This library implements mid-level Haskell bindings to the MySQL mysqlclient client library. It is aimed at speed and ease of use.

Lua module wrapping Text.DocLayout.

This library provides peek and poke functions for network byte order.

This Haskell package provides an abstract interface to highly-parameterizable queues/deques.

Background: There exists a feature space for queues that extends between:

• Simple, single-ended, non-concurrent, bounded queues

• Double-ended, thread-safe, growable queues with important points in between (such as the queues used for work stealing).

This package includes an interface for Deques that allows the programmer to use a single API for all of the above, while using the type system to select an efficient implementation given the requirements (using type families).

This package also includes a simple reference implementation based on IORef and Data.Sequence.

Fixpoint types and recursion schemes. If you define your AST as fixpoint type, you get fold and unfold operations for free.

This package introduces a type for paths upholding useful invariants.

This package provides pure-Haskell utilities for dealing with XML with the conduit package.

This package provides a variety of alternative parser combinator libraries, including the original HuttonMeijer set. The Poly sets have features like good error reporting, arbitrary token type, running state, lazy parsing, and so on. Finally, Text.Parse is a proposed replacement for the standard Read class, for better deserialisation of Haskell values from Strings.

This package provides a plugin that allows you to set breakpoints for debugging purposes. See the [README](https://github.com/aaronallen8455/breakpoint#breakpoint) for details.

This package provides a plotting library for Haskell, using gnuplot for rendering.

This package provides a new data structure for accurate on-line accumulation of rank-based statistics such as quantiles and trimmed means. . See original paper: "Computing extremely accurate quantiles using t-digest" by Ted Dunning and Otmar Ertl for more details <https://github.com/tdunning/t-digest/blob/07b8f2ca2be8d0a9f04df2feadad5ddc1bb73c88/docs/t-digest-paper/histo.pdf>.

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 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 clone of wl-pprint for use with the text library.

This package provides a simple interface for building .dot graph files, for input into the dot and graphviz tools. It includes a monadic interface for building graphs.

A nonce is an arbitrary number used only once in a cryptographic communication. This package contain helper functions for generating nonces. There are many kinds of nonces used in different situations. It's not guaranteed that by using the nonces from this package you won't have any security issues. Please make sure that the nonces generated via this package are usable on your design.

A parser and renderer for binary Olson timezone files whose format is specified by the tzfile(5) man page on Unix-like systems. For more information about this format, see http://www.iana.org/time-zones/repository/tz-link.html. Functions are provided for converting the parsed data into TimeZoneSeries objects from the timezone-series package.

Uniplate is a library for writing simple and concise generic operations. Uniplate has similar goals to the original Scrap Your Boilerplate work, but is substantially simpler and faster.

Highlighting-kate is a syntax highlighting library with support for nearly one hundred languages. The syntax parsers are automatically generated from Kate syntax descriptions, so any syntax supported by Kate can be added. An (optional) command-line program is provided, along with a utility for generating new parsers from Kate XML syntax descriptions.

This package defines new symbols for a number of functions, operators and types in the base package. All symbols are documented with their actual definition and information regarding their Unicode code point. They should be completely interchangeable with their definitions. For further Unicode goodness you can enable the UnicodeSyntax language extension. This extension enables Unicode characters to be used to stand for certain ASCII character sequences, i.e. → instead of ->, ∀ instead of forall and many others.

This package provides a drop-in replacement for the standard filepath library, operating on RawFilePath values rather than FilePath values to get the speed benefits of using ByteStrings.

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

This package provides instances for QuickCheck's \"Arbitrary\" typeclass.

This package provides Haskell bindings to the SDL2_gfx graphics library.
