Commands that are a substring of the functions they call? about argh HOT 4 CLOSED

I think you mean this:

from argh import alias

@alias('spam')
def do_spam(args):
    print 'Albatross!!!'

If not, please reopen the issue and clarify the use case.

Couple things:

• I think your example would add both do_spam and spam. I need the function name to be do_spam but the parser to recognize only spam from input, but call the correct function.
• I have a class with lots of do_* methods. I want to have the parser automatically “know” that command should call do_command without having to specify this each time.

• Actually at this point {{{@alias}}} renames the command, see the [[http://packages.python.org/argh/reference.html#argh.decorators.alias|documentation]]. It is true that the decorator's name is currently a bit misleading.
• I think this is a marginal case that requires your class to do some extra work, e.g. have a method that returns a list of commands like this:

from argh import ArghParser, alias, arg

class App:

    @arg(...)
    def do_x(self): pass

    @arg(...)
    def do_y(self): pass

    def get_commands(self):
        names = [name for name in self.__dict__ if name.startswith('do_')]
        for name in names:
            meth = getattr(self, name)
            yield alias(name[3:])(meth)

    def dispatch(self, argv):
        parser = ArghParser()
        parser.add_commands(self.get_commands())
        parser.dispatch(argv)

I don't see any reason why this issue should stay open. Please correct me if I'm wrong.
