This package works as a prelude replacement for Haskell, providing more functionality and types out of the box than the standard prelude (such as common data types like ByteString and Text), as well as removing common ``gotchas'', like partial functions and lazy I/O. The guiding principle here is:

• If something is safe to use in general and has no expected naming conflicts, expose it.

• If something should not always be used, or has naming conflicts, expose it from another module in the hierarchy.

This library provides opaque unique identifiers in primitive state monads and a GADT-like type using them as witnesses of type equality.

This package attempts to provide support for using Amazon Web Services like S3 (storage), SQS (queuing) and others to Haskell programmers. The ultimate goal is to support all Amazon Web Services.

The mockery package provides support functions for automated testing.

This package converts between bytestrings and their hexadecimal string representation.

This package provides a regular expression toolkit for regex-base with compile-time checking of regular expression syntax, data types for matches and captures, a text replacement toolkit, portable options, high-level AWK-like tools for building text processing apps, regular expression macros with parsers and test bench, comprehensive documentation, tutorials and copious examples.

This library provides a datatype which can be interpreted by apply-refact. It exists as a separate library so that applications can specify refactorings without depending on GHC.

This module defines the Pandoc data structure, which is used by pandoc to represent structured documents. It also provides functions for building up, manipulating and serialising Pandoc structures.

Haskeline provides a user interface for line input in command-line programs. This library is similar in purpose to readline, but since it is written in Haskell it is (hopefully) more easily used in other Haskell programs.

Haskeline runs both on POSIX-compatible systems and on Windows.

Implementation of bidirectional TOML serialization.

This package provides a Readable type class for reading data types from ByteString and Text. It also includes efficient implementations for common data types.

This library provides wrappers around Prelude and Data.List functions, such as head and !!, that can throw exceptions.

ghc-citeproc parses Citation Style Language style files and uses them to generate a list of formatted citations and bibliography entries. For more information about CSL, see https://citationstyles.org/.

This package contains a wrapped name module for TimeLocale.

Haddock is a documentation-generation tool for Haskell libraries.

This package provides optimized functions to determine the edit distances for fuzzy matching, including Levenshtein and restricted Damerau-Levenshtein algorithms.

This package provides Haskell bindings to your system's native wcwidth and a command line tool to examine the widths assigned by it. The command line tool can compile a width table to Haskell code that assigns widths to the Char type.

This package provides a writer monad for multi-line string literals.

This package provides a simple interface for building .dot graph files, for input into the dot and graphviz tools. It includes a monadic interface for building graphs.

This package provides a simple logging abstraction that allows multiple back-ends.

Provides Arbitrary instances for fgl graphs to avoid adding a QuickCheck dependency for fgl whilst still making the instances available to others. Also available are non-fgl-specific functions for generating graph-like data structures.

This package provides a data type for colours and transparency. Colours can be blended and composed. Various colour spaces are supported. A module of colour names ("Data.Colour.Names") is provided.

This library provides minimal Haskell binding to libxml2.
