description in `SubParser`s

[kopp]

Is it possible to specify some kind of description of the sub-command?

For example in the example I would like to tell the user what <program> foo start will do, what <program> foo stop will do etc.

I searched for a parameter to tap.SubParser like description but found none. Other "natural" choices where to place such a description were (in my opinion)

• the docstring of the business logic functions (e.g. run_foo_start here ) (as click does it)
• the docstring of the argument class derived from TypedArgs (e.g. FooStartArgs here )

Yes, this is a frequently requested feature, just requested in the lasted opened issue #32 as well.

I've just added some minimal support in #34 which adds:

• help in subparsers
• description in subparser groups

That's basically what argparse allows. I hope this resolves the issue?

New version 0.2.8 is available now on PyPI.
