Testing utilities for the validity library Note: There are companion instance packages for this library:
-
Type-safe, multi-backend data serialization. Hackage documentation generation is not reliable. For up to date documentation, please see: http://www.stackage.org/package/persistent.
-
Globbing library A library for globbing: matching patterns against file paths.
-
A class for types with a default value (compatibility shim) This module re-exports the Default class from Data.Default, for compatibility with older code.
-
Nicer interface for reified information about data types This package normalizes variations in the interface for inspecting datatype information via Template Haskell so that packages and support a single, easier to use informational datatype while supporting many versions of Template Haskell.
-
Support for well-typed paths Support for well-typed paths.

Tools for working with derived `Show` instances and generic inspection of values. We provide a library and an executable for working with derived Show instances. By using the library, we can parse derived Show instances into a generic data structure. The ppsh tool uses the library to produce human-readable versions of Show instances, which can be quite handy for debugging Haskell programs. We can also render complex generic values into an interactive Html page, for easier examination.

Converting to/from HTTP API data like URL pieces, headers and query parameters. This package defines typeclasses used for converting Haskell data types to and from HTTP API data. Please see README.md

Fast, high quality pseudo random number generation This package contains code for generating high quality random numbers that follow either a uniform or normal distribution. The generated numbers are suitable for use in statistical applications. . The uniform PRNG uses Marsaglia's MWC256 (also known as MWC8222) multiply-with-carry generator, which has a period of 2^8222 and fares well in tests of randomness. It is also extremely fast, between 2 and 3 times faster than the Mersenne Twister. . Compared to the mersenne-random package, this package has a more convenient API, is faster, and supports more statistical distributions.
-
locale library This package provides the ability to adapt to locale conventions such as date and time formats.
