[net.unix] Info wanted about EYACC

groot@ark.UUCP (Eddo de Groot) (01/22/85)

Does anybody know where to find a (on/off) line document describ-
ing  the  features of EYACC. We've heard a lot about it, all kind
of wild stories about beautifull error-recovery.  We've  got  the
program,  but no manual or other paper describing the differences
with the old YACC.

The only documentation I've seen on EYACC so far is in the source for the
UCB Berkeley Pascal compiler. A 'READ_ME' in the source for EYACC states
that a paper was to be presented at the '79 SIGPLAN meeting.

I don't think that they have any cut-and-dryed error recovery routines. I've
seen the error recovery in the 'pc' compiler, but I have yet to fully
understand how it performs the error recovery.

The paper on eyacc is

"Practical LR Error Recovery", by S.L. Graham, C.B. Haley, W.N. Joy,
SIGPLAN(14,8) August 1979, pp. 168-175.  ACM #0-89791-002-8/79/0800-0168
$00.75.

It helps a lot in understanding what is really going on in eyacc.  -Robert
