My Scala Base - Adventures in Scala

I've been tweaking the Hibernate in Scala example from my previous post.

The experiment is to interleave the hbm.xml mapping information right into your plain old scala object code. Sort of like a poor man's annotation, so you can keep your meta information right snug up to your properties. This helps get around Scala's current limitations around deep annotations (so I heard).

Hibernate with Scala example in one file

Just worked through Hibernate's tutorial, but using Scala. Googling for hints turned up info from Matt Hellige's blog(s) and Viktor Klang from the lift web group. So with a tip of the hat to them, here's a working example of using Hibernate from Scala, in a single file. Enjoy...

import org.hibernate.cfg._



class Event {

  var id: Long = 0L 

  var title: String = null

  var date: Date = null 

  var p

Inline Scala Tables

Another whoa moment today -- ran across a pointed, concise Scala code snippet in Eric Torreborre's announcement of the specs 1.1 testing library...

 "provide an add operation" in {
 "a" | "b" | "result" |>
 1 ! 2 ! 3 |
 5 ! 2 ! 7 |
 3 ! 0 ! 3 | {
 (a: Int, b: Int, result: Int) => { calc.add(a, b) must_== result }
 }
 }
}

The above is a great e… Continue

Hmmm, Lift Uses Maven

While trying to get the latest version of the lift web framework (0.3.0) for Scala, I updated to maven 2.0.8, and then per the announcement instructions typed...
