This package provides low-level bindings to the zlib package.

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>

This library provides a fast parser combinator library, aimed particularly at dealing efficiently with network protocols and complicated text/binary file formats.

This package provides a type called @DMap@ which generalizes @Data.Map.Map@, allowing keys to specify the type of value that can be associated with them.

This package provides an implementation of the standard diff algorithm, and utilities for pretty printing.

ANSI terminal backend for the prettyprinter package.

This library provides extensible optionally-pure exceptions for Haskell.

This package provides Haskell bindings to the SDL2_gfx graphics library.

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.

Haskeline wrapper for GHCi-like REPL interfaces. Composable with normal mtl transformers.

This package provides Haskell bindings to your system's native wcwidth and a command line tool to examine the widths assigned by it. The command line tool can compile a width table to Haskell code that assigns widths to the Char type.

The PGP Word List consists of two phonetic alphabets, each with one word per possible byte value. A string of bytes is translated with these alphabets, alternating between them at each byte.

The PGP words corresponding to the bytes 5B 1D CA 6E are "erase breakaway spellbind headwaters", for example.

For further information, see http://en.wikipedia.org/wiki/PGP_word_list.

Cairo is a library to render high quality vector graphics. There exist various backends that allows rendering to Gtk windows, PDF, PS, PNG and SVG documents, amongst others.

This package provides an abstract class to manipulate sequence of bytes. The use case of this class is abstracting manipulation of types that are just wrapping a bytestring with stronger and more meaniful name.

Clear to write, read and edit Haskell DSL for HTML.

• Names are consistent, and do not conflict with base or are keywords (all have suffix -).

• Same combinator can be used for attributes and elements (e.g. style_).

This haskell library provides validity and validity-based testing for ghc-hspec.

This Haskell package supports the definition of generic functions. Datatypes are viewed in a uniform, structured way: the choice between constructors is represented using an n-ary sum, and the arguments of each constructor are represented using an n-ary product.

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 an implementation of n-ary sums and n-ary products. The module Data.SOP is the main module of this library and contains more detailed documentation. The main use case of this package is to serve as the core of generics-sop.

GHC 7.4 introduced a new casMutVar PrimOp which is difficult to use safely, because pointer equality is a highly unstable property in Haskell. This library provides a safer method based on the concept of Tickets.

This package works as a prelude replacement for Haskell, providing more functionality and types out of the box than the standard prelude (such as common data types like ByteString and Text), as well as removing common ``gotchas'', like partial functions and lazy I/O. The guiding principle here is:

• If something is safe to use in general and has no expected naming conflicts, expose it.

• If something should not always be used, or has naming conflicts, expose it from another module in the hierarchy.

This library provides typeclasses for rendering ghc-commonmark to Pandoc types.

This package provides a string interpolation library for Haskell.
