   6 Code to solve the [Advent of Code](http://adventofcode.com/2016/) puzzles. This year, I'm trying to use the puzzles as a prompt to learn [Haskell](https://wiki.haskell.org/Haskell).
   7
   8 [Learn you a Haskell](http://learnyouahaskell.com/chapters), [Introduction to Haskell 98](https://www.haskell.org/tutorial/index.html), and [Hackage](https://hackage.haskell.org/) are good resources.

  10 # Toolchain
  11
  12 I'm using the basic Haskell Platform installation, togeher with `Stack` to manage the packages and dependencies (install with
  13 ```
  14 $ sudo aptitude install haskell-platform haskell-stack
  15 ```
  16 ).
  17
  18 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 `.cabal` file.
  19
  20 Compile with
  21 ```
  22 stack build
  23 ```
  24 or
  25 ```
  26 stack build adventofcode1601
  27 ```
  28
  29 Run with
  30 ```
  31 stack exec advent01
  32 ```
  33
  34 Run interactively with
  35 ```
  36 stack ghci adventofcode1601:exe:advent01
  37 ```
  38
  39 To profile, use
  40 ```
  41 stack build --executable-profiling --library-profiling -ghc-options="-fprof-auto -rtsopts" adventofcode1601
  42 ```
  43 then run with
  44 ```
  45 stack exec -- advent01 +RTS -p -hy
  46 ```
  47
  48 # Readme
  49
  50 Build this readme file wth
  51 ```
  52 pandoc -s README.md > README.html
  53 ```
  54
  55 ### Earlier instructions, for compiling before use of Stack
  56
  57 I'm also using some extra libraries. Before installing, run `cabal update` then set `library-profiling: True` in `~/.cabal/config` . Then install the packages with
  58 ```
  59 $ cabal install MissingH
  60 $ cabal install parsec-numbers
  61 $ cabal install cryptonite
  62 $ cabal install pqueue
  63 ```
  64
  65 Compile the code with
  66 ```
  67 ghc --make advent01.hs
  68 ```
  69
  70 then run it as
  71 ```
  72 advent01
  73 ```
  74
  75 If you're profiling, compile and run with
  76 ```
  77 ghc -O2 --make advent01.hs -prof -auto-all -caf-all -fforce-recomp -rstopts
  78 time ./advent01 +RTS -p -hy
  79 ```
  80
  81 and create the profile picture with `h2ps advent01.hp` .
