tui-rs is a Rust library to build rich terminal
user interfaces and dashboards. It is heavily inspired by the
library blessed-contrib and the
Go library termui.
The library supports multiple backends:
The library is based on the principle of immediate rendering with intermediate
buffers. This means that at each new frame you should build all widgets that are
supposed to be part of the UI. While providing a great flexibility for rich and
interactive UI, this may introduce overhead for highly dynamic content. So, the
implementation try to minimize the number of ansi escapes sequences generated to
draw the updated UI. In practice, given the speed of
Rust the overhead rather
comes from the terminal emulator than the library itself.
Moreover, the library does not provide any input handling nor any event system and you may rely on the previously cited libraries to achieve such features.
I'm actively looking for help maintaining this crate. See this issue
Rust version requirements
Since version 0.17.0,
tui requires rustc version 1.56.1 or greater.
The demo shown in the gif can be run with all available backends.
# crossterm cargo run --example demo --release -- --tick-rate 200 # termion cargo run --example demo --no-default-features --features=termion --release -- --tick-rate 200
tick-rate is the UI refresh rate in ms.
The UI code is in examples/demo/ui.rs while the application state is in examples/demo/app.rs.
If the user interface contains glyphs that are not displayed correctly by your terminal, you may want to run the demo without those symbols:
cargo run --example demo --release -- --tick-rate 200 --enhanced-graphics false
The library comes with the following list of widgets:
Click on each item to see the source of the example. Run the examples with with
cargo (e.g. to run the gauge example
cargo run --example gauge), and quit by pressing
You can run all examples by running
cargo make run-examples (require
cargo-make that can be installed with
cargo install cargo-make).
Apps using tui
- tokio-console: a diagnostics and debugging tool for asynchronous Rust programs.
- hwatch: a alternative watch command that records the result of command execution and can display its history and diffs.
- ytui-music: listen to music from youtube inside your terminal.
- mqttui: subscribe or publish to a MQTT Topic quickly from the terminal.
- meteo-tui: french weather via the command line.
- picterm: preview images in your terminal.
- gobang: a cross-platform TUI database management tool.
