YAML Parser/Emitter Library for Koka

[syaiful6]

I played with this project lately, and need a YAML parser functionality. So, I created one here: https://github.com/syaiful6/yaml.kk It also can be used as reference how to call FFI, especially C. I also learned a lot. But, to my surprise it far more easier than writing OCaml FFI. 👍

It still not completed, currently it will yield libyaml event for the given file. I am still tinkering how the API will look like. It will be nice, if we can serialize/deserialize it into our struct/data type.
