#277: add data-dir field ------------------------------+--------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: HEAD Severity: minor | Keywords: Difficulty: easy (<4 hours) | Ghcversion: 6.8.2 Platform: | ------------------------------+--------------------------------------------- Cabal currently looks for data files to install relative to the source directory, giving the package author no possibility to move them into their own directory without cluttering up the cabal file (you end up writing things like {{{data-files: data/foo, data/bar, data/foobar}}}) and the source (where you'll have to include the {{{"data/"}}} prefix in all calls to {{{getDataFileName}}}). The proposal is to add a {{{data-dir}}} field to the package configuration that specifies a single path which is used as a prefix for all data files in the source directory. The location of the installed files is not affected by {{{data-dir}}}. Notes: * It's impossible to change {{{data-dir}}} to take a list of paths without breaking the {{{Paths_foo}}} module interface. * installation of data files will have to copy source files from a different location, ditto for sdist * installed packages don't change. In particular the {{{Paths_foo}}} module doesn't change. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/277 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
