[Hackage] #240: setup install does not preserve MacOS X resource forks

#240: setup install does not preserve MacOS X resource forks ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- I use the attached Setup.lhs file to do some Mac-related magic (which I unfortunately do not understand) on files built with wxhaskell on MacOS X. The key point about this magic is that it allows me to run a GUI from the command line. Without doing the magic, the GUI will open, but it will not react to any user interaction. I think the problem is that whatever mechanism we use to copy the binary over (say to /usr/local/bin) does not preserve the magic. That is, if I run it directly after a runhaskell Setup install, I get the non-reactive GUI. If I do a cp geni /usr/local/bin by hand, then the GUI reacts, presumably because on MacOS X cp also copies the magic over. Sorry for being so vague. Let me know if I can help in any way. -- Eric Kow -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/240> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #274: Add a 'build from sdist tarball' feature

#274: Add a 'build from sdist tarball' feature ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: low | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- I've often seen Darcs repos where the sdist tarball was incomplete, or where a person had a tarball which was incomplete. I think this is because most people just never use the tarball; if they do ever use it, it's because it's what was downloaded from Hackage. The reason is that doing so is much more complex than 'configure; build; install': you need to configure, create an sdist tarball, cd into dist/; do a tar -xvf or whatever of the correct tarball; cd into *that* - and then you can configure/build/install. Assuming it is a working tarball. Now, of course you can automate it. After the first dozen times, I wrote myself a shellscript to do all that for me: function build_sdist { clean_configure && sdist && cd dist/ && untar *.tar.gz && cd `ls -t ./ | grep "/" | head -n 1` && clean_configure && build && hinstall; haddock && hinstall; } (This is pretty long and imperfect, but it would be even longer if all the other aliases and function definitions were included; I think they're pretty straightforwardly named though, so I haven't included them.) It seems to me that this would be, at the very least, a useful adjunct to cabal check - if it makes sense to see whether various fields are filled out sanely, surely it makes sense to see whether needed files are included/listed? It might be even better to make the normal 'runhaskell Setup build' do it from sdist, but this is harder to code (besides the forgoing, you'd need to copy in the configuration from the top-level, from when the user ran 'runhaskell Setup configure' and added whatever options) and possibly more confusing ("But Foo.hs *is* there, right there in src/! Why can't Cabal find it?"). So I'd be satisfied to do something like 'cabal checkdist'. -- gwern -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/274> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #411: Command to install dependencies of a package.

#411: Command to install dependencies of a package. ---------------------------------+------------------------------------------ Reporter: mornfall | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: easy (<4 hours) | Ghcversion: 6.8.3 Platform: | ---------------------------------+------------------------------------------ Something like cabal install-deps or install --deps-only or such. We spoke about this with Duncan and this is the proposed solution to my use-case: I have a project that basically consists of a simple shebang haskell script (go.hs), which happens to have somewhat obscure dependencies. I am not interested in building a binary out of this script, nor installing it: but I'd like to use cabal to track and automatically install the dependencies for it. Hence, I would provide a cabal file, whose main purpose would be for people to run "cabal install-deps", which would enable them to run ./go.hs directly... Hopefully it is clear what I mean here... Don't hesitate to prod me if you have better suggestions, or, questions... -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/411> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

This could be part of GHC's installation script possibly, or maybe a feature of cabal install. cabal can check the installed packages for the previous version of GHC and "cabal install" them. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/199> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#330: Take non-haddock documentation in account ----------------------------+----------------------------------------------- Reporter: fons | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- The generation and installation of Non-Haddock documentation (README and INSTALL files, LaTeX and Docbook tutorials/guides, Haskell examples using the package in question) is not currently taken in account by Cabal. Making Cabal understand how to generate documentation for all those formats would probably be too ambitious, but it could be eased (e.g. letting the user provide Makefiles instead of creating custom hooks). More importantly, the installation of documentation would be much easier with a new package property such as "doc-files" ("data-files" nor "extra- source-files" are semantically suitable). -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/330> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#435: ban upwardly open version ranges in dependencies on base ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Cabal-1.8 Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: | ----------------------------+----------------------------------------------- This is wrong! {{{ build-depends: base }}} This is still wrong! {{{ build-depends: base >= 3 }}} Each major release of the base package breaks most packages. Packages should specify an upper bound on the base version. Eg: {{{ build-depends: base >= 3 && < 4 }}} or equivalently: {{{ build-depends: base == 3.* }}} Cabal should check for this and suggest a sensible upper version on the base package, given that we know that base follows the package version policy. Note this is a special case for base but in general we should do this for all packages that opt-in to the versioning policy (see #343). Doing it for all such packages is a medium term goal. Doing it for base is quick and easy and has a lot of immediate benefits for the next release of base. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/435> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
