Terminal.Gui/Terminal.Gui

Terminal.Gui Project

All files required to build the Terminal.Gui library (and NuGet package).

Project Folder Structure

• Terminal.Gui.sln - The Visual Studio solution
• Core/ - Source files for all types that comprise the core building blocks of Terminal-Gui
  • Application - A static class that provides the base 'application driver'. Given it defines a Terminal.Gui application it is both logically and literally (because static) a singleton. It has direct dependencies on MainLoop, Events.cs NetDriver, CursesDriver, WindowsDriver, Responder, View, and TopLevel (and nothing else).
  • MainLoop - Defines IMainLoopDriver and implements the MainLoop class.
  • ConsoleDriver - Definition for the Console Driver API.
  • Events.cs - Defines keyboard and mouse-related structs & classes.
  • PosDim.cs - Implements Computed Layout system. These classes have deep dependencies on View.
  • Responder - Base class for the windowing class hierarchy. Implements support for keyboard & mouse input.
  • View - Derived from Responder, the base class for non-modal visual elements such as controls.
  • Toplevel - Derived from View, the base class for modal visual elements such as top-level windows and dialogs. Supports the concept of MenuBar and StatusBar.
  • Window - Derived from TopLevel; implements toplevel views with a visible frame and Title.
• Types/ - A folder (not namespace) containing implementations of Point, Rect, and Size which are ancient versions of the modern System.Drawing.Point, System.Drawing.Size, and System.Drawning.Rectangle.
• ConsoleDrivers/ - Source files for the three ConsoleDriver-based drivers: .NET: NetDriver, Unix & Mac: UnixDriver, and Windows: WindowsDriver.
• Views/ - A folder (not namespace) containing the source for all built-in classes that derive from View (non-modals).
• Windows/ - A folder (not namespace) containing the source of all built-in classes that derive from Window.

Version numbers

Version info for Terminal.Gui is managed by gitversion.

Install gitversion:

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

The project version (the nuget package and in Terminal.Gui.dll) is determined from the latest git tag.

The format of version numbers is vmajor.minor.patch.build and follows the Semantic Versioning rules.

To define a new version (e.g. with a higher major, minor, patch, or build value) tag a commit using git tag:

git tag v1.2.3 -a -m "Release v1.2.3"
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.

Automatic Nuget Publishing

The following actions will publish the Terminal.Gui package to Nuget:

• A new version tag is defined and pushed to v1_release - this is the normal release process.
• A push to the v1_release branch without a new version tag - this is a release-candidate build and will be of the form 1.2.3-rc.4
• A push to the v1_develop branch - this is a pre-release build and will be of the form 1.2.3-pre.4

Publishing a Release of Terminal.Gui

First, use the Semantic Versioning rules to determine the new version number.

Given a version number MAJOR.MINOR.PATCH, increment the:

• MAJOR version when you make incompatible API changes
• MINOR version when you add functionality in a backward-compatible manner
• PATCH version when you make backwards-compatible bug fixes

To release a new version (e.g. with a higher major, minor, or patch value) tag a commit using git tag and then push that tag directly to the main branch on github.com/gui-cs/Terminal.Gui (upstream).

The tag must be of the form v<major>.<minor>.<patch>, e.g. v1.2.3.

1) Verify the develop branch is ready for release

• Ensure everything is committed and pushed to the v1_develop branch
• Ensure your local v1_develop branch is up-to-date with upstream/v1_develop

2) Create a pull request for the release in the v1_develop branch

The PR title should be of the form "Release v1.2.3"

git checkout v1_develop
git pull upstream v1_develop
git checkout -b v1_2_3
<touch a file>
git add .
git commit -m "Release v1.2.3"
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 to v1_develop

• Merging the PR will trigger the publish action on upstream (the main repo) and publish the Nuget package as a pre-release (e.g. 1.2.3-pre.1).

4) Pull the merged develop from upstream

git checkout v1_develop
git pull upstream v1_develop

5) Merge develop into main

git checkout v1_release
git pull upstream v1_release
git merge v1_develop

Fix any merge errors.

At this point, to release a release candidate, push the v1_release branch upstream without a new tag.

git push upstream v1_release

This will publish 1.2.3-rc.1 to Nuget.

6) Create a new annotated tag for the release on v1_release

git tag v1.2.3 -a -m "Release v1.2.3"

7) Push the new tag to main on upstream

git push --atomic upstream main v1.2.3

See https://stackoverflow.com/a/3745250/297526

This will publish 1.2.3 to Nuget.

8) Monitor Github Actions to ensure the Nuget publishing worked.

https://github.com/gui-cs/Terminal.Gui/actions

9) Check Nuget to see the new package version (wait a few minutes)

https://www.nuget.org/packages/Terminal.Gui

10) Add a new Release in Github: https://github.com/gui-cs/Terminal.Gui/releases

Generate release notes with the list of PRs since the last release.

11) Update the v1_develop branch with the new version

git checkout v1_develop
git pull upstream v1_develop
git merge v1_release
git push upstream v1_develop
