It's a well-known fact (or at least it should be) that everything you push to a public GitHub repository is public. This includes a lot of information other than just source files. Since both Git and GitHub require you to provide an email address, it should be no surprise that this information is public as well. FindGitHubEmail (catchy title, I know) is a simple script that queries the GitHub API and guesses a given user's email address based on their public activity. The script is a bit of a hack; sorry if your eyes are bleeding.
FindGitHubEmail makes it easy to get in contact with open source developers. Please use it for good, not evil.
Run this:
git clone https://github.com/hodgesmr/FindGitHubEmail.git ~/FindGitHubEmail
bash ~/FindGitHubEmail/findGitHubEmail hodgesmrIf you're not looking for me, replace hodgesmr with another GitHub user.
The above will return the most common email address found in a given user's event log. You can also see all possibilities:
git clone https://github.com/hodgesmr/FindGitHubEmail.git ~/FindGitHubEmail
bash ~/FindGitHubEmail/findGitHubEmail -a hodgesmrThis project is maintained by @hodgesmr.
