GNOME Auto Dark Mode Switcher

This Rust utility automatically switches between light and dark GNOME themes based on specified time spans utilizing gsettings command-line tool.

Features

• Automatically switches between predefined light and dark themes.
• User-configurable switch times via a YAML configuration file.
• Periodically checks the current time to determine the theme to be set.

Dependencies

• chrono: For working with time.
• serde: Serialization and deserialization library.
• serde_yaml: For parsing and serializing YAML.
• serde_derive: Macros for automatically deriving Serialize and Deserialize traits.

Configuration

The configuration file is located at ~/.gnome-ad-config.yaml.

Example configuration:

schedule_light_mode: "07:00"
schedule_dark_mode: "19:00"
cycle_rate_seconds: 600

theme:
  light_gtk_theme: Flat-Remix-GTK-Blue-Light-Solid
  dark_gtk_theme: Flat-Remix-GTK-Blue-Dark-Solid
  light_color_theme: prefer-light
  dark_color_theme: prefer-dark

• schedule_light_mode: The time to switch to the light theme.
• schedule_dark_mode: The time to switch to the dark theme.
• cycle_rate_seconds: How often (in seconds) the program checks the current time and updates the theme.

Usage

cargo build --release && ./target/release/gnome_auto_dark

Simply run the compiled binary. The tool will check the time against the specified schedule in the configuration file and set the GNOME theme accordingly.
