symbols_: {associative list: name ==> number},
terminals_: {associative list: number ==> name},
productions_: [...],

next: function(),
lex: function(),
begin: function(condition),
popState: function(),
_currentRules: function(),
topState: function(),
pushState: function(condition),
options: {
ranges: boolean (optional: true ==> token location info will include a .range[] member)
flex: boolean (optional: true ==> flex-like lexing behaviour where the rules are tested exhaustively to find the longest match)
backtrack_lexer: boolean (optional: true ==> lexer regexes are tested in order and for each matching regex the action code is invoked; the lexer terminates the scan when a token is returned by the action code)
},
performAction: function(yy, yy_, $avoiding_name_collisions, YY_START),
rules: [...],
conditions: {associative list: name ==> set},

token location info (@$, _$, etc.): {
first_line: n,
last_line: n,
first_column: n,
last_column: n,
range: [start_number, end_number] (where the numbers are indexes into the input string, regular zero-based)
}
the parseError function receives a 'hash' object with these members for lexer and parser errors: {
text: (matched text)
token: (the produced terminal token, if any)
line: (yylineno)
}
while parser (grammar) errors will also provide these members, i.e. parser errors deliver a superset of attributes: {
loc: (yylloc)
expected: (string describing the set of expected tokens)
recoverable: (boolean: TRUE when the parser has a error recovery rule available for this particular error)
}
