Dang it…is there a human-readable data format that is basically YAML syntax but the simple featureset of JSON (plus comments)?
I want something concise and Markdown-ish, made for human editing, like YAML, but without all of YAML’s…er, specialness.
EDIT: To be clear, this is for •primary content•, not configuration. It should •feel• like working with Markdown; it’s just that the output needs to be array-and-dict-shaped instead of HTML-shaped. (Lots of good suggestions in the replies already! TOML and KDL and are clear crowd favorites.)
