# GNOME Terminal Auto Theme Sync
|
||||
|
||||
|
||||
|
||||
Automatically sync your GNOME Terminal theme with your system's light/dark mode preferences.
|
||||
|
||||
## Features
|
||||
|
||||
- 🌓 Automatic theme switching between light and dark modes
|
||||
- ⚡ Instant theme application when system preference changes
|
||||
- 🔄 Background process that monitors system theme changes
|
||||
- 🛠️ Easy installation and uninstallation
|
||||
|
||||
## Installation
|
||||
|
||||
1. **Download the project files**:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/MatMasIt/gnome-terminal-autotheme.git
|
||||
cd gnome-terminal-autotheme
|
||||
```
|
||||
|
||||
2. **Run the installer**:
|
||||
|
||||
```bash
|
||||
./install.sh
|
||||
```
|
||||
|
||||
3. **Follow the prompts** to complete installation.
|
||||
|
||||
The installer will:
|
||||
- Copy necessary files
|
||||
- Set up autostart entry
|
||||
- Start the theme sync service
|
||||
|
||||
## Uninstallation
|
||||
|
||||
To remove the auto theme sync, simply run the installer again.
|
||||
|
||||
You'll be prompted to choose:
|
||||
- Remove just the autostart entry or the whole installation
|
||||
- Whether to keep your terminal in light or dark mode after uninstall
|
||||
|
||||
## Requirements
|
||||
|
||||
- GNOME Desktop Environment (tested on GNOME 40+)
|
||||
- GNOME Terminal
|
||||
- Bash 4.0+
|
||||
|
||||
## Configuration
|
||||
|
||||
Advanced users can edit the theme definitions in: [sync-terminal-theme.sh](sync-terminal-theme.sh)
