EBNF Grammar for C

EBNF Grammar for C. GitHub Gist: instantly share code, notes, and snippets.

This is EBNF grammar for ANSI C (C99) and it contains almost every rule. It may be missing stuff, please tell me if you notice something missing.

I am writing a C compiler, with my backend and hopefully my own frontend in OCaml. That is why I wrote this grammar. I also have written the AWK grammar, but it’s not uploaded anywhere. Tell me if you want it.

Thanks.

    Trigraphs are handled by the preprocessor, so if you’re not handling that, then that’s fine. Digraphs are handled by the tokenizer, however.
