flow-comprehensions

This project is still very much in development, but we are publishing builds to JCenter.

You can try a work-in-progress version by adding the following to your build.sbt:

libraryDependencies += "org.scala-comprehensions" %% "flow-comprehensions" % "0.0.3"

For sbt 0.13.11+, also add:

useJCenter := true

Scala flow-comprehensions are a simpler and more powerful alternative to Scala's built-in for-comprehension syntax.

Scala:

for{
  i <- List(1,2,3)
  j <- List(2,3,4)
} yield i*j

Flow:

sequence[List]{
  val i = ~List(1,2,3)
  val j = ~List(2,3,4)
  i*j
}

Scala:

for{
  i <- List(1,2,3)
  j <- List(2,3,4)
  if i > 2
} yield i*j

Flow:

sequence[List]{
  val i = List(1,2,3).value
  val j = List(2,3,4).value
  i*j
}
