Suggest completions after argument was "selected"

[moshe5745]

I would like to have completion cycling even if the argument is "selected"
Lets say I have arg1, arg2, arg3, and I choose the first arg1 and press enter.
Right now with my current setup I cant back to "cycling" the args with TAB pressing.

Is this possible with cobra?

This is not a Cobra thing but a shell thing.
I assume you use zsh?
Once you've selected a completion choice, the shell moves on to the next. If you want to go back, you probably have to delete the argument you accepted. Try Escape then backspace.

If I didn't understand, please provide an explicit example of what you are trying to do

Thanks for the fast response.

Yeah i use zsh. But I am building a CLI tool, hopefully for all platforms.

My explicit example is "reexecution of the command with new argument"(Maybe I should call this issue with this).

For instance:

$: ./my_cli_tool command arg_with_long_name

And then pick from the history the last command(arrow up in zsh).
In this situation you need to delete arg_with_long_name and then enter the new one.
So I am looking for a convenient way for it.

So my first idea was to enable the cycling of the options even if one argument is already selected.
My second idea is to somehow make the shell remember the last command without the argument, so when I press arrow up it will write:

$: ./my_cli_tool command

Is it possible?
Any other ideas?

I don’t believe your first idea is possible.
As for the shell remembering the command without the argument, I think what you need is a key binding that’s gonna insert the last command. For example, on my ZSH, typing escape+. will insert the last argument of the previous command. I haven’t found a shortcut to insert the previous command. But if you do, please let me know, this is something I would also like to do be able to do

Beside all this, I don’t believe cobra can help you with this requirement. It’s a shell thing.
