Jessop

Jessop is a polyglot templating language in the style of Java Server Pages (JSPs).

Like all templating languages, output can be any text stream ( e.g. English text, HTML/CSS or other text-based programming or markup languages), but the statements, conditions and expressions within the language can be written in any language that the Java scripting engine ( javax.script ) supports.

e.g. by enabling the 'javascript' target language, you can embed javascript code within your jessop script (which executes using the 'rhino' engine), or by enabling the 'python' target language, you can embed python code within your jessop script (which executes using the 'jython' engine).

The jessop syntax should be familiar to anyone who has written JSPs. A file may contain

• a declaration in the form

<%@ jessop language="javascript" engine="rhino" %>

• expressions to generate output in the form

<%= name %>

• scriptlets to execute arbitrary code in the form

<% if (name==null) { %>
    
    No name
    
<% } %>

See the Javadoc overview for a more complete description of the jessop syntax.
