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>

Provides default instances for types from the dlist package.

This Haskell library provides a two-dimensional zipper data structure for editing text. The structure represents the body of text and an editing cursor which can be moved through it, along with a set of editing transformations.

Text zippers are generalized over the set of data types that might be used to store lists of characters (e.g., String, T.Text, etc.). Implementations using both of these examples are provided.

Takes an error-throwing expression and puts it back in the Maybe it belongs in.

Note that this suffers from the https://ghc.haskell.org/trac/ghc/ticket/5902. Buyer beware.

This package provides functionality for generalising the deriving mechanism in Haskell to arbitrary classes.

This package provides various primitive memory-related operations.

This library provides functions for control flow inside of monads with anaphoric variants on if and when and a C-like switch function.

Knowledge of GHC's installation directories.

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

This package includes Hakell modules providing various helper functions for Lists, Maybes, Tuples, Functions.

This package profides a class for encoding and decoding UTF8 strings with instances for several common types. It also includes several functions for working with UTF8. It aims to be lightweight, depending only on Base and including only one module.

The config-ini Haskell library exports some simple monadic functions to ease the parsing of .ini-style configuration files, and to write and update them in an efficient diff-minimal way. This means that if you parse a file, update a single field, and reserialize, that file should differ only in the field we changed and that's it: field order, comments, and incidental whitespace will remain unchanged. The library aims to produce human-readable error messages when things go wrong.

This Haskell package provides an either monad transformer.

A cross-platform library with functions for adjusting code pages on Windows. On all other operating systems, the library does nothing.

The texmath library provides functions to read and write TeX math, presentation MathML, and OMML (Office Math Markup Language, used in Microsoft Office). Support is also included for converting math formats to pandoc's native format (allowing conversion, via pandoc, to a variety of different markup formats). The TeX reader supports basic LaTeX and AMS extensions, and it can parse and apply LaTeX macros.

This library provides exception safe semaphores that can be used in place of QSem, QSemN, and SampleVar, all of which are not exception safe and can be broken by killThread.

This library provides parsers and printers for bencoded data. Bencode is the encoding used by the peer-to-peer file sharing system BitTorrent for storing and transmitting loosely structured data.

This package provides a simple network library for all your connection needs. It provides a very simple API to create sockets to a destination with the choice of SSL/TLS, and SOCKS.

This package provides a newtype wrapper with FromJSON/ToJSON instances customisable via a phantom type parameter. The instances can be rendered to the original type using DerivingVia.

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.

Provides a FilePath datatype and utility functions for operating on it. Unlike the filepath package, this package does not simply reuse String, increasing type safety.

This package provides bindings to the ALSA simple mixer API.

Text.Regex.Base provides the interface API for regex-posix, regex-pcre, regex-parsec, regex-tdfa, regex-dfa.

This library provides adjunctions and representable functors for Haskell.
