I had an inadequate patch that was good enough for my experiments (http://osdir.com/ml/cabal-devel@haskell.org/2010-01/msg00029.html) but lack the familiarity with the cabal-install design necessary to implement it properly. Sadly, the patch no longer applies to cabal-install HEAD, and regardless, it would make things a lot easier if it Just Worked out of the box. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/697> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

I played around with passing `--package-db ../dist/package.conf.inplace` to `configure` when configuring `tests/suite.cabal` without success. A `tests/README` file would be very useful. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/693> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #676: bash-completion gets confused by alias for rm

#676: bash-completion gets confused by alias for rm ---------------------------------+------------------------------------------ Reporter: benmachine | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: minor | Keywords: Difficulty: unknown | Ghcversion: 6.12.1 Platform: Linux | ---------------------------------+------------------------------------------ I have an alias for rm defined so that it is by default verbose (alias rm='rm -v' in my bashrc). When I do cabal install has<tab> I get something like: [ben@euler ~]$ cabal install hasbash: bad substitution: no closing "`" in `/tmp/cabal_completion.tD2o8O' It turns out that rm is helpfully going: removed `/tmp/cabal_completion.hb1zbc' and then cabal is trying to use this as part of the completion command - choking on the ` because bash thinks it is part of a substitution. So rm should probably explicitly discard its stdout. While I was there I noticed that "cat" is used redundantly. There's nothing really wrong with this so that part of the patch can be cut I suppose, but I thought it was neater to use bash's input redirection explicitly. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/676> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #674: Findable extra documentation

#674: Findable extra documentation ----------------------------+----------------------------------------------- Reporter: jbapple | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.6.0.3 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- I have a cabal package that should include extra documentation in the distribution. This documentation should not be written in Haddock. 1. There should be a field for this analogous to data-files or extra- source-files. The former is too much: the files do not need to be accessed by any Haskell runtime. The latter is not enough: it does not store the extracted files on the system on which the package is installed. 2. There should be a way for humans to find these files without loading up a GHC runtime or using Unix's "find". I suggest "cabal list" also shows, for installed packages with extra data or documentation files installed, where these files can be found. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/674> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
