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