Tonttu ef20ff68a9 Reduce string allocations in IConsoleOutput implementations (#3978)
* Change IConsoleOutput.Write(string) overload parameter to ReadOnlySpan<char>

Allows the caller more flexibility about choosing a buffer per use case.

* NetOutput: Write StringBuilder directly to the std out text stream

* Add EscSeqUtils.CSI_WriteCursorPosition

Writes cursor position sequence to text writer without string allocation.

* NetOutput: Skip cursor position escape sequence string allocation

* Replace CSI_(Enable|Disable)MouseEvents static properties with readonly fields

Changed for the sake of consistency with rest of the EscSegutils fields rather than performance. Also prevents bugs from accidentally setting the properties.

* Use EscSeqUtils.CSI_Append(Foreground|Background)ColorRGB in v2 drivers

* WindowsOutput SetCursorVisibility: Remove intermediate string builder

* WindowsOutput.WriteToConsole: Use rented array as intermediate write buffer

The large intermediate string builder remains a challenge. :)

* NetOutput: Console.Out for the sake of consistency

Also might have missed one of the Console.Out.Write(StringBuilder) calls...

* Avoid Rune.ToString() in NetOutput.Write(IOutputBuffer)

Terminal.Gui .NET Core Version Code Coverage Downloads License Bugs

  • The current, stable, release of Terminal.Gui v1 is Version.
  • The current prealpha release of Terminal.Gui v2 can be found on Nuget.
  • Developers starting new TUI projects are encouraged to target v2. The API is significantly changed, and significantly improved. There will be breaking changes in the API before Beta, but the core API is stable.
  • v1 is in maintenance mode and we will only accept PRs for issues impacting existing functionality.

Terminal.Gui: A toolkit for building rich console apps for Windows, the Mac, and Linux/Unix.

Sample app

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

There is also a visual designer (uses Terminal.Gui itself).

Documentation

The above documentation matches the most recent Nuget release from the v2_develop branch. Get the v1 documentation here.

See the Terminal.Gui/README for an overview of how the library is structured.

Showcase & Examples

Terminal.Gui can be used with any .Net language to create feature rich and robust applications.
Showcase is a place where you can find all kind of projects from simple examples to advanced real world apps that fully utilize capabilities of the toolkit.
The team is looking forward to seeing new amazing projects made by the community to be added there!

Sample Usage in C#

The following example shows a basic Terminal.Gui application in C#:
Example (source)

When run the application looks as follows:
