D-Bus is a simple, message-based protocol for inter-process communication, which allows applications to interact with other parts of the machine and the user's session using remote procedure calls. D-Bus is a essential part of the modern Linux desktop, where it replaces earlier protocols such as CORBA and DCOP. This library is an implementation of the D-Bus protocol in Haskell. It can be used to add D-Bus support to Haskell applications, without the awkward interfaces common to foreign bindings.

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

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.

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

This package provides a Haskell library including a Storable instance for Complex which is binary compatible with C99, C++ and Fortran complex data types.

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.

This package contains the C sources of LPeg, as well as some tiny Haskell helper to load the package. . <http://www.inf.puc-rio.br/~roberto/lpeg/>

This library provides free monads, which are useful for many tree-like structures and domain specific languages. If f is a Functor then the free Monad on f is the type of trees whose nodes are labeled with the constructors of f. The word "free" is used in the sense of "unrestricted" rather than "zero-cost": Free f makes no constraining assumptions beyond those given by f and the definition of Monad.

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

This package backports the Control.Monad.Except module from mtl (if using mtl-2.2.0.1 or earlier), which reexports the ExceptT monad transformer and the MonadError class.

This package should only be used if there is a need to use the Control.Monad.Except module specifically. If you just want the mtl class instances for ExceptT, use transformers-compat instead, since mtl-compat does nothing but reexport the instances from that package.

Note that unlike how mtl-2.2 or later works, the Control.Monad.Except module defined in this package exports all of ExceptT's monad class instances. Therefore, you may have to declare import Control.Monad.Except () at the top of your file to get all of the ExceptT instances in scope.

This package defines new symbols for a number of functions, operators and types in the base package. All symbols are documented with their actual definition and information regarding their Unicode code point. They should be completely interchangeable with their definitions. For further Unicode goodness you can enable the UnicodeSyntax language extension. This extension enables Unicode characters to be used to stand for certain ASCII character sequences, i.e. → instead of ->, ∀ instead of forall and many others.

This package provides a module to use Skylighting to perform syntax highlighting and display the results in Brick-based interfaces.

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read and write Markdown and (subsets of) other formats, such as HTML, reStructuredText, LaTeX, DocBook, and many more.

Pandoc extends standard Markdown syntax with footnotes, embedded LaTeX, definition lists, tables, and other features. A compatibility mode is provided for those who need a drop-in replacement for Markdown.pl.

__This package is deprecated__. Please, use genByteString from the [random package (version >=1.2)](https://hackage.haskell.org/package/random) instead. . Efficient generation of random bytestrings. The implementation populates uninitialized memory with uniformily distributed random 64 bit words (and 8 bit words for remaining bytes at the end of the bytestring). . Random words are generated using the PRNG from the [mwc-random](https://hackage.haskell.org/package/mwc-random) package or the [pcg-random](https://hackage.haskell.org/package/pcg-random) package. It is also possible to use a custom PRNG by providing an instance for the RandomWords type class and using the function generate from the module "Data.ByteString.Random.Internal". . The generated byte strings are suitable for statistical applications. They are /not/ suitable for cryptographic applications. .  . 

Trifecta is a modern parser combinator library for Haskell, with slicing and Clang-style colored diagnostics.

This Haskell library algorithms for vector arrays.

The options package lets library and application developers easily work with command-line options.

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.

This package allows you to work with WAVE and RF64 files in Haskell.

Concatenative gives Haskell Factor-style combinators and arrows for postfix notation. For more information on stack based languages, see https://concatenative.org.

This library provides a half-precision floating-point computation library for Haskell.

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 a mid-Level PostgreSQL client library, forked from ghc-mysql-simple.
