Subject: Error location reporting in Menhir
Date: Fri, 30 Mar 2007 15:02:06 +0100 [thread overview]
Message-ID: <7DE6C068-8889-4A8E-9C98-66471DDD9878@gmail.com> (raw)
I currently retrieve location like this during parser errors:
let rhs_loc n = (Parsing.rhs_start_pos n, Parsing.rhs_end_pos n)
I then report it like this:
let syntax_error s num =
parser_error s (rhs_loc num)
In my grammar I report errors like this:
| INPUT COLON input_decs error { syntax_error "Missing semicolon" 4 }
I don't do anything special in the lexer to adjust lexeme positions.
How do I rewrite my error reporting for Menhir?
Thanks, Joel
