A while back, Ned Batchelder wrote about poxx.py which he wrote that generates a completely translated .po file to help find strings in his apps that weren't being translated.
We on the Miro dev team had a similar need. Additionally, we have the problem where in some languages, the translated string is longer than the English version and that creates some sizing issues in the ui code.
I took Ned's poxx.py, fixed some issues I had with it, then rewrote the transform to do something reminiscent of what the Swedish Chef would say. The transform has the following properties:
