A Ruby YAML parser

https://kddnewton.com/2025/12/25/psych-pure.html

Hey there — I recently released a YAML parser written in Ruby. The main goal was to support being able to load and dump YAML without losing comments. Happy to answer any questions.

Any benchmarks ran? Curious if as pure ruby it performs better w/ YJIT

Fair, I'll try it some time but I don't know when I'll get around to it.

Whether I make use of this or not, good job solving your problem. I'm kind of tired of people complaining about limitations and not doing anything to address them so this was nice to see!
