View topic - Haskell vs Prolog, or "Giving Haskell a choice" I've become more and more familiar with Haskell, and more and more have I begun to realize its true potential. It's truly frightening, really. One of the things I've started to realize is how well it can adapt different programming paradigms without sacrificing its functional purity.Another language I'm quite fond of is Prolog, and I'm actually somewhat sad I haven't spent more time hacking in it.That said, I decided to try a little experiment: writing Prolog in Haskell, staying as true to Prolog as possible, and see if the forced paradigm breaks it. I'll be rather thorough in explaining how things work for the benefit of the Prolog and Haskell illiterates out there, so if you're familiar with both you might want to tl;dr, or just bask in the glory that is Prolog and Haskell combined. At first this might seem somewhat difficult. Prolog doesn't have functions or procedures, but predicates.
Beginning Haskell Before you start About this tutorial This tutorial targets programmers of imperative languages wanting to learn about functional programming in the language Haskell. In an introductory tutorial, many of Haskell's most powerful and complex features cannot be covered. awesome Haskell: Hoogle FTW you know Hoogle – don’t you? In case you don’t Hoogle is a search-engine where you can look for Haskell functions. You can use with it’s web-interface and there are a couple of plugins (for GHCi, etc.)
Become a Programmer, Motherfucker If you don't know how to code, then you can learn even if you think you can't. Thousands of people have learned programming from these fine books: Learn Python The Hard Way Neil Mitchell - HLint HLint (formerly Dr. Haskell) reads Haskell programs and suggests changes that hopefully make them easier to read. HLint also makes it easy to disable unwanted suggestions, and to add your own custom suggestions. Running the tool over the darcs source code, we can generate an interactive report with --report, or view the results in the console:
Composing Reactive Animations Conal Elliott Microsoft Research Graphics Group Copyright 1998 We have all seen a lot of wonderful looking computer graphics, and many of us have spent time playing video games or watching our kids (or their kids) play them. It is clear that computer graphics, especially interactive graphics, is an incredibly expressive medium, with potential beyond our current imagination.
Learn Haskell Fast and Hard tl;dr: A very short and dense tutorial for learning Haskell. Thanks to Oleg Taykalo you can find a Russian translation here: Part 1 & Part 2 ; Table of Content I really believe all developers should learn Haskell. Testing, proving, checking – How to verify code properties As programmers we often want to express that a special property holds for a method, e.g. we want to say that the associativity law holds for list concatenation. In F# we could define a concat method like this: As programmers we could write a couple of unit tests which try to check the associativity law. With NUnit enabled we could write this: But the question is: did we cover all interesting cases?
