Verfied that the upload of the ghc bindist was cut short. New upload in progress! I've double checked and the build of Platform, and it's upload is fine.

HP 2015.2.0.0 and GHC 7.10
by Mark Lentczner 28 Mar '15

28 Mar '15

I've gone ahead and built a very provisional, alpha version of 2015.2.0.0 using GHC 7.10 RC3. I bumped all the GHC libs to the versions in 7.10, and bumped all the Platform libs to the latest versions I could find on Hackage. There were a few issues: - *old-locale and old-time* - no longer part of GHC, but cabal-install, cgi & HTTP need them - and they are part of the platform - so included now as added packages. Not sure this is a great idea, since they are now very deprecated... but until cabal-install, cgi, & HTTP update, not sure what else to do. - *tf-random* - is now required by alex and QuickCheck - seems a shame to add this, as now we're going to have two random packages - *network-uri *- was split out of network, and needed by cabal-install, cgi, & HTTP. I suppose we should include it, as it was functionality and API that was part of the platform - *exceptions* & *multipart* - needed by cgi - is exceptions now subsumed by something in transformers? and... multipart? maybe time to drop cgi? We didn't have it last time anyway as it wouldn't compile! - *scientific* - needed by attoparsec - debated in detail last time ... and we're still here! The Platform is significantly larger now: On OS X it has gone from 316M to 499M! Most of this is due to new OpenGL libs which are now huge (went from 98M to 239M!) GHC itself grew by 109M (to almost 1G), so that the whole installed magilla is 1.5G! Even the compressed installer is now 250M! If you want to poke at it, the source is in the pre-release branch at GitHub <https://github.com/haskell/haskell-platform/tree/pre-release>, and the OS X builds are at my usual platform staging area: Index of /mark/platform <http://www.ozonehouse.com/mark/platform/> Remember, it already includes GHC, so no need to download the GHC binary for OS X that is there, too. I'll try to get a generic linux build up soonish... but my VM now runs out of memory trying to build OpenGL - and adding more only makes my machine thrash to death! - Mark

Re: [commit: ghc] master: Rename driver phases C(obj)cpp to C(obj)cplusplus (abde5da)

Hi Thomas, Cplusplus is quite long identifier, bad for eyes. Usually in C++ community if you can't use cpp then you use cxx. It's shorter and clear even when reading fast, don't you think? Karel PS: of course even before cxx it was CC, but I think this does not have any advantage over cxx in this context...

ANNOUNCE: GHC version 7.10.1
by Austin Seipp 27 Mar '15

27 Mar '15

============================================================== The (Interactive) Glasgow Haskell Compiler -- version 7.10.1 ============================================================== The GHC Team is pleased to announce a new major release of GHC. There have been a number of significant changes since the last major release, including: * Several new language features and changes have been implemented: - Applicative is now a superclass of Monad and in the Prelude. - Many prelude combinators have been generalized - Static pointers * GHC now has preliminary and experimental support for DWARF based debugging. * `integer-gmp` has been completely rewritten. * Type-checking plugins can now extend the type checker. * Support for partial type signatures * Many bugfixes and other performance improvements. * Preliminary support for 'backpack' features like signatures. * Typeable is now generated by default for all data types automatically. We've also fixed a handful of issues reported since RC3: - A bug in the call arity analysis that would result in invalid core was fixed (#10176) - A bug in the Win32 package causing it to fail to load was fixed (#10165) - ghc-prim has (correctly) been bumped to version 0.4.0.0, to comply with the PVP. - Several libraries have been bumped to their latest available versions after coordination. The full release notes are here: https://downloads.haskell.org/~ghc/7.10.1/docs/html/users_guide/release-7-1… How to get it ~~~~~~~~~~~~~ The easy way is to go to the web page, which should be self-explanatory: https://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://ghc.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: https://ghc.haskell.org/trac/ghc/wiki/Platforms https://ghc.haskell.org/trac/ghc/wiki/CodeOwners Ports to other platforms are possible with varying degrees of difficulty. The Building Guide describes how to go about porting to a new platform: https://ghc.haskell.org/trac/ghc/wiki/Building 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: https://ghc.haskell.org/trac/ghc/ Mailing lists ~~~~~~~~~~~~~ We run mailing lists for GHC users and bug reports; to subscribe, use the web interfaces at https://www.haskell.org/mailman/listinfo/glasgow-haskell-users https://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 https://www.haskell.org/mailman/listinfo/ Some GHC developers hang out on #haskell on IRC, too: https://www.haskell.org/haskellwiki/IRC_channel Please report bugs using our bug tracking system. Instructions on reporting bugs can be found here: https://www.haskell.org/ghc/reportabug Hashes & Signatures ~~~~~~~~~~~~~~~~~ On https://downloads.haskell.org/~ghc/7.10.1/ you will find a signed copy of the SHA256 hashes for the tarballs, using my GPG key (0F8F 3AA9 9235 C704 ADA0 B419 B942 AEE5 3B58 D86F). -- Regards, Austin Seipp, Haskell Consultant Well-Typed LLP, http://www.well-typed.com/

wither the Platform
by Mark Lentczner 27 Mar '15

27 Mar '15

I'm wondering how we are all feeling about the platform these days.... I notice that in the new Haskell pages, the Platform is definitely not the recommended way to go: The main download pages suggests the compiler and base libraries as the first option - and the text for the Platform (second option) pretty much steers folks away from it. Of the per-OS download pages, only the Windows version even mentions it. Does this mean that we don't want to consider continuing with it? It is a lot of community effort to put out a Platform release - we shouldn't do it if we don't really want it. That said, I note that the other ways to "officially get" Haskell look, to my eye, very ad hoc. Many of the options involve multiple steps, and exactly what one is getting isn't clear. It hardly looks like there is now an "official, correct" way to setup Haskell. The Platform arose in an era before sandboxes and before curated library sets like Stackage and LTS. Last time we set direction was several years ago. These new features and development have clearly changed the landscape for use to reconsider what to do. I don't think the status quo for the Platform is now viable - mostly as evidenced by waning interest in maintaining it. I offer several ways we could proceed: *1) Abandon the Platform.* GHC is release in source and binary form. Other package various installers, with more or less things, for various OSes. *2) Slim the Platform.* Pare it back to GHC + base + a smaller set of "essential" libs + tools. Keeps a consistent build layout and installation mechanism for Haskell. *3) Re-conceive the Platform.* Take a very minimal install approach, coupled with close integration with a curated library set that makes it easy to have a rich canonical, stable environment. This was the core idea around my "GPS Haskell" thoughts from last September - but there would be much to work out in this direction. Thoughts? — Mark
