haddock-2.3.0 literate comments discarded from .lhs input
by Alistair Bayley 27 May '09

27 May '09

I have this test case for Haddock (2.3.0): -------------------------------------------------- | Module : Test.Haddock Copyright : (c) 2009 Alistair Bayley License : BSD-style Maintainer : alistair(a)abayley.org Stability : stable Portability : portable Test case for Haddock. > module Test.Haddock > ( > -- $named_block > Fail(..) > ) > where > data Fail = Fail | Succeed $named_block This is some hadock documentation. -------------------------------------------------- This fails with: [1 of 1] Compiling Test.Fail ( Test\Fail.hs, Test\Fail.o ) Test\Fail.hs:11:26: Can't make a derived instance of `Typeable Fail' (You need -XDeriveDataTypeable to derive an instance for this class) In the data type declaration for `Fail' If I manually unlit, then Haddock is happy: -------------------------------------------------- -- | -- Module : Test.Haddock2 -- Copyright : (c) 2009 Alistair Bayley -- License : BSD-style -- Maintainer : alistair(a)abayley.org -- Stability : stable -- Portability : portable -- -- Test case for Haddock. module Test.Haddock2 ( -- $named_block Fail(..) ) where data Fail = Fail | Succeed -- $named_block -- -- This is some hadock documentation. -------------------------------------------------- so it looks as though it's discarding the literate comments. Is this intended? I was under the impression that because it used the ghc parser, it could now properly handle .lhs input. Ona related note, we have a nice unlitter in cabal that would preserve these comments before invoking haddock. Is this still used with haddock2, or does it now assume haddock2 will do the right thing? Alistair

Working on a fix for ticket #89
by Stephen Blackheath [to cabal-devel] 25 May '09

25 May '09

All, I'm working on a fix for ticket #89 (http://hackage.haskell.org/trac/hackage/ticket/89) and I have a specific question for the list: ---- If I do this... build-depends: base Library build-depends: bytestring ...then when the library compiles, it will fail to find the Prelude (i.e. -package base doesn't get passed to ghc). Is there a reason why the global 'build-depends' doesn't add to all targets (i.e. all exes & libs)? That's what I would expect it to do, but that might be just me. Or more to the point, should this be fixed? ---- The code changes I'm working on also fix a couple of other things, so this is the complete list: - Ticket #89: Make it so the executable can depend on the library defined in the same package. If hs-source-dirs is used, you can avoid it compiling the .hs files multiple times. - Make it so build-depends: defined in a Library or Executable block affects only the build of those components, not all components as currently happens. For avoidance of package breakage, this behaviour only happens if you specify cabal-version: >= 1.7 (that is, versions less than 1.7 are entirely excluded). - Make a really simple unit test harness using the test-framework package, and add some test cases for the new behaviour. The idea is that we can gradually integrate existing tests (hunit & quickcheck) into it. - Make UnitTests compile (though hardly any of the tests pass). This patch is not yet tidy enough to submit, but it is complete enough to actually work for GHC. I would welcome any comments. Here it is (against HEAD): http://upcycle.it/~blackh/cabal/cabal-ticket-89-v3.patch Steve

[Hackage] #553: wish: Have "setup configure" unconditionally pass options like --prefix to user-supplied configure script.

#553: wish: Have "setup configure" unconditionally pass options like --prefix to user-supplied configure script. ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- Cabal's "setup configure" can be made to run a user-supplied configure script. When so instructed, it passes command line options like --prefix along to that configure script. However, if no --prefix is given by the user, no --prefix option is passed along to the configure script either. This means that such a configure script cannot actually do anything with the prefix unless it is willing to make assumptions about what the default prefix is when none is specified. It would be better if Cabal passed the configure script a --prefix option (and maybe others) regardless of whether the user specified one, so that the script always has the real prefix available. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/553> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
