1. Add a new function {{{ reifyPackage :: String -- Package name -> String -- Version -> Q [Package] }}} which, given a package name/version returns all the installed packages with that name and version.
I'm a little worried that this will encourage the people who previously wrote things like {{{ pkg = "haskell-src-exts-" ++ VERSION_haskell_src_exts }}} to instead call {{{ [pkg] <- reifyPackage "haskell-src-exts" VERSION_haskell_src_exts }}} just hoping that the result is a single package version. I'm not up to speed on the context here, but would it be possible to also provide {{{ thisPackage :: Q Package -- or maybe just :: Package }}} that refers to the package currently being built? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10279#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
