This adds feature parity for mangen with the standard help output. Users will now see the list of possible values for value arguments. One change that was made to make this possible was adding the method `get_possible_values` to the public API for an arg. I tried to think of a way to get around this, but because this is the interface that the help generation uses, and it is part of the crate public interface I thing adding it as a part of the public API might be for the best. fixes: clap-rs#3861
This makes sure we take into account the setting that possible args is hidden
Noticed that possible values would not show up for Positional arguments as well. Decided to add the changes for those as well.

Thanks! This was made against master which is v4. If you would like, you are welcome to cherry-pick this onto v3-master. |
