Upgrading to monad-control-0.3
by Nicolas Pouillard 03 Jan '12

03 Jan '12

Hello, To package the latest and greatest version of git-annex I need to have monad-control-0.3. However this depend on the update of yesod and would break mongoDB as well. I'm quite short on times these days and would like to know if this is gonna happen soon or not? In the meantime I email the author of the mongoDB haskell package. All the best, -- Nicolas Pouillard http://nicolaspouillard.fr

Latest yesod/mime-mail combination is broken?
by Andrew Myers 28 Dec '11

28 Dec '11

Hi all, Is that latest Yesod + mime-mail broken or am I doing something stupid? I can install everything just fine but when I do > yesod init > Project Name: test > Foundation: Test > cd test > cabal configure I get Resolving dependencies... Configuring test-0.0.0... cabal: At least the following dependencies are missing: mime-mail >=0.3.0.3 && <0.4 However > pacman -Ss haskell-mime-mail haskell/haskell-mime-mail 0.3.0-3 [installed] Compose MIME email messages. Note the '-' in the third place where there was a '.' in the third place on the 'cabal configure' command. If I 'cabal install' mime-mail this only results in more confusion and breakage for cabal, as you might expect. > cabal install 'mime-mail <0.4' Resolving dependencies... (... Snip ...) Registering mime-mail-0.3.0.3... > cabal configure Resolving dependencies... Configuring personal-website-0.0.0... Warning: This package indirectly depends on multiple versions of the same package. This is highly likely to cause a compile failure. package mime-mail-0.3.0 requires dataenc-0.13.0.4 package mime-mail-0.3.0.3 requires dataenc-0.14.0.3 package yesod-auth-0.7.5 requires mime-mail-0.3.0 package personal-website-0.0.0 requires mime-mail-0.3.0.3 It seems I can't use the current version of yesod that's in the Arch Haskell repositories because of this. Any suggestions? Thanks, Andrew

And here we disagree :-) My impression is that there is no *testing* in HP at all, instead they choose the latest stable version of GHC and a set of packages at versions that fit together, sometimes they are the most recent most often they aren't. Some choices are even outright questionable, like OpenGL. IMNSHO haskell platform only makes sense for systems that lack a proper packaging system, where it makes available a convenient installer. As I understand "the Arch way" it means using the *latest* stable release. A good example of this is the move to python3. I think Haskell shouldn't be treated in any other way. /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus Most software today is very much like an Egyptian pyramid with millions of bricks piled on top of each other, with no structural integrity, but just done by brute force and thousands of slaves. -- Alan Kay

How to determine whether a package is in or out in [haskell]?
by Magnus Therning 20 Dec '11

20 Dec '11

Now we have 300+ packages in [haskell]. It's starting to be a large set, and the time required to build when something changes is starting to really be felt now. So I would like to start a discussion on how we should decide what criteria to use when adding a package, and equally important, what criteria to use when dropping a package. My _impression_ is that additions have been a bit willy-nilly. Guided only by what the maintainers fancy at the moment. I also don't think that we've ever dropped a package, ever. I feel it's important to me to know that the resources I put into ArchHaskell is appreciated, and every added package increases the resources required. I therefore would like to know that each and ever package in [haskell] is there for a good reason. I feel I need to bring this up because there are a few packages in [haskell] that I suspect are there, but aren't widely used. To point fingers, the chief reason is Agda :) This is a package that has a mere 13 votes in AUR, and it takes more than an hour to build it on my laptop (about 70 minutes to be more precise). On each platform! So, what are our options when it comes to deciding what's in and what's out? Any thoughts? Oh, and can I please drop Agda in the meantime? ;) /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus I invented the term Object-Oriented, and I can tell you I did not have C++ in mind. -- Alan Kay

Profiling

Hello, do we really need profiling for every installed package? We could reduce compiling time and disk space usage by 1/3rd. Fabio

Haskell Support Was: Xmonad version?
by Bernardo Barros 17 Dec '11

17 Dec '11

Haskell platform was released with the latest stable GHC (7.0.4 of course). Guys, what's happening with haskell support in Arch? Xmonad, and now GHC and lots of packages in the supported repos are not keeping update with upstream.

Fwd: [Haskell-cafe] Announce: The Haskell Platform 2011.4
by Bernardo Barros 17 Dec '11

17 Dec '11

---------- Forwarded message ---------- From: Don Stewart <dons00(a)gmail.com> Date: Sat, Dec 17, 2011 at 1:04 PM Subject: [Haskell-cafe] Announce: The Haskell Platform 2011.4 To: haskell(a)haskell.org, haskell-cafe <haskell-cafe(a)haskell.org>, "haskell-platform(a)projects.haskell.org" <Haskell-platform(a)projects.haskell.org> We're pleased to announce the release of the Haskell Platform: a single, standard Haskell distribution for everyone. Download the Haskell Platform 2011.4.0.0: http://haskell.org/platform/ The specification, along with installers (including Windows, Apple and Unix installers for a full Haskell environment) are available. The Haskell Platform is a single, standard Haskell distribution for every system, in the form of a blessed library and tool suite for Haskell distilled from the thousands of libraries on Hackage, along with installers for a wide variety of systems. It saves developers work picking and choosing the best Haskell libraries and tools to use for a task. When you install the Haskell Platform, you get the latest stable compiler, an expanded set of core libraries, additional development tools, and cabal-install – so you can download anything else you need from Hackage. What you get is specified here: http://hackage.haskell.org/platform/contents.html Thanks! -- The Platform Infrastructure Team P.S. Special thanks to Mark Lentczner for his excellent work on this release. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe(a)haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
