This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
Debug.Diff is a quick tool for comparing two Haskell values, as
when diagnosing a test failure. It pretty-prints the values
(using the groom library) and passes them to an external diff
command (colordiff by default), which writes the diff to standard
output.
Debug.Diff.Config provides more control over the diff parameters.
