This code is adapted from the elib.intl module available on GitHub at
|
|
https://github.com/dieterv/elib.intl, commit 49d5797 on 1 Sep 2017.
|
|
|
|
It has been stripped down to the necessary code for UI localization
|
|
using Gtk.Builder in gPodder on Windows (msys2) and adapted to python 3.
|
|
|
|
The elib.intl module provides enhanced internationalization (I18N) services for
|
|
your Python modules and applications.
|
|
|
|
This module adds the following on Microsoft Windows systems:
|
|
|
|
- automatic detection of the current screen language (not necessarily the same
|
|
as the installation language) provided by MUI packs,
|
|
- makes sure internationalized C libraries which internally invoke gettext() or
|
|
dcgettext() can properly locate their message catalogs. This fixes a known
|
|
limitation in gettext's Windows support when using eg. gtk.builder or gtk.glade.
|
|
|
|
See http://www.gnu.org/software/gettext/FAQ.html#windows_setenv for more
|
|
information.
