I just checked this into the git repository (with slight mods) so it
will be available in tomorrow's nightly build. Here's an example script:
<?xml version="1.0" encoding="UTF-8"?>
<isl debug="true" loop="1" offscreen="true" sleep="60.0minutes">
<for start="5" end="20" increment="2">
<echo message="printing index ${index}"/>
</for>
</isl>
I used "end" and "increment" instead of "limit" and "delta".
Thanks, Jeff.

Having just recently taken a stab @ ISL scripting, I can attest to its
utility and potential ... and it does make for much nicer looking text
rendering. But the key word is "potential" ... it currently lacks some
basic features of scripting languages ... such as the ability to set an
integer value and then increment it (very useful when creating an animation
loop).
Haven't actually tested this (but it compiles) but the following code would
add a for isl tag that looks like:
<for start="0" limit="10" delta="1">
....
</for>
protected boolean processTagFor(Element node) throws Throwable {
pushProperties();
List allValues = new ArrayList();
int numElements = 0;
int cnt = 1;
int start = XmlUtil.getAttribute(node, "start",0);
int limit = XmlUtil.getAttribute(node, "limit",0);
int delta = XmlUtil.getAttribute(node, "delta",1);
for(int i=start;i<limit;i+=delta) {
putProperty("index", ""+i);
try {
if ( !processChildren(node)) {
return false;
}
} catch (MyBreakException be) {
break;
} catch (MyContinueException ce) {}
}
popProperties();
return true;
}
