Kitty: Kitty remote control from neovim

[knubie]

Trying to call kitty @ new-window from neovim, but running into some issues.

I believe it's related to this issue, because it works fine with vim.

:!kitty @ new-window from neovim outputs the following:

:!kitty @ new-window
Traceback (most recent call last):

:!kitty "@ new-window" outputs:

:!kitty "@ new-window"
 new-window is not a known command. Known commands are: close-tab, close-window, focus-tab, focus-window, get-colors, get-text, goto-layout, kitten, last-used-layout, ls, new-wi

and :call system("kitty @ new-window") just doesn't do anything.

kitty @ works via a tty device by default. If you have no tty device, which I assume is the case with neovim, you will need to setup a dedicated socket for it. See the --help of the --to option for kitty @ and the --listen option for kitty.

Thanks @kovidgoyal that works. This might be a silly question, but; how can I run kitty with options without keeping a second terminal open? Right now I'm running kitty --some-options from... kitty, which launches another instance of kitty, and if I close the first one, it closes the second one as well.

[kovidgoyal]

create an alias or a launch script or if you are on macOS use the cmdline facility described in the kitty FAQ

I ended up writing this vim plugin: vim-kitty-navigator. Maybe someone will find it useful.
