This post is part of my Today I learned series in which I share all my web development learnings.

I use YAML sparingly, but occasionally I have to fiddle with GitHub actions that use it as their configuration format. After defining some CI/CD commands, I started looking into multi-line strings, and oh boy...

Multiline strings are annoying in any configuration format, but YAML reaches another level. There are nine (!) different ways to handle strings: , ', ", |, |+, |-, >, >+ and >-. Nine! 🤯

Check the YAML Playground or this StackOverflow answer. Big kudos to the person taking the time to write a novel describing string handling. 🙇‍♂️
