TL;DR (bash script edition)

If you want to get started quickly, run the following. Read below for more information.

brew install --cocoa --srgb emacs
brew install the_silver_searcher

mkdir -p tmp
pushd tmp

mkdir -p ~/.local/bin
echo 'export PATH=$HOME/.local/bin:$PATH' >> ~/.bashrc && source ~/.bashrc #replace bashrc if you use a different shell
curl http://s3.dbp.io/stack-binary-2015-10-23.tar.gz | tar xz
mv stack-binary/stack ~/.local/bin && rmdir stack-binary
chmod +x ~/.local/bin/stack

popd
rmdir tmp

pushd ~
stack install hlint stylish-haskell
git clone git@github.com:dbp/emacs-config .emacs-config
cd .emacs-config && make

popd

Emacs

Install Emacs 24.5 from http://emacsformacosx.com.

brew install the_silver_searcher for a faster grep - it is used by our emacs config.

Much more is on the [[Emacs|Emacs]] page!

Alternately, you can also use brew to install emacs: brew install --cocoa --srgb emacs ~Matt

Haskell

There is a book we have: haskell-programming-v0.7.0.pdf

And another one!

Stack

Stack is a project / dependency management tool similar to bundler for Ruby.

You can download stack from:

http://s3.dbp.io/stack-binary-2015-10-23.tar.gz

• Check your PATH: echo $PATH. If it doesn't have /Users/you/.local/bin then: mkdir -p ~/.local/bin && echo 'export PATH=$HOME/.local/bin:$PATH' >> ~/.bashrc && source ~/.bashrc (replace .bashrc with .zshrc if you use zsh!).
• Unzip the binary and move the program inside the resulting folder to ~/.local/bin: tar xvzf stack-binary-2015-10-23.tar.gz && mv stack-binary/stack ~/.local/bin
• Make sure it is executable: chmod +x ~/.local/bin/stack

Setup of environment

Advice as of 2015/10/23 (dbp)!!!

• Before you run stack, setup the resolver version by creating ~/.stack/global/stack.yaml with the following content:

flags: {}
packages: []
extra-deps: []
resolver: lts-3.10

• Setup stack (downloads GHC, the haskell compiler) by running stack setup.

• Install hlint (good style suggestions) and stylish-haskell (automatic reformatting): cd ~ && stack install hlint stylish-haskell

• Get emacs config: git clone git@github.com:dbp/emacs-config (you can put it anywhere).

• Install emacs config: cd emacs-config && make

Now start emacs and it should install and set up stuff to make Haskell work. The first time you open a project it'll install a bunch of stuff.
