Sounds OK if someone wants to do it, but I don't think it should be a high priority... I'd rather see support for stuff like this built into HackageDB. I really want to have a stable, testing, and unstable sections in Hackage where testing and stable have packages that are known to work (or at least build) together. peace, isaac ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

[Haskell-cafe] cabal specify a tested version, ghci target?
1.) I know I can use Build-Depends: lib == version, lib2 version, lib3 = version and so on. Do you think it would be useful to introducue some notation to indicate a tested with ? Reason, purpose: I think its sometimes the case that a author/ mantainer is quite busy with other projects and misses that some dependencies break things..

Cabal might then give a warning if you try to use 1.4 or greater using newer version than tested or similar.. What do you think? Would this be useful? 2.) Is there a ghci target? I find it quite useful using ghci to debug test/ check types functions of single modules... My hack is using a Setup.hs file like this adding ./setup ghci which runs ghci and adds all dependency as -pakcage arguments: module Main where import Distribution.Simple import Distribution.Simple.Configure import System import System.Process import System.Exit import Monad main= do args - getArgs -- check args to launch ghci when (length args 0) $ do when ((args!!0) == ghci) $ do lbi - getPersistBuildConfig let packageArgs = (concat.concat) [ [ -package , showPackageId pkg] | pkg - packageDeps lbi ] system(ghci ++ packageArgs) exitWith ExitSuccess defaultMain -- fallback to defaultMain Would this be useful for you, too?
