GitHub Pages -> GitHub Repo bookmarklet

README.md

Toggle between GitHub Repo and GitHub Pages

If the current page is a GitHub Pages page, open the corresponding repo. if the current page is a repo, open the GitHub Pages page.

For example, if the current page is https://osteele.github.io/p5.layers, clicking the bookmarklet navigates https://github.com/osteele/p5.layers, and vice versa.

Limitations:

• Does not respect custom domains (CNAME)
• Does not work for organization repos

How to Use

1. Add a new bookmark. (For example, bookmark this page.)

2. Rename the bookmark. For example, GHP↔︎GH.
