Things You Should Know

• No dependencies are required so all you have to do is add zipscript-core.jar to your classpath.
• The default resource loading behavior is shown below can be modified: click here for details
• The ZipEngine is used to retrieve templates or evaluators

Zipscript Usages

Evaluating config entries as booleans

the default boolean evaluation resource loader assumes the expression is passed to the getEvaluator method

String expression = "foo != null && bar > 10"; // get the expression to evaluate
Map context = new HashMap();
// add business data to the context
try {
    Evaluator e = ZipEngine.createInstance().getEvaluator(expression);
    boolean val = e.booleanValue(context);
}
catch (ParseException e) {
// the expression was invalid
}

Retrieving runtime objects using config entries

the default object evaluation resource loader assumes the expression is passed to the getEvaluator method

String expression = "{foo, bar, baz}"; // get the expression to evaluate - example represents a list
Map context = new HashMap();
// add business data to the context
try {
    Evaluator e = ZipEngine.createInstance().getEvaluator(expression);
    Object obj = e.objectValue(context);
    // in this example obj will be a java.util.List
}
catch (ParseException e) {
// the expression was invalid
}

Merging templates with runtime data

the default template resource loader will retrieve the template resource from the classpath

String templateName = ... 
Map context = new HashMap();
// add business data to the context
try {
    Template t = ZipEngine.createInstance().getTemplate(templateName);
    // there are other merging options as well
    String result = t.merge(context);
}
catch (ParseException e) {
// the expression was invalid
}
