[Python-ideas] contextmanager for locale

When I generate certain files I have to write a date formated as english text, but the error messages (if there are any) I'd like to keep in the system language. I propose to add this (or a similar) contextmanager:

@contextmanager def localectx(category, newlocale=None): oldlocale = locale.getlocale(category) locale.setlocale(category, newlocale) try: yield finally: locale.setlocale(category, oldlocale)

Example usage:

with localectx(locale.LC_TIME,('en','UTF8')): sdate = time.strftime('%a %b %d %Y')

spec_file.write(''' %%changelog

* %s Maintainer Name maintainer@example.com ''' % sdate)
