#883: Single command to figure out ghc[i] options needed to compile a single file ---------------------------------+------------------------------------------ Reporter: barsoap | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ I'm thinking of a {{{cabal options <file.hs>}}} command that 1. locates the proper .cabal file for <file.hs> 2. parses that .cabal 3. outputs all options necessary to compile that file as cabal build would do it, that is, {{{-isrc -idist/build/autogen (-Xwhatever)* -hide-all- packages (-package-id whatever)*}}} There's already cabal-ghci on hackage which has one half of the equation, but packages are missing. (which happen to be available via grep and sed from cabal_macros.h...) Needing those options comes up when e.g. working with vim's haskellmode on a cabal project: Most if not all cabal projects' files just fail to compile with default options. Having such a command would give a bullet- proof, non-hackish and low-tech way to integrate cabal with any such IDE tool. (Do note that just building with cabal isn't enough, while haskellmode can parse the resulting warnings and errors, it doesn't stand a chance to figure out types, among other things, that way) -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/883> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #894: Add benchmark support

#894: Add benchmark support ----------------------------+----------------------------------------------- Reporter: tibbe | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- Today, a user needs to rely on external tools, such as Make, to build benchmarks associated with a package. This has a couple of issues: * It's hard to have both Make (which builds the benchmark) and Cabal (which builds the library) pick the same versions of package dependencies. This leads to compilation errors when the user installs or removes some packages from his/her system. * It's hard to accurately track what needs to be rebuilt when, forcing the user to rebuild more than necessary, which wastes time. Proposal: Add a new `.cabal` file section for benchmarks, modeled after the "test-suite" section. Usage: {{{ cabal configure --enable-benchmarks cabal build cabal bench # results are written to stdout }}} -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/894> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#667: Improve tools to manage ad-hoc package releases ------------------------------+--------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: miscellaneous | Version: Severity: normal | Keywords: Difficulty: project(> week) | Ghcversion: Platform: | ------------------------------+--------------------------------------------- Hackage is suited for major software releases by package maintainers. It is not suited to distributing betas, daily snapshots or random forks, or patches of existing releases. For example a user may have some patch or bugfix for a package that they need. It takes time for maintainers to review and integrate these. Sometimes maintainers have little time, or they disagree with a patch approach or quality. It is right that maintainers have control over what is released on hackage. However there is a need for decentralised, ad-hoc and short term releases. We do not want to encourage the pollution of the package namespace with lots of short-term forks. One solution is to let users post package forks on their own webspace. We would want to extend cabal so that people can run: {{{ cabal install http://code.haskell.org/~user/foo/foo-fork-to-fix- blah-1.0.1.tar.gz }}} This makes it very decentralised. We may want to add some feature to hackage package pages to link to third-party forks. In addition to hosting and installing single packages it would be useful to be able to publish package collections. Of course this is exactly what a hackage archive is. We should provide easy tools to make and manage hackage archives that can be hosted on dumb http file servers. Going one step further, the hackage index format should be extended to make it more RESTful by including links to tarballs rather than just assuming that tarballs are found relative to the index file using some fixed layout. This would allow people to publish indexes that span multiple servers. This gets close to the concept of a package "search path" promoted by the searchpath project (http://searchpath.org/) Additonally, an index should allow us to point to source control repos rather than just to release tarballs. This kind of index would be useful for nighly builds. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/667> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
