[Haskell-cafe] Wrong Package-URL in regex-tdfa.cabal
Hello. The cabal file for the regex-tddfa-1.1.6 package seems to have an invalid URL for the Package-URL field: Package-URL: http://darcs.haskell.org/packages/regex-unstable/regex-tdfa/ It should be fixed.

Re: [Haskell-cafe] Why does cabal unnecessarily reinstall dependencies?
It might be that it both your own package and the dependencies cabal tries to reinstall all depend on some package P. If the dependencies are installed depending on P version 1, but to satisfy all dependencies for your own package, cabal needs them to depend on P version 2, cabal will reinstall them (possibly breaking other packages that depend on them; is this a bug?) You can see if this is the case by running 'cabal install --dry-run -v'.

[Haskell-Cafe] VNC server in Haskell
Hi, I've implemented a VNC server (very incomplete) - What it can do currently is display a blue screen (100x100 screen). It's very trivial to try out - https://github.com/ckkashyap/Chitra I look forward to some feedback/comments on this. -- Regards, Kashyap ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] Re: Why does cabal unnecessarily reinstall dependencies?
I've noticed that ghc-6.10.4 did not work well with cabal-install version 0.8.2. (cabal install gtk did not work.) Everything was fine after I switched back to: cabal-install version 0.6.2 using version 1.6.0.3 of the Cabal library and removing the Cabal 1.8... library package.

Does anyone worked this out ? You can re-use your old cabal binary (if you still have it) that was compiled with ghc-6.

On 20/11/2010 08:42 AM, Tillmann Rendel wrote: Hi Andrew, Andrew Coppin wrote: Now, what about type variables? What do they do? Well now, that seems to be slightly interesting, since a type variable holds an entire type (whereas normal program variables just hold a single value), and each occurrance of the same variable is statically guaranteed to hold the same thing at all times. It's sort of like how every instance of a normal program variable holds the same value, except that you don't explicitly say what that value is; the compiler infers it. What do you mean by hold the same thing at all times? Consider the following program: id :: forall a . a - a id x = x call1 :: Bool call1 = id True call2 :: Int call2 = id 42 This program contains a type variable a, and a value variable x. Now, these variables do *not* mean the same thing at all times. In the first call of id, a is Bool and x is True; but in the second call of id, a is Int and x is 42. If these variables would mean the same thing at all times, I would expect them to be called constants, wouldn't you? That would be why I said instance of a variable, rather than variable.
