Terminal.Gui Project

Terminal.Gui is a cross-platform UI toolkit for creating console-based graphical user interfaces in .NET. This repository contains all files required to build the Terminal.Gui library and NuGet package, enabling developers to create rich terminal applications with ease.

Project Overview

Terminal.Gui provides a comprehensive framework for building interactive console applications with support for keyboard and mouse input, customizable views, and a robust event system. It is designed to work across Windows, macOS, and Linux, leveraging platform-specific console capabilities where available.

Project Folder Structure

• \ - The root folder contains the core solution and project files for the library.

  • Terminal.Gui.sln - The Visual Studio solution file for the project.
  • Terminal.Gui.csproj - The project file defining build configurations and dependencies.
  • App\ - Contains the core Application logic, including Application.cs, a static class that serves as the base 'application engine', managing RunState and MainLoop.

• Configuration\ - Classes related to the ConfigurationManager for handling application settings.

• Drivers\ - Contains the console driver implementations:

  • IConsoleDriver.cs - Defines the Console Driver API.
  • Driver implementations for .NET (DotNetDriver), Unix & macOS (UnixDriver), and Windows (WindowsDriver).

• Drawing\ - Classes related to rendering graphical elements in the console.

• FileServices\ - Utility classes for file operations and services.

• Input\ - Classes handling keyboard and mouse input:

  • Events.cs - Defines structs and classes for keyboard and mouse events.

• Resources\ - Assets and resources used by the library.

• Text\ - Classes for text processing and formatting.

• View\ - Core View class hierarchy (excluding specific sub-classes):

  • View.cs - The base class for non-modal visual elements such as controls.
  • Related subdirectories for layout and positioning logic.

• ViewBase\ - Base classes and utilities for views.

• Views\ - Specific sub-classes of View:

  • Toplevel - Base class for modal visual elements like top-level windows and dialogs, supporting MenuBar and StatusBar.
  • Window - Implements framed top-level views with titles.
  • Dialog - Specialized windows for user interaction.
  • Other specialized view classes.

Getting Started

For instructions on how to start using Terminal.Gui, refer to the Getting Started Guide in our documentation.

Documentation

Comprehensive documentation for Terminal.Gui is available at gui-cs.github.io/Terminal.Gui. Key resources include:

• Events Deep Dive - Detailed guide on event handling and the Cancellable Work Pattern.
• View Documentation - Information on creating and customizing views.
• Keyboard Handling - Guide to managing keyboard input.
• Mouse Support - Details on implementing mouse interactions.
• Showcase - A collection of applications and examples built with Terminal.Gui.

For information on generating and updating the API documentation locally, refer to the DocFX README in the docfx folder.

Versioning

Version information for Terminal.Gui is managed by gitversion. To install gitversion:

dotnet tool install --global GitVersion.Tool
dotnet-gitversion

The project version (used in the NuGet package and Terminal.Gui.dll) is determined from the latest git tag. The format of version numbers is major.minor.patch.build.height and follows Semantic Versioning rules.

To define a new version, tag a commit using git tag:

git tag v1.3.4-beta.5 -a -m "Release v1.3.4 Beta 5"
dotnet-gitversion /updateprojectfiles
dotnet build -c Release

DO NOT COMMIT AFTER USING /updateprojectfiles! Doing so will update the .csproj files in your branch with version info, which we do not want.

Publishing a Release of Terminal.Gui

To release a new version, follow these steps based on Semantic Versioning rules:

• MAJOR version for incompatible API changes.
• MINOR version for backwards-compatible functionality additions.
• PATCH version for backwards-compatible bug fixes.

Steps for Release:

1. Verify the develop branch is ready for release:

   • Ensure all changes are committed and pushed to the develop branch.
   • Ensure your local develop branch is up-to-date with upstream/develop.

2. Create a pull request for the release in the develop branch:

   • Title the PR as "Release vX.Y.Z".

     git checkout develop
     git pull upstream develop
     git checkout -b vX_Y_Z
     git add .
     git commit -m "Release vX.Y.Z"
     git push
     

   • Go to the link printed by git push and fill out the Pull Request.

3. On github.com, verify the build action worked on your fork, then merge the PR.

4. Pull the merged develop from upstream:

   git checkout develop
   git pull upstream develop
   

5. Merge develop into main:

   git checkout main
   git pull upstream main
   git merge develop
   

   • Fix any merge errors.

6. Create a new annotated tag for the release on main:

   git tag vX.Y.Z -a -m "Release vX.Y.Z"
   

7. Push the new tag to main on upstream:

   git push --atomic upstream main vX.Y.Z
   

8. Monitor Github Actions to ensure the NuGet publishing worked:

   • Check GitHub Actions.

9. Check NuGet to see the new package version (wait a few minutes):

   • Visit NuGet Package.

10. Add a new Release in Github:

    • Go to GitHub Releases and generate release notes with the list of PRs since the last release.

11. Update the develop branch with the new version:

    git checkout develop
    git pull upstream develop
    git merge main
    git push upstream develop
    

NuGet

The official NuGet package for Terminal.Gui is available at https://www.nuget.org/packages/Terminal.Gui. When a new version tag is defined and merged into main, a NuGet package is automatically generated by a GitHub Action. Pre-release versions (e.g., 1.3.4-beta.5) are tagged as pre-release on NuGet.
