After building it, set the input text with input(), and call token() to get new tokens. The public attribute filename can be set to an initial filaneme, but the lexer will update it upon #line directives. c C s^ | | _ | | _ | | _ | | _ d | _ d | _ t j d � | _ t j d � | _ d S( sb Create a new Lexer. error_func: An error function. Will be called with an error message, line and column as arguments, in case of an error during lexing. on_lbrace_func, on_rbrace_func: Called when an LBRACE or RBRACE is encountered (likely to push/pop type_lookup_func's scope) type_lookup_func: A type lookup function.
