Re: Haskell and guix

[David Craven]

So for future reference, to hack on a haskell package these are the steps:

guix environment haskell-package --ad-hoc cabal-install
unset GHC_PACKAGE_PATH
export GUIX_LD_WRAPPER_ALLOW_IMPURITIES=y
cabal update
cabal sandbox init
cabal install --only-dependencies --enable-tests
cabal build
