https://webglossary.info/ is based on a book (“The Web Development Glossary”). Though both book and website use Markdown, I had to write a script that converts everything so that the book can fuel the site. (This works, and automated book–site conversion is pretty cool!) Working on that script has been weird, some peers suggested to use Node instead, but I—kind of really liked writing it, and enjoyed working quite a bit with #sed! (Is it just me, or are shell scripts really fun?)
