git-unrealmodule

Manage git repositories inside git repositories with Unreal Modules.

Background

• You deploy code using git to a system where all the code must be committed inside the repository
• You want to share code between your projects
• You cannot or do not want to use git submodules

Unreal Modules can help you in this situation.

Usage

Define a list of subrepositories and paths in a .unrealmodules file

path/in/the/repo|https://github.com/epeli/git-unrealmodule|master
something/else|https://github.com/epeli/redux-render-prop

• Commit .unrealmodules in to the parent repository.
• Clone the subrepositories using git unrealmodule clone
• Work on the parent and/or cloned subrepositories
• Commit the subrepositories to the parent repository with git unrealmodule commit

Now when new developers come to the project they do not have to know anything at all about the Unreal Modules. They can just clone the repository and continue as if Unreal Modules were never used. That's why they are called "Unreal".

But if they (or you with a fresh clone) want to commit code back to the subrepository upstreams they can restore the .git directories for the Unreal Modules with git unrealmodule restore.

If there has been changes to the subrepository from the parent repository the changes will appear as untracked changes in the subrepository.
