// The Unicode Nazi // Once enabled the unicode nazi will complain whenever something is not purely unicode or bytestring. It's annoying as hell and only useful when porting over libraries from Python 2 to Python 3. It has a huge runtime impact on performance and will also complain about most of the stuff in the Python standard library. - usage: >>> import unicodenazi >>> 'foo' == u'foo' __main__:1: UnicodeWarning: Implicit conversion of str to unicode True - how to disable it again: >>> unicodenazi.disable() - and here is how to enable: >>> unicodenazi.enable() - if you want to enable it only for a given block: >>> unicodenazi.disable() >>> with unicodenazi.blockwise(enabled=True): ... assert 'foo' == u'foo' ... __main__:2: UnicodeWarning: Implicit conversion of str to unicode The reverse works too of course. The module can be used from a command line: $ python -municodenazi your_script.py [script_args..]
