The <link xlink:href="http://haskell.org/">Haskell</link>
|
|
packages infrastructure has been re-designed from the ground up
|
|
("Haskell NG"). NixOS now distributes the latest
|
|
version of every single package registered on
|
|
<link xlink:href="http://hackage.haskell.org/">Hackage</link> --
|
|
well in excess of 8,000 Haskell packages. Detailed instructions
|
|
on how to use that infrastructure can be found in the
|
|
<link xlink:href="https://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell-infrastructure">User's
|
|
Guide to the Haskell Infrastructure</link>. Users migrating from
|
|
an earlier release may find helpful information below, in the
|
|
list of backwards-incompatible changes. Furthermore, we
|
|
distribute 51(!) additional Haskell package sets that provide
|
|
every single <link xlink:href="http://www.stackage.org/">LTS
|
|
Haskell</link> release since version 0.0 as well as the most
|
|
recent <link xlink:href="http://www.stackage.org/">Stackage

Nightly</link> snapshot. The announcement

Haskell packages by name. The only packages visible in the

global scope are <literal>ghc</literal>,

but all other packages are hidden. The reason for this

inconvenience is the sheer size of the Haskell package set.

Name-based lookups are expensive, and most

<literal>nix-env -qa</literal> operations would become much

slower if we'd add the entire Hackage database into the top

level attribute set. Instead, the list of Haskell packages can

Previous versions of NixOS came with a feature called
|
|
<literal>ghc-wrapper</literal>, a small script that allowed GHC
|
|
to transparently pick up on libraries installed in the user's
|
|
profile. This feature has been deprecated;
|
|
<literal>ghc-wrapper</literal> was removed from the
|
|
distribution. The proper way to register Haskell libraries with
|
|
the compiler now is the
|
|
<literal>haskellPackages.ghcWithPackages</literal> function. The

locally. OpenBLAS has replaced ATLAS in most packages which use
