Description

In Unity 2018.3, the Unity Package Manager (UPM) supported Git. :)
https://forum.unity.com/threads/git-support-on-package-manager.573673/

This update allows us to quickly install packages on code hosting services such as GitHub.
But, I'm not quite satisfied with the feature. :(

• Incorrect links to documents (readme, changelog, license)
• There is not a link to repo URL
• I wanna add, update, and remove the packages in the UI

This project extends the UI of Unity Package Manager for package installed using git!

Features

• Show link to repository URL
• Override link to the document URL
  • Readme
  • Changelog
  • License
• Support GitHub, Bitbucket and GitLab
• Add package from url
• Remove package
• Update package with a specific tag/branch
• Support Unity 2019.1+
• Support .Net 3.5 & 4.x

Future plans

• View offline documents for private repository
• Display license
• Override the document URL with package.json

Install

Find Packages/manifest.json in your project and edit it to look like this:

{
  "dependencies": {

    ...
  },
}

Development Note

Develop a package for UPM

The branching strategy when I develop a package for UPM is as follows.

Branch	Description	'Assets' directory
develop	Development, Testing	Included
master	Publishing	Included
upm(default)	Subtree to publish for UPM	Excluded
{tags}	Tags to install using UPM	Excluded

Steps to release a package:

1. Update version in package.json.
2. Develop package project on develop branch.
3. Close all issues on GitHub for new version.
4. Generate CHANGELOG.md using github_changelog_generator and commit it.
5. Merge into master branch and publish as new version.
6. Split subtree into ump branch.
7. Tag on ump branch as new version.
8. Release.

About default document URL

The document URL in UnityPackageManager 2.0.3 is hard-coded.
The default values are as follows:

• View document: http://docs.unity3d.com/Packages/{ShortVersionId}/index.html or official manual page (only for built in package)
• View changelog: http://docs.unity3d.com/Packages/{ShortVersionId}/changelog/CHANGELOG.html
• View licenses: http://docs.unity3d.com/Packages/{ShortVersionId}/license/index.html or https://unity3d.com/legal/licenses/Unity_Companion_License

ShortVersionId is defined as follows:

• {PackageName}@{MajorVersion}.{MinorVersion}
• For example: com.coffee.upm-git-extension@0.1

How to add/update/remove a package from script?

Use UnityEditor.PackageManager.Client class.
https://docs.unity3d.com/ScriptReference/PackageManager.Client.html

• Add/Update: Client.Add({PackageId})
• Remove: Client.Remove({PackageName})

PackageId is defined as follows:

• {PackageName}@{MajorVersion}.{MinorVersion}.{PatchVersion} (Unity official package)
• {PackageName}@{RepoURL}#{BranchOrTagOrRevision}
• For example: com.unity.package-manager-ui@2.0.3, coffee.upm-git-extension@https://github.com/mob-sakai/UpmGitExtension.git#1.1.1
