haskell: have a dedicated file for non Hackage packages We had a few "overrides" in configuration-common.nix that were really extensions. They introduced packages that weren't in hackage-packages.nix. The advantage of having a dedicated file for these packages is that we can still place Nix-specific overrides to these packages in configuration-nix.nix. We weren't able do this before because configuration-nix.nix extended only the packages from hackage-packages.nix. 2018-08-25 13:24:41 +00:00			`, nonHackagePackages ? import ./non-hackage-packages.nix`
haskellPackages: make configuration-{nix,common}.nix configurable The motivation is to be able to get rid of common configuration when initial packages differs since common configuration assumes a very specific version set. cc @jmitchell @peti 2017-06-22 11:24:11 +00:00			`, configurationCommon ? import ./configuration-common.nix`

haskell infra: Misc cleanups - The haskell lib is very close to not relying on Nixpkgs. I think this is good---simpler to think about and matches Nixpkgs's lib. - The haskell lib is only imported once - stdenv is exposed more shallowly so it can be overriden more easily. I'll eventually use this on Darwin to avoid the Sierra shared library problems (unless changes are to be made system-wide).

haskell: add support for all of Hackage The function "callHackage <name> <version>" generates build instructions for the requested library version on-the-fly. All of Hackage is available. Note: this code is brand-new, experimental, and it might change in the future. Don't base production code on this feature yet. Example usage: $ nix-shell -p 'haskellPackages.callHackage "cpphs" "1.19.3" {}' --run "cpphs --version" cpphs 1.19.3 $ nix-shell -p 'haskellPackages.ghcWithPackages (self: [(self.callHackage "hsdns" "1.6.1" {})])' --run "ghc-pkg list hsdns" /nix/store/p6r81k2vb2pzy4wcvri6z9m492i0hg63-ghc-8.0.1/lib/ghc-8.0.1/package.conf.d hsdns-1.6.1 2016-06-11 17:21:19 +00:00

haskell-modules: refactor package set This change is effectively a no-op to nixpkgs. However, it gives users the flexibility to create and maintain their own package sets per project, while benefiting from nix's Haskell configurations. I would make immediate use of this change in stack2nix, a project that generates nix expressions for all the dependencies of a given Haskell project. @domenkozar is familiar with the motivations and helped refine this change 2017-05-30 18:27:32 +00:00			`package-set = initialPackages;`
