Consider the following use case: I have to ship a Haskell application as source, bundled with its dependencies and a script that can produce the binary on a machine without internet connectivity.
This situation is not that uncommon; one example is when you have build-bots which a more or less cut off from the internet (such as Ubuntu's launchpad buildfarm)
Is that possible with Stack or Cabal? Any pointers would be much appreciated.
Ideally I would like to build each dependency package individually. That way I could cache results per Haskell package and don't need to rebuild dependencies until they actually change.
This sounds like something I'd use cabal's filesystem-local repository feature[1] for, and it should be possible to specify such local repositories in your `cabal.config` or `cabal.project`[2] files to produce a self-contained source distribution. If you're interested in pursuing this approach or have any questions about it, let me know! [1]: http://cabal.readthedocs.io/en/latest/installing-packages.html#repository-sp...
