ghc-blaze-textual is a fast Haskell library for rendering common Haskell datatypes in text form using the ghc-blaze-builder library.

Parsec is designed from scratch as an industrial-strength parser library. It is simple, safe, well documented (on the package homepage), has extensive libraries, good error messages, and is fast. It is defined as a monad transformer that can be stacked on arbitrary monads, and it is also parametric in the input stream type.

This package provides Unix terminal support for Vty.

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 is a Haskell library for writing CGI programs.

This library provides the ability to launch and interact with external processes. It wraps around the process library, and intends to improve upon it.

This library provides an implementation of the older blaze-builder interface in terms of the new builder that shipped with bytestring-0.10.4.0. This implementation is mostly intended as a bridge to the new builder, so that code that uses the old interface can interoperate with code that uses the new implementation.

This package provides the number parsers without the need to use a large (and unportable) token parser.

This package provides instances to push and receive any datatype encodable as JSON to and from the Lua stack.

Utilities to package up Haskell functions and values into a Lua module. . This package is part of HsLua, a Haskell framework built around the embeddable scripting language <https://lua.org Lua>.

This package implements the bijection between JSON and CBOR defined in the CBOR specification, RFC 7049.

This Haskell package provides interfaces and helper functions for the ghc-persistent package.

This library provides mechanisms to efficiently run periodic, on-demand actions in Haskell.

Haskell98 invariant functors (also known as exponential functors). For more information, see Edward Kmett's article Rotten Bananas.

This package implements selective applicative functors, which allow you to declare your effects statically, and select which to execute dynamically. See the paper on selective functors for more details.

C->Haskell assists in the development of Haskell bindings to C libraries. It extracts interface information from C header files and generates Haskell code with foreign imports and marshaling. Unlike writing foreign imports by hand (or using hsc2hs), this ensures that C functions are imported with the correct Haskell types.

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

The mockery package provides support functions for automated testing.

This library provides adjunctions and representable functors for Haskell.

Efficient hashing-based container types. The containers have been optimized for performance critical use, both in terms of large data quantities and high speed.

This package defines orphan instances that mimic instances available in later versions of base to a wider (older) range of compilers.

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.

Async provides a library to run IO operations asynchronously, and wait for their results. It is a higher-level interface over threads in Haskell, in which Async a is a concurrent thread that will eventually deliver a value of type a.

This Haskell library contains type definitions for Universally Unique Identifiers or UUIDs, and basic conversion functions.
