1) Packages formerly called haskell-haskell-platform-ghcXYZ-VVVV.X.Y.Z are
now called haskell-platform-VVVV.X.Y.Z. The latest version can be
installed by running "nix-env -i haskell-platform".
2) The attributes haskellPackages_ghcXYZ.haskellPlatform no longer exist.
Instead, we have attributes like haskellPlatformPackages."2012_4_0_0".
(The last numeric bit must be quoted when used in a Nix file, but not on
the command line to nix-env, nix-build, etc.) The latest Platform has a
top-level alias called simply haskellPlatform.
3) The haskellPackages_ghcXYZ package sets offer the latest version of every
library that GHC x.y.z can compile. For example, if 2.7 is the latest
version of QuickCheck and if GHC 7.0.4 can compile that version, then
haskellPackages_ghc704.QuickCheck refers to version 2.7.
4) All intermediate GHC releases were dropped from all-packages.nix to
simplify our configuration. What remains is a haskellPackages_ghcXYZ set
for the latest version of every major release branch, i.e. GHC 6.10.4,
6.12.3, 7.0.4, 7.2.2, 7.4.2, 7.6.3, 7.8.2, and 7.9.x (HEAD snapshot).
5) The ghcXYZPrefs functions in haskell-defaults.nix now inherit overrides
from newer to older compilers, i.e. an override configured for GHC 7.0.4
will automatically apply to GHC 6.12.3 and 6.10.4, too. This change has
reduced the redundancy in those configuration functions. The downside is
that overriding an attribute for only one particular GHC version has become
more difficult. In practice, this case doesn't occur much, though.
6) The 'cabal' builder has a brand-new argument called 'extension'. That
function is "self : super : {}" by default and users can override it to
mess with the attribute set passed to cabal.mkDerivation. An example use
would be the definition of darcs in all-packages.nix:
| darcs = haskellPackages.darcs.override {
| cabal = haskellPackages.cabal.override {
| extension = self : super : {
| isLibrary = false;
| configureFlags = "-f-library " + super.configureFlags or "";
| };
| };
| };
In this case, extension disables building the library part of the package
to give us an executable-only version that has no dependencies on GHC or
any other Haskell packages.
The 'self' argument refers to the final version of the attribute set and
'super' refers to the original attribute set.
Note that ...
- Haskell Platform packages always provide the Haddock binary that came with
the compiler.
- Haskell Platform 2009.2.0.2 is broken because of build failures in cgi and
cabal-install.
- Haskell Platform 2010.1.0.0 is broken becasue of build failures in cgi.
The function ‘mkDerivation’ now checks whether the current platform
type is included in a package's meta.platform field. If not, it
throws an exception:
$ nix-build -A linux --argstr system x86_64-darwin
error: user-thrown exception: the package ‘linux-3.10.15’ is not supported on ‘x86_64-darwin’
These packages also no longer show up in ‘nix-env -qa’ output. This
means, for instance, that the number of packages shown on
x86_64-freebsd has dropped from 9268 to 4764.
Since meta.platforms was also used to prevent Hydra from building some
packages, there now is a new attribute meta.hydraPlatforms listing the
platforms on which Hydra should build the package (which defaults to
meta.platforms).

By now, it happened twice that a commit broke GHC and thus all Haskell packages
we have in Nixpkgs. On such an occasion, I receive well in excess of 3000
notification e-mails from Hydra, and then I receive another 3000 e-mails after
the bug has been fixed. Under these circumstances, subscribing to these
notifications makes no sense for me.

* haskell-mkcabal: updated to version 1.0.0
* haskell-ghc-syb-utils: updated to version 0.2.1.0
* haskell-darcs: updated to version 2.5.2
svn path=/nixpkgs/trunk/; revision=28449
Several changes, some highlights:
* Structure of haskell-packages.nix updated. It's now easier to
select different default versions of packages for different
versions of GHC.
* GHC 7.0.2 is now default.
* Haskell Platform 2011.2.0.0 has been added and is now default.
* Several packages have been updated
(gtk2hs, gitit, xmonad, darcs, ...).
* Some old packages have been removed.
svn path=/nixpkgs/trunk/; revision=26288
* Updated Darcs to 2.2.1 and switched to the Cabal builder. However,
there are some dependencies missing that Andres will add :-)
svn path=/nixpkgs/trunk/; revision=15128
* added an experimental fetchdarcs function, based on fetchsvn
(there are no expressions yet that use this function)
