This package contains the C sources of LPeg, as well as some tiny Haskell helper to load the package. . <http://www.inf.puc-rio.br/~roberto/lpeg/>

A binding to libffi, allowing C functions of types only known at runtime to be called from Haskell.

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.

This library provides Comonads for Haskell.

The module Data.CaseInsensitive provides the CI type constructor which can be parameterised by a string-like type like: String, ByteString, Text, etc. Comparisons of values of the resulting type will be insensitive to cases.

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 the core data types and functions for parsing Commonmark. The parser is fully Commonmark-compliant and passes the test suite. It is designed to be customizable and easily extensible. To customize the output, create an AST, or support a new output format, one need only define some new typeclass instances. It is also easy to add new syntax elements or modify existing ones.

Accurate information about source positions is available for all block and inline elements. Thus the library can be used to create an accurate syntax highlighter or an editor with live preview. The parser has been designed for robust performance even in pathological cases that tend to cause stack overflows or exponential slowdowns in other parsers, with parsing speed that varies linearly with input length.

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 provides profunctors for Haskell.

This package provides a compatibility layer for using GHC call stacks with different versions of the compiler.

This package provides Haskell bindings to SDL2_ttf C++ library.

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

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 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-server/example/greet.hs Here> is a runnable example, with comments, that defines a dummy API and implements a webserver that serves this API, using this package. . <https://github.com/haskell-servant/servant/blob/master/servant-server/CHANGELOG.md CHANGELOG>

A data-type like Either but with differing properties and type-class instances.

Library support is provided for this different representation, including lens-related functions for converting between each and abstracting over their similarities.

The Validation data type is isomorphic to Either, but has an instance of Applicative that accumulates on the error side. That is to say, if two (or more) errors are encountered, they are appended using a Semigroup operation.

As a consequence of this Applicative instance, there is no corresponding Bind or Monad instance. Validation is an example of, "An applicative functor that is not a monad."

This library provides minimal Haskell binding to libxml2.

This package provides automatic formatting for Haskell files. Both a library and an executable.

This Haskell library provides pointed and copointed data types.

This package attempts to provide support for using Amazon Web Services like S3 (storage), SQS (queuing) and others to Haskell programmers. The ultimate goal is to support all Amazon Web Services.

Haskell-Source with Extensions (HSE, haskell-src-exts) is an extension of the standard haskell-src package, and handles most registered syntactic extensions to Haskell. All extensions implemented in GHC are supported. Apart from these standard extensions, it also handles regular patterns as per the HaRP extension as well as HSX-style embedded XML syntax.

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

This library provides a pure Haskell implementation of the Unicode Collation Algorithm described at http://www.unicode.org/reports/tr10/. It is not as fully-featured or as performant as text-icu, but it avoids a dependency on a large C library. Locale-specific tailorings are also provided.

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 package provides a functional library for creating efficient memo functions using tries.
