  15 <p>Code to solve the <a href="http://adventofcode.com/2016/">Advent of Code</a> puzzles. This year, I'm trying to use the puzzles as a prompt to learn <a href="https://wiki.haskell.org/Haskell">Haskell</a>.</p>
  16 <p><a href="http://learnyouahaskell.com/chapters">Learn you a Haskell</a>, <a href="https://www.haskell.org/tutorial/index.html">Introduction to Haskell 98</a>, and <a href="https://hackage.haskell.org/">Hackage</a> are good resources.</p>
  17 <h1 id="toolchain">Toolchain</h1>
  18 <p>I'm using the basic Haskell Platform installation, togeher with <code>Stack</code> to manage the packages and dependencies (install with</p>
  19 <pre><code>$ sudo aptitude install haskell-platform haskell-stack</code></pre>
  20 <p>).</p>
  21 <p>I have one package for each day, to save time waiting for Stack to check every executable before compiling what's changed. Each package needs a separate directory tree and a separate <code>.cabal</code> file.</p>
  22 <p>To work on a project, <code>cd</code> into that project's directory.</p>
  23 <p>Compile with</p>
  24 <pre><code>stack build</code></pre>
  25 <p>or</p>
  26 <pre><code>stack build adventofcode1601</code></pre>
  27 <p>Run with</p>
  28 <pre><code>stack exec advent01</code></pre>
  29 <p>Run interactively with</p>
  30 <pre><code>stack ghci adventofcode1601:exe:advent01</code></pre>
  31 <p>To profile, use</p>
  32 <pre><code>stack build --executable-profiling --library-profiling --ghc-options=&quot;-fprof-auto -rtsopts&quot; adventofcode1601</code></pre>
  33 <p>then run with</p>
  34 <pre><code>stack exec -- advent01 +RTS -p -hy</code></pre>
  35 <h1 id="readme">Readme</h1>
  36 <p>Build this readme file wth</p>
  37 <pre><code>pandoc -s README.md &gt; README.html</code></pre>
  38 <h3 id="earlier-instructions-for-compiling-before-use-of-stack">Earlier instructions, for compiling before use of Stack</h3>
  39 <p>I'm also using some extra libraries. Before installing, run <code>cabal update</code> then set <code>library-profiling: True</code> in <code>~/.cabal/config</code> . Then install the packages with</p>
  40 <pre><code>$ cabal install MissingH
  41 $ cabal install parsec-numbers
  42 $ cabal install cryptonite
  43 $ cabal install pqueue</code></pre>
  44 <p>Compile the code with</p>
  45 <pre><code>ghc --make advent01.hs</code></pre>
  46 <p>then run it as</p>
  47 <pre><code>advent01</code></pre>
  48 <p>If you're profiling, compile and run with</p>
  49 <pre><code>ghc -O2 --make advent01.hs -prof -auto-all -caf-all -fforce-recomp -rstopts
  50 time ./advent01 +RTS -p -hy</code></pre>
  51 <p>and create the profile picture with <code>h2ps advent01.hp</code> .</p>
