Name: type-level-natural-number Version: 2.0 License: BSD3 License-file: LICENSE Author: Gregory Crosswhite Maintainer: Gregory Crosswhite Stability: Provisional Synopsis: Simple type level natural numbers Description: This is a simple implementation of type-level natural numbers that only requires DeriveDataTypeable. Operations requiring more language extensions have been split into a separate package. . The difference between this package and the many others on Hackage implementing type-level naturals is its emphasis on simplicity. It only supports non-negative natural numbers, and only the successor and predicessor operations. It represents natural numbers using a type-level linked list, so it is not intended to be used for representing large numbers. Pre-defined aliases for natural numbers up to 15 are provided. . The code for this package was largely taken from the excellent Vec package; I created this package with the intent of making this functionality more widely available. . Difference from 1.0: Added instances for Typeable, and word synonyms for N0...N15. . Difference from 1.1: Performance enhancements for naturalNumberAsInt. Simplified Show implementation. . Difference from 1.1.1: Gave up on Haskell 2010 compatibility since as of GHC 7.8 manually deriving from Typeable is no longer allowed; now I use DeriveDataTypeable to construct the instances.
