Zstandard compression packaged as a conduit. This is a very thin wrapper around the official hs-zstd interface.

SDL_image is an image file loading library. It loads images as SDL surfaces, and supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, TGA, TIFF, XCF, XPM, XV.

This package provides a Readable type class for reading data types from ByteString and Text. It also includes efficient implementations for common data types.

This package provides a simple (but internally ugly) memoization function.

This library is intended to be a comprehensive solution to parsing and selecting quality-indexed values in HTTP headers. It is capable of parsing both media types and language parameters from the Accept and Content header families, and can be extended to match against other accept headers as well. Selecting the appropriate header value is achieved by comparing a list of server options against the quality-indexed values supplied by the client. . In the following example, the Accept header is parsed and then matched against a list of server options to serve the appropriate media using mapAcceptMedia': . > getHeader >>= maybe send406Error sendResourceWith . mapAcceptMedia > [ ("text/html", asHtml) > , ("application/json", asJson) > ] . Similarly, the Content-Type header can be used to produce a parser for request bodies based on the given content type with mapContentMedia': . > getContentType >>= maybe send415Error readRequestBodyWith . mapContentMedia > [ ("application/json", parseJson) > , ("text/plain", parseText) > ] . The API is agnostic to your choice of server.

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

This package provides a family of combinators for defining webservices APIs and serving them . You can learn about the basics in the <http://docs.servant.dev/en/stable/tutorial/index.html tutorial>. . <https://github.com/haskell-servant/servant/blob/master/servant/CHANGELOG.md CHANGELOG>

This library provides tools for ensuring that class members are shared.

This package contains helper functions on top of Template Haskell.

For example, functionExtractor extracts all functions after a regexp-pattern, which can be useful if you wish to extract all functions beginning with test (for a test framework) or all functions beginning with wc (for a web service).

This package provides a Haskell wrapper over the LibYAML C library.

This module allows tokens produced by skylighting-core to be rendered as ANSI colored text.

This Haskell package provides the core MonadUnliftIO typeclass, a number of common instances, and a collection of common functions working with it.

This package provides a Conduit interface for the LZMA compression algorithm used in the .xz file format.

This library contains scalable timer functions provided by a timer manager.

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

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

This package enables users to expand type synonyms in Template Haskell abstract syntax trees (ASTs).

This package provides an interface to file locking functionalities.

This package provides Type-level booleans.

To store passwords securely, they should be salted, then hashed with a slow hash function. This library uses PBKDF1-SHA256, and handles all the details. It uses the cryptohash package for speed; if you need a pure Haskell library, pwstore-purehaskell has the exact same API, but uses only pure Haskell. It is about 25 times slower than this package, but still quite usable.

Lets multiple threads and external processes concurrently output to the console, without it getting all garbled up.

Built on top of that is a way of defining multiple output regions, which are automatically laid out on the screen and can be individually updated by concurrent threads. Can be used for progress displays etc.

This Haskell library provides a Template Haskell deriver for unboxed vectors, given a pair of coercion functions to and from some existing type with an Unbox instance.

This library provides tools for reading and manipulating the .cabal file format. . Version 3.6 (unlike the following versions) is a dummy package that prevents module name clases between Cabal and Cabal-syntax if used together with a Cabal flag as described below. . In Cabal-3.7 this package was split off. To avoid module name clashes, you can add this to your .cabal file: . > flag Cabal-syntax > description: Use the new Cabal-syntax package > default: False > manual: False > > library > -- ... > if flag(Cabal-syntax) > build-depends: Cabal-syntax >= 3.7 > else > build-depends: Cabal < 3.7, Cabal-syntax < 3.7 . This will default to the older build, but will allow consumers to opt-in to the newer libraries by requiring Cabal or Cabal-syntax >= 3.7

This package provides bindings to the ALSA simple mixer API.
