Resolution: fixed

Category: documentation

Bug description

The online manual says that the lexer returned by Genlex.make_lexer may raise Parse_error (I suppose that it should be interpreted as Parsing.Parse_error), but this is not what the implementation does (true in 4.00.0 as well as 4.00.1)

let lex = Genlex.make_lexer [];;

val lex : char Stream.t -> Genlex.token Stream.t =

let foo = Stream.of_string "()";;

val foo : char Stream.t =

let bar = lex foo;;

val bar : Genlex.token Stream.t = bar;;

Exception: Stream.Error "Illegal character (".
