This package provides memory abstractions, such as chunk of memory, polymorphic byte array management and manipulation functions. It contains a polymorphic byte array abstraction and functions similar to strict ByteString, different type of byte array abstraction, raw memory IO operations (memory set, memory copy, ..) and more

Pattern synonyms for ASCII characters, e.g. . @ pattern SPACE :: Word8 pattern SPACE = 0x20 @.

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 small cross-platform library for reading and modifying the system clipboard. It uses xclip or xsel at runtime.

This library provides the POSIX regex backend used by the Haskell library regex-base.

This package exports a module which is the recommended starting point for using microlens if you aren't trying to keep your dependencies minimal. By importing Lens.Micro.Platform you get all functions and instances from microlens, microlens-th, microlens-mtl, microlens-ghc, as well as instances for Vector, Text, and HashMap. The minor and major versions of microlens-platform are incremented whenever the minor and major versions of any other microlens package are incremented, so you can depend on the exact version of microlens-platform without specifying the version of microlens you need. This package is a part of the microlens family; see the readme on Github.

This is a Haskell module for PortMidi audio library, which supports real-time MIDI input and output.

This package provides datatypes to construct Free monads, Free monad transformers, and useful instances. In addition it provides the constructs to avoid quadratic complexity of left associative bind, as explained in:

• Janis Voigtlander, Asymptotic Improvement of Computations over Free Monads, MPC'08

Chell is a simple and intuitive library for automated testing. It natively supports assertion-based testing, and can use companion libraries such as chell-quickcheck to support more complex testing strategies.

The conduit package is a solution to the streaming data problem, allowing for production, transformation, and consumption of streams of data in constant memory. It is an alternative to lazy I/O which guarantees deterministic resource handling, and fits in the same general solution space as enumerator/iteratee and pipes.

This is a small library for working with changes to JSON documents. It includes a library and two command-line executables in the style of the diff and patch commands available on many systems.

This library implements the GHC API. It is like the compiler-provided ghc package, but it can be loaded on many compiler versions.

This package provides a quasi-quoter for raw SQL for ghc-persistent.

Diagrams is a flexible, extensible embedded domain-specific language (EDSL) for creating graphics of many types. Graphics can be created in arbitrary vector spaces and rendered with multiple backends. This package provides a standard library of primitives and operations for creating diagrams.

This package provides fast unicode character sets for Haskell, based on complemented PATRICIA tries.

This package provides a custom prelude with no dependencies apart from the base package.

Foundation has the following goals:

1. provide a base like sets of modules that provide a consistent set of features and bugfixes across multiple versions of GHC (unlike base).

2. provide a better and more efficient prelude than base's prelude.

3. be self-sufficient: no external dependencies apart from base;

4. provide better data-types: packed unicode string by default, arrays;

5. Numerical classes that better represent mathematical things (no more all-in-one Num);

6. I/O system with less lazy IO.

This package provides Haskell bindings to SDL2_image.

This package provides a pure interface for compressing and decompressing LZMA streams of data represented as lazy ByteStrings. A monadic incremental interface is provided as well.

This library provides profunctors for Haskell.

This library provides a SOCKS proxy (version 5) implementation.

th-reify-many provides functions for recursively reifying top level declarations. The main intended use case is for enumerating the names of datatypes reachable from an initial datatype, and passing these names to some function which generates instances.

This package supplements the Validity typeclass with standard properties for functions operating on them.

Regex-tdfa is a pure Haskell regular expression library implementing POSIX extended regular expressions. It is a "tagged" DFA regex engine. It is inspired by libtre.

This package provides the following modules: Math.NumberTheory.Logarithms and Math.NumberTheory.Powers.Integer from the arithmoi package, GHC.Integer.Logarithms.Compat and Math.NumberTheory.Power.Natural, as well as some additional functions in migrated modules.
