At the request of the Haskell Platform folks, we are shipping the Data Parallel Haskell libraries separately from GHC (i.e., they are not bundled in the GHC distribution, nor will they be bundled in any Haskell Platform distribution). To use DPH with GHC 7.2.1, you need to install the DPH libraries separately from Hackage — for details, see http://pls.posterous.com/data-parallel-haskell-and-repa-for-ghc-721 Manuel Ian Lynagh:

============================================================= The (Interactive) Glasgow Haskell Compiler -- version 7.2.1 =============================================================

The GHC Team is pleased to announce a new major release of GHC, 7.2.1.

The 7.2 branch is intended to be more of a "technology preview" than normal GHC stable branches; in particular, it supports a significantly improved version of DPH, as well as new features such as compiler plugins and "safe Haskell". The design of these new features may evolve as we get more experience with them. See the release notes for more details of what's new and what's changed.

We are also using this branch as an opportunity to work out the best workflows to use with git.

We expect the 7.2 branch to be short-lived, with 7.4.1 coming out shortly after ICFP as normal.

Full release notes are here:

How to get it ~~~~~~~~~~~~~

The easy way is to go to the web page, which should be self-explanatory:

http://www.haskell.org/ghc/

We supply binary builds in the native package format for many platforms, and the source distribution is available from the same place.

Packages will appear as they are built - if the package for your system isn't available yet, please try again later.

Background ~~~~~~~~~~

Haskell is a standard lazy functional programming language.

GHC is a state-of-the-art programming suite for Haskell. Included is an optimising compiler generating good code for a variety of platforms, together with an interactive system for convenient, quick development. The distribution includes space and time profiling facilities, a large collection of libraries, and support for various language extensions, including concurrency, exceptions, and foreign language interfaces (C, whatever). GHC is distributed under a BSD-style open source license.

A wide variety of Haskell related resources (tutorials, libraries, specifications, documentation, compilers, interpreters, references, contact information, links to research groups) are available from the Haskell home page (see below).

On-line GHC-related resources ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Relevant URLs on the World-Wide Web:

GHC home page http://www.haskell.org/ghc/ GHC developers' home page http://hackage.haskell.org/trac/ghc/ Haskell home page http://www.haskell.org/

Supported Platforms ~~~~~~~~~~~~~~~~~~~

The list of platforms we support, and the people responsible for them, is here:

http://hackage.haskell.org/trac/ghc/wiki/Contributors

Ports to other platforms are possible with varying degrees of difficulty. The Building Guide describes how to go about porting to a new platform:

Developers ~~~~~~~~~~

We welcome new contributors. Instructions on accessing our source code repository, and getting started with hacking on GHC, are available from the GHC's developer's site run by Trac:

http://hackage.haskell.org/trac/ghc/

Mailing lists ~~~~~~~~~~~~~

We run mailing lists for GHC users and bug reports; to subscribe, use the web interfaces at

http://www.haskell.org/mailman/listinfo/glasgow-haskell-users http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

There are several other haskell and ghc-related mailing lists on www.haskell.org; for the full list, see

http://www.haskell.org/mailman/listinfo/

Some GHC developers hang out on #haskell on IRC, too:

Ticket #3356 claims that {-# LANGUAGE NoTraditionalRecordSyntax #-} was implemented in 7.2.1. But GHCi v7.2.1 complains "Unsupported extension: NoTraditionalRecordSyntax". What (if anything) actually got implemented? I ask because I'd like to raise a ticket for http://hackage.haskell.org/trac/ghc/wiki/Records/DeclaredOverloadedRecordFie... /NoMonoRecordFields -- that is, to enable declaring within the same module multiple record types with the same field name. Of course it will also help when declaring the same field name in different (but imported) modules. Avoiding generating the (monomorphic) field selector function goes a little way towards freeing up the namespace, without in any way pre-judging how the 'narrow namespace issue' might get addressed.
