Parse numeric literals from ByteStrings.

A binary serialization library, similar to binary, that introduces an isolate primitive for parser isolation, and labeled blocks for better error messages.

'Checkers' wraps up the expected properties associated with various standard type classes as QuickCheck properties. Also some morphism properties. It also provides arbitrary instances and generator combinators for common data types.

This library provides an easy way to define command line parsers. Most users will want to use the "System.Console.CmdArgs.Implicit" module, whose documentation contains an example. * System.Console.CmdArgs.Explicit provides a way to write command line parsers for both single mode programs (most programs) and multiple mode programs (e.g. darcs or cabal). Parsers are defined by constructing a data structure. * System.Console.CmdArgs.Implicit provides a way to concisely define command line parsers, up to three times shorter than getopt. These parsers are translated into the Explicit data type. * System.Console.CmdArgs.GetOpt provides a wrapper allowing compatiblity with existing getopt parsers, mapping to the Explicit data type.

convertible provides a typeclass with a single function that is designed to help convert between different types: numeric values, dates and times, and the like. The conversions perform bounds checking and return a pure Either value. This means that you need not remember which specific function performs the conversion you desire. Also included in the package are optional instances that provide conversion for various numeric and time types, as well as utilities for writing your own instances. Finally, there is a function that will raise an exception on bounds-checking violation, or return a bare value otherwise, implemented in terms of the safer function described above. Convertible is also used by HDBC 2.0 for handling marshalling of data to and from databases. Convertible is backed by an extensive test suite and passes tests on GHC and Hugs.

A class for types with a default value.

Combinators for building fast hashing functions. Includes hashing functions for all basic Haskell 98 types.

This module provides set and multiset operations on ordered lists.

Prettyprint and compare Data values. * Size limit for the output * Time limit for the computation * Escape exceptions * Do not escape unicode characters * Comparison: Highlight the first difference * Comparison: Yes, No or Maybe results

Formatting time is slow. This package provides mechanisms to cache formatted date.
