lexer/parser interface

In order to able to compute line and colums numbers, the lexer is supposed to:

  • use Lxm.make to return a lexeme to the parser
  • use newline to add a new line
Sourceval new_line : Lexing.lexbuf -> unit
Sourceval make_string : Lexing.lexbuf -> t
Sourceval add_pragma : t -> pragma list -> t

compiler interface

Sourcetype 'a srcflagged = {
  1. src : t;
  2. it : 'a;
}

used to attach a source information to a lexeme

Sourceval flagit : 'a -> t -> 'a srcflagged
Sourceval last_made : unit -> t

Returns the last created lexem. Useful to locate syntax errors.
