the parseError function receives a 'hash' object with these members for lexer and parser errors: {

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)
