This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

A library providing tools for building enumeration procedures for recursively- enumerable datatypes. This is built atop the arith-encode library, and makes use of the natural number isomorphisms it provides to represent individual decisions in the enumeration procedure. As such, each enumeration result is denoted by a unique path, consisting of a sequence of natural numbers. An enumeration procedure is simply a (partial) mapping between sequences and a given datatype.

The library provides functionality for constructing enumeration procedures, as well as facilities for performing enumeration according to various search strategies (depth-first, breadth-first, etc). These procedures can also be "warm-started" using a path or a set of paths. Obvious applications include exhaustive search, testing, automated proving, and others.

Additionally, as a path is simply a sequence of natural numbers, an enumeration procedure can double as a binary serializer/deserializer. For well-behaved enumeration procedures (ie. those where the mapping is an isomorphism), the resulting binary format should be very nearly succinct.

This is the first release candidate for 1.0 (initial release)
