I also needed a LR parser for my project, so I checked a few ones written
in lisp, but found none that where as nice as UNIX's YACC. As a partial
solution,
I wrote some lisp code that enables you to write your YACC grammer in lisp,
generate the YACC format file read back the YACC generated parser into lisp
and
construct the automata from the YACC parser.

This setup, while clumsyer than having YACC in lisp, works very well if you
have
an AppleShare server on the UNIX side (such as CAP), enabling you to write
and read
files directly from MCL onto the UNIX side.

If you want, I can send you the code, but I wont have any time to comment
it
or remove all the personal stuff that may be imbeded in it.
