#697: Add "cabal build-dep" command ---------------------------------+------------------------------------------ Reporter: igloo | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: major | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ The [http://hackage.haskell.org/trac/ghc/wiki/HackageTesting hackage testing tool] needs a "cabal build-dep" command to work. 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

I tried changing my HDBC dependency to == 2.2.2 as well as >= 2.2.6, but still get the same error for version 2.2.5.

[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

[Hackage] #760: exclude all but latest documentation from search results

#760: exclude all but latest documentation from search results --------------------------------+------------------------------------------- Reporter: warren | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: hackageDB website | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | --------------------------------+------------------------------------------- When searching for haskell documentation on google, quite frequently the top search results are versions of the library documentation from the archives. For instance, when searching for Data.Vector, the top hit is version 0.5, whereas the latest is 0.7. Also, if the user selects the 0.7 version, it isn't obvious from the documentation that this version corresponds to the latest since it also appears in the archive (the url is http://hackage.haskell.org/packages/archive/vector/0.7/doc/html/Data- Vector.html). So I'm wondering if it might not make sense to exclude all but the latest haddock documentation from search results by augmenting the robots.txt file. It might also make sense to provide alternate urls to the latest versions of documents. E.g. Starting from the http://hackage.haskell.org/package/vector page (which is the latest version), and clicking on Data.Vector, one is taken to http://hackage.haskell.org/packages/archive/vector/0.7/doc/html/Data- Vector.html... but it might be better if this were http://hackage.haskell.org/packages/current/vector/doc/html/Data- Vector.html. This would allow for all files under /archive to be excluded. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/760> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #767: Highlighted source code on hackage.haskell.org mangles Unicode

#767: Highlighted source code on hackage.haskell.org mangles Unicode ----------------------------------+----------------------------------------- Reporter: andersk | Owner: Type: defect | Status: new Priority: normal | Milestone: HackageDB Component: hackageDB website | Version: Severity: normal | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: Platform: | ----------------------------------+----------------------------------------- On hackage.haskell.org, when you browse the source of a module that contains Unicode (e.g. [http://hackage.haskell.org/packages/archive/base- unicode-symbols/latest/doc/html/src/Data-Eq-Unicode.html Data.Eq.Unicode]), it is sent with a `Content-Type: text/html` header with no charset. There is a charset in the XML declaration `<?xml version="1.0" encoding="UTF-8"?>`, but that is ignored by Firefox because of the non-XML `Content-Type`. Therefore, the wrong encoding is detected and the Unicode symbols get mangled. Possible fixes include sending `Content-Type: text/html; charset=UTF-8`, or sending `Content-Type: application/xhtml+xml` so that the XML declaration is respected , or both (`Content-Type: application/xhtml+xml; charset=utf-8`), or adding equivalent `<meta http-equiv="Content-Type">` tags. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/767> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
