@@ -53,22 +53,6 @@ would actually also make the following point gracefully handled (status of
YYERRCODE, YYUNDEFTOK, etc.). Possibly we could also define YYEMPTY (twice:
as a token and as a symbol). And YYEOF.
It seems to work well. Yet we have a weird case: the "error" token:
enum yysymbol_type_t
{
YYSYMBOL_YYEMPTY = -2,
YYSYMBOL_YYEOF = 0,
YYSYMBOL_error = 1,
YYSYMBOL_YYUNDEF = 2,
YYSYMBOL_YYACCEPT = 61,
...
YYSYMBOL_error looks weird. We should maybe rename this as
"YYSYMBOL_YYERROR", even though it should not be confonded with the YYERROR
macro.
** Consistency
YYUNDEFTOK is an internal symbol number, as YYTERROR.
But YYERRCODE is an external token number.
