This package turn Data.Serialize Gets and Puts into Sources, Sinks, and Conduits.

Utilities for dealing with IEEE floating point numbers, ported from the Tango math library; approximate and exact equality comparisons for general types.

In Haskell you very often acquire values using the with... idiom using functions of type (a -> IO r) -> IO r. This idiom forms a Monad, which is a special case of the ContT monad (from transformers) or the Codensity monad (from kan-extensions). The main purpose behind this package is to provide a restricted form of these monads specialized to this unusually common case.

The reason this package defines a specialized version of these types is to:

• be more beginner-friendly,

• simplify inferred types and error messages, and:

• provide some additional type class instances that would otherwise be orphan instances

This Haskell package provides Monomorphic variants of the Functor, Foldable, and Traversable typeclasses. If you understand Haskell's basic typeclasses, you understand mono-traversable. In addition to what you are used to, it adds on an IsSequence typeclass and has code for marking data structures as non-empty.

The options package lets library and application developers easily work with command-line options.

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.

This module provides set and multiset operations on ordered lists.

This package provides a library for generating 2D charts and plots, with backends provided by the Cairo and Diagrams libraries.

Language C is a Haskell library for the analysis and generation of C code. It features a complete, well-tested parser and pretty printer for all of C99 and a large set of GNU extensions.

Using the API Annotations available from GHC 7.10.2, this library provides a means to round-trip any code that can be compiled by GHC, currently excluding .lhs files.

This package provides distributive functors for Haskell. Dual to Traversable.

This package provides tools to measure the memory usage of a Haskell value or function.

Old-time is a package for backwards compatibility with the old time library. For new projects, the newer time library is recommended.

ResourceT is a monad transformer which creates a region of code where you can safely allocate resources.

This library lets you write interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse. Reflex is a fully-deterministic, higher-order FRP interface and an engine that efficiently implements that interface.

This package provides instances defined in later versions of ghc-binary package.

Derive instances of Arbitrary for QuickCheck, with various options to customize implementations.

Automating the arbitrary boilerplate also ensures that when a type changes to have more or fewer constructors, then the generator either fixes itself to generate that new case (when using the uniform distribution) or causes a compilation error so you remember to fix it (when using an explicit distribution).

This package also offers a simple (optional) strategy to ensure termination for recursive types: make Test.QuickCheck.Gen's size parameter decrease at every recursive call; when it reaches zero, sample directly from a trivially terminating generator given explicitly (genericArbitraryRec and withBaseCase) or implicitly (genericArbitrary').

This package provides ANSI terminal support for Haskell. It allows cursor movement, screen clearing, color output showing or hiding the cursor, and changing the title.

Alex is a tool for generating lexical analysers in Haskell. It takes a description of tokens based on regular expressions and generates a Haskell module containing code for scanning text efficiently. It is similar to the tool lex or flex for C/C++.

This library provides a fast parser combinator library, aimed particularly at dealing efficiently with network protocols and complicated text/binary file formats.

This Haskell library algorithms for vector arrays.

Clear to write, read and edit Haskell DSL for HTML.

• Names are consistent, and do not conflict with base or are keywords (all have suffix -).

• Same combinator can be used for attributes and elements (e.g. style_).

Cheapskate is an experimental Markdown processor in pure Haskell. It aims to process Markdown efficiently and in the most forgiving possible way. It is designed to deal with any input, including garbage, with linear performance. Output is sanitized by default for protection against cross-site scripting (XSS) attacks.

This package provides a data structure representing a bidirectional mapping between two key types. Each value in the bimap is associated with exactly one value of the opposite type.
