Markdown string interpolation

Markdown.scala

package org.streum.interpol

/* Here is the interpolator itself, we just add a method `md`
   to the `StringContext` using implicit conversions */

object Markdown {
  
  implicit class MDContext( val context: StringContext ) extends AnyVal {

    // I used knockoff markdown processor. I don't have any real experience with
    // it but it looks very good
    import com.tristanhunt.knockoff.DefaultDiscounter._ 

    // args will contain the value that will be interpolated
    def md( args: Any* ) = {
      //Here we use the standard interpolation first
      val interpolated = context.s(args:_*)
      //We then call knockoff to process the resulting string      
      toXHTML( knockoff( interpolated ) )
    }

  }
