#623: when a package is already installed, print the version as well ---------------------------------+------------------------------------------ Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ At the moment, when a package is already installed, '''cabal-install''' prints a message like the following: {{{

cabal install 'HaXml>1.3' Resolving dependencies... No packages to be installed. All the requested packages are already installed. If you want to reinstall anyway then use the --reinstall flag. }}}

It would be helpful to print the version(s) of the requested package(s) as well. One case where this would be useful is to help the user realise that a preferred-version entry is in effect - in the case above, the version of !HaXml selected would be 1.13.3, while the latest version on hackage is 1.20. The output could look like this: {{{

cabal install 'HaXml>1.3' Resolving dependencies... No packages to be installed. All the requested packages are already installed, in particular: HaXml-1.13.3 If you want to reinstall anyway then use the --reinstall flag. }}}
