[Python-ideas] contextmanager for locale

[Mathias Panzenböck]

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 at example.com>
''' % sdate)
