Simple cross-platform utility to output what appearance style is used.
Build the tool using cargo build --release and copy it into a location on your $PATH using cp target/release/darklight /usr/local/bin/.
An example of using this to set the theme of the Helix editor dynamically:
if [[ "$(darklight)" == *"Dark"* ]]; then
CATPPUCCINO="mocha"
else
CATPPUCCINO="latte"
fi
CATPPUCCINO_TARGET="${HOME}/.config/helix/themes/catppuccin_${CATPPUCCINO}.toml"
CATPPUCCINO_LINK="${HOME}/.config/helix/themes/catppuccin.toml"
ln -sf $CATPPUCCINO_TARGET $CATPPUCCINO_LINK
