Hello all,
I am having trouble with yacc parser giving shift/reduce
conflict, while I do not see where the conflict can be.
I have simplified the grammar to the following one:
#lang racket
(require parser-tools/yacc
parser-tools/lex)
(define-empty-tokens my-tokens (EOF A B C))
(define (my-parser source-name)
(parser
(start start)
(end EOF)
(tokens my-tokens)
(error #f)
(grammar
(start ((x) $1))
(x
((y A B) (list $1 'ab)))
(y
((C) 'c)
((C A) 'ca)))))
It reports "1 shift/reduce conflict".
But from my primitive point of view, the parser should
accept only "CAB" and "CAAB" inputs, so there is no chance
for a conflict here. Could please anybody point me on what
is not correct with my understanding?
Best regards,
Dmitry
