parsing – What’s the best tool for generating a parser in Java for my own language grammar? – Education Career Blog

I’m developing a small programming language based mostly of the C99 standard and I’ve already written a fairly decent lexer in java and now I’m looking to generate a Java Parser from the grammar. I know there’s Bison, but that seems to only generate C code. I’m looking for a application that will allow me to input my grammar and create a full parser class in java code. Reading other SO posts on related topics, I’ve found ANTLR, but I’m wondering if anyone in the SO knows about a better tool?



Another couple to look at are JavaCC and SableCC (it has been a long time since I looked at SableCC).


I’ve been quite impressed by BNFC, which is able to generate parsers in Java as well as in C, C++, C#, F#, Haskell, and OCaml.


The JFlex home page at indicates where to find Bison-like tools that can target Java:
