Hello, I use argparse from Python 3.3.3 with a custom action that normalizes path arguments:
http://docs.python.org/3/library/argparse.html#action def norm_path(*parts): """ Returns the normalized, absolute, expanded and joined path, assembled of all parts. """ parts = [ str(p) for p in parts ] return os.path.abspath(os.path.expanduser(os.path.join(*parts))) # Taken from the docs class NormPath(argparse.Action): def __call__(self, parser, namespace, values, option_string=None): print('%r %r %r' % (namespace, values, option_string)) setattr(namespace, self.dest, norm_path(values)) def parse_args(): parser = argparse.ArgumentParser() parser.add_argument("--config", help="Path to config file.", default = "~/.foobar/config", action=NormPath) return parser.parse_args() This works fine when there is actually a --config=path supplied. But it's not being applied on default arguments. Of course, I could use "default = norm_path('~/.foobar/config')" but I expect that custom actions are applied to default values as well. The store action works alike for default and supplied values. What do you think? Florian -- https://mail.python.org/mailman/listinfo/python-list
