Improve cabal.config handling #22

Closed mietek closed 9 years ago

mietek commented 10 years ago

Find the right solution for omitted constraints in a cabal.config, following #10.

This is likely to require calling cabal freeze whether a cabal.config exists or not.

mietek commented 9 years ago

The importance of cabal.config is now documented as part of the Halcyon user’s guide and the Haskell on Heroku user’s guide.

Automatically detecting omitted constraints is not possible with the current implementation of cabal-install. The underlying issue is now tracked as https://github.com/haskell/cabal/issues/2265.
