Steps to reproduce the bug with the above code

Use this .yaml for any command line parsing.

Actual Behaviour

When calling the binary like pdbman -QY it fails with error: The argument '--query' cannot be used with '--analyze'. However the same is not true if I call multiple arguments from other groups like so: pdbman -Aqo or pdbman -Qrt. These commands run without error. It appears that only the args from the topmost group in the YAML file are recognized as being mutally exclusive. I verified this by changing their order.

Expected Behaviour

I would expect a command calling arguments from the same group to also fail with this: error: The argument '--residues' cannot be used with '--atoms' if they belong to the same group.

Additional Context

No response

Debug Output

No response

[pksunkara]

Need the command which is failing and the debug output.

[pksunkara]

Basically, the "actual behaviour" sections need actual command runs and their outputs.

[DocKDE]

I updated the section for expected and actual behaviour. Although I must add I'm not sure what you mean by failing commands and debug output. My issue is precisely that there is no failing command when I expected it so there's no debug output I can post.

[pksunkara]

What you wrote now is good.

@DocKDE Can you please try with the latest master now?

We have decided to deprecate the YAML API. For more details, see #3087. If there is interest in a YAML API, it will likely be broken out into a clap_yaml and developed independent from the core of clap.
