Elm Pretty Printer

An Elm implementation of the pretty printing library described in Phil Wadler's paper "A Prettier Printer".

Combinators here allow you to specify how a tree gets turned into text (you can choose HTML with custom attributes, or a simple string). You can

• specify indentation with nest
• use group to specify that a subtree should be on one line if it fits in the given width, or should have newlines if it doesn't.

Documentation is currently lacking; see Example.elm (pictured above) for usage, or the Wadler paper for description of the combinators.

This needs some optimization — a node with 10 children is quite slow to render on window resize in the example!
