Up- and Down- Arrow should consider entered text

[Flare576]

When I type in a partial command and press ⬆️, I expect to only see historical commands starting with my partial. Example:

> cd /a/really/long/path
> ls
> cd /another/really/long/path
> ls
> cd /a/ ⬆️

I'd expect the line to now have cd /a/really/long/path, but it actually has ls

This will be a feature for rustyline.

@Flare576 Does the right-arrow completion work for you? Or ctrl-r?

I agree that this would be nice too, and also that it's an upstream issue.

[provjeremys]

@wycats Right-arrow completion does take the value displayed in white and enter it as the current command. I'm 99.9% sure we're on the same page, but just to future-proof this issue: my request would be to, essentially, filter the history based on the already entered partial command, not just maintain the right-arrow functionality.

Is there an update on this? I'm very used to typing the beginning of a command and using arrow-up a few times to find a command in my history from the zsh feature and would love to see it in nushell.

If you can give me some hints I'm willing to implement this feature and create a PR.

@oberien - we currently use https://github.com/kkawakam/rustyline to do our line editing. If it gets implemented there, we should be able to add it nushell. You might want to file an issue on that repo and see if it's being worked on. The bonus is that other people using rustyline would also benefit.

Why won't they accept the pull request?
Maybe nu should (temporarily?) switch to a rustyline fork.

Solved with the history traversal behavior of reedline

[felschr]

I have slightly different case, where I'd like arrow up to match commands that contain the text I've entered, not just commands that start with the text.
e.g. when I enter rebuild, then press arrow up, I'd expect it to match sudo nixos-rebuild switch from my history.

I'm currently running nushell 0.71.0, but I also couldn't find any mention of this feature in any following release notes.
