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"; }; }

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
