[microsling] Making the Resource in Javascript a little bit more JSON-like

Hi,

I started playing with microsling yesterday and found so far two  
itches in the Javascript template approach used by microsling that I  
would like to scatch:

1) Syntax highlighting for ESP: http://weblogs.goshaky.com/weblogs/ 
lars/entry/esp_javascript_template_language_syntax
2) Making the Javascript objects used in ESP-templates like resource  
and resource.item a little bit easier to handle by wrapping them in  
ScriptableObjects. The ESP example could then be simplified to:

<%-- microsling ESP template example, store this as html.esp --%>
<html>
<body>
<p>This page is generated from an ESP template!</p>
<h1><%= resource.uri %></h1>
<%
   for each (var p in resource.item.properties) {
     %>
       <p>
         <%= p.name %>
         =
         <strong><%= p.string %></strong>
       </p>
     <%
   }
%>
</body>
</html>

Other ways of accessing a property could be:
resource.item.properties.foo
resource.item.properties["foo"]
resource.item.properties[1]

and the same API could apply to children. The idea is to expose the  
Resource (and the wrapped Node) as a JSON object that can be  
processed easily.

regards,

Lars

Great. I will write these objects and keep all the JCR methods, so  
the JCR-purists can use their Java-API.

Cool. Just one minor note: ESP is not actually inspired by JSTE as it is
used in Day's Communiqué product since the year 2001 :-)

Very true. This would in fact be some simplification, though the JCR
purist will of course not like it :-)

I would invite you to contribute such host objects. What do you think ?
Unfortunately, it has been some years (yes it was 2001) since I did my
last ScriptObject implementation ...
