This library provides an efficient implementation of Int-indexed arrays (both mutable and immutable), with a powerful loop optimisation framework.

This package provides several functions to quickly search for substrings in strict or lazy ByteStrings. It also provides functions for breaking or splitting on substrings and replacing all occurrences of a substring (the first in case of overlaps) with another.

This library provides a utility function liftType, which accepts a type application argument and returns the Template Haskell Type representation of it.

This package contains the C sources of LPeg, as well as some tiny Haskell helper to load the package. . <http://www.inf.puc-rio.br/~roberto/lpeg/>

This package contains basic definitions related to indexed profunctors. These are primarily intended as internal utilities to support the optics and generic-lens package families.

This package provides a minimal host for SDL2-based Reflex applications.

This package provides Haskell 98 groups. A group is a monoid with invertibility.

This library provides law-abiding lenses for Aeson, using microlens.

IWlib is a thin Haskell binding to the iw C library. It provides information about the current wireless network connections, and adapters on supported systems.

This package provides orphan instances for Template Haskell datatypes. In particular, instances for Ord and Lift, as well as a few missing Show and Eq instances. These instances used to live in the haskell-src-meta package, and that's where the version number started.

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

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.

This Haskell package provides compatibility layer for ghc-aeson.

Knowledge of GHC's installation directories.

Cheapskate is an experimental Markdown processor in pure Haskell. It aims to process Markdown efficiently and in the most forgiving possible way. It is designed to deal with any input, including garbage, with linear performance. Output is sanitized by default for protection against cross-site scripting (XSS) attacks.

This library provides minimal Haskell binding to libxml2.

Pandoc-server provides pandoc's document conversion functions in an HTTP server.

This package provides a data type These a b which can hold a value of either type or values of each type. This is usually thought of as an "inclusive or" type (contrasting Either a b as "exclusive or") or as an "outer join" type (contrasting (a, b) as "inner join").

data These a b = This a | That b | These a b

Since version 1, this package was split into parts:

• https://hackage.haskell.org/package/semialign For Align and Zip type-classes.

• https://hackage.haskell.org/package/semialign-indexed For SemialignWithIndex class, providing ialignWith and izipWith

• https://hackage.haskell.org/package/these-lens For lens combinators.

• http://hackage.haskell.org/package/monad-chronicle For transformers variant of These.

Skylighting is a syntax highlighting library with support for over one hundred languages. It derives its tokenizers from XML syntax definitions used by KDE's KSyntaxHighlighting framework, so any syntax supported by that framework can be added. An optional command-line program is provided. Skylighting is intended to be the successor to highlighting-kate. This package provides generated syntax modules based on the KDE XML definitions provided by the skylighting-core package.

This package provides optimized functions to determine the edit distances for fuzzy matching, including Levenshtein and restricted Damerau-Levenshtein algorithms.

This package provides a library that performs fast, accurate conversion between double precision floating point and text.

This library provides an implementation of the older blaze-builder interface in terms of the new builder that shipped with bytestring-0.10.4.0. This implementation is mostly intended as a bridge to the new builder, so that code that uses the old interface can interoperate with code that uses the new implementation.

This library provides core modules of a markup combinator library for Haskell.

This package provides memory abstractions, such as chunk of memory, polymorphic byte array management and manipulation functions. It contains a polymorphic byte array abstraction and functions similar to strict ByteString, different type of byte array abstraction, raw memory IO operations (memory set, memory copy, ..) and more
