AppleScript for using Kitty in Alfred. This was made for bash, but can easily be made to work with any shell.

alfred-kitty.scpt

(* 2019-06-07: Added nohup and output redirection to fix a bug with "Open Terminal here" feature. 
		Thanks to @fools-mate for bringing the issue to my attention. *)
on alfred_script(q)
	do shell script "cd ~; nohup /Applications/kitty.app/Contents/MacOS/kitty /bin/bash -c \"source ~/.bashrc && " & q & ";/bin/bash\" > /dev/null 2>&1 &"
end alfred_script

I just came across this gist as I was trying to set up this functionality in Alfred, however when I tried using it, it kept splitting my active terminal instead of opening a new tab. I did some digging and it turns out that the new-window command is deprecated, replaced by the launch command. Here's the snippet that I was able to come up with that opens a new tab instead of splitting the current one.

on alfred_script(q)
    tell application "kitty" to activate
    tell application "System Events"
        repeat until (exists file "/tmp/mykitty.sock")
            delay 6
        end repeat
    end tell
    do shell script "/Applications/kitty.app/Contents/MacOS/kitty @ --to unix:/tmp/mykitty.sock launch --type=tab"
    tell application "System Events" to keystroke q
    tell application "System Events"
        key code 36 -- enter key
    end tell
end alfred_script

In addition to this, you will need to ensure that allow_remote_control yes is present in your ~/.config/kitty/kitty.conf file, and then also create a new file at ~/.config/kitty/macos-launch-services-cmdline which contains the following:

--listen-on unix:/tmp/mykitty.sock

This macos-launch-services-cmdline file is specific to the Mac version of kitty and specifies launch arguments to use, which is the only way I was able to get it to create the necessary socket file for remote control.
