Possible to generate EBNF from a parser?

[jessegrosjean]

I have a parser, now I'm wondering if I can generate EBNF from this parser.

I realize that the generation will be imperfect because of possibly of custom code, but it seems like the information is there to generate most of the high level structure, I'm just not sure how to extract it in a systematic way.

Anyone have thoughts or pointers on how I might do this?

Gonna convert this to a discussion since it's not an issue with the library.

My goal: How to I quickly generate documentation for the mini language I am parsing with swift-parsing so that a LLM can console and then help users to write this language.
