[Qgis-developer] Fwd: Re: Processing algorithm's groups and names translation.

Thu Jul 16 08:33:12 PDT 2015

I've made a pull request here : https://github.com/qgis/QGIS/pull/2213

With the strategy to produce a python file which calls 
QCoreApplication.translate with each string (names, groups).

Could you give me a feedback about this.

Best regards

Arnaud
