Kitty / foot color scheme only effective upon applying scheme (some sort of side effect?)

[yao-yun]

Although I couldn't find any kitty-related configuration in the dotfiles repository, nor any guidance on setting it up, and I assume it's not supported, this behavior is also present with foot.

When switching to a dynamic dark or light theme (for example, dark mode), the color scheme of all already open kitty/foot terminal windows changes to the left as shown below. However, newly opened windows continue to use the original theme.

I expect the color scheme to either not change at all, or to be applied all the time, and the former would be better. How can I achieve either of these behaviors?

TL;DR

Caelestia themes terminal with escape sequence instead of dedicated configurations for every terminal emulators.

The escape sequence is generated in ~/.local/state/caelestia/sequences.txt.
Add cat ~/.local/state/caelestia/sequences.txt 2> /dev/null (fish, from caelestia dots) or an equivalent command in your shell's source to use it.

The colour scheme should be sourced on fish shell startup, so if you do not start a fish shell it won't be coloured.

[yao-yun]

Thx. I forgot to source the color scheme file

BTW anyone who has aliased cat to batcat or anything else shall probably use the gnu cat. @soramanew Or maybe /bin/cat / /bin/env cat can be used in the script instead?)

[soramanew]

Hmm, I don't really know if it should be hard coded though

I also have this problem. Although the question is answered, I can't seem to find the template that caelestia shell generates for kitty or am I blind?

Yeah, it does not generate colors for kitty, at first I thought of writing shell script to get caelestia scheme get into kitty as workaround but then ended up opening a PR for kitty support caelestia-dots/cli#79

Hmm, the colour theming should work for all terminals running fish though?

It does not because caelestia themes terminal emulators through ASCII control sequences, provided in this file ~/.local/state/caelestia/sequences.txt .

You need to include this line https://github.com/caelestia-dots/caelestia/blob/main/fish%2Fconfig.fish#L36 (or an equivalent one) in your shell's source for theming if you are not using caelestia dots but only caelestia shell.
