data-tree-print

Print Data instances as a nested tree.

Provides functionality similar to that of the Show class: Taking some arbitrary value and returning a String.

• Output is not intended to be valid haskell.

• Requires a Data.Data.Data instance instead of a Text.Show one.

• Output, if large, is often easier to parse than show output due to the formatting as a nested tree.

• The user can adapt the behaviour at runtime using custom layouting expressed via syb-style extension.
