Get selection from an internal command such as "commandline get-selection"

[blindFS]

I'd like to add keybinding features like vim-surround to vi normal mode.
As far as I know, I can't get selected text or copied text (not the system copy/cut) in pure nushell script.
It would be even better if commandline edit support more actions such as those already existed in keybindings list --edits.

I'm guessing that we'd support such a functionality. You can see all the commandline commands now with help commandline in nushell. maybe a commandline set-selection and commandline get-selection to follow the current commands?

Just checked the source code on the main branch. Only get-cursor and set-cursor are implemented. I'd like to have 2-int (start, end) version of them.

Right, I was suggesting that you write some new commands to support the functionality you're describing.

Hi @fdncred , I'd like to discuss the design choice here. Why we use a ReplState instead of just a Reedline editor in struct EngineState? Seems that the set-selection function (or any other feature that requires reedline editor involved) is impossible to implement in trait Command?

I'm not sure. I don't understand reedline's internals enough to help answer.
