>            Priority: Minor

>
> Currently the expression engine can be set but not the interpolation.
> This patch proposes the ability to set a user specified interpolation engine.
> It includes a groovy interpolation engine. Groovy comes naturally as an expressions and interpolation language in the java environment
> API usage:
> 		AbstractConfiguration c = new PropertiesConfiguration("conf/test.conf");
> 		c.setInterpolator(new GInterpolator(c));
> 		System.out.println(c.getString("test"));
> Configuration examples:
> library.path.1=${ if  ("${System.getProperty{('os.name')}".toLowerCase().startsWith("windows")) "libw.dll"; else "libl" }
> password=${println 'enter password'; readln}
> I think that this is more feature rich than JEXL and is easier to use for java programmers.
