#215: Overhaul support for package's tests ------------------------------+--------------------------------------------- Reporter: duncan | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: project(> week) | Ghcversion: 6.8.2 Platform: | ------------------------------+--------------------------------------------- The current support for running package's testsuites is almost uniformly unused and packages instead implement ad-hoc solutions which makes it hard for users to run the testsuites and impossible to automate on hackage. The current support is so trivial anyone who takes this task on can ignore it and start with a clean slate. A [http://www.haskell.org/pipermail/cabal-devel/2008-January/001661.html thread on the issue]. Here are some ideas for possible requirements: * Support tests even in the `Simple` build system. Do not require using the `build-type: Custom` just to be able to use tests. * Define a standard interface for returning test results from a testsuite to Cabal so they can be included into a build report and could be published on the hackage website or some other custom in-house test server. * Support for above interface in `QuickCheck` and `HUnit`. * Support for HPC when running testsuite programs, and gathering coverage results, again for reporting purposes. * We want to be able to run tests on a library that is not installed yet. This will rely on support in Cabal for registering a package inplace in a local package db, and building test code against that. * What about performance tests? What format should that use for reporting? The emphasis is on automation. A lot of interesting information becomes available with enough automation. For example we could compare on hackage which packages have more comprehensive testsuites (measured by HPC coverage). Or we could track performance over time. Once the data is available there is a lot we could do with it. It's not just for a public hackage server, developers could use this privately too. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/215> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#207: Jumping to code every and anywhere: What about installing source files and a tag file along with haddock and lib files ? --------------------------+------------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: misc | Version: HEAD Severity: normal | Keywords: tags source tagfile Difficulty: normal | Ghcversion: 6.8.2 Platform: | --------------------------+------------------------------------------------- == Introduction == I personally depend on tags because the source code only tells what is really going on. So it would be incredible useful to not only get information using ghci after loading libs but also beeing able to jump to all functions you might be using anywhere (The only solution providing this in all cases is uning tags, right? Because cpp defines can introduce new functions.. To be able to jump to the code source must be installed along with libs (the way you can optionally install haddock docs) == Use case: == setup configure --with-tags --install-source (or something like that) setup build && setup install do this for each dependency given in the .cabal file (VIM:) let tags+=system('ghc-pkg --query-tagfile-location haskell98-1.0.0.0') == Issues: == * Which tool to generate tag files? * ghc(i) when targeting ghc * the hasktags program shipping with ghc * some others? * Tagfile path type relative or absolute? * absolute: After moving/ installing the sources the tagfile must be patched * relative: Do editors take the right base directory to find source files? * When to invoke the tagfile generating program? * Perfect case would be after all preprocessing has been done (Thus the tagging program should understand line number changing comments!) * Template Haskell? ( This is really tricky I think ) * Hmm sorted tagfiles would be useful as well :) == alternatives ? == If you do not think this is useful (mandatory?) how do you lookup code? (Yes I know hoogle :) perhaps using Eclipse or Visual Studio? I'd like to start implementing this somehow the next weeks. So don't hesitate and start discussing Marc Weber -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/207> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

It would be nice to have this built into the 'cabal' program itself so that "cabal create" or "cabal init" or similar would interactively create a cabal package. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/171> 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

#185: Temporary executables leave foo.exe.manifest files behind ----------------------+----------------------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal | Version: HEAD Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.1 Platform: Windows | ----------------------+----------------------------------------------------- When Cabal creates and runs a temporary program, as it appears to do with hsc when running over the base libraries doing haddock, it leaves a manifest behind in dist. On Windows, ghc --make with 6.8.1 produces a foo.exe and a foo.exe.manifest. Cabal deletes the former, but not the latter. Very minor, but should be easy to fix too. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/185> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #188: file extensions

#188: file extensions --------------------------+------------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal | Version: 1.2.2.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.1 Platform: Linux | --------------------------+------------------------------------------------- GHC ignores Objective C sources unless -x c is passed to it on the command line before the source files. As far as I could tell there is no way to pass that option to GHC through Cabal so no .m files ever get built (well.. not completely true - setting ghc-options works but that breaks compilation of Haskell code). One way to get this to work would be to just add some extra code in Cabal to automatically pass -x c for .m files. This is probably a bad idea as someone might want or need to compile files using some other extension at some point. Another option is add some way of specifying compile options on a per-file (or group of files) basis: setting ghc-options to -x c just for one set of files. Still very limited but it's an improvement over the first option. Third option I can think of is to add a way of specifying compiler/extension pairs in Cabal so given compilers are automatically used to compile files with corresponding extensions. Depending on how much time I have I might look into adding this functionality myself but would like some feedback on which approach to take. Otherwise I might have to stick with autotools and ignore Cabal until it gets a bit more mature and flexible. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/188> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#189: Handle framework paths (-F) in Cabal --------------------------+------------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal | Version: 1.2.2.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.1 Platform: Mac OS | --------------------------+------------------------------------------------- There's been some discussion on the GHC trac ([http://hackage.haskell.org/trac/ghc/ticket/1931 1931], [http://hackage.haskell.org/trac/ghc/ticket/1798 1798], [http://hackage.haskell.org/trac/ghc/ticket/1395 1395]) about adding framework search paths (gcc's `-F` flag, and ghc's `-framework-path` flag). Currently Cabal handles `-framework`, but not `-framework-path`. I propose the following behavior for Cabal: 1. Add a `framework-path:` field which will pass `-framework-path` to `ghc` and `-F` to `gcc`, `hsc2hs`, et. al. 2. Always add `-F$HOME/Library/Frameworks` as an argument to the above programs (regardless of any `framework-path` entries). I believe `#1` to be uncontroversial. My reasoning for `#2` is the following: - `$HOME/Library/Frameworks` is the standard location to put frameworks if you do not have administrative access. - Without it, `readline.cabal` (e.g.) would need {{{ framework-path: /Users/judah/Library/Frameworks }}} which is not portable between machines. Finally, note that these flags only affect build behavior, not runtime loading of libraries (which searches `$HOME/Library/Frameworks` by default). See [http://hackage.haskell.org/trac/ghc/wiki/OSXFrameworks OSXFrameworks] for more info. -Judah -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/189> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
