This package contains a backend for ghc-persistent using the MySQL database server. Internally it uses the ghc-mysql-simple and mysql packages in order to access the database. This package supports only MySQL 5.1 and above. However, it has been tested only on MySQL 5.5. Only the InnoDB storage engine is officially supported.

This Haskell library provides a two-dimensional zipper data structure for editing text. The structure represents the body of text and an editing cursor which can be moved through it, along with a set of editing transformations.

Text zippers are generalized over the set of data types that might be used to store lists of characters (e.g., String, T.Text, etc.). Implementations using both of these examples are provided.

This library provides Haskell bindings for the OpenGL Utility Toolkit, a window system-independent toolkit for writing OpenGL programs.

The package provides mutable and immutable bit arrays.

This library provides tools to create command line interfaces with ease.

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.

This library provides convenient combinators for working with and building parsing combinator libraries. Given a few simple instances, you get access to a large number of canned definitions. Instances exist for the parsers provided by parsec, attoparsec and base's Text.Read.

This package provides low-level bindings to the zlib package.

This package defines a Language.Haskell.TH.Syntax.Compat module, which backports the Quote and Code types to work across a wide range of template-haskell versions. On recent versions of template-haskell (2.17.0.0 or later), this module simply re-exports Quote and Code from Language.Haskell.TH.Syntax.

Haskell has excellect handling of unicode, the Char type covers all unicode chars. Unfortunately, there's no possibility to read or write something to the outer world in an encoding other than ascii due to the lack of support for encodings. This library should help with that.

This package provides an abstraction for communicating with line-oriented network services while abstracting over the use of SOCKS5 and TLS (via OpenSSL)

This Haskell library provides utilities creating, comparing, parsing and printing Universally Unique Identifiers or UUIDs.

This package provides Haskell bindings to the X11 graphics library. The bindings are a direct translation of the C bindings.

This Haskell package supports the definition of generic functions. Datatypes are viewed in a uniform, structured way: the choice between constructors is represented using an n-ary sum, and the arguments of each constructor are represented using an n-ary product.

This package provides a plugin that allows you to set breakpoints for debugging purposes. See the [README](https://github.com/aaronallen8455/breakpoint#breakpoint) for details.

This package provides an interface to the directory package for users of path. It also implements some missing stuff like recursive scanning and copying of directories, working with temporary files/directories, and more.

This package profides a class for encoding and decoding UTF8 strings with instances for several common types. It also includes several functions for working with UTF8. It aims to be lightweight, depending only on Base and including only one module.

IP Routing Table is a tree of IP ranges to search one of them on the longest match base. It is a kind of TRIE with one way branching removed. Both IPv4 and IPv6 are supported.

This package provides a variety of alternative parser combinator libraries, including the original HuttonMeijer set. The Poly sets have features like good error reporting, arbitrary token type, running state, lazy parsing, and so on. Finally, Text.Parse is a proposed replacement for the standard Read class, for better deserialisation of Haskell values from Strings.

This package provides a pure interface for compressing and decompressing streams of data represented as lazy ByteStrings. It uses the zlib C library so it has high performance. It supports the zlib, gzip and raw compression formats. It provides a convenient high level API suitable for most tasks and for the few cases where more control is needed it provides access to the full zlib feature set.

This package provides a library for parsing and evaluating typst syntax. Typst (<https://typst.app>) is a document layout and formatting language. This library targets typst 0.13 and currently offers only partial support.

This package provides a mid-Level PostgreSQL client library, forked from ghc-mysql-simple.

This package contains a MonadRef type class that abstracts over the details of manipulating references, allowing one to write code that can operate in either the ST monad or the IO monad.

This is an implementation of Tarjan's Union-Find algorithm (Robert E.: Tarjan. "Efficiency of a Good But Not Linear Set Union Algorithm",JACM 22(2), 1975) in order to maintain an equivalence relation. This implementation is a port of the union-find package using the ST monad transformer (instead of the IO monad).
