ttog

Short for a Terminal toggle, it's a small Bash utility for automatically applying your preferred light and dark colour scheme pair -organic to the system (e.g. GNOME, Tango, and Solarized)- to your Terminal which follows your current system appearance (light or dark) once you open a new Terminal window.

The colour pair is initially chosen by you via ttog setup, the Use colours from system theme is unticked and no palette is imposed.

Features

• Applies saved colours silently
• Disables GNOME Terminal's automatic system-theme colours for the managed profile before applying the saved pair
• Refuses to save identical light and dark colour pairs
• Leaves other Terminal profiles untouched
• Reports missing configuration instead of modifying Terminal settings
• Rejects unsupported GNOME appearance values.
• Development includes a test suite to quickly confirm refactoring.

Important: the default Terminal profile

ttog setup always reads the colours from the GNOME Terminal profile that is default at the moment setup is performed.

ttog then saves that profile's ID together with the colour pair to a

~/.config/terminal-toggle/config

Later, running ttog operates on that saved profile rather than whichever profile happens to become the GNOME Terminal default afterwards.

Therefore, choose the Terminal profile and its light/dark appearance you want to control BEFORE running ttog setup light / ttog setup dark.

See INSTALL.md/OR ELSEWHERE for the complete setup scenario.

Requirements

• Ubuntu 22(???) / Linux with GNOME Terminal
• Bash
• gsettings

Installation

Maybe it's wiser to include the entire installation right here vs creating a separate INSTALL.md or is the latter gonna be huge for this? We'll see tho

Usage

Once installed and configured as detailed above, simply open a new Terminal window and it should be light or dark as your current system appearance.

In case you need to resave another colour pair for your current default GNOME Terminal profile or you need ttog operating under another default profile, re-do the setup steps from above.

Uninstall

Remove the installed command:

sudo rm /usr/local/bin/ttog

The user's configuration remains in:

~/.config/terminal-toggle/

Remove it separately if desired.
