[mrjones2014]

Fixes: #49

@primeapple Please give this a test.

[mehalter]

@mrjones2014 thanks for this! I gave it a shot and get this error when trying to switch to a split in kitty. I can switch between my neovim splits just fine

[mrjones2014]

@mehalter what Kitty version are you using and did you set it up to allow remote commands? https://github.com/mrjones2014/smart-splits.nvim/pull/50/files#diff-b335630551682c19a781afebcf4d07bf978fb1f8ac04c6bf87428ed5106870f5R334

I can't reproduce your issue.

[mehalter]

Yeah I am, I am actually trying to move directly from https://github.com/knubie/vim-kitty-navigator

[mrjones2014]

can you paste the output (removing anything sensitive, if there is anything) of kitty @ ls when you have multiple kitty splits open?

[mehalter]

This is with a single vertical split:

Ah, probably a difference in Kitty version then. My code is currently looking for tab.is_active_tab but your output shows just tab.is_active. I'll update to check for both so it works for both Kitty versions.

[mehalter]

Ah yeah that makes sense, I am using kitty 0.27.1 created by Kovid Goyal I believe this is the latest version

[mrjones2014]

@mehalter please give it another shot if you don't mind, thanks 🙂

[mehalter]

Dang, I hate to be a nuisance here LOL but I'm getting the same error :(

Not a nuisance at all, I want to get it working 🙂

I updated my Kitty version and can reproduce now, so it should be easier to debug on my end.

[mrjones2014]

@mehalter I had a typo -- try one more time please?

[mehalter]

Works perfectly! Thanks @mrjones2014 !

[primeapple]

Holy guacamole. This was fast.

Will try it in the following days. You might shorten the copied Readme a bit ;-)

Btw: When using the split layout ( https://sw.kovidgoyal.net/kitty/layouts/#the-splits-layout ) in Kitty, it should be possible to work out resizing and paneswapping ;-)

As mentioned here: https://sw.kovidgoyal.net/kitty/layouts/#window-resizing

The window resizing API in Kitty is not directional, it's "taller"/"shorter"/"wider"/"narrower" so directional resizing won't work.

kitty/active_pane.py file is listed in install script but missing from the PR

[mrjones2014]

Thanks for calling that out -- I've removed that line from the install script.
