Problem with Server.Helpers
by edgar＠ymonad.com 31 Mar '09

Hi, I installed haskell-happstack-helpers from AUR and I'm having some problems with the function exactdir on Happstack.Server.Helpers. The problem is that I can load normally the module, but the type of exactdir function is: GHCi, version 6.10.1: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer ... linking ... done. Loading package base ... linking ... done. Prelude> :m +Happstack.Helpers Prelude Happstack.Helpers> :t exactdir exactdir :: (Monad m) => String -> happstack-server-0.2.1:Happstack.Server.SimpleHTTP.ServerPartT m a -> happstack-server-0.2.1:Happstack.Server.SimpleHTTP.ServerPartT m a And ghc doesn't recognize when I pass a ServerPartT m a to exactdir. Prelude Happstack.Helpers Happstack.Server> simpleHTTP nullConf $ exactdir "/about" $ ok "Hello" <interactive>:1:22: Couldn't match expected type `ServerPartT IO a' against inferred type `happstack-server-0.2.1:Happstack.Server.SimpleHTTP.ServerPartT m [Char]' In the second argument of `($)', namely `exactdir "/about" $ ok "Hello"' In the expression: simpleHTTP nullConf $ exactdir "/about" $ ok "Hello" In the definition of `it': it = simpleHTTP nullConf $ exactdir "/about" $ ok "Hello" But if I copy the source of exactdir (and spsIf too) to the file where I use simpleHTTP the type checks correctly. Any ideas? Edgar

haskell-terminfo is missing dependency on extensible-exceptions
by Peter Hercek 12 Mar '09

12 Mar '09

Hi, Terminfo depends on extensible-exceptions based on the cabal file but the dependency is not in the PKGBUILD file. If it is not appropriate to send a notice here about bugs which are already mentioned in the corresponding aur page (http://aur.archlinux.org/packages.php?ID=17634) then, please, let me know. Peter.

haskell documentation
by Don Stewart 02 Mar '09

02 Mar '09

Forwarded from haskell@ I'd prefer a single documentation bundle for everything ever built on hackage, rather than trying to get haddock to run on each build. ----- Forwarded message from Piyush P Kurur <ppk(a)cse.iitk.ac.in> ----- Date: Sun, 1 Mar 2009 11:55:06 +0530 From: Piyush P Kurur <ppk(a)cse.iitk.ac.in> To: haskell(a)haskell.org Subject: [Haskell] haskell documentation Hi, I am a Arch linux + GHC user. I found it difficult to download documentations for GHC and all the modules. The GHC site does not seem to have a single tar.gz file by which one could down load the entire documentation tree. Same problem for modules build via yaourt. Of course one could build it directly from the appropriate cabal package but is there an automatic way via pacman/yaourt for example ? Regards ppk _______________________________________________ Haskell mailing list Haskell(a)haskell.org http://www.haskell.org/mailman/listinfo/haskell ----- End forwarded message -----
