Thanks for all the hard work! If you see this in OSX (#1009) while installing cabal 1.18: *Warning: could not create a symlink in /Users/lemao/Library/Haskell/bin for * *cabal because the file exists there already but is not managed by cabal. You* *can create a symlink for this executable manually if you wish. The executable* *file has been installed at* */Users/user/Library/Haskell/ghc-7.6.3/lib/cabal-install-1.18.0/bin/cabal* You will need to manually remove the pre-existing 1.16 links in ~/Library/Haskell/bin before installing again.

Hi all,

On behalf of the cabal maintainers and contributors I'm proud to announce the Cabal (and cabal-install) 1.18.0 release. To install run

cabal update && cabal install Cabal-1.18.0 cabal-install-1.18.0

With 854 commits since the last release there are two many improvements and bug fixes to list them here, but two highlights are:

* Hermetic builds using sandboxes. This should reduce the number of "dependency hell" and broken package DB problems.

* GHCi support. It's now much easier to use ghci when developing your packages, especially if those packages require preprocessors (e.g. hsc2hs).

Here's how working on a package might look like using the new features:

# Only once: cabal sandbox init cabal install --only-dependencies --enable-tests # Configure, build, and run tests: cabal test # now implies configure and build # Play around with the code in GHCi: cabal repl

That's a great feature! How can I configure Cabal to start ghci with certain options? I like to enable more warnings. I could not find a documentation for the Cabal config file.
