This application listens for when the macOS interface theme changes and then does some thing(s). For now, it's hardcoded to switching my kitty and Neovim themes to match the new theme.

Ideally the different things themselves would handle this themselves, as others do.

NB: This demo is from a 2012 13" MacBook Pro.

1. Download the latest version from the Releases page.
2. Move it to your path.

1. $ git clone [email protected]:jesse-c/AppearanceNotifier.git
2. $ swift build --configuration release.
3. $ mv .build/x86_64-apple-macosx/release/AppearanceNotifier /usr/local/bin/

You'll need to adapt the respond function for your local machine's setup.

Run the compiled binary (e.g. $ AppearanceNotifier). You'll need to leave this running.

To have it autostart at login, you can use launchd, with the provided job definition. Copy it to the right location (e.g. $ cp com.jesseclaven.appearancenotifier.plist ~/Library/LaunchAgents/).

Neovim

nvim-remote (aka nvr) is used for controlling the Neovim instances.

kitty

For kitty to receive remote commands, you'll need to update your config to have:

allow_remote_control true

kitty / tmux

If you're using kitty with tmux, you'll need to explicitly set the socket that kitty listens on, since if you run the command from within tmux, kitty won't pick up on it.

How you do this depends on how you start kitty.

If you're starting it from the application icon, you need to set the launch arguments in your kitty config folder. For example, in ~/.config/kitty/macos-launch-services-cmdline I have:

--listen-on unix:/tmp/kitty

NB: If you don't open kitty directly from the application (for example, if you're using Raycast), then it won't pick up these launch arguments.

NB: I haven't tested this with more than 1 kitty window.

Emacs

You'll need to have the server running.

Q. What if my laptop is asleep and it passes sunrise/sunset?

A. From what I've observed, my laptop has already switched, or does so immediately, after I directly wake it up.
