README

This is a small PHP (Symfony) application that find you reviewers to a Github pull request.

It is using a naive algorithm which:

1. First looks at the modified files in the PR
2. Do a git blame on each file to see who as modified the file
3. Sort the list of contributor, first contributor is the person that have changed the most files that the pull request touches

$ ./git-reviewer.php find 106 /path/to/local/repository --pretty-print

[
    {
        "email": "tobias.nyholm@gmail.com",
        "name": "Tobias Nyholm",
        "contributions": 3,
        "username": "Nyholm"
    },
    {
        "email": "ion.bazan@gmail.com",
        "name": "Ion Bazan",
        "contributions": 1,
        "username": "IonBazan"
    }
]

Calls to Github API

Github allows some anonymous calls, but it is a good idea to specify an environment variable named GITHUB_TOKEN. That should contain a Github token with "api" permissions.

You can create such token in your Github account under "Developer settings > Personal access tokens".
