Subject: [Caml-list] ocamlyacc bug?
Date: Tue, 22 Apr 2003 15:06:31 +0900 [thread overview]
Message-ID: <002101c30895$52410cd0$fe00a8c0@hama> (raw)
Is the following an ocamlyacc bug?
When making application with using ocamlyacc + ocamllex,
you can make main function in trailer part (after second "%%") of "foo.mly"
It that case, it generates an error like this:
This expression has type Lexing.lexbuf -> Eg_parse.token
but is here used with type Lexing.lexbuf -> token
It can be fixed by excluding type specification of start non-terminal
function in "foo.ml" like this:
(before)
let line (lexfun : Lexing.lexbuf -> token) (lexbuf : Lexing.lexbuf) =
(yyparse yytables 1 lexfun lexbuf : int)
(after)
let line lexfun (lexbuf : Lexing.lexbuf) =
(yyparse yytables 1 lexfun lexbuf : int)
