kitty send-text workflow broken by 0.32

[xxyxxyxyx1]

Describe the bug
I have used vim-slime with kitty successfully with kitty versions 0.26 – 0.31. However, on kitty v0.32 and v0.32.1, I have keyboard problems. (Reinstalling v0.31 fixes the problems.)

vim-slime uses a short piece of vimscript to send text from vim to another kitty window, such as an ipython interpreter.

After the first text is sent with vim-slime, most keyboard shortcuts break, along with most uses of the shift key. For example:

• I cannot type symbols requiring shift in vim, such as _; I just get -. I can, however, type capital letters.
• kitty keyboard shortcuts do not work, such as ctrl-tab to switch tabs
• OS shortcuts do not work while kitty is focused, for example cmd-q does not quit kitty. I must use the mouse to quit kitty.

Functionality is restored only after restarting kitty. The vim-slime seems to work as intended, sending text over to the other kitty window as usual.

I am not sure where to start looking for this problem. I posted an issue with vim-slime and was recommended to post here. Any suggestions for tracking down the problem would be appreciated.

I have tried some small manual tests with kitty, to see if I can break it without using vim-slime, but I have not been successful. I tried for example kitty @ --to unix:/tmp/mykitty-1975 send-text --match id:2 --stdin ls, and no keyboard problems occurred.

To Reproduce
Steps to reproduce the behavior:

1. open vim or neovim with the vim-slime plugin
2. send something over slime using a command, <C-c><C-c>, or a different remapped shortcut
3. See error

Additional context

I am starting kitty with kitty --config test.conf and this minimal test.conf:

allow_remote_control yes
listen_on unix:/tmp/mykitty

I am starting neovim with neovim -u test.vimrc and this minimal test.vimrc:

call plug#begin()
Plug 'jpalardy/vim-slime'
call plug#end()
let g:slime_target = "kitty"
let g:slime_default_config = {"listen_on": $KITTY_LISTEN_ON}

Thanks

Works for me running current kitty master with the follwoing steps:

0. Add the following to ~/.vimrc (and add the vim-slime plugin)

   let g:slime_target = "kitty"
   let g:slime_bracketed_paste = 1

1. kitty --config=NONE --listen-on=unix:/tmp/kitty -o allow_remote_control=socket-only -o enabled_layouts=tall --session <(echo "launch vim setup.py\nlaunch ipython")

2. Scroll to some python function and press ctrl-c + ctrl-c in vim
   normal mode

3. Press 2 to select the second window (the one in which ipython is
   running)

4. Accept the value of KITTY_LISTEN_ON as unix:/tmp/kitty

5. Press ctrl-c crl-c again

6. function is pasted as expected in the right hand side ipython window

I did the test on linux, as I dont have all this available in a macOS envoronment but I dont really see any reason to expect it to work differently on macOS

[xxyxxyxyx1]

Thank you very much for testing this yourself.

I compiled kitty from master and followed your steps above exactly. I still have the same problem: the slime works correctly, but afterwards, most keyboard shortcuts are broken. I must use the mouse just to quit the kitty window.

I guess this problem is with either macOS, or something particular to my environment. I will try to reproduce this on a different macOS computer and report back. If you have any other ideas to try please let me know.

I can reproduce this with just kitty @ select-window --self

1. kitty --config=NONE --listen-on=unix:/tmp/kitty -o allow_remote_control=socket-only -o enabled_layouts=tall --session <(echo "launch\nlaunch")
2. kitty @ select-window --self
3. select any window
4. Now see that opening a new tab cmd+t, a new window cmd+enter, or closing kitty cmd+q doesn't work.
5. Open vim, enter insert mode, press shift+3 and 3 is entered, shift+4 and 4 is entered, try quitting vim with :q and observe you can't (because shift+; enters ;).

shift+letter keys work on the other hand, and the shift+num keys work in nano and on the shell prompt just not in vim.

I can also see the following on stdout

[027 12:09:52.605641] [PARSE ERROR] Unrecognized DCS code: 0x7a
[027 12:09:52.605656] [PARSE ERROR] Unknown CSI code: 'm' with start_modifier: '' and end_modifier: '%' and parameters: '0'~~

That's unrelated

I have recompiled kitty from master version 8c12086, and it appears the problem has been fixed! Thank you both. (And thank you for making compiling kitty so effortless to a beginner.)
I will comment again if I find anything is still broken.

@kovidgoyal Thank you for point me to this issue.

May I ask when will be the next release?
As this is affecting my daily workflow, if the next released is not near I will consider using the nightly builds.
