Functional Vilnius #9 Haskell workshop

This guide will prepare on setting up your computer for the workshop.

Installing Haskell

We recommend to install Haskell locally on your computer instead of using a VM, because you can then use your favourite text editor and a familiar environment. If, however, you are having issues with doing so, we will provide an Ubuntu-based Vagrant VM, see below on Using Vagrant.

The easiest way to do so is using stack.

Installing stack

stack is a tool for building Haskell projects and managing dependencies, including installing the GHC Haskell compiler itself. It is essentially a wrapper around an older and 'lower-level' Haskell build tool called cabal.

stack is available on most platforms, please follow the official guides from stack on how to install it on your OS.

Next, you should install GHC via stack.

Installing GHC

The Glasgow Haskell Compiler (GHC) is the 'default' Haskell compiler, which we will use.

To install it, simply run:

stack setup 7.10

This might take a while.

Using Vagrant

• Install VirtualBox

• Install Vagrant

• First, obtain this repository, either via git:

  git clone https://github.com/functional-vilnius/fpv9-haskell-workshop

or simply by downloading the zip archive and extracting it.

From within the fpv9-haskell-workshop/huskysay directory run:

cd fpv9-haskell-workshop/huskysay
vagrant up

Finally run

    vagrant ssh

to enter the VM.

Editor integration

We won't need any fancy IDE features during the workshop, so feel free to use any text editor you prefer. If you're not sure what to use, Atom has quite decent Haskell support.
