Hi Bulat, will the c-language package do ? Its parser seems to be based on Happy? http://hackage.haskell.org/package/language-c-0.8.1/docs/Language-C-Parser.h... http://hackage.haskell.org/package/language-c-0.8.1/docs/Language-C-Parser.h... Regards, Andrew

Hello all,

I develop a preprocessor transpiling subset of C statements into gcc _asm statements. For this project, I will be happy to reuse existing C statements parser written with any popular Haskell technology, or just start with some simple C subset parser in order to avoid redoing existing work.

Unfortunately, so far I found grammars just for everything but C. And while I can start with Parsec grammars for Java/Go, it seems that MegaParsec now is better choice?

I can quickly develop grammar for small C subset, but ready-to-use grammar for larger C subset will allow me to completely skip the development of C statement parser and focus on the meat of project - asm code generation.

Eventually, it may turn into LLVM pass transpiling parts of C++ code, but for quick prototype, I prefer Haskell, especially if I can find ready-to-use parser.

PS: It was the first time I ever asked at SO, but it turned out to be offtopic there: https://stackoverflow.com/questions/50949118/simple-c-grammar-for-haskell-pa...
