So, to source within Gitea you simply need to create an x-ray string, like the one below.
If you run the strings above in google you will get the results below.
Use your social detective skills and you are set. Also find a commit, open it and then put .patch at the end and their email will appear.
If you need more info on X-raying see my blog post http://www.recruitingblogs.com/profiles/blogs/seeing-what-is-really...
Until next week may the source be with you!!
