Haskell training: 101 and 102.

This repository contains the source for the slides and the exercises used in the Haskell trainings at Google. Haskell is not one of the internally "blessed" languages, but a dedicated team of volunteers is making use of 20% time to try to make Haskell at Google possible! This set of lessons was created in 2016, to allow newcomers to the language to get involved with the team.

Slides

The slides use LaTeX. Simply run make to create the PDFs, assuming you have all the required dependencies.

You need xelatex and the Yanone Kaffeesatz fonts installed on your machine.

On an Ubuntu system, you can get all of these by running

sudo apt-get install texlive-xetex texlive-fonts-extra fonts-yanone-kaffeesatz

Exercises

The codelabs only require ghc to be installed and in the path as well as one of Stack or Cabal. Step-by-step instructions will be provided to guide you through the installation process, at the point where these tools will be necessary. In case you already have them installed, running make in each codelab directory will identify which of the tool is installed and use that to build the exercises as well as run the test.

There is also a possiblity to run the codelabs using Docker. See the instructions in the codelab directories.

To solve an exercise, you need to replace codelab with the actual implementation. For the 101 course, each different codelab directory (except 00_setup which is only used to test installation) has a src/Codelab.hs where you would need to do the exercises. For the 102 course, all the exercises are in the same directory in multiple files, given that we are building a full project. Consult the slides for instructions on how to run each codelab.

We also provide solutions, in the same directory as the corresponding exercise.

Recordings

Public recordings of the training (in an old format) are available: Haskell 101, Haskell 102.

Release

See the releases to download the generated PDFs and the codelabs.
