This library is for working with \".tar\" archive files. It can read and write a range of common variations of the tar archive format including V7, POSIX USTAR and GNU formats. It provides support for packing and unpacking portable archives. This makes it suitable for distribution but not backup because details like file ownership and exact permissions are not preserved. It also provides features for random access to archive content using an index.

This package provides a simple XML library for Haskell.

This tiny package contains the class ObjectName, which corresponds to the general notion of explicitly handled identifiers for API objects, e.g. a texture object name in OpenGL or a buffer object name in OpenAL.

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

This package provides a variety of alternative parser combinator libraries, including the original HuttonMeijer set. The Poly sets have features like good error reporting, arbitrary token type, running state, lazy parsing, and so on. Finally, Text.Parse is a proposed replacement for the standard Read class, for better deserialisation of Haskell values from Strings.

This module defines the Pandoc data structure, which is used by pandoc to represent structured documents. It also provides functions for building up, manipulating and serialising Pandoc structures.

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 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.

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

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

This Haskell library provides pointed and copointed data types.

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."

This package provides Haskell bindings to SDL2_ttf C++ library.

wordexp(3) wrapper library for Haskell to perform word expansion like a posix-shell.

The module Data.CaseInsensitive provides the CI type constructor which can be parameterised by a string-like type like: String, ByteString, Text, etc. Comparisons of values of the resulting type will be insensitive to cases.

The haskell-src package provides support for manipulating Haskell source code. The package provides a lexer, parser and pretty-printer, and a definition of a Haskell abstract syntax tree (AST). Common uses of this package are to parse or generate Haskell 98 code.

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.

This library provides phantom types for Haskell 98, to avoid having to unsafely pass dummy arguments.

A clean and powerful stream processing library that lets you build and connect reusable streaming components. Advantages over traditional streaming libraries:

• Concise API: Use simple commands like for, (>->), await, and yield

• Blazing fast: Implementation tuned for speed, including shortcut fusion

• Lightweight Dependency: pipes is small and compiles very rapidly, including dependencies

• Elegant semantics: Use practical category theory

• ListT: Correct implementation of ListT that interconverts with pipes

• Bidirectionality: Implement duplex channels

hscolour is a small Haskell script to colourise Haskell code. It currently has six output formats: ANSI terminal codes (optionally XTerm-256colour codes), HTML 3.2 with <font> tags, HTML 4.01 with CSS, HTML 4.01 with CSS and mouseover annotations, XHTML 1.0 with inline CSS styling, LaTeX, and mIRC chat codes.

This package provides IO operations from async package lifted to any instance of MonadBase or MonadBaseControl.

Uniplate is a library for writing simple and concise generic operations. Uniplate has similar goals to the original Scrap Your Boilerplate work, but is substantially simpler and faster.

This library provides a wrapper to mmap, allowing files or devices to be lazily loaded into memory as strict or lazy ByteStrings, ForeignPtrs or plain Ptrs, using the virtual memory subsystem to do on-demand loading.

Boxes is a pretty-printing library for laying out text in two dimensions, using a simple box model.
