Hi,

Bauerbill uses the package list located at the following address to construct a database of Hackage packages:

http://hackage.haskell.org/packages/archive/pkg-list.html

As I've understood the guidelines, all library packages include the "haskell-" prefix whereas stand-alone applications do not.

A user recently reported an error while trying to build Pandoc from Hackage using Bauerbill. The problem seems to be that the aforementioned list describes Pandoc only as "programs", which causes Bauerbill to regard it as a stand-alone app.* Cabal2arch, however, is able to correctly determine that it includes libraries and should thus be named "haskell-pandoc".

Can anyone on this list (Dons?) correct the package list?

What is the best way to detect that a package contains libraries? I haven't looked at cabal2arch's source code but presumably it gleans such information from the .cabal file. I could update Bauerbill to do the same but having a global list is much more useful when managing multiple packages. Is the Hackage package list not generally reliable for this purpose?

The policy cabal2arch uses is: isLibrary = isJust (library cabal) && map toLower (display name) `notElem` shouldNotBeLibraries That is, if the .cabal file contains a 'library' stanza, we treat it as a library, but with the following exceptions for *well known exectuables*: shouldNotBeLibraries :: [String] shouldNotBeLibraries = ["xmonad" ,"gitit" ,"l-seed" ,"hspresent" ,"haskell-platform" ,"xmonad-contrib" ,"lambdabot" ,"piet" ,"hsffig" ,"yi" ,"haddock" ,"hscolour" ,"line2pdf" ,"distract" ,"derive" ,"Hedi" ,"conjure" ,"clevercss" ,"cpphs" ,"backdropper" ,"darcs-beta" ,"gtk2hs" ,"darcs" ,"greencard" -- the pandoc package doesnt' ship haskell-pandoc -- ,"pandoc" ,"pugs-drift" ,"wol" ,"timepiece" ,"hledger" ,"hp2any-graph" ,"hp2any-manager" ] So people looking for, e.g. gitit, find it in the gitit package, even when it installs additional support libraries.
