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)
