Kitty Terminal

Looks like macOS does not read the shell’s RC startup files by default. Even without changing the default, starting Kitty from the GUI (Spotlight, for example) causes the shell inside kitty not to read RC files. What I do is to launch kitty from Terminal.app or iTerm2.app. I don’t remember having such problems on Arch Linux.

If we have a running kitty instance windows, and open another one from the running instance, perhaps by running Ctrl+n or Cmd+n, this new window seems to share some main process because setting a new window tittle to this window also changes the window title on the other window and vice-versa. Also, in this case, there is a single Kitty icon on macOS dock.

I generally have at least two or three windows with a few tabs in each one for each thing I am working on. For example, may day job project and at least my personal dotfiles project. In this case, I don’t want both Kitty windows to be the same "process" or whatever. I want to set window titles independently from each other. At least for now, in macOS, the solution seems to open Kitty from a running shell session:

Here’s a bash script to set the a given title for all kitty windows, which causes the current OS window to have the same title no matter which (non-OS) window or tab is selected.

/../src/cmdline/kitty-set-window-title.bash
