This library implements a technique to catch all exceptions raised within an enclosed computation, while remaining responsive to (external) asynchronous exceptions.

This library provides exception safe semaphores that can be used in place of QSem, QSemN, and SampleVar, all of which are not exception safe and can be broken by killThread.

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>.

This library provides a framework for size-based enumerations.

This is a simple time library providing a simple but powerful and performant API. The backbone of the library are the Timeable and Time type classes. Each Timeable instances can be converted to a type that has a Time instances, and thus are different representations of current time.

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

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 provides an API to Haddock, the documentation-generation tool for Haskell libraries.

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.

The functions for creating temporary files and directories in the base library are quite limited. The unixutils package contains some good ones, but they aren't portable to Windows. This library just repackages the Cabal implementations of its own temporary file and folder functions so that you can use them without linking against Cabal or depending on it being installed. This is a better maintained fork of the "temporary" package.

ByteString-backed Handles

This is a Haskell module for PortMidi audio library, which supports real-time MIDI input and output.

Protolude gives you sensible defaults for writing custom Preludes to replace the standard one provided by GHC.

Utilities for dealing with IEEE floating point numbers, ported from the Tango math library; approximate and exact equality comparisons for general types.

This library provides the POSIX regex backend used by the Haskell library regex-base.

This library defines an existential type Some'. . @ data Some f where \ Some :: f a -> Some f @ . in few variants, and utilities to work with it. . If you are unsure which variant to use, use the one in "Data.Some" module.

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

The zip-archive library provides functions for creating, modifying, and extracting files from zip archives in Haskell.

This package is a compatibility package for a singleton data type . > data Solo a = Solo a . Note: it's not a @newtype@ . @Solo@ is available in @base-4.16@ (GHC-9.2).

This package provides Haskell bindings to the the POSIX network database (<netdb.h>) API.

This package contains the Control.Monad.Fail module providing the MonadFail class that became available in base-4.9.0.0 for older base package versions. This package turns into an empty package when used with GHC versions which already provide the Control.Monad.Fail module.

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 defines orphan instances that mimic instances available in later versions of base to a wider (older) range of compilers.

This package provides functions for signed 15.16 precision fixed point arithmetic.
