If you have not installed Homebrew yet, please copy and past the following code to terminal to install Homebrew: $ /usr/bin/ruby -e "$(curl -fsSL )" We will also use Homebrew to install Haskell and Emacs here. If you are using Windows, you can download the single installer for everything provided by my professor Aaron Stump from here. There are some tricky things we need to notice in order to be able to use Haskell Mode on Mac.

In this blog post, I will talk about how to install Haskell and Emacs on Mac. Our professor asked us to use Emacs to edit all the Haskell and Agda code since there are plugins such as Haskell Mode that can let Emacs highlight Haskell code and compile them when needed. I learned how to use it in my Programming Language Concepts class. Haskell is a purely functional programming language. Install Haskell and Emacs on macOS May 20 2018
