This library provides a wrapper to the Linux kernel's inotify feature, allowing applications to subscribe to notifications when a file is accessed or modified.

A rich drop-in replacement for base. For details and documentation please visit the project's home page.

This package implements a language similar to YAML or JSON but with fewer special cases and fewer dependencies. It emphasizes layout structure for sections and lists, and requires quotes around strings.

This package provides a data type for colours and transparency. Colours can be blended and composed. Various colour spaces are supported. A module of colour names ("Data.Colour.Names") is provided.

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 functions to prevent or capture writing to stdout and other handles.

This library provides functions to read, write and manipulate MIDI, WAVE and SoundFont2 multimedia files. It is written entirely in Haskell (without any FFI). It uses efficient parsing and building combinators for binary data stored in ByteStrings (based on the one in binary package).

This module allows tokens produced by skylighting-core to be rendered as ConTeXt commands.

This library provides implementations of concurrent FIFO queues (for both general boxed and primitive unboxed values) that are fast, perform well under contention, and offer a Chan-like interface. The library may be of limited usefulness outside of x86 architectures where the fetch-and-add instruction is not available.

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.

This package provides a basic random number generation library, including the ability to split random number generators.

This package provides functions for converting emoji names to emoji characters and vice versa.

How does it differ from the emoji package?

• It supports a fuller range of emojis, including all those supported by GitHub

• It supports lookup of emoji aliases from emoji

• It uses Text rather than String

• It has a lighter dependency footprint: in particular, it does not require aeson

• It does not require TemplateHaskell

This package provides IO operations from async package lifted to any instance of MonadBase or MonadBaseControl.

OpenGLRaw is a raw Haskell binding for the OpenGL 4.5 graphics system and lots of OpenGL extensions. It is basically a 1:1 mapping of OpenGL's C API, intended as a basis for a nicer interface. OpenGLRaw offers access to all necessary functions, tokens and types plus a general facility for loading extension entries. The module hierarchy closely mirrors the naming structure of the OpenGL extensions, making it easy to find the right module to import. All API entries are loaded dynamically, so no special C header files are needed for building this package. If an API entry is not found at runtime, a userError is thrown.

ghc-citeproc parses Citation Style Language style files and uses them to generate a list of formatted citations and bibliography entries. For more information about CSL, see https://citationstyles.org/.

This Haskell package provides an either monad transformer.

This library tries to call minimum system calls which are the bottleneck of web servers.

This package provides a small, efficient, and portable regex library for Perl 5 compatible regular expressions. The PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5.

Transformers provides functor and monad transformers, inspired by the paper "Functional Programming with Overloading and Higher-Order Polymorphism", by Mark P Jones, in Advanced School of Functional Programming, 1995 http://web.cecs.pdx.edu/~mpj/pubs/springschool.html.

This package contains:

• the monad transformer class (in Control.Monad.Trans.Class)

• concrete functor and monad transformers, each with associated operations and functions to lift operations associated with other transformers.

This package can be used on its own in portable Haskell code, in which case operations need to be manually lifted through transformer stacks (see Control.Monad.Trans.Class for some examples). Alternatively, it can be used with the non-portable monad classes in the mtl or monads-tf packages, which automatically lift operations introduced by monad transformers through other transformers.

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

This library provides Haskell bindings to the Zstandard compression algorithm, a fast lossless compression algorithm targeting real-time compression scenarios at zlib-level and better compression ratios.

Experimental Hspec support for testing WAI applications

This library provides core modules of a markup combinator library for Haskell.

Provides Arbitrary instances for fgl graphs to avoid adding a QuickCheck dependency for fgl whilst still making the instances available to others. Also available are non-fgl-specific functions for generating graph-like data structures.
