We have community.haskell.org doing the hosting and hackage.haskell.org doing the package distribution. cabal- install now works fairly well and cabal-upload/cabal-put has been integrated.

So `showFilePath` and `parseFilePathQ` are the two inverses that are used by many fields. {{{ parseFilePathQ = parseTokenQ parseTokenQ = parseReadS <++ munch1 (\x -> not (isSpace x) && x /= ',') }}} `parseReadS` is a parser that uses `Read`, which for a `String` of course means parsing an ordinary Haskell string in quotes with escapes etc. The alternative then, if it is not surrounded in quotes, is a token is a bunch of characters that is not a space or ','. " and \ would be interpreted as it, eg `foo"bar\"baz` would all be one token. So correspondingly, the only characters that would cause a problem when pretty printing are spaces and ',', in which case we should use the standard `show` for `String`. So for example this means that '\' in Windows paths does not need to be escaped unless you use `"C:\\Foo\Bar"` in Haskell string syntax. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/115#comment:1> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #190: extension ForeignFunctionInterface should imply -fvia-C for ghc

#190: extension ForeignFunctionInterface should imply -fvia-C for ghc --------------------------+------------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.1 Platform: Linux | --------------------------+------------------------------------------------- I think the recommended practice with ghc is for code that uses FFI to compile via C to get the benefit of checking against C headers. So using that extension should imply not just -fffi but -fvia-C for ghc. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/190> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

darcs patch: a start at implementing #210, enable access to X- extension fields
by Brent Yorgey 30 Jan '08

30 Jan '08

Hi all, This is a start at collecting X- extension fields into a parsed GenericPackageDescription and making them available through the API. I've added [(String,String)] fields to the PackageDescription and BuildInfo types, and updated the parseFields function to take an extra parameter which can optionally do something with unrecognized fields. To parse X- fields then simply requires passing a function which takes unrecognized fields starting with X- and prepends them to the list of name,value pairs in the new record fields. Everything compiles and seems to parse things without error. The only problem is that I am confused about exactly what happens to parsed BuildInfo records and how one would extract the X- fields from a GenericPackageDescription later. I know that the X-fields get parsed into PackageDescription records properly, because they now get printed out when printing out a PackageDescription; however, I've had no such luck getting that to happen with Library or Executable objects, so I'm unsure how to test to see if the parsing worked. Suggestions/comments/pointers/patches appreciated! Note that this patch should NOT be applied in its current state! In particular it definitely breaks the property specified in #155. I'm seeking advice on how to get it to a place where it can safely be applied. thanks, -Brent

darcs patch : Add --program-prefix and --program-suffix options to configure (#208)
by Peter Higley 29 Jan '08

29 Jan '08

Attached is a patch that should resolve ticket #208. I wanted to "contribute" to Haskell in some way and an easy task seemed like a good place to start. I would have spoke up about my intent, but I wasn't sure how easy an "Easy Ticket" was. Yep, they're pretty easy! I have just joined the cabal-devel list, so if you have comments on the code feel free to speak up. Peter
