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).

hackage-packages.nix: switch our default package set to Stackage Nightly This update was generated by hackage2nix v20150903-82-g351b6f8 using the following inputs: - Hackage: https://github.com/commercialhaskell/all-cabal-hashes/commit/af161fdf178e996c83d9c06059cb81cc4480b035 - LTS Haskell: https://github.com/fpco/lts-haskell/commit/da73308b6359aa6083591ec7a2069090977d3be7 - Stackage Nightly: https://github.com/fpco/stackage-nightly/commit/1994a4f865fe7e1cbe2c5b94a2214a5d91507f2c 2015-09-16 09:19:56 +02:00			`, compilerConfig ?

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 20:27:32 +02:00			`, initialPackages ? import ./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 13:24:11 +02:00			`, configurationCommon ? import ./configuration-common.nix`

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 19:21:19 +02:00
