Re: [Haskell-cafe] Question about Newtype "op()" function arguments.

2013-06-12 Thread David Banas
Ah, so is the idea, then, to use *op()* when `n` wasn't actually constructed formally, but rather "assembled" by the user, so as to match the type of the accessor function normally supplied as the argument to the constructor? On 6/7/2013 4:51 PM, Tom Ellis wrote: > On Fri, Jun 07, 2013 at 04:05:0

[Haskell-cafe] Examples of MVars usage

2013-06-12 Thread Francisco M. Soares Nt.
Hello, everyone. I am looking for packages on hackage which use MVars extensively. Those which create plenty of MVars -- not just one or two for conditional synchronization or to keep track of a value throughout the program. My purpose is to analyze usage patterns of MVars. Does anybody have any s

[Haskell-cafe] Nightly builds of GHC HEAD for OS X 10.8

Since mid-January, I’ve been running nightly builds of GHC on my Mac Pro for 10.8.x, 64-bit. I’ve decided to make these results publically downloadable here: http://ghc.newartisans.com. The installer tarballs are in dist, while the fulltest and nofib logs are in logs. According to Jenkins thi

[Haskell-cafe] Testing invasive proposals with Hackager

2013-06-12 Thread Niklas Hambüchen
In many discussions we make guesses about how much code proposals like Functor => Monad would break. You can use https://github.com/dterei/Hackager to build all of Hackage (preferably in a VM). Of course many packages have external dependencies, so I'd like to share the following list of packages

First of all, thank you for your suggestions. You can try GitHub's code search For the moment I am ignoring Github because it's harder to separate stable development from unstable. Even so, it might be worth the trouble to check out github soon. Thank you, Lucas. Also take a look at Control.Con

My original problem was that I wanted to load a particular set of packages using 'cabal install'. It didn't work (cabal install issues) and while the maintainer reacted promptly and helpfully, cabal kept on trying to install the wrong version. Part of the problem was that blasting away ~/.cabal a
