genstrings this GitHub project that provides python scripts that make genstrings little smarter.
Since I don’t like only link-links (links may die), I will also write a python script here (all credits are transferred to the author of the linked project)
#!/usr/bin/env python # -*- coding: utf-8 -*- # Localize.py - Incremental localization on XCode projects # João Moreno 2009 # http://joaomoreno.com/ # Modified by Steve Streeting 2010 http://www.stevestreeting.com # Changes # - Use .strings files encoded as UTF-8 # This is useful because Mercurial and Git treat UTF-16 as binary and can't # diff/merge them. For use on iPhone you can run an iconv script during build to # convert back to UTF-16 (Mac OS X will happily use UTF-8 .strings files). # - Clean up .old and .new files once we're done # Modified by Pierre Dulac 2012 http://friendcashapp.com # Changes # - use logging instead of print # Adds # - MIT Licence # - the first parameter in the command line to specify the path of *.lproj directories # - an optional paramter to control the debug level (set to info by default) # Fixes # - do not convert a file if it is already in utf-8 # - allow multiline translations generated by genstrings by modifing the re_translation regex # - # MIT Licence # # Copyright (C) 2012 Pierre Dulac #
