A Git post-commit hook that keeps your GitHub (or other) commit graph intact.

Saves all commits to non-owned repositories to your own repository as dummy commit (commit without changes), so you don't lose the commits when removed from the project or organization.

Dummy commit messages have the following format:

Original commit subject
https://url-to-non-owned-repository

1. Create a new remote repository (e.g. git-history) that will be used as dummy commit target
2. Clone the repository to your local machine and note its path
3. Download post-commit and set OWNED_REMOTE_URL_PREFIX and DUMMY_COMMIT_REPOSITORY_PATH
4. Make post-commit executable by running chmod +x post-commit
5. Copy post-commit to a project's .git/hooks directory to have it save dummy commits

1. Create a local commit for a project with post-commit installed
2. Check that your dummy commit repository (e.g. git-history) received the dummy commit
