Where do I get grammars :P #435
Comments
Sorry, I don't know anything off the top of my head, but I leave this issue open for a while so folks can chime in. |
Well, I found a couple, and all of them were about a different implementation. That list is huge and out of date since 2015: https://slebok.github.io/zoo/index.html |
In labelled BNF (BNFC), each rule needs a distinct label. It does not cover all of EBNF, which also has * for lists etc. (and ? and +). |
Aha. So I wont be able to convert EBNF files properly. But partly? Your website doesnt make this clear. Lots of BNF files are out there, and you dont seem to know about a lot of grammars for LBNF. Does it seem to make sense, that full compatibility could raise the usefulness of this tool since we could produce a lot of grammars? In terms of backends and overall maintenance seems this project to be one of the leading figures. 😄 |
BNFC's concept is to be a common front-end to YACC-like parser generators in different languages. So we are just serving the common feature set.
There are feature requests, though, that ask for an extension of the LBNF formalism, e.g. for |
Ok? I didnt know you are supporting Yacc either? I am looking for a Yacc translator. Can you help me to translate the FSharp grammar? https://github.com/dotnet/fsharp/blob/main/src/Compiler/pars.fsy |
FSharp uses layout, so this does not fit into pure BNF or LBNF: https://fsharpforfunandprofit.com/posts/fsharp-syntax/ |
Hi there 👍🏻
I look for a FSharp ANTLR implementation.
Your project seems to be promising, considering that it outouts ANTLR, and I also read that you have an OCaml backend.
I probably miss something, because I know about a treesitter and an ANTLR grammar repository. And there seems to be no such thing for LBNF, BNF, ABNF or EBNF.
I understand that you only parse from LBNF, but J haven't found a grammar collection of existing languages at all.
Do you know, where I can get a F# xBNF grammar, or alternatively one from OCaml?
Thanks a lot ☀️
