Terminal.Gui 2.0.0-develop.4715

Terminal.Gui v2

Cross-platform UI toolkit for building sophisticated terminal UI (TUI) applications on Windows, macOS, and Linux/Unix.

• v2 Alpha (Current): - Recommended for new projects
• v1 (Legacy): - Maintenance mode only

Important:

• v1 is in maintenance mode - only critical bug fixes accepted
• v2 Alpha is recommended for new projects - API is stable with comprehensive features
• Breaking changes possible before Beta, but core architecture is solid

Quick Start

Install the Terminal.Gui.Templates, create a new TUI app, and run it:

dotnet new --install Terminal.Gui.templates
dotnet new tui -n myproj
cd myproj
dotnet run

Press Esc to exit (the default QuitKey).

Run the comprehensive UI Catalog demo to explore all controls:

dotnet run --project Examples/UICatalog/UICatalog.csproj

Simple Example

using Terminal.Gui;

using IApplication app = Application.Create ();
app.Init ();

using Window window = new () { Title = "Hello World (Esc to quit)" };
Label label = new ()
{
    Text = "Hello, Terminal.Gui v2!",
    X = Pos.Center (),
    Y = Pos.Center ()
};
window.Add (label);

app.Run (window);
