# Learn Functional Programming course/tutorial on Scala [](https://travis-ci.org/dehun/learn-fp) [](https://travis-ci.org/dehun/learn-fp) # ## Intro ## This course/tutorial was created with purpose to better understand functional programming idioms using Scala language. It covers type classes, monoids, functors, applicatives, monads, traversable/foldable, monad transformers, free monad. Material is structured as set of stub/unimplemented functions/classes and tests for them. Your objective is to make all unit tests green. It is learn-by-doing course. ## Example session ##  ## Inspiration ## NICTA course was a great and interesting challenge for me to do in Haskell. I think Scala community will benefit from the similar course. ## Target audience ## The material in here is quite poor on theoretical/explanation part. I have tried to link material from other authors that I have found to be good into this course Readme to compensate for this. Some prior experience with functional idioms is recommended, but not necessary. ## How to start ## Just git clone this repository and follow steps in progression section. You can use any IDE and verify your results using `sbt test`. For me intellij works best - you can easily run individual tests out of it. In case if you got stuck - check answers branch. ## Progression ## It is important to keep the progression - a lot of things depend on each other. Implementing something = making all tests green for that thing. ### Type classes ### - Observe general type class pattern in `learnfp/typeclass/TypeClass.scala`. - Implement `learnfp/typeclass/TotalOrder.scala` - Implement `learnfp/typeclass/Show.scala` - Implement `learnfp/typeclass/Eq.scala` - Extra material: - https://blog.scalac.io/2017/04/19/typeclasses-in-scala.html ### Monoids ### - Observe general monoid pattern in `learnfp/monoid/Monoid.scala` - Implement `learn-fp/src/main/scala/learnfp/monoid/ListMonoid.scala` - Implement `learn-fp/src/main/scala/learnfp/monoid/SimpleMonoid.scala` - Implement `learnfp/monoid/PairAdditiveMonoid.scala` - Extra material: - Bartosz Milewski: Category Theory 3.1: Examples of categories, orders, monoids ### Functors ### - Observe general functor pattern in `learnfp/functor/Functor.scala` - Implement `learnfp/functor/Id.scala` - Implement `learnfp/functor/Maybe.scala` - Implement `learnfp/functor/List.scala` - Implement `learnfp/functor/Disjunction.scala` - Implement `learnfp/functor/Writer.scala` - Implement `learnfp/functor/State.scala` - Extra material: - http://learnyouahaskell.com/functors-applicative-functors-and-monoids - https://thedet.wordpress.com/2012/04/28/functors-monads-applicatives-can-be-so-simple/ - Bartosz Milewski: Category Theory 6.1: Functors ### Monads ### - Observe general monad pattern in `learnfp/monad/Monad.scala` - Implement `learnfp/monad/Id.scala` - Implement `learnfp/monad/Maybe.scala` - Implement `learnfp/monad/List.scala` - Implement `learnfp/monad/Disjunction.scala` - Implement `learnfp/monad/Writer.scala` - Implement `learnfp/monad/State.scala` - Extra material - Brian Beckman: Don't fear the Monad - http://eed3si9n.com/learning-scalaz/Monad+transformers.html ### Foldable ### - Implement foldable in `learnfp/foldable/Foldable.scala` ### Applicatives ### - Observe general applicative pattern in `learnfp/applicative/Applicative.scala` - Implement `learnfp/applicative/Id.scala` - Implement `learnfp/applicative/Maybe.scala` - Implement `learnfp/applicative/List.scala` - Implement `learnfp/applicative/Disjunction.scala` - Implement `learnfp/applicative/Writer.scala` - Implement `learnfp/applicative/State.scala` - Extra material - https://en.wikibooks.org/wiki/Haskell/Applicative_functors - http://eed3si9n.com/learning-scalaz/Applicative
