This package provides a writer monad for multi-line string literals.

Lightweight pure data validation based on Applicative and Selective functors.

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.

This package addresses the 'configuration problem' which is propagating configurations that are available at run-time, allowing multiple configurations to coexist without resorting to mutable global variables or System.IO.Unsafe.unsafePerformIO.

The texmath library provides functions to read and write TeX math, presentation MathML, and OMML (Office Math Markup Language, used in Microsoft Office). Support is also included for converting math formats to pandoc's native format (allowing conversion, via pandoc, to a variety of different markup formats). The TeX reader supports basic LaTeX and AMS extensions, and it can parse and apply LaTeX macros.

This Haskell library provides a two-dimensional zipper data structure for editing text. The structure represents the body of text and an editing cursor which can be moved through it, along with a set of editing transformations.

Text zippers are generalized over the set of data types that might be used to store lists of characters (e.g., String, T.Text, etc.). Implementations using both of these examples are provided.

This package provides two simple conduit wrappers around STM channels: a source and a sink.

This is a lightweight package providing commonly useful parser combinators.

This package provides a Haskell type inhabited by finitely many values and indexed by type-level naturals.

Please see the README and documentation at <https://www.stackage.org/package/githash>

This package defines a class, Hashable, for types that can be converted to a hash value. This class exists for the benefit of hashing-based data structures. The package provides instances for basic types and a way to combine hash values.

This package provides the bytestring builder that is debuting in bytestring-0.10.4.0, which should be shipping with GHC 7.8. Compatibility package for older packages.

This package provides a binary serialization library, similar to binary, that introduces an isolate primitive for parser isolation, and labeled blocks for better error messages.

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 ordered containers of intervals, with efficient search for all keys containing a point or overlapping an interval. See the example code on the home page for a quick introduction.

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

This package provides utilities and combinators for parsing command line options in Haskell.

This Haskell package lets you automatically generate lenses for data types; code was extracted from the lens package, and therefore generated lenses are fully compatible with ones generated by lens (and can be used both from lens and microlens).

This package tries to compat as many time features as possible.

This library implements mid-level Haskell bindings to the MySQL mysqlclient client library. It is aimed at speed and ease of use.

This package provides Haskell bindings for the OpenGL graphics system (GL, version 4.5) and its accompanying utility library (GLU, version 1.3).

This library provides a framework for size-based enumerations.

This library provides instances of Binary for the types defined in the vector package, making it easy to serialize vectors to and from disk. We use the generic interface to vectors, so all vector types are supported. Specific instances are provided for unboxed, boxed and storable vectors.

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