Usage:

dark-mode listen <script> [<args>...]
Listen for theme changes and run the given script.
The new theme, either "dark" or "light" is passed as the last argument to the script.

Example using listen to change terminal theme

Using chriskempson/base16-shell to change the terminal theme, one can use something like

dark-mode base16 --root "${HOME}/.local/share/base16" --light "ia-light" --dark "ia-dark"

To run the dark-mode listener in the background, for instance starting it in .bashrc/.zshrc, you can use

# Only run if using MacOS.
if [[ "$OSTYPE" == "darwin"* ]]; then
    # Don't run withing Tmux or SSH, as it will already be running in the first terminal session.
    if [["${TERM}" != "screen"* &&  ! -n "${TMUX}" ]] && ! [[ -n "${SSH_CLIENT}" || -n "${SSH_TTY}" ]]; then
        (
            # Run dark-mode in the background, removing it from the job list.
            dark-mode base16 --root "${XDG_DATA_HOME}/base16" --light "one-light" --dark "onedark" &
            # Kill dark-mode when the shell exits.
            bash -c "while ps -p $$ 2>&1 1>/dev/null; do sleep 60; done; pkill -P $!" &
        )
    fi
fi
