Issue 101 2018-04-05
Welcome to another issue of Haskell Weekly! Haskell is a safe, purely functional programming language with a fast, concurrent runtime. This is a weekly summary of what’s going on in its community.

February’s game jam set a theme of safety. Leveraging Elm’s type system helped make the experience of building a game much nicer.
This site will give a home to all the things we wanted to do but couldn’t fit into Joy. The core of the site will be video courses on Haskell, Nix, and related subjects.
rowdyhas the best of both worlds: you get compile-time guarantee by interpreting the DSL in a Template Haskell splice, so you can generate datatypes and functions.
I thought I’d take some time to respond to some of the concerns raised about my recent higher-kinded data and free lenses for higher-kinded data posts.
There are a couple different Haskell libraries out there for MailChimp. But we’re not going to use them! Instead, we’ll learn how we can use Servant to connect directly to the API.
I’m pretty excited about what this means for the Jupyter ecosystem and IHaskell in particular, and I’m looking forward to seeing what other people do with this!
In this series of posts I’m going to discuss some of the major design decisions that you will need to consider when making a Haskell roguelike game.
I have developed a Haskell API for both projects. In this post I will outline the differences between these projects and illustrate how to use them within Haskell.
Haskell can process flat files as though they were hierarchal with the help of lazy evaluation and one ridiculously clever one-line function.
The most important part is probably that we split up a component’s input into a model (its dependencies on other components) and a
Configwhich is introduced by the component itself.
The Semantic Code leader must have or quickly develop high level domain expertise within the fields of program analysis, programming language theory (PLT), parsing and computational semantics.
We are looking for a senior engineer who will work on building health and financial products to help patients.

Package of the week
This week’s package of the week is tree-traversals, a library providing in-order, pre-order, post-order, level-order, and reversed level-order traversals for tree-like types.
