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.

Visualize live data structures in GHCi. Evaluation is not forced and you can interact with the visualized data structures. This allows seeing Haskell's lazy evaluation and sharing in action.

See https://dennis.felsing.org/ghc-vis/#basic-usage for the basic usage of ghc-vis or watch a short video demonstrating how it can be used with GHCi's debugger: https://dennis.felsing.org/ghc-vis/#combined-debugger
