@hackage pretty-compact2.1

This package contains a pretty-printing library, a set of API's that provides a way to easily print out text in a consistent format of your choosing. This is useful for compilers and related tools.

This library produces more compact outputs than both Wadler-Leijen or Hughes-PJ algorithms, at the expense of computational ressources. The core API is based on Hughes-PJ, but some combinators of the Leijen API are implemented as well.
