IP Routing Table is a tree of IP ranges to search one of them on the longest match base. It is a kind of TRIE with one way branching removed. Both IPv4 and IPv6 are supported.

This package contains bindings to the SDL 2 library, in both high- and low-level forms. The SDL namespace contains high-level bindings, where enumerations are split into sum types, and we perform automatic error-checking. The SDL.Raw namespace contains an almost 1-1 translation of the C API into Haskell FFI calls. As such, this does not contain sum types nor error checking. Thus this namespace is suitable for building your own abstraction over SDL, but is not recommended for day-to-day programming.

This library provides a number of common functions and types useful in statistics. We focus on high performance, numerical robustness, and use of good algorithms. Where possible, we provide references to the statistical literature.

The library's facilities can be divided into four broad categories:

• Working with widely used discrete and continuous probability distributions. (There are dozens of exotic distributions in use; we focus on the most common.)

• Computing with sample data: quantile estimation, kernel density estimation, histograms, bootstrap methods, significance testing, and regression and autocorrelation analysis.

• Random variate generation under several different distributions.

• Common statistical tests for significant differences between samples.

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

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.

Lightweight pure data validation based on Applicative and Selective functors.

Haddock is a documentation-generation tool for Haskell libraries. These modules expose some functionality of it without pulling in the GHC dependency. Please note that the API is likely to change so specify upper bounds in your project if you can't release often. For interacting with Haddock itself, see the ‘haddock’ package.

This Haskell library provides a place for lots of orphan instances for the ghc-vector package.

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 tries to call minimum system calls which are the bottleneck of web servers.

GNU ncurses is a library for creating command-line application with pseudo-graphical interfaces. This package is a nice, modern binding to GNU ncurses.

This library provides Control.Lens. The combinators in Control.Lens provide a highly generic toolbox for composing families of getters, folds, isomorphisms, traversals, setters and lenses and their indexed variants.

This Haskell library provides simple read-only access to the local computer's networking configuration. It is currently capable of getting a list of all the network interfaces and their respective IPv4, IPv6 and MAC addresses.

This package implements selective applicative functors, which allow you to declare your effects statically, and select which to execute dynamically. See the paper on selective functors for more details.

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

This package provides a pretty printing class similar to Show, based on the HughesPJ pretty printing library. It provides the pretty printing class and instances for the Prelude types.

This package provides type classes, a monad and a monad transformer that support unchecked extensible exceptions as well as asynchronous exceptions. It is compatible with the transformers package.

This package provides a parser for plain-text representations of tables. This package supports table headers, cells spanning multiple columns or rows, as well as a way to specify column alignments.

Tabular provides a Haskell representation of two-dimensional data tables, the kind that you might find in a spreadsheet or or a research report. It also comes with some default rendering functions for turning those tables into ASCII art, simple text with an arbitrary delimiter, CSV, HTML or LaTeX.

Below is an example of the kind of output this library produces. The tabular package can group rows and columns, each group having one of three separators (no line, single line, double line) between its members.

    || memtest 1 | memtest 2 ||  time test  | time test 2

This package provides functions for converting emoji names to emoji characters and vice versa.

How does it differ from the emoji package?

• It supports a fuller range of emojis, including all those supported by GitHub

• It supports lookup of emoji aliases from emoji

• It uses Text rather than String

• It has a lighter dependency footprint: in particular, it does not require aeson

• It does not require TemplateHaskell

This package provides functions to marshal and unmarshal pandoc document types to and from Lua. . The values of most types are pushed to pandoc as "userdata" objects that wrap a stable pointer to the Haskell value; these objects come with methods to access and modify their properties. . Sequences are pushed as normal Lua tables, but are augmented with convenience functions.

When you've caught all the exceptions that can be handled safely, this is what you're left with.

This library provides some useful extensions for ghc-commonmark to parser core commonmark syntax: smart quotes, definition lists, tables, footnotes, math, and more.

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