/* parser generated by jison 0.4.18 */
/ *
Returns a Parser object of the following structure :
Parser : {
yy : { }
}
Parser . prototype : {
yy : { } ,
trace : function ( ) ,
symbols _ : { associative list : name == > number } ,
terminals _ : { associative list : number == > name } ,
productions _ : [ ... ] ,
performAction : function anonymous ( yytext , yyleng , yylineno , yy , yystate , $$ , _$ ) ,
table : [ ... ] ,
defaultActions : { ... } ,
parseError : function ( str , hash ) ,
parse : function ( input ) ,
lexer : {
EOF : 1 ,
parseError : function ( str , hash ) ,
setInput : function ( input ) ,
input : function ( ) ,
unput : function ( str ) ,
more : function ( ) ,
less : function ( n ) ,
pastInput : function ( ) ,
upcomingInput : function ( ) ,
showPosition : function ( ) ,
test _match : function ( regex _match _array , rule _index ) ,
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 )
}
