[antlr-interest] error in my rule...

[Vaida Morkute]

Hello,

Could you help me to understand what is wrong in my rule:

query!
	:SELECT! a:selection_list
             {## = #([QUERY, "query"], #(SELECT, a));}
         (WHERE! b:where_list
             {## = #([QUERY, "query"], #(SELECT, a),#(WHERE, b));})?
	;

As output I want to get an AST of the form:
	#(QUERY #(SELECT a) #(WHERE b)), where
	QUERY is imaginary note and WHERE is optional.

How could I rewrite this rule?


After the compilation I get the following errors:

BandParser.java:63: cannot resolve symbol
symbol  : variable tmp1_AST
location: class band.BandParser
query_AST = (AST)astFactory.make( (new 
ASTArray(2)).add(astFactory.create(QUERY,"query")).add((AST)a
stFactory.make( (new ASTArray(2)).add(tmp1_AST).add(a_AST))));
                                      ^

(new ASTArray(2)).add(SELECT).add(a_AST))).add((AST)astFactory.make( (new 
ASTArray(2)).add(tmp2_AST).add(b_AST))));
                ^

(new ASTArray(2)).add(SELECT).add(a_AST))).add((AST)astFactory.make( (new    
                      ASTArray(2)).add(tmp2_AST).add(b_AST))));
^

I am stuck at this place :( ... I would appreciate your help very much,

Vaida :)
