[antlr-interest] from antrl-generated AST back to java-file?

[Matthew Ford]

Here is a sample of what I use to output statements from a tree (after
transforming them)

statement
{ String str,lhsStr;
 }

 : #(as:ASSIGN_EXPR lhsStr=identOrConstant str = expression)
  {
   Output.out(lhsStr + " " + as.getText() + " " + str + "; //
ASSIGN_EXPR",debug);
  }

expression returns [String str]
{ str = "";
 }
 : (
   #(EXPRESSION (str=operator | str=identOrConstant | str=just_expression) )
  | str=operator
  | str=identOrConstant
  )
 ;
