yaml-parser

A small YAML parser, and a command line tool around it, written in Odin.

I started it because I wanted to learn a language I knew nothing about, with nothing to lean on, so I would have to understand every layer myself: bytes to tokens, tokens to a tree, tree back to text. That was the point, more than the parser.

It is not meant to be a serious tool. It covers the subset of YAML I happen to need, it is not trying to be complete, and I am not optimising it. I come back to it when I have time, usually to add one small thing, and I expect that to carry on for a while.

What it handles

Block mappings and sequences, comments, document markers, and plain, single quoted and double quoted scalars, with integers, floats, booleans and null typed on the way in.

Command line

yaml-parser get config.yaml services.api.port
yaml-parser set config.yaml services.api.port 8080

Key paths are dotted, and the exit code tells a script whether it found something.
