@hackage portray-prettyprinter0.2.1

This provides a prettyprinter backend for portray along with derivable Pretty instances for types with Portray instances.

This backend has largely superseded the original portray-pretty. Because prettyprinter gives more flexibility to documents at the cost of requiring more behavior to be specified explicitly, some formats are nicer with this backend, configurable syntax highlighting is supported, and unicode escaping is configurable. However, as this backend is still newer, there are potentially more unnoticed formatting bugs. Please do file bugs on the GitHub issue tracker if you find anything that seems obviously wrong!

Try using pp as the print function in GHCi: :set -interactive-print=Data.Portray.Prettyprinter.pp!
