Hello, I'm very happily learning Haskell with nix-shell and haskell-ng environment. In comparison to previous 'haskell', there is no problem at all.
But I've found problem that hdevtools does not see related build-depends options in cabal file. https://github.com/bitc/hdevtools/issues/38 So I would try patched hdevtools from fork. https://github.com/maximkulkin/hdevtools Cloned, checked out proper branch. What is next step? I've read quite many document. Wiki, nix pills, ... . But I'm confused about so many different ways doing similar things. And I'm worried about haskell-ng specific things. There is already 'haskellngPackages.hdevtools'. So I should override using ~/hdevtools. I'll attach my current setup information. Arch Linux nix-unstable Thanks. ~~~ $ nix-env -q cabal-install-1.22.0.0 cabal2nix-2.0 nix-1.8 nox-0.0.1 $ ls -1 cis194.cabal HW01.hs HW02.hs LICENSE Main.hs Setup.hs shell.nix Test.hs ... snip ... $ cat cis194.cabal -- Initial cis194.cabal generated by cabal init.
