eyacc(1)
Name
eyacc − modified yacc allowing much improved error recovery
Syntax
eyacc [−v] [grammar]
Description
The eyacc command is an old version of yacc(,), which produces tables used by the Pascal system and its error recovery routines. The eyacc command fully enumerates test actions in its parser when an error token is in the look-ahead set. This prevents the parser from making undesirable reductions when an error occurs before the error is detected. The table format is different in eyacc than it was in the old yacc, as minor changes had been made for efficiency reasons.
