I am pleased to announce the release of two new libraries: boomerang
and web-routes-boomerang.

boomerang is a library for general purpose, invertible parsing and
pretty printing. It provides combinators which allow you to specify a
grammar once and automatically extract a parser and pretty-printer
from it. This library was refactored, with permission, from the Zwaluw
library created by Sjoerd Visscher and Martijn van Steenbergen.

web-route-boomerang provides glue code for using boomerang with
web-routes. web-routes is a framework-independent, type-safe, url
routing library.

p.s. boomerang is similar in purpose to the inveritble-syntax library:


The libraries take different approaches and are both worth considering.
