You should to import DreadLocks code at the top on your program.

import org.scalalites.dreadlocks._

The DreadLocks temlate engine allows ${...} and #{...} syntax to evaluate the variable, and <?sc ... ?> syntax is evaluated as statements, like foreach, if-else etc. You can see some examples below. There are many exmaples in src/test/resources/ and src/test/scala/, please see them.

template_variable.shtml: ${title} #{body}

TemplateVariable.scala: // You can specify instance of java.io.File, scala.io.Source or String to constructor of Template class. val input = Source.fromFile("template_variable.shtml").getLines.mkString val template = Template(input) val context = Context("title" -> "Welcome to DreadLocks", "body" -> "DreadLocks project are hosted on scalalites.org.") val output = template.render(context)

// <html>
//    <head>
//        <title>Welcome to DreadLocks</title>
//    </head>
//    <body>DreadLocks project are hosted on scalalites.org.</body>
// </html>

ex. Examples that evaluate iterable variables and if-else statement.

hamburgers.txt Delicious hamburger restraunts in Japan: <?sc restraunts.foreach { restraunt => ?> * ${restraunt} <?sc } ?>

Side menus:
<?sc if(haveSideMenu) { ?>
    * ${sideMenus("potato")}
    * ${sideMenus("coleslaw")}
<?sc } ?>

Complex.scala // You can specify instance of java.io.File, scala.io.Source or String to constructor of Template class. val source = Source.fromFile("template_variable.shtml") val template = Template(source) val context = Context("restraunts" -> List("Baker Bounce", "Great Burger", "FELLOWS"), "haveSideMenu" -> true, "sideMenus" -> HashMap("potato" -> "French fries", "coleslaw" -> "Coleslaw"))

val output = template.render(context)
// Console.println(output)
// Delicious hamburger restraunts in Japan:
//   * Baker Bounce
//   * Great Burger
//   * FELLOWS
// Side menus:
//   * French fries
//   * Coleslaw
