Run this script from the root of the repository to update all translations from
|
|
transifex.
|
|
It will do the following automatically:
|
|
|
|
- fetch all translations using the tx tool
|
|
- post-process them into valid and committable format
|
|
- remove invalid control characters
|
|
- remove location tags (makes diffs less noisy)
|
|
|
|
TODO:
|
|
- auto-add new translations to the build system according to the translation process
