#376: Allow constraint on using installed package versions ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: | ---------------------------------+------------------------------------------ We allow command line args for adding version constraints. Internally the dependency resolver can use constraints on the installed status. We should allow such constraints to be given on the command line, and possibly in the cabal config file. We should probably also allow preferences to be given on the command line too. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/376 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
