   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 To work on a project, `cd` into that project's directory.
  21
  22 Compile with
  23 ```
  24 stack build
  25 ```
  26 or
  27 ```
  28 stack build adventofcode1601
  29 ```
  30
  31 Run with
  32 ```
  33 stack exec advent01
  34 ```
  35
  36 Run interactively with
  37 ```
  38 stack ghci adventofcode1601:exe:advent01
  39 ```
  40
  41 To profile, use
  42 ```
  43 stack build --executable-profiling --library-profiling --ghc-options="-fprof-auto -rtsopts" adventofcode1601
  44 ```
  45 then run with
  46 ```
  47 stack exec -- advent01 +RTS -p -hy
  48 ```

  50 # Readme
  51
  52 Build this readme file wth
  53 ```
  54 pandoc -s README.md > README.html
  55 ```
  56
  57 ### Earlier instructions, for compiling before use of Stack
  58
  59 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
  60 ```
  61 $ cabal install MissingH
  62 $ cabal install parsec-numbers
  63 $ cabal install cryptonite
  64 $ cabal install pqueue
  65 ```
  66
  67 Compile the code with
  68 ```
  69 ghc --make advent01.hs
  70 ```
  71
  72 then run it as
  73 ```
  74 advent01
  75 ```
  76
  77 If you're profiling, compile and run with
  78 ```
  79 ghc -O2 --make advent01.hs -prof -auto-all -caf-all -fforce-recomp -rstopts
  80 time ./advent01 +RTS -p -hy
  81 ```
  82
  83 and create the profile picture with `h2ps advent01.hp` .
