Hi -
I am trying to parse a given java file, with a code fragment that consumes comments as below: ( Code fragment got from Java.g , pasted in the antlr site, to give credit where it is due).
COMMENT
@init{
boolean isJavaDoc = false;
System.out.println("Entering comment");
}
: '/*'
{
if((char)input.LA(1) == '*'){
isJavaDoc = true;
}
}
(options {greedy=false;} : . )*
'*/'
...
;
I am trying to get all the characters mapped by the wildcard regex , as in 'options greedy' line in the grammar file and get the string into the Java world for further processing. What hidden system variables/ grammar should I use to take care of the same ?
