The problem is that after an error token has arrived in the input,
additional reductions can take place before an error is issued by the
parser. So, although errors are detected, they are issued at a point
hampering good error recovery.
That's e

I would know the expected token in a parser (GLR also..l) when yyerror

if the string in input is "ad$", in yyerror I would capture correct

Hi
I would know the expected token in a parser (GLR also..l) when yyerror
function is invoked. For example:
A = aB | bB
B = b | c
etc
if the string in input is "ad$", in yyerror I would capture correct tokens
expected...like b or c.
Ho I can make that?
Many Thanks
Bye
