Delete key doesn't work in kitty mode

[MrPandir]

I get the  character (U+F728) when I press fn + backspace. I expect this to match delete as it does without the kitty protocol.

This is probably the same problem as #194, this also needs to be applied in the kitty protocol.

@MrPandir could you test with latest main?

Still reproducible.

To test, I run the command kitten show-key -m kitty and press fn + backspace. Although this shows that the DELETE PRESS key was pressed, adding the character makes programs think that it is just a character and not a key was pressed.

Kitty

DELETE PRESS
CSI 3 ~

DELETE RELEASE
CSI 3 ; 1 : 3 ~

Rio (head c88f9e4)

DELETE PRESS 
CSI 3 ; 1 ; 63272 ~

DELETE RELEASE
CSI 3 ; 1 : 3 ~

ENTER is from command input, kitty absorbs it, this is also a problem, but it is not related to this issue.

ENTER RELEASE
CSI 13 ; 1 : 3 u

Ah ok, so the issue only happens if you press along with Fn right

@MrPandir could you test again? I think I understood the issue.

Not sure what the problem is, but I'm using nushell and it still somehow gets that character. It doesn't show up in kitty terminal. 🤔

In order not to install nushell you can use docker:

docker run --rm -ti hustcer/debian-nu:0.97-node.20.17.lts

Enable kitty protocol:

$env.config.use_kitty_protocol = true

And you can use keybindings listen, also if you just type fn + backspace in the input field it will also appear.

Hmm weird, I am pressing fn+backspace and don't get the character. 🤔

(Is this only happening when running with docker?)

[raphamorim]

sorry forgot to share with keybindings listen

[MrPandir]

It seems you forgot to enter $env.config.use_kitty_protocol = true before testing. Because by default nushell does not use kitty protocol. That's why you get normal behavior.

(Is this only happening when running with docker?)

No, I use nushell as a shell on Mac, and I provided the docker commands, in case you don't like cluttering your computer with utilities you don't use. 😁

In the main branch the kitty protocol is enabled by default. I am trying to fix the remaining issues to enable it for next version. 🙏

Kitty protocol is disabled by default. The use of the kitty protocol must be enabled in the config, or at the beginning of the session, enter the command that I wrote above. https://github.com/nushell/nushell/blob/main/crates/nu-utils/src/sample_config/default_config.nu#L266

I see, thought it was use-kitty-protocol-keyboard from Rio. I tried to switch the config in nu but got this message:

Do you have an idea what could it be?

You may be using an old version of nushell. And also you have not updated the config, as critical changes are made to it. 🤔Simple solution: update to the latest version and delete the config. The config is located at $nu.config-path

[raphamorim]

I pushed many refactors to main branch, fixed some weird stuff, could you test again?

[raphamorim]

Looks it fixed

Closing this issue for now, thank you!

It's working. Thank you very much. ❤️
