I’m happy to announce the first release of the pp library! This library provides a lean alternative to the Format module of the standard library. It uses the same comcepts of boxes and break hints, however it defines its own algebra which some might find easier to work with and reason about. I personally do The final rendering is still done via a formatter which makes it easy to integrate
Pp in existing programs using
We introduced this module in Dune to help improve the formatting of messages printed in the terminal and it has been a success. The new API is smaller, simpler and makes it easy for developers to do the right thing. Once the
Pp module of Dune was mature enough, we decided to extract it into a separate library so that it could benefit others.
The library itself is composed of a single
Pp module and has no dependencies. Its documentation is self-contained and no previous knowledge is required to start using it, however the various guides for the
Format module such as this one should be applicable to
Pp as well.
If you have used
Format before and like me found its API complicated and difficult to use, I hope that you will find
Pp nicer to work with!
