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.
Are digraphs and trigraphs deprecated?
Did you reference the standard?
I think digraphs and trigraphs are part of the preprocessor? I did not add any preprocessor stuff to this grammar. I am adding them to the new version I am working on.
I have read the C17 standard fully and I did recall it from memory from time to time but it seems like I had forgotten a lot of stuff. I am redefining it, and I am redigning my AWK grammar too.
I am hoping I could perhaps make a Github pages website called Internet Grammar Database and have all sorts of grammar inside it. Thoughts?
I love grammars. It’s like an API or a data schema, but for a language. This would be very cool and I would love to see it!
Cool! I will make it.
Trigraphs are handled by the preprocessor, so if you’re not handling that, then that’s fine. Digraphs are handled by the tokenizer, however.
Cool, I am making a second version were things are cleaner, I will add digraphs, trigraphs and preprocessor directives to the gramamr as wel. Thanks.
