#+begin_quote
|
|
Haskell contends with C and Ruby as my favorite language. I don't think my Haskell code will ever save the world, but I'll reach for it for small projects and programming exercises (like projecteuler.com or exercism.io).
|
|
|
|
I'd love to incorporate more of it into my machine learning work, but Python and Julia hold that crown. For now.

* Install
|
|
** Haskell
|
|
To get started with Haskell, you need *stack* installed.
|
|
|
|
*** MacOS
|
|
#+BEGIN_SRC sh :tangle (if (doom-system-os 'macos) "yes")
|
|
brew install haskell-stack
|
|
stack setup
|
|
#+END_SRC
|
|
|
|
*** Arch Linux
|
|
#+BEGIN_SRC sh :dir /sudo:: :tangle (if (doom-system-os 'arch) "yes")
|
|
sudo pacman --needed --noconfirm -S stack
|
|
# Replace pacaur with your AUR package manager of choice
|
|
pacaur --needed --noconfirm -S ncurses5-compat-lib
|
|
stack setup
|
|
#+END_SRC
|
|
|
|
** Dependencies
|
|
This module requires ~ghc-mod~ (as well as ~intero~, but those will be automatically installed).
|
|
|
|
#+BEGIN_SRC sh
|
|
stack install ghc-mod
|
|
#+END_SRC
|
|
|
|
Also ensure that ~\~/.local/bin~ is in ~PATH~:
|
|
|
|
#+BEGIN_SRC sh
|
|
# place this in your profile file, like ~/.bash_profile or ~/.zshenv
|
|
export PATH="~/.local/bin:$PATH"
|
|
#+END_SRC
|
|
|
|
* Troubleshooting
|
|
+ Stack users: if a ~dist/setup-config~ file exists in your project, [[ https://github.com/DanielG/ghc-mod/wiki#known-issues-related-to-stack][ghc-mod may
|
|
refuse to work]].
|
|
|
|
* Resources
|
|
Here are a few resources I've found indespensible in my Haskell adventures:
|
|
|
|

|

+ [[http://haskellbook.com/][Haskell Programming from first principles]]
