KDom

A template engine with Handlebars.js style syntax and a DOM-like structure. Allows jquery paradigm in templates.

Usage:

    KParser k = new KParser();

    String html = "<!DOCTYPE html>\n"
            + "<html>"
            + "<title>XXX</title>"
            + "<body class='main'>"
            + "{{p.name}}BBB"
            + "<ul>"
            + "{{#customers}}"
            + "<li>"
            + "<h1>{{firstName}} {{surName}}</h1>"
            + "</li>"
            + "{{#addresses}}"
            + "<li>"
            + "<b>{{parent.firstName}} lives at {{line1}} {{city}}</b>"
            + "</li>"
            + "{{/addresses}}"
            + "{{/customers}}"
            + "</ul>"
            + "<br/>AAA\n"
            + "</body>"
            + "</html>";
    ByteArrayInputStream in = new ByteArrayInputStream(html.getBytes());
    KDocument page = k.parse(in);
    assertNotNull(page.getRoot());

    KDomTemplater t = new KDomTemplater( k.getJexl());
    Map vars = new HashMap();
    List<Customer> customers = new ArrayList<>();
    customers.add(new Customer("brad", "mac")); // customer gets created with 2 Addresses
    customers.add(new Customer("Joe", "Bloggs"));
    vars.put("customers", customers);
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    t.render(page, out, vars);

Want to use nested templates?

First implement your own template locator: TemplateLocator templateLocator = new TemplateLocator() {

    @Override
    public KDocument locate(String path) {
        return template;
    }
};

Specify a template in the above by changing like this: String html = "\n" + "" + "{{#template 'templates/page'}}" + "<title>XXX</title>"

KDomTemplater t = new KDomTemplater(templateLocator, k.getJexl()); // re-use jexl from the parser

Map vars = new HashMap();
List<Customer> customers = new ArrayList<>();
customers.add(new Customer("brad", "mac"));
customers.add(new Customer("Joe", "Bloggs"));
vars.put("customers", customers);
ByteArrayOutputStream out = new ByteArrayOutputStream();
t.render(page, out, vars);
