ElectricCoffee / SafeConvert.scala
Created September 6, 2014 14:33
Got a little miffed by the fact that str.toInt threw an exception if a non-convertible string was encountered (a-la "hello".toInt), so I figured it would make more sense if it returned an option instead, using this library you can do this: "hello".opt.toInt which would return None, saving you a tedious try/catch
package com.wausoft.extensions
object SafeString {
class StrOps(input: String) {
private def toOption[A](in: => A) = try {
Some(in)
} catch {
case _: Throwable => None
}

ElectricCoffee / MOption.scala
Created September 9, 2014 22:39
Adds map and flatMap as extension methods to Scala, for those who don't want/need scalaz for their project, is fully compatible with for-comprehensions
package extension.monad
trait Monad[A, M[_]] {
// >>= :: Monad m => m a -> (a -> m b) -> m b
def flatMap[B](input: A => M[B]): M[B] // AKA "bind"
}
trait Functor[A, F[_]] {
// fmap :: Functor f => (a -> b) -> f a -> f b
def map[B](input: A => B): F[B] // AKA "fmap"
