The package provides mutable and immutable bit arrays.

This package provides a collection of Haskell functions for splitting lists into parts, akin to the split function found in several mainstream languages.

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 library provides a pure Haskell implementation of the Unicode Collation Algorithm described at http://www.unicode.org/reports/tr10/. It is not as fully-featured or as performant as text-icu, but it avoids a dependency on a large C library. Locale-specific tailorings are also provided.

ghc-citeproc parses Citation Style Language style files and uses them to generate a list of formatted citations and bibliography entries. For more information about CSL, see https://citationstyles.org/.

Network recv based on buffer pools

This package provides a modular backend for rendering diagrams created with the diagrams embedded domain-specific language (EDSL) to Scalable Vector Graphics (SVG) files.

This package provides the tldr command and a Haskell client library allowing users to update and view tldr pages from a shell. The tldr pages are a community effort to simplify the man pages with practical examples.

GLURaw is a raw Haskell binding for the GLU 1.3 OpenGL utility library. It is basically a 1:1 mapping of GLU's C API, intended as a basis for a nicer interface.

This package (formerly binary-serialise-cbor) provides an efficient implementation of the Concise Binary Object Representation (CBOR), as specified by RFC 7049 at https://tools.ietf.org/html/rfc7049.

If you are looking for a library for serialisation of Haskell values, have a look at the https://hackage.haskell.org/package/serialise package, which is built upon this library.

An implementation of the standard bijection between CBOR and JSON is provided by the https://hackage.haskell.org/package/cborg-json package.

Also see https://hackage.haskell.org/package/cbor-tool for a convenient command-line utility for working with CBOR data.

This package provides a Haskell library for setting environment variables.

This library provides tools to create command line interfaces with ease.

This package turn Data.Serialize Gets and Puts into Sources, Sinks, and Conduits.

This is a small wrapper around the directory, unix, and Win32 packages, for use with system-filepath. It provides a consistent API to the various versions of these packages distributed with different versions of GHC. In particular, this library supports working with POSIX files that have paths which can't be decoded in the current locale encoding.

This package endows Data.Time, from the time package, with several data types and functions for enhanced processing of timezones. For one way to create timezone series, see the ghc-timezone-olson package.

Lifted-base exports IO operations from the base library lifted to any instance of MonadBase or MonadBaseControl. Note that not all modules from base are converted yet. The package includes a copy of the monad-peel test suite written by Anders Kaseorg.

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

Pretty-simple is a pretty printer for Haskell data types that have a Show instance.

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

Haskell-Source with Extensions (HSE, haskell-src-exts) is an extension of the standard haskell-src package, and handles most registered syntactic extensions to Haskell. All extensions implemented in GHC are supported. Apart from these standard extensions, it also handles regular patterns as per the HaRP extension as well as HSX-style embedded XML syntax.

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.

Haskell bindings to the International Components for Unicode (ICU) libraries. These libraries provide robust and full-featured Unicode services on a wide variety of platforms. . Features include: . * Both pure and impure bindings, to allow for fine control over efficiency and ease of use. . * Breaking of strings on character, word, sentence, and line boundaries. . * Access to the Unicode Character Database (UCD) of character metadata. . * String collation functions, for locales where the conventions for lexicographic ordering differ from the simple numeric ordering of character codes. . * Character set conversion functions, allowing conversion between Unicode and over 220 character encodings. . * Unicode normalization. (When implementations keep strings in a normalized form, they can be assured that equivalent strings have a unique binary representation.) . * Regular expression search and replace. . * Security checks for visually confusable (spoofable) strings. . * Bidirectional Unicode algorithm . * Calendar objects holding dates and times. . * Number and calendar formatting.

This package provides algorithms on Conduits, including higher level asynchronous processing and some other utilities.

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.
