Jan Helwich has done a great job of describing how to use Scalate with Play 2.0. He’s even provided an example Play 2.0 project which uses Scalate. This post contains step-by-step instructions for a new project based on his work.

For convenience, I’ve also wrapped these changes up as a patch that can be applied to a new Play 2.0 project. Apply it with git am --signoff play20-with-scalate.patch.

1. Create a new Play project.

   play new myproject
   # choose "1 - Create a simple Scala application"
   

2. Add Scalate to your project dependencies in project/Build.scala

   val appDependencies = Seq(                                                   
     // Add your project dependencies here,                                     
     "org.fusesource.scalate" % "scalate-core" % "1.5.3"                        
   )    
   

3. Place a copy of Jan Helwich’s ScalateIntegration.scala in app/lib

   curl -o app/lib/ScalateIntegration.scala https://raw.github.com/janhelwich/Play-2-with-Scala-and-Scalate/master/app/controllers/ScalateIntegration.scala
   

4. Set the default Scalate template type in conf/application.conf.

   # Default Scalate template format (mustache, scaml, jade, ssp)
   scalate.format=jade
   

5. Create a layout and a template.

app/views/layouts/default.jade

    -@ var body: String
    -@ var title: String = "Page"

    !!!5
    html
      head
        title= title
      body
        != body

app/views/index.jade

    -@ var title: String = "Page"

    h1= title

5. Use your templates in a controller.

   package controllers
   
   import play.api._
   import play.api.mvc._
   
   object Application extends Controller {
     def index = Action {
       Ok(Scalate("index.jade").render('title -> "Hello world!"))
     }
   }
   

Done! Try out your app with play run
