Terminal.Gui v2 introduces a transformative redesign, simplifying the library's architecture and improving maintainability. Key changes include: - Added TrueColor support with 24-bit RGB handling. - Introduced `Adornment` framework for borders, padding, and margins. - Enhanced Unicode and wide character support for internationalization. - Added `LineCanvas` for drawing lines and shapes with box-drawing characters. - Simplified API by consolidating redundant methods and aligning with modern .NET standards. - Introduced `ConfigurationManager` for user-customizable themes and text styles. - Improved scrolling with `Viewport` and integrated `ScrollBar`. - Added new layout features like `Dim.Auto`, `Pos.AnchorEnd`, and `Pos.Align`. - Overhauled keyboard and mouse APIs for better input handling. - Introduced new views (e.g., `DatePicker`, `ColorPicker`, `GraphView`) and enhanced existing ones. - Added Sixel image support for rendering graphics in compatible terminals. - Ensured AOT compatibility for improved deployment and performance. This update lays the foundation for building modern, user-friendly terminal applications.
Terminal.Gui v2
The premier toolkit for building rich console apps for Windows, the Mac, and Linux/Unix.
⚠️ Note:
v1is in maintenance mode and we will only accept PRs for issues impacting existing functionality.
⚠️ Note:
Developers starting new TUI projects are encouraged to targetv2 Alpha. The API is significantly changed, and significantly improved. There will be breaking changes in the API before Beta, but the core API is stable.
Quick Start
Paste these commands into your favorite terminal on Windows, Mac, or Linux. This will install the Terminal.Gui.Templates, create a new "Hello World" TUI app, and run it.
(Press CTRL-Q to exit the app)
dotnet new --install Terminal.Gui.templates
dotnet new tui -n myproj
cd myproj
dotnet run
To run the UICatalog demo app that shows all the controls and features of the toolkit, use the following command:
dotnet run --project Examples/UICatalog/UICatalog.csproj
There is also a visual designer (uses Terminal.Gui itself).

The full developer documentation for Terminal.Gui is available at gui-cs.github.io/Terminal.Gui.
