`cabal configure` returns a non-zero exit code if something needs to be installed. Does that work as an alternative? Patrick On Tue, May 6, 2014 at 1:45 AM, Andrew Cowie <andrew@operationaldynamics.com

Is there a way to run e.g. `cabal install --only-dependencies` and have it return a non-zero exit code if, for instance, there IS something to do?
I tried `--dry-run` but the exit code is still 0 if something is missing.
[or have it return non-zero if there isn't work to do, or...]
