With all this discussion about P/D yacc, what about stacc from
Georgia Tech? I admit it is in ratfor, but would it work or
could it be recoded to C for those interested? (could it be
recoded and posted?) Maybe it is not truly P/D, but it can be
had farily cheapy as I recall.

The new release of Kermit for 4.2bsd contains a yacc-like program
stated to be in the public domain (by the Kermit documentation) called
"wart." It's apparently a subset.

Before people start clamouring for this to be posted, I should say that
the "wart" program in the latest C-Kermit distribution is really a PD
lex subset and not a PD yacc as stated in <1013@utastro.UUCP>.

It's apparently a subset. Excuse me, but "wart" is a subset of lex, not yacc. robert -- Robert Viduya Georgia Institute of Technology ...!{akgua,allegra,amd,hplabs,ihnp4,masscomp,ut-ngp}!gatech!gitpyr!robert ...!{rlgvax,sb1,uf-cgrl,unmvax,ut-sally}!gatech!gitpyr!robert

For those who don't know, stacc is STill Another Compiler Compiler, which is similar to Yacc, but produces a recursive descent parser (in any of Ratfor, C, Pascal, PL/1, or Plp). It is written in itself, using ratfor. I should mention that Prime Fortran allows recursive subroutines and functions or else it wouldn't work. The ratfor used at Georgia Tech on primes is NOT compatible with Unix Ratfor, either... One of our very far back on the burner projects is to rewrite stacc in C, and possibly post it (depending on if the lawyers would let us). There are one or two other programs that have been rewritten in C from the Georgia Tech Software Tools Subsystem, including the 'se' screen editor. I hope to post these, eventually, if and only iff the lawyers will let me. -- Arnold Robbins CSNET: arnold@gatech ARPA: arnold%gatech.csnet@csnet-relay.arpa UUCP: { akgua, allegra, hplabs, ihnp4, seismo, ut-sally }!gatech!arnold Help advance the state of Computer Science: Nuke a PR1ME today!
