For example, when i type:

git checkout <Tab>

It list all they branches on my current git repo. Is this usecase possible with picocli?

thank you for your quick reply, so it's possible then, I will try to learn more about it.

There's JLine and bash completion. Dynamic completion is easier with JLine.

It's possible with bash but you would have to customize the bash completion script generated by picocli. So picocli would only do the first half...

nqminhuit commented 1 week ago

So if I use bash completion, I have to write additional bash functions for the dynamic parts?

Yes probably.
