fancellu / PostProcessScalaxb.scala
Last active December 23, 2015 07:29
Quick app to postprocess source files. Created because Scalaxb was converting '-' to u45 in class names.
package com.felstar.playpen.scalaxb
import java.io.File
object PostProcessScalaxb {
def allFiles(path:File):List[File]= {
val (dirs,files)=path.listFiles.toList.partition(_.isDirectory)
files ::: dirs.flatMap(allFiles)
}

Scala Sunspot Interview question I was given. Here's the word doc question https://app.box.com/s/1e8ukxjr25f2luj99t2f
object SunSpot {
def main(args: Array[String]): Unit = {
type Cube = Array[Array[Int]]
def sumCube(arr: Cube):Int = arr map (_.sum) sum
def getSampleCube(cube: Cube, y: Int, x: Int): Cube = cube.slice(y - 1, y + 2) map (_.slice(x - 1, x + 2))
def toCube(st: String, size: Int): Cube = st.split(" ").map(_.toInt).grouped(size).toArray

Created February 28, 2014 17:48
Fix for better control over XML output. Hope this little tip helps.
val that= <that>x</that>
val thatcr= Seq(that,Text("\n"))
val xml= <root>
{ for (x<-1 to 4) yield that }
{ for (x<-1 to 4) yield

Last active August 29, 2015 13:57
Nice OO Scala example for a talk for Harvey Nash
object Rational extends App {
case class Rational(n: Int, d: Int=1) extends Ordered[Rational]{
require(d != 0)
private def gcd(a: Int, b: Int): Int = if (b == 0) a else gcd(b, a % b)
private val g = gcd(n.abs, d.abs)
val numer = n / g
val denom = d / g
def + (that: Rational) = Rational( numer * that.denom + that.numer * denom, denom * that.denom)
