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 package provides Haskell bindings to the setlocale C function.

This package defines the type class MonadBaseControl, a subset of MonadBase into which generic control operations such as catch can be lifted from IO or any other base monad.

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.

Provides default instances for types from the dlist package.

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

This Haskell package provides the core MonadUnliftIO typeclass, instances for base and transformers, and basic utility functions.

This package provides a quasiquoter for non-interpolated strings, texts and bytestrings.

This package provides a library implementing the XDG Base Directory spec.

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.

This package provides an abstract class to manipulate sequence of bytes. The use case of this class is abstracting manipulation of types that are just wrapping a bytestring with stronger and more meaniful name.

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/.

ghc-doctest-driver-gen is a Doctest's driver file generator. It lets you automatically generate driver file for Doctest's Cabal integration.

Haskeline wrapper for GHCi-like REPL interfaces. Composable with normal mtl transformers.

Using the API Annotations available from GHC 7.10.2, this library provides a means to round-trip any code that can be compiled by GHC, currently excluding .lhs files.

This package provides a canonical anonymous 1-tuple type missing from Haskell for attaching typeclass instances.

There is also the OneTuple package which by using a boxed data-type provides a 1-tuple type which has laziness properties which are more faithful to the ones of Haskell's native tuples; whereas the primary purpose of Only is to provide the traditionally so named type-wrapper for attaching typeclass instances.

The PGP Word List consists of two phonetic alphabets, each with one word per possible byte value. A string of bytes is translated with these alphabets, alternating between them at each byte.

The PGP words corresponding to the bytes 5B 1D CA 6E are "erase breakaway spellbind headwaters", for example.

For further information, see http://en.wikipedia.org/wiki/PGP_word_list.

This package provides a monad transformer version of the ST monad for strict state threads.

A PointedList tracks the position in a non-empty list which works similarly to a zipper. A current item is always required, and therefore the list may never be empty. A circular PointedList wraps around to the other end when progressing past the actual edge.

This package provides functions to prevent or capture writing to stdout and other handles.

This library uses GHC.Generics to derive efficient optics (traversals, lenses and prisms) for algebraic data types in a type-directed way, with a focus on good type inference and error messages when possible. This package is the shared internal logic of the generic-lens and generic-optics libraries.

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.

This package provides a means of generating tag files for Emacs and Vim.

This package provides an interface to the directory package for users of path. It also implements some missing stuff like recursive scanning and copying of directories, working with temporary files/directories, and more.
