callHackage: make 'all-cabal-hashes' repository overridable This commit changes callHackage to use a deterministic version of the Hackage checkout from https://github.com/commercialhaskell/all-cabal-hashes by default. This means that packages uploaded to Hackage after today will be available to callHackage only after "pkgs/data/misc/hackage/default.nix" has been updated. People who want the previous behavior where we always had the latest version of Hackage available -- at the cost of frequent downloads from Github --, can add the following override to their "~/.nixpkgs/config.nix" file: { packageOverrides = super: { all-cabal-hashes = builtins.fetchTarball "https://github.com/commercialhaskell/all-cabal-hashes/archive/hackage.tar.gz"; }; } 2016-11-01 17:29:43 +00:00			`{ pkgs, stdenv, ghc, all-cabal-hashes`
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 08:19:56 +01:00			`, 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 19:27:32 +01:00			`, 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 12:24:11 +01:00			`, 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 18:21:19 +01:00
