In this blog post, I will talk about how to install Haskell and Emacs on Mac. There are some tricky things we need to notice in order to be able to use Haskell Mode on Mac. If you are using Windows, you can download the single installer for everything provided by my professor Aaron Stump from here. Nov 02, 2018 On Mac, Stack is available from Homebrew. To make things even more interesting, I decided to test Visual Studio Code. While I’m not charmed by Code, it provides a solid Haskell support via Haskell Syntax Highlighting and Haskell ghc-mod packages. It gave me type hints, auto-completion, and allowed for running GHCI (Haskell’s. Download Windows Migration Assistant v2.4.0.0 (Monterey) This software will help you migrate data from a Windows PC running Windows. The Migration Assistant will launch automatically after it has been installed.

Download WinGhci - A simple graphical user interface for the GHCi (Glasgow Haskell Compiler interactive environment) that should make coding more comfortable.

Extension for Visual Studio Code - Provides language support via ghc-mod in VS Code. If you already use Emacs/Vim/Visual Studio Code/Atom/Sublime, they have good Haskell support so you can continue using them. If you don't, you should know that the Emacs vs. Vim war has been going on for a long, long time, and you should seek the answer elsewhere.

What is the least painful way to get Haskell and a modern, user-friendly development environment set up ?Based on my periodic attempts to set up the available Haskell IDEs, and to support newcomers on IRC,as of early 2016 it's stack and Atom(unless you're on a mac and willing to pay and be in a slightly walled garden, in which case it's Haskell for Mac).

Here are some basic recipes for setting up Haskell and Atom from scratch, on any of the major platforms, as reliably and easily as possible.They briefly note the steps required, and also the results you can expect (something that's often unclear with Haskell IDEs).You don't need any previous Haskell knowledge, but you will need to download things, run terminal commands, wait for builds, edit files and configure settings.With a fast connection/machine and the hints below, it should take less than half an hour, most of that unattended.

This doc can evolve if you test it yourself and send pull requests (quick feedback via IRC is also welcome).Note as of late 2016 I have moved from Atom to Intellij (similar features, more refined and robust)and I've stopped updating this doc myself.

If it is obsolete or there's a much better place for it, let me know.I hope you find it useful.

Table of Contents

Set up Haskell

  1. Install Stack, (Haskell build tool): http://haskell-lang.org/get-started
  2. Add Stack's bin directory to your PATH if possible.
  • Eg: echo 'export PATH=$HOME/.local/bin:$PATH' >> ~/.bashrc
  1. Install a default instance of GHC (Haskell compiler) for your user:
  • stack setup

Create a minimal program in terminal (Optional)

in a terminal/command/shell window:

Test your program interactively in terminal (Optional)

Set up Atom

  1. install tools: stack install ghc-mod hlint stylish-haskell # slow

  2. install Atom (text editor & IDE): http://atom.io

  3. start Atom

  4. install plugins: Atom Preferences -> Install

    • search for haskell

      • install language-haskell, ide-haskell, ide-haskell-repl and haskell-ghc-mod
    • search for term3

      • install term3
  5. configure plugins: Atom Preferences -> Packagages

  • ide-haskell
    • nothing ?
  • ide-haskell-repl
    • Command Args: ghci
    • Command Path: stack # or the stack executable's absolute path, eg /usr/local/bin/stack. Don't use ~.
  • haskell-ghc-mod
    • Additional Path Directories: ... # eg on mac: /Users/USERNAME/.local/bin, /usr/local/bin

View your program in Atom

  1. File -> Open, select hello.hs (or other file you like)
  2. Haskell IDE -> Toggle Panel hides/shows Error/Warning/Lint/... panes

With an module open, you should see:

  • Syntax or type errors highlighted in place and reported in the Error pane
  • Hhlint cleanup suggestions highlighted in place and reported in the Lint pane
  • Auto-completion when typing both Haskell keywords (module, let, etc) and local names

Troubleshooting

  • Haskell IDE -> Prettify gives an error:

    • stylish-haskell may not be in your path if Atom was started from GUI. Try starting from terminal (on mac: open -a Atom)
    • The file parsing failed due to, for example, misplaced code
  • if Haskell IDE -> Prettify does nothing, chances are it is already prettified

Test your program interactively in Atom

While viewing hello.hs, do Haskell IDE -> Open REPL and after you should see a new pane with a *Main> prompt.

Enter GHCI commands here using CTRL-enter or CMD-enter:

:main # or any Haskell expression
:reload # after saving changes in hello.hs
:help
:quit

Run terminal commands in Atom

You can also run regular GHCI in a terminal pane:

Packages -> Term 3 -> Open New Terminal In Right Pane (eg)

Create a program, package and project

Git

  • In the terminal: stack new hello simple
  • In Atom: File -> Open, select and open the hello directory (with no file selected)

Haskell For Windows

  • If errors are not highlighted in open files on starting Atom
    • File -> Save will wake it up (haskell-ghc-mod/#142)
  • If errors are reported but the file compiles without error at the command line
    • in multi-package stack projects, haskell-ghc-mod (ghc-mod) requires a workaround (ghc-mod/#787)
