This package provides efficient vector-based hashtable implementation similar to .NET Generic Dictionary implementation (at the time of 2015).

This package provides Haskell bindings to SDL2_mixer.

LeanCheck support for test-framework. This package can be used to incorporate LeanCheck tests into test-framework test suites.

This is only for use in developing libraries that should conform to the persistent interface, not for users of the persistent suite of database libraries.

Uniplate is a library for writing simple and concise generic operations. Uniplate has similar goals to the original Scrap Your Boilerplate work, but is substantially simpler and faster.

The solver component used in cabal-install command-line program.

This package provides a modular backend for rendering diagrams created with the diagrams embedded domain-specific language (EDSL) to Scalable Vector Graphics (SVG) files.

This library provides a continuation-based, backtracking, logic programming monad. An adaptation of the two-continuation implementation found in the paper "Backtracking, Interleaving, and Terminating Monad Transformers" available online.

This package provides a low-level networking interface.

This package provides Haskell 98 groups. A group is a monoid with invertibility.

GLURaw is a raw Haskell binding for the GLU 1.3 OpenGL utility library. It is basically a 1:1 mapping of GLU's C API, intended as a basis for a nicer interface.

This library provides a type-safe embedded domain specific language (EDSL) for SQL queries that works with SQL backends as provided by ghc-persistent. Its language closely resembles SQL, so you don't have to learn new concepts, just new syntax, and it's fairly easy to predict the generated SQL and optimize it for your backend.

This library provides monad morphism utilities, most commonly used for manipulating monad transformer stacks.

This Haskell library provides a simple purely functional circular list, or ring, data type: a circular data structure such that if you continue rotating the ring in either direction, you'll eventually return to the element you first observed.

This library provides bindings for the Dot language used by the Graphviz suite of programs for visualising graphs, as well as functions to call those programs. Main features of the graphviz library include:

1. Almost complete coverage of all Graphviz attributes and syntax

2. Support for specifying clusters

3. The ability to use a custom node type

4. Functions for running a Graphviz layout tool with all specified output types

5. Generate and parse Dot code with two options: strict and liberal

6. Functions to convert FGL graphs and other graph-like data structures

7. Round-trip support for passing an FGL graph through Graphviz to augment node and edge labels with positional information, etc.

The ListLike module provides a common interface to the various Haskell types that are list-like. Predefined interfaces include standard Haskell lists, Arrays, ByteStrings, and lazy ByteStrings. Custom types can easily be made ListLike instances as well.

ListLike also provides for String-like types, such as String and ByteString, for types that support input and output, and for types that can handle infinite lists.

This package provides a Haskell wrapper over the LibYAML C library.

Haddock is a documentation-generation tool for Haskell libraries.

This package provides the tldr command and a Haskell client library allowing users to update and view tldr pages from a shell. The tldr pages are a community effort to simplify the man pages with practical examples.

This package provides state variables, which are references in the IO monad, like IORefs or parts of the OpenGL state.

This library provides a conduit-based, streaming interface for extracting and creating tar files.

This package provides a parser for plain-text representations of tables. This package supports table headers, cells spanning multiple columns or rows, as well as a way to specify column alignments.

This package provides a simple library for processing command-line options. The library captures a common usage pattern of the GetOpt module form the standard library.

This package provides a fully compliant Haskell 98 lexer.
