This library provides a wrapper to the Linux kernel's inotify feature, allowing applications to subscribe to notifications when a file is accessed or modified.

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

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.

Hpack is a format for Haskell packages. It is an alternative to the Cabal package format and follows different design principles. Hpack packages are described in a file named package.yaml. Both cabal2nix and stack support package.yaml natively. For other build tools the hpack executable can be used to generate a .cabal file from package.yaml.

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.

FoldMap lists are lists represented by their foldMap function. FoldMap lists have O(1) cons, snoc and append, just like DLists, but other operations might have favorable performance characteristics as well. These wild claims are still completely unverified though.

This package provides a simple text templating system used by pandoc.

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 library provides various semigroups, specialized containers and a general map/reduce framework for Haskell.

This library provides functions available in later versions of base to a wider range of compilers, without requiring you to use CPP pragmas in your code. This package provides the same API as the base-compat library, but depends on compatibility packages (such as semigroups) to offer a wider support window than base-compat, which has no dependencies.

The ghc-ini Haskell library lets programmers quickly and easily read and write configuration files in the simple INI format.

This Haskell package provides support for computations which consume random values.

This package provides a Haskell library for working with files and directories. It includes code for pattern matching, finding files, modifying file contents, and more.

The Union/Find algorithm implements these operations in (effectively) constant-time:

1. Check whether two elements are in the same equivalence class.

2. Create a union of two equivalence classes.

3. Look up the descriptor of the equivalence class.

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

This Haskell package was originally present in classy-prelude.

ghc-blaze-textual is a fast Haskell library for rendering common Haskell datatypes in text form using the ghc-blaze-builder library.

This Haskell package provides additional data structures, and other added capabilities layered on top of the Par monad.

This package provides a Haskell library for globbing: matching patterns against file paths.

HAProxy protocol version 1.5 support (see http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt) for applications using io-streams. The proxy protocol allows information about a networked peer (like remote address and port) to be propagated through a forwarding proxy that is configured to speak this protocol.

This library provides fast, packed, strict storable arrays with a list interface, a chunky lazy list interface with variable chunk size and an interface for write access via the ST monad. This is much like bytestring and binary but can be used for every Foreign.Storable.Storable type. See also https://hackage.haskell.org/package/vector, a library with a similar intention.

This library does not do advanced fusion optimization, since especially for lazy vectors this would either be incorrect or not applicable. See https://hackage.haskell.org/package/storablevector-streamfusion for a library that provides fusion with lazy lists.

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

Cross platform library for file creation, modification, and deletion notification. This library builds upon existing libraries for platform specific Windows, Mac, and Linux file system event notification.

This package provides extra instances for type-classes in the [indexed-traversable](https://hackage.haskell.org/package/indexed-traversable) package. . The intention is to keep this package minimal; it provides instances that formerly existed in @lens@ or @optics-extra@. We recommend putting other instances directly into their defining packages. The @indexed-traversable@ package is light, having only GHC boot libraries as its dependencies.
