[Caml-list] getting ocamlyacc to continue even after a parse error

[Rafael 'Dido' Sevilla]

How do I get ocamlyacc to generate a parser that continues parsing even
after an error?  I want to print all the errors in the code that's being
parsed.

As briefly mentioned in the ocamlyacc manual (section 12.4.4),
ocamlyacc, like Yacc, supports error recovery via so-called error
tokens and error productions.  You'd better consult a good book on
Yacc (such as Levine's _Lex&Yacc_), because using error productions
effectively is a bit of a black art.

Good luck.
