A simple Terminal User Interface (TUI) library for .NET 9.0 that provides a scrollable text window using standard VT codes and the alternate terminal buffer.

• Display text content in a scrollable window
• Use arrow keys, page keys, home/end for navigation
• Automatic word-wrapping to fit terminal dimensions
• Visual scrollbar indicator
• Clean terminal handling using the alternate buffer
• Simple, fluent API

• .NET 9.0
• A terminal emulator that supports VT codes (most modern terminals)

Currently, you can include this library in your project directly:

dotnet add reference path/to/SimpleTUI.csproj

using SimpleTUI;

// Create a scrollable window with content
string content = "Your multi-line content to display...";
var window = TUI.CreateWindow(content);

// Optionally specify custom dimensions (width, height)
window.WithDimensions(80, 24);

// Display the window (blocks until user presses 'Q' to exit)
window.Show();

• ↑/↓ Arrow Keys: Scroll one line up or down
• Page Up/Down: Scroll one page up or down
• Home/End: Jump to beginning or end
• Q: Quit and return to normal console

The repository includes a demo project that showcases how to use the SimpleTUI library. Run the demo with:

cd Demo
dotnet run
