tenki is a terminal clock that combines a large digital time display with animated weather-style effects. Its name is the Japanese word for weather. The program is built with Ratatui and offers a visually distinctive alternative to a conventional terminal clock.
The clock can be paired with rain, snow, or meteor animations, or the effect can be disabled entirely. Behaviour is controlled from command-line options, including animation intensity, wind direction, frame rate, tick rate, colour, and display behaviour.
This is free and open source software.
Key Features
- Displays a large digital clock directly in the terminal.
- Offers rain, snow, and meteor animation modes.
- Lets you disable the weather effect for a simpler clock display.
- Provides a DVD-style timer mode.
- Supports selectable timer colours including red, green, blue, and white.
- Lets you set the animation frame rate and tick rate independently.
- Offers an adjustable effect level, allowing the animation intensity to be changed.
- Provides several wind modes, including random, left, right, one-direction-only, and disabled.
- Can display the current frames-per-second counter.
- Supports a blinking colon in the clock display.
- Uses Ratatui for the terminal user interface and Crossterm for terminal interaction.
- Can be installed directly with Cargo.
- Can be built from source using the supplied Makefile.
- Available to Arch Linux users through the AUR.
- Uses Chrono for time handling and Clap for command-line argument parsing.
- Includes configurable runtime controls without requiring a graphical desktop environment.
