#573: package page could mention used language extensions ----------------------------+----------------------------------------------- Reporter: explicitcall | Owner: Type: enhancement | Status: new Priority: low | Milestone: Component: miscellaneous | Version: 1.6.0.1 Severity: minor | Keywords: Difficulty: normal | Ghcversion: Platform: | ----------------------------+----------------------------------------------- It would be very convenient to see what language extensions a given package uses at its own hackageDB page. This information could be gathered from LANGUAGE pragmas put in distinct files or from GHC's -X options specified in .cabal file. Complete list of used extensions gives a possibility to see how the package can be used, as it's common practice to choose library judging by such features as portability and usability. For example, new library users could see how they possibly could understand code and documentation, as usage of extensions requires some better knowledge of the language. At the same time, power users could seek appropriate libraries which integrate properly with the list of language extensions they already use. The list of used extensions could be produced by hackageDB scripts every time the package is uploaded to hackageDB, or it can be generated by `cabal sdist` when a source distribution file is generated. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/573 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
