  It seems that Ruby uses GNU Bison: http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/trunk/parse.y?view=markup http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/trunk/parse.y?vi... It is not so clear for documentation purposes, but grammar rules are in between 850-4988 lines. File/Line size does not tell much about Grammar complexity, but anyway, the whole parse.y file is bigger than cpython/Parser directory. BTW, Ruby's parse.y file is just the input to Bison.

  One of my favorite things about Python 3 is that the grammar actually got smaller: http://docs.python.org/3/reference/grammar.html http://docs.python.org/3/reference/grammar.html It's only three lines, but still.
