Hakyll + Stack + Nix

Prelude

This is my first post. Hello, world!

In this post we are going to walk through my blog platform setup with Hakyll, Stack and Nix.

Some links you might want to explore beforehand:

• Hakyll Github Pages Tutorial by Hakyll’s author
• Hakyll’s Home Page
• Hakyll Presentation and demo by Hakyll’s author
• Nix/NixOS Homepage
• Github Pages Homepage

Intruduction

So this should be something similar to our end result: a place where to write your blog posts.

This post is basically just following this and turning on stack’s nix functionality.

This is desireable because non-haskell dependancies are solved in the case of adding any.

Steps

0. I am using NixOS 19.09 with stack 1.9.3 taken from the 19.03 channel

1. Follow this tutorial until you’ve hit

   stack new myblog hakyll-template

2. Use resolver: lts-12.26 on stack.yaml

3. Then append this to stack.yaml

   nix:
     enable: true
     pure: true
     shell-file: shell.nix

4. Create shell.nix with this code, and change the name to correspond to whatever name you want

   { pkgs ? import <nixpkgs> {}, ghc ? pkgs.ghc }:
   
   pkgs.haskell.lib.buildStackProject {
     name = "blog.hhefesto.com";
     inherit ghc;
     buildInputs = with pkgs; [ zlib
                                haskellPackages.hakyll
                                gmp
                                # Any external dependancy you need may go here
                                # search https://nixos.org/nixos/packages.html?channel=nixos-19.09
                                # for the dependancy you're looking for and just add it
                              ];
     LANG = "en_US.UTF-8";
     TMPDIR = "/tmp";
   }
