byaccj vs cup vs javacc

[Jimmy zhang]

Hi, I was in the process of selecting a compiler compiler
for my project. So far there are three options for Java
CUP, byaccj and javacc, can someone comment on the
pros and cons of each options? I am interested in the
maturity, adoption and ease of use, among other aspects.
Cheers,
Jimmy

I needed to compare java parser generators and found JavaCUP to be most
suitable in my project which involved parsing C language. It scored good on
both parameters that you are looking for.
I could input the ANSI grammer with minor modifications using JavaCUP.

Unfortunately, I don't have a detailed comparison report now.

Naveen Sharma.

You forgot ANTLR.

I'll only comment on byacc/j, since that is what I use. It is Berkeley
YACC, but it generates Java instead of C. I don't know what else to say
other than it is YACC, the parser skeleton is well-written, and it
works. If you are already using and happy with some variant of YACC,
going with yacc/j is a no-brainer.

Support is rather spotty, although a new version was released last month
fixing a few issues. There really isn't much development going on with
any YACC, so byacc/j is no different in this regard.
