Adam Heath commented on JANINO-91:
----------------------------------
But how do I then have static declarations? I'd like to be able to create static helper methods, and static variables, inside the ScriptEvaluator. Like this:
==
import java.util.HashMap;
import java.util.Map;
static final String CONSTANT_VALUE = "foobarbaz";
static Map toMap(Object[] args) {
if (args.length % 2 != 0) throw new IllegalArgumentException("even number of args expected");
Map result = new HashMap();
for (int i = 0; i < args.length; ) {
Object key = args[i++];
Object value = args[i++];
result.put(key, value);
}
return result;
}
webslinger.event("/Path/To/Event", toMap(new Object[] {"key", "value"}));
return null;
==
Additionally, the reason I needed the whitespace, is that when I parse the above, I remember the imports, find all leading static declarations, then save the rest; I then use string manipulation to insert the package and class name declarations, *without* changing any line numbers. This latter is important, so that stack traces give correct line numbers, for debugging purposes.

> I have code that filters package/import stmts from source files, then wraps the remaining code in a class definition. To keep line numbers identical after adding the class definition, I need to have comments and whitespace parsed an return to my application. The attached patch does this.
