See https://lists.gnu.org/archive/html/bug-gettext/2014-11/msg00006.html. # However, it turns out that even if that quirk did not exist we would still need something like # this script to properly extract descriptions. That's because we need to normalize the strings to # a format that xgettext will handle correctly. Also, `xgettext -LShell` doesn't correctly extract # all the strings we want translated. So we extract and normalize all such strings into a format # that `xgettext` can handle. # This regex handles descriptions for `complete` and `function` statements. These messages are not # particularly important to translate. Hence the "implicit" label. set implicit_regex '(?:^| +)(?:complete|function) .*? (?:-d|--description) (([\'"]).+?(?<!\\\\)\\2).*' # This regex handles explicit requests to translate a message. These are more important to translate # than messages which should be implicitly translated. set explicit_regex '.*\( *_ (([\'"]).+?(?<!\\\\)\\2) *\).*' mkdir -p /tmp/fish/implicit/share/completions /tmp/fish/implicit/share/functions mkdir -p /tmp/fish/explicit/share/completions /tmp/fish/explicit/share/functions for f in share/config.fish share/completions/*.fish share/functions/*.fish # Extract explicit attempts to translate a message.
