Depends on what you mean by decent.  There are a number of parser/lexers out 
there that do a reasonable job.  If you mean the ruby equivalent of antlr, 
then you are, currently out of luck.

Rockit needs some work for 1.8.  Robert Feldt is the owner and I am not sure 
of what he is up to these days.  Looks like an update is planned, but I have 
no idea of the when or where.

There are some other options, though I am not sure they mean "decent":

  racc -- a YACC compiler-compiler
  
  Two versions of Coco/R (LL-1 parser-scanner), one from Ryan Davis in pure
  Ruby and the other from me as a C extension (grammer and action in C,
  produces a Ruby extension).  I am looking at updating my version to be
  an LL-k parser but that is a ways away yet.

This doesn't really help with the Rockit question though ..

Regards,
