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 provides Haskell bindings to SDL2_mixer.

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
====++===========+===========++=============+============
A 1 ||       hog |  terrible ||        slow |      slower
A 2 ||       pig |   not bad ||        fast |     slowest
----++-----------+-----------++-------------+------------
B 1 ||      good |     awful || intolerable |    bearable
B 2 ||    better | no chance ||    crawling |     amazing
B 3 ||       meh |   well... ||  worst ever |          ok

This package provides ordered containers of intervals, with efficient search for all keys containing a point or overlapping an interval. See the example code on the home page for a quick introduction.

This package provides a wrapper around the Pango C library that allows high-quality rendering of Unicode text. It can be used either with Cairo to output text in PDF, PS or other documents or with Gtk+ to display text on-screen.

This package provides a Storable instance for pairs and triples which should be binary compatible with C99 and C++. The only purpose of this package is to provide a standard location for this instance so that other packages needing this instance can play nicely together.

This package provides portable implementations of parts of the unix package. This package re-exports the unix package when available. When it isn't available, portable implementations are used.

This package provides default instances for types from the base package.

This library provides tools for fast Unicode 12.1.0 normalization in Haskell (normalization forms C, KC, D, and KD).

This package provides a library and an executable for working with derived Show instances. By using the library, derived Show instances can be parsed into a generic data structure. The ppsh tool uses the library to produce human-readable versions of Show instances, which can be quite handy for debugging Haskell programs. We can also render complex generic values into an interactive Html page, for easier examination.

The doctest program checks examples in source code comments. It is modeled after doctest for Python (<https://docs.python.org/3/library/doctest.html>). . Documentation is at <https://github.com/martijnbastiaan/doctest-parallel#readme>.

The mockery package provides support functions for automated testing.

This library provides Haskell bindings for checking currently mounted filesystems.

This library provides Haskell bindings to the MySQL mysqlclient client library. It is a fairly faithful, low level library that implements most of the MySQL client API. The major departure from the C API is that in Haskell, resource management is mostly automatic and safe.

This library deliberately avoids the question of providing a ``good'' API. Its purpose is to serve as a base upon which higher-level libraries can be built.

The conduit package is a solution to the streaming data problem, allowing for production, transformation, and consumption of streams of data in constant memory. It is an alternative to lazy I/O which guarantees deterministic resource handling, and fits in the same general solution space as enumerator/iteratee and pipes.

Checkers wraps up the expected properties associated with various standard type classes as QuickCheck properties. It also provides some morphism properties, arbitrary instances, and generator combinators for common data types.

This library provides the Data.Primitive.Addr module that was a part of the primitive library before primitive-0.7.0.0.

th-reify-many provides functions for recursively reifying top level declarations. The main intended use case is for enumerating the names of datatypes reachable from an initial datatype, and passing these names to some function which generates instances.

This Haskell library provides utilities creating, comparing, parsing and printing Universally Unique Identifiers or UUIDs.

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."

SecureMem is similar to ByteString, except that it provides a memory chunk that will be auto-scrubbed after it run out of scope.

This package provides a string interpolation library for Haskell.

ByteString-backed Handles

This Haskell library provides a type class for the error function, erf, and related functions. Instances for Float and Double.
