Boto is a C# library to build rich terminal user interfaces and dashboards. It is heavily inspired by the Javascript library blessed-contrib, the Go library termui and the Rust library tui .

The library supports multiple backends:

• Tutu

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.

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.

The demo shown in the gif can be run with all available backends.

# tutu
dotnet run --project ./sample/Demo --release -- --tick-rate 200

where tick-rate is the UI refresh rate in ms.

The UI code is in samples/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:

The library comes with the following list of widgets:

• Block
• Gauge
• Sparkline
• Chart
• BarChart
• List
• Table
• Paragraph
• Canvas (with line, point cloud, map)
• Tabs

Click on each item to see the source of the example. Run the examples with with cargo (e.g. to run the gauge example dotnet run --project ./samples/GaugeSample), and quit by pressing q.
