Development Dependencies

Currently, development of the Haskell track assumes that you are using GHC 7.8.3 with Haskell Platform installed. The following packages need to be installed if not using Haskell Platform:

$ comm -13 \
  <(ghc-pkg --global list --simple-output --names-only \
  | tr ' ' '\n') \
  <(find . -name '*.hs' \
  | xargs awk \
    '/^import/ {if ($2 == "qualified") {print $3} else {print $2}}' \
  | sort -u \
  | xargs -n1 ghc-pkg find-module --simple-output --names-only \
  | cut -d' ' -f1 \
  | sort -u)
