まず、必要なファイルをホストする新しいリポジトリを作成します。 GitHubを使用している場合は、README.mdファイルで初期化して、自動的にmasterブランチ。


$ git remote add repository-name [email protected]:yourname/repository-name.git
$ git subtree add --prefix=subfolder/path/you/want repository-name master

Change repository-name, subfolder/path/you/want and yourname with your chosen names.

You can add --squash to the last command if the project want to incorporate has already many commits, and you want to pull all changes in one single commit.

You’re done!

Pushing and pulling

Now, suppose someone pushes a PR on that subrepository, or you edit it from another project.

To incorporate the changes inside your project, do:

git subtree pull --prefix=subfolder/path/you/want repository-name master

You can add --squash if you want to incorporate all changes in one single commit.

Now you’ll push to your own project, and the changes made in the subrepository are stored in the Git history of it.

To also push those changes to the subrepository Git history, and to the remote, just do

git subtree push --prefix=subfolder/path/you/want repository-name master

Again, use --squash if you feel it appropriate. Git will cherry-pick the commits that involve the subrepository subdirectory, so you’ll just see those changes in the subrepository history.

You might want to be careful and differentiate the commits that involve the subrepository. In this way you’ll keep things separated.
