GitHub Flavored Asciidoc (GFA)

Phoenix 1.4 ships with exciting new features, most notably with HTTP2 support, improved development experience with faster compile times, new error pages, and local SSL certificate generation. Additionally, our channel layer internals receiveced an overhaul, provided better structure and extensibility. We also shipped a new and improved Presence javascript API, as well as Elixir formatter integration for our routing and test DSLs.

This release requires few user-facing changes and should be a fast upgrade for those on Phoenix 1.3.x.

Introduction

I was recently asked to explain why I felt disappointed by Haskell, as a language. And, well. Crucified for crucified, I might as well criticise Haskell publicly.

First though, I need to make it explicit that I claim no particular skill with the language - I will in fact vehemently (and convincingly!) argue that I'm a terrible Haskell programmer. And what I'm about to explain is not meant as The Truth, but my current understanding, potentially flawed, incomplete, or flat out incorrect. I welcome any attempt at proving me wrong, because when I dislike something that so many clever people worship, it's usually because I missed an important detail.

Another important point is that this is not meant to convey the idea that Haskell is a bad language. I do feel, however, that the vocal, and sometimes aggressive, reverence in which it's held might lead people to have unreasonable expectations. It certainly was my case, and the reason I'm writing this.

Type classes

I love the concept of type class

	// the reasonable option

	::shadow .haskell .entity .module,
	::shadow .haskell .identifier .module {
	opacity: 0.5;
	}

	// the nuclear option

	::shadow .line:not(.cursor-line) .haskell .entity .module,

	import Data.Semigroup
	import Data.Functor
	import Control.Applicative

	data Validation err a = Failure err \| Success a
	deriving Show

	instance Functor (Validation err) where
	fmap f (Success a) = Success (f a)
	fmap _ (Failure e) = Failure e
