Click sub-command name renaming not detected

[Querela]

Hi, I'm using the most current version of Sphinx (3.4.2), Sphinx-Click (latest) and click (7.1.2).

My situation is like this:

• I have a separate package with a click cli, which has a group named main (module modA.cli in package packageA)
• in another package (module modB.cli in package packageB) I also have a CLI and import the group main from modA.cli as submain
• I add the submain group to the modB.cli command groups as a subcommand. If I now execute packageB I will see the subcommand submain as possible choice. In the generated documentation it however will still appear as main (name from modA.cli I would suppose)

Not sure if the example code can reproduce this or if it has to be separate packages (not just modules)...

# packageA modA.cli

import click

@click.group()
def main():
    pass

@main.group()
def subA():
    pass

# packageB modB.cli

import click
from modA.cli import main as submain

@click.group()
def main():
    pass

main.add_command(submain, "submain")  # <-- here I add the commandgroup from packageB and rename the command
# without renaming here, it will show up as `main` in the CLI

@main.group()
def subB():
    pass

I will then call the modB.cli:main() entry point.

Documentation is dead simple:

.. click:: modB.cli:main
  :prog: packageB
  :nested: full

Yeah, this isn't something we currently support. I'm not sure how easy it would be to fix this since we don't fully evaluate the application.

Ok. That makes sense and it guards against some side effects. Is it possible to manually rename the command in the docs? (Also complicated probably because of any possible depth.)

[stephenfin]

Unfortunately not, no

[Querela]

Hmm. It's an internal project. And documentation is currently not done automatically. So maybe just manual postprocessing to update the 5-6 occurrences where it is wrong. Or just a notice somewhere. I can't think of any easy solution/fix for now ...

the renamed names are lost in these lines: https://github.com/click-contrib/sphinx-click/blob/aa0d5b7bcda183d20c7b98a9a1c9acf1e003af97/sphinx_click/ext.py#L285-L288

prior to those lines, for a click.Group, lookup is a dictionary that maps the new names to the click.Command objects. those lines return a list that strips away the new names. perhaps the lookup can be maintained, and the commands can be ordered alphabetically using a OrderedDict (or a list of tuples).

this issue is preventing me from using sphinx-click to document my application.

I'd welcome a pull request to fix this. Please include tests
