Shared options and flags between commands

Question

Say my CLI utility has three commands: cmd1, cmd2, cmd3

And I want cmd3 to have same options and flags as cmd1 and cmd2. Like some sort of inheritance.

@click.command() @click.options("--verbose") def cmd1():     pass  @click.command() @click.options("--directory") def cmd2():     pass  @click.command() @click.inherit(cmd1, cmd2) # HYPOTHETICAL def cmd3():     pass 

So cmd3 will have flag --verbose and option --directory. Is it possible to make this with Click? Maybe I just have overlooked something in the documentation...

EDIT: I know that I can do this with click.group(). But then all the group's options must be specified before group's command. I want to have all the options normally after command.

cli.py --verbose --directory /tmp cmd3 -> cli.py cmd3 --verbose --directory /tmp

I have found a simple solution! I slightly edited the snippet from https://github.com/pallets/click/issues/108 :

import click   _cmd1_options = [     click.option('--cmd1-opt') ]  _cmd2_options = [     click.option('--cmd2-opt') ]   def add_options(options):     def _add_options(func):         for option in reversed(options):             func = option(func)         return func     return _add_options   @click.group() def group(**kwargs):     pass   @group.command() @add_options(_cmd1_options) def cmd1(**kwargs):     print(kwargs)   @group.command() @add_options(_cmd2_options) def cmd2(**kwargs):     print(kwargs)   @group.command() @add_options(_cmd1_options) @add_options(_cmd2_options) @click.option("--cmd3-opt") def cmd3(**kwargs):     print(kwargs)   if __name__ == '__main__':     group()
