GenerateCompletion command only works if used as direct subcommand of root

[charphi]

I'm trying to use it in a sub-subcommand such as mycommand setup generate-completion
instead of mycommand generate-completion

Unfortunatly, this generates autocompletion for setup and not mycommand.

Yes, currently the AutoComplete.GenerateCompletion command generates completions for its parent. I agree that it would be better if it would generate completions for the root command instead.

Will you be able to provide a pull request (with test) for this?

The implementation for this is fairly straightforward: just replace

String script = AutoComplete.bash(
        spec.parent().name(),
        spec.parent().commandLine());

with

String script = AutoComplete.bash(
        spec.root().name(),
        spec.root().commandLine());

But we do need some tests to verify that this works for your use case (and perhaps another one where the completion command is nested even deeper).

The code is simple indeed.

But, there is one thing missing: a pre-defined variable for root name (ROOT-COMMAND-NAME?) so that the command description
"Generate bash/zsh completion script for ${PARENT-COMMAND-NAME:-the parent command of this command}."
would become:
"Generate bash/zsh completion script for ${ROOT-COMMAND-NAME:-the root command of this command}."

[remkop]

Yes, it makes sense to add a ${ROOT-COMMAND-NAME} variable.
