This came up as I recommended using Observable as a core tool for documenting AgentScript, a “kit” for making agent based models. It was followed by “Oh boy, another thing to learn…

The parser for the notebook documents all the added syntax, although that may be too low level for your use cases.

This is a great idea for documentation. I started one in April (it’s called “Observable’s not JavaScript!” even). I put a bit more work into today and it should be available soon, time permitting. Thanks for the feedback!

To briefly dive into the absurdity of modern parsing toolchains :stuck_out_tongue_winking_eye:: for us and probably most projects that implement new languages or language features, you have a few different parsers with really different priorities. Our Acorn -based parser that we use to translate to J…
