Status update on sandboxed builds

Hi all, I thought I'd give everyone a status update on the sandboxed build support. Mikhail has been busy at work implementing automatic rebuilding of local dependencies. Local dependencies let you can build one unreleased package against another unreleased package, both residing in e.g. ~/src. This is similar to cabal-dev's add-source feature, but instead of installing a snapshot of a local package when the command is run we create a link to the package and rebuild it when needed. This means that you will be able to do something like this: cd proj cabal add-source ~/src/dep cabal build -- builds dep and then proj cabal build -- builds dep and then proj This will make it much easier working with collections of libraries. What remains to be done: * Implement the UI described here: http://hackage.haskell.org/trac/hackage/wiki/PackageEnvironments#Userinterfa... . This is mostly done already. We need to merge the current hidden cabal sandbox-* commands (e.g. cabal sandbox-build) into their standard variants (e.g. cabal build). * Lots of testing! Cheers, Johan
