Terminal.Gui - Cross Platform Terminal UI toolkit for .NET

A toolkit for building rich console apps for .NET, .NET Core, and Mono that works on Windows, the Mac, and Linux/Unix.

Sample app

Controls and Views

Terminal.Gui provides a rich set of views and controls for building terminal user interfaces:

Features

Cross Platform - Windows, Mac, and Linux. Terminal drivers for Curses, Windows Console, and the .NET Console mean apps will work well on both color and monochrome terminals.
Keyboard and Mouse Input - Both keyboard and mouse input are supported, including support for drag & drop.
Flexible Layout - Supports both Absolute layout and an innovative Computed Layout system. Computed Layout makes it easy to layout controls relative to each other and enables dynamic terminal UIs.
Clipboard support - Cut, Copy, and Paste of text provided through the Clipboard class.
Arbitrary Views - All visible UI elements are subclasses of the View class, and these in turn can contain an arbitrary number of sub-views.
Advanced App Features - The Mainloop supports processing events, idle handlers, timers, and monitoring file descriptors. Most classes are safe for threading.
Reactive Extensions - Use reactive extensions and benefit from increased code readability, and the ability to apply the MVVM pattern and ReactiveUI data bindings. See the source code of a sample app in order to learn how to achieve this.

Keyboard Input Handling

Terminal.Gui respects common Linux, Mac, and Windows keyboard idioms. For example, clipboard operations use the familiar Control/Command-C, X, V model. CTRL-Q is used for exiting views (and apps).

The input handling of Terminal.Gui is similar in some ways to Emacs and the Midnight Commander, so you can expect some of the special key combinations to be active.

The key ESC can act as an Alt modifier (or Meta in Emacs parlance), to allow input on terminals that do not have an alt key. So to produce the sequence Alt-F, you can press either Alt-F, or ESC followed by the key F.

To enter the key ESC, you can either press ESC and wait 100 milliseconds, or you can press ESC twice.

ESC-0, and ESC-1 through ESC-9 have a special meaning, they map to F10, and F1 to F9 respectively.

Apps can change key bindings using the AddKeyBinding API.

Driver Model

Terminal.Gui has support for ncurses, System.Console, and a full Win32 Console front-end.

ncurses is used on Mac/Linux/Unix with color support based on what your library is compiled with; the Windows driver supports full color and mouse, and an easy-to-debug System.Console can be used on Windows and Unix, but lacks mouse support.

You can force the use of System.Console on Unix as well; see Core.cs.

Showcase & Examples

UI Catalog - The UI Catalog project provides an easy to use and extend sample illustrating the capabilities of Terminal.Gui. Run dotnet run --project UICatalog to run the UI Catalog.
Reactive Example - A sample app that shows how to use System.Reactive and ReactiveUI with Terminal.Gui. The app uses the MVVM architecture that may seem familiar to folks coming from WPF, Xamarin Forms, UWP, Avalonia, or Windows Forms. In this app, we implement the data bindings using ReactiveUI WhenAnyValue syntax and Pharmacist — a tool that converts all events in a NuGet package into observable wrappers.
Example (aka demo.cs) - Run dotnet run in the Example directory to run the simple demo.
Standalone Example - A trivial .NET core sample application can be found in the StandaloneExample directory. Run dotnet run in directory to test.
F# Example - An example showing how to build a Terminal.Gui app using F#.
PowerShell's Out-ConsoleGridView - OCGV sends the output from a command to an interactive table.
PoshRedisViewer - A compact Redis viewer module for PowerShell written in F# and Gui.cs

Documentation

See the Terminal.Gui/ README for an overview of how the library is structured. The Conceptual Documentation provides insight into core concepts.

Sample Usage

(This code uses C# 9.0 Top-level statements.)

using Terminal.Gui;
using NStack;

Application.Init();
var top = Application.Top;

// Creates the top-level window to show
var win = new Window("MyApp")
{
	X = 0,
	Y = 1, // Leave one row for the toplevel menu

	// By using Dim.Fill(), it will automatically resize without manual intervention
	Width = Dim.Fill(),
	Height = Dim.Fill()
};

top.Add(win);

// Creates a menubar, the item "New" has a help menu.
var menu = new MenuBar(new MenuBarItem[] {
			new MenuBarItem ("_File", new MenuItem [] {
				new MenuItem ("_New", "Creates new file", null),
				new MenuItem ("_Close", "",null),
				new MenuItem ("_Quit", "", () => { if (Quit ()) top.Running = false; })
			}),
			new MenuBarItem ("_Edit", new MenuItem [] {
				new MenuItem ("_Copy", "", null),
				new MenuItem ("C_ut", "", null),
				new MenuItem ("_Paste", "", null)
			})
		});
top.Add(menu);

static bool Quit()
{
	var n = MessageBox.Query(50, 7, "Quit Demo", "Are you sure you want to quit this demo?", "Yes", "No");
	return n == 0;
}

var login = new Label("Login: ") { X = 3, Y = 2 };
var password = new Label("Password: ")
{
	X = Pos.Left(login),
	Y = Pos.Top(login) + 1
};
var loginText = new TextField("")
{
	X = Pos.Right(password),
	Y = Pos.Top(login),
	Width = 40
};
var passText = new TextField("")
{
	Secret = true,
	X = Pos.Left(loginText),
	Y = Pos.Top(password),
	Width = Dim.Width(loginText)
};

// Add some controls, 
win.Add(
	// The ones with my favorite layout system, Computed
	login, password, loginText, passText,

	// The ones laid out like an australopithecus, with Absolute positions:
	new CheckBox(3, 6, "Remember me"),
	new RadioGroup(3, 8, new ustring[] { "_Personal", "_Company" }, 0),
	new Button(3, 14, "Ok"),
	new Button(10, 14, "Cancel"),
	new Label(3, 18, "Press F9 or ESC plus 9 to activate the menubar")
);

Application.Run();
Application.Shutdown();

The example above shows adding views using both styles of layout supported by Terminal.Gui: Absolute layout and Computed layout.

Alternatively, you can encapsulate the app behavior in a new Window-derived class, say App.cs containing the code above, and simplify your Main method to:

using Terminal.Gui;

class Demo {
	static void Main ()
	{
		Application.Run<App> ();
		Application.Shutdown ();
	}
}

Installing

Use NuGet to install the Terminal.Gui NuGet package: https://www.nuget.org/packages/Terminal.Gui

Installation in .NET Core Projects

To install Terminal.Gui into a .NET Core project, use the dotnet CLI tool with following command.

dotnet add package Terminal.Gui

Running and Building

Windows, Mac, and Linux - Build and run using the .NET SDK command line tools (dotnet build in the root directory). Run UICatalog with dotnet run --project UICatalog.
Windows - Open Terminal.Gui.sln with Visual Studio 2019.

Building in Release requires the git command line tool (a dependency of the MinVer build tool)

History

This is an updated version of gui.cs that Miguel wrote for mono-curses in 2007.

The original gui.cs was a UI toolkit in a single file and tied to curses. This version tries to be console-agnostic and instead of having a container/widget model, only uses Views (which can contain subviews) and changes the rendering model to rely on damage regions instead of burdening each view with the details.

A presentation of this was part of the Retro.NET talk at .NET Conf 2018 Slides

Release history can be found in the Terminal.Gui.csproj file.

In 2019, 2020, and 2021, Charlie Kindel (https://github.com/tig), @BDisp (https://github.com/BDisp), and Thomas Nind (https://github.com/tznind) vastly extended, improved, polished and fixed gui.cs to what it is today.
