Re: [Haskell-cafe] Haskell Platform 2013.2.0.0 64bit.pkg
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 and ~/Library/Haskell wasn't enough: it's necessary to blast away ~/.ghc as well (which I had forgotten existed and of course never saw). * It would be handy if 'uninstall-hs' had an option, say * uninstall-hs --user * so that a user could in one step make it as if they had never * used the Haskell Platform. (Sigh. Changes to the GHC command line interface since 7.0 have broken one of the packages I used to have installed, and the maintainer's e-mail address doesn't work any more. And sometimes it seems as if every time I install anything with cabal something else breaks.) PS. Earlier today cabal gave me some confusing messages which turned out to mean 'GSL isn't installed'. Non-Haskell dependencies could be explained a little more clearly. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Re: [Haskell-cafe] Testing invasive proposals with Hackager
I was thinking about something similar some time ago, but not just testing but also fixing things automatically. Taking for example Semigroup = Monoid this would break in places where you have instance for Monoid but don't have instance for Semigroup. But if you have instance for Monoid making instance for Semigroup is straightforward: instance Semigroup TypeYouAreFixing where () = copy code from mappend for that type I'm still kind of new to Haskell, so I'm not sure how hard such, TemplateHaskell-like automagic migration tool, would be to make, but I feel like such a tool would be of incredible importance for the community. Because otherwise, without such thing, there are usually two ways a language can evolve: 1. Caring for backwards compatibility, and accumulating mistakes like that over time, and becoming more and more like crap. 2. Making fixes that break everyones code, and because of that being ignored by the industry. I like Haskell because it usually takes the second route, but as community grows it will be less and less the case. With such a tool you could have best of both worlds.
