Use in activities
To make easier the use in the activities, we have a python library and the resources packaged in rpms.
You can download the last versions here:

- If audio file is not available, get_audio_filename() return None
To update translations or create new languages, you can do:
where "lang" is your two letters language code.
You will see the screen displayed here, and can select in the list of words at the left the word to translate, the image will be displayed at the right, and you can add your translation in the input at the bottom. The change is accepted pressing Enter or clicking in the small arrow at bottom right.
When you close the utility, a file words_lang.json will be created in the directory where you are placed. If you want your activity use it, need create a directory "data" and put the file inside. If you interrupt your translation session, and start again, copy the generated file in the 'data' directory. This is not done by the utility to avoid damaging data accidentally. We would like get updated files and add them to the rpms to distribute them. Please send them to godiard at sugarlabs dot org.
