Modern, cross-platform, terminal UIs since 2007
README.md

Modern, cross-platform, terminal UIs using .NET and Swift since 2007.

The tui-cs organization hosts projects related to gui.cs that Miguel de Icaza wrote for mono-curses in 2007. The org is now maintained by Tig Kindel.

The original gui.cs was a single file and tied to the curses library. Since then, gui.cs has been transformed into Terminal.Gui, a full-featured library for building modern, cross-platform, TUI applications.

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

Terminal.Gui

The other projects in this organization are either dependencies of Terminal.Gui or related offshoots.

Projects

  • Terminal.Gui — the cross-platform TUI toolkit for .NET (v2).
  • clet — CLI-lets: rich TUI prompts with consistent JSON output and clean exit codes, for humans and AI agents.
  • cli — a library that exposes Terminal.Gui views as scriptable CLI commands with typed JSON output, POSIX exit codes, and AI-agent discoverability.
  • PSTui — PowerShell TUI cmdlets (Out-ConsoleGridView/ocgv, Show-ObjectTree/shot), built on Terminal.Gui v2. The community continuation of Microsoft.PowerShell.ConsoleGuiTools — Install-Module PSTui.

The maintainers welcome contributions from the community.
