- Add class method availableTranslations() to AbstractFormatHandler in
i18n.py.
- Use it in fg-update-translation-files to allow autodetection of the
available translations when no LANGUAGE_CODE is passed to
fg-update-translation-files.
This should address James' wish at
<https://sourceforge.net/p/flightgear/mailman/message/37003967/>.
- Remove unnecessary imports
These imports were a leftover from early versions; now, they are done
in modules such as flightgear.meta.i18n and don't need to be in the
calling scripts anymore.
- Fix an exception message
Add the following files:
python3-flightgear/README-l10n.txt
python3-flightgear/fg-convert-translation-files
python3-flightgear/fg-new-translations
python3-flightgear/fg-update-translation-files
python3-flightgear/flightgear/__init__.py
python3-flightgear/flightgear/meta/__init__.py
python3-flightgear/flightgear/meta/exceptions.py
python3-flightgear/flightgear/meta/i18n.py
python3-flightgear/flightgear/meta/logging.py
python3-flightgear/flightgear/meta/misc.py
They should work on Python 3.4 and later (tested with 3.5.3). The folder
structure is chosen so that other FG support modules can insert
themselves here, and possibly be used together. I put all of these
inside 'flightgear.meta', because I don't expect them to be needed at FG
runtime (neither now nor in the future), probably not even by the CMake
build system.
To declare that a string has plural forms, simply set the attribute
'with-plural' to 'true' on the corresponding element of the default
translation (and as in Qt, use %n as a placeholder for the number that
determines which singular or plural form to use).
