Conan: Py3: Commands with subarguments do and say nothing if no params are entered

[lasote]

Run: conan editable, conan config, conan remote, conan profile, conan workspace...
In general all the commands with sub arguments. They should show the help.

$conan editable

usage: conan editable [-h] {add,remove,list} ...
conan editable: error: too few arguments
ERROR: Exiting with code: 2

$ conan config

usage: conan config [-h] {rm,set,get,install} ...
conan config: error: too few arguments
ERROR: Exiting with code: 2

They show the help they have with their subcomands, I don't understand very well this issue.

(conan_use) luism@luism-MacBookPro:~/workspace/conan$ conan editable
(conan_use) luism@luism-MacBookPro:~/workspace/conan$ conan workspace
(conan_use) luism@luism-MacBookPro:~/workspace/conan$

For info: I am running Windows, both from source and from pip install package works the same.

Ok, the difference is py3. In py2 it is working fine.

Hi!
I reproduced this Issue and seems like this is what's happening: https://bugs.python.org/issue9253#msg186387 so setting subparsers.required = True makes it work the same in both Py2 and Py3:

    def editable(self, *args):
        """ Manage editable packages
        """
        parser = argparse.ArgumentParser(description=self.editable.__doc__,
                                         prog="conan editable")
        subparsers = parser.add_subparsers(dest='subcommand', help='sub-command help')
        subparsers.required = True

I hope this helps!

Thanks so much!
