Yet another question about completions

[allanger]

Oi!
I am currently developing a cli tool with Сlap and I've got a request about creating completions for zsh. But I can't understand how to implement it in the way I expect it to work. Example:

There is an argument --user-id which is being parsed into u64 And as I understand it's possible to make it look like this:

$ gum ... --user-id # Pressing Tab here
1 2 3 4

But these ids won't really help the user. Because nobody really remembers them. So for me, it would make much more sense to make it work like this:

$ gum ... --user-id # Pressing Tab here
1 - User Name ([email protected])
2 - Another User ([email protected])

The tool is working with YAML files and with Gitlab, so these values (ids, names, emails, etc) can be taken from these sources.

Is it possible to do something like that?

At the moment, clap supports compeleting

• Flags and subcommands
• value-hints
• static enumerated values

The static enumerates values (possible_values / ArgEnum) support help text with them (PossibleValue::help) which will show up in completions that support it.

We do not have support for dynamic completions yet, see #1232. I'll make a note on that issue so we don't forget help text for dynamic completions.
