Command + K can't kill buffer in OSX

[tlightsky]

it will be cleared,
but get back when press enter to start a new line

Thanks for giving Zellij a try! I'm personally a little unfamiliar with macos, that's more @qballer and @5c077m4n 's domain, but where are you expecting Command + K to kill a buffer? Are you using something like Emacs? Are you have this issue with a particular program?

[a-kenji]

I think its about the clear command on the terminal. Ctrl+L on Linux.

@tlightsky
This could also depend on your shell, can you please tell us what shell you are running?

[tlightsky]

thanks for amazing fast reply,
I'm using iTerm2

[a-kenji]

Thank you! Can you also please check what output you get from:

echo $SHELL

[tlightsky]

❯ echo $SHELL
/bin/zsh

Cheers!

@a-kenji I hope that the video here is clear, but I (with zsh in iTerm2 on macOS) had the same outputs both in "vanilla" zsh and in the zellij instance - in both I had to hit enter after the cmd+k to make the screen re-appear (and the cntl-L isn't affected)

[a-kenji]

@5c077m4n
So this might be an iTerm2 and zsh interaction?

[5c077m4n]

@a-kenji Actually I think that it's a problem with iTerm2, as in Alacritty cmd+k works exactly like ctrl+l.
Plus in iTerm2 my 2 line prompt also disappears after cmd+k (even outside of zellij)

@5c077m4n
Thank you!

@tlightsky.
It seems that this is an iterm2 issue, can you confirm that?
Do you have a different terminal emulator, where you can try that out?

[tlightsky]

try with osx native terminal:

❯ zellij --version                                                                                                                                      
zellij 0.5.0 

clear works fine,
Cmd+K can clear, but will appear when press any key

[a-kenji]

@tlightsky Is that still and issue on 0.5.1 ?

[tlightsky]

@a-kenji
yes, just tried with 0.5.1

[a-kenji]

@tlightsky thanks!

@tlightsky - I made some input fixes in 0.10.0 as well as properly handling some reporting signals coming from the terminal. Could you give it a try?

If this did not fix it for you, I'd like to ask your help debugging this. It would be useful for me to get some log files so that I can reproduce this problem locally and get to the bottom of it. Could you follow the instructions here and attach the relevant files (especially the pane logs, eg. zellij-3.log): https://github.com/zellij-org/zellij/blob/main/.github/ISSUE_TEMPLATE/bug_report.md

Thanks!

Just wanted to say that this still happens, both when using the native terminal and when using iTerm.

Is there an action that we could map to clear the buffer like Cmd+K on macOS does?

I opened a discussion item around it here:

#1767

And this issue seems to be related.

The expected behavior is moving the last line on the current buffer to the first and clear everything out below it.

[fcoury]

Alright, as I mentioned on the discussion thread, I have been able to implement something that behaves exactly like Cmd+K on iTerm and Terminal.app. I also added a configuration option to optimize the offset when clearing the panel. In this case I mapped it on my configuration file as Ctrl+P Ctrl+L.

    pane:
        - action: [SoftClear, SwitchToMode: Normal,]
          key: [Ctrl: 'l']

Would love to get some feedback on the PR #1768.
