So we should provide a function that directly provides you with the
token name from its number. I don't feel confortable when exhibiting
such low-level details.
However, if you don't want to wait for a release with this feature,
you can use these values:
/// Constants.
enum
{
yyeof_ = 0,
yylast_ = 1, ///< Last index in yytable_.
*** yynnts_ = 2, ///< Number of nonterminal symbols.
yyfinal_ = 3, ///< Termination state number.
yyterror_ = 1,
yyerrcode_ = 256,
*** yyntokens_ = 4 ///< Number of tokens.
};
The documentation you are referring to is really the documentation
of the C skeleton.
Cheers!
