This package provides a library and an executable for working with derived Show instances. By using the library, derived Show instances can be parsed into a generic data structure. The ppsh tool uses the library to produce human-readable versions of Show instances, which can be quite handy for debugging Haskell programs. We can also render complex generic values into an interactive Html page, for easier examination.

This package provides a UTF-8 aware subset of Lua's string module for Haskell. The functions provided by this module are upper, lower, len, reverse, and sub.

This package provides an implementation of n-ary sums and n-ary products. The module Data.SOP is the main module of this library and contains more detailed documentation. The main use case of this package is to serve as the core of generics-sop.

This library provides the natural numbers for Haskell.

This package provides a simple applicative parser in Parsec style.

This package provides Haskell modules for accessing and manipulating fields of records.

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

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 provides a drop-in replacement for the standard filepath library, operating on RawFilePath values rather than FilePath values to get the speed benefits of using ByteStrings.

Hslogger lets each log message have a priority and source be associated with it. The programmer can then define global handlers that route or filter messages based on the priority and source. It also has a syslog handler built in.

A clone of wl-pprint for use with the text library.

This package provides Haskell bindings to bzlib and Conduit support for streaming compression and decompression.

This package provides a simple XML library for Haskell.

This Haskell package defines typeclasses used for converting Haskell data types to and from HTTP API data.

Provides default instances for types from the containers package.

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

Automatically discover and run Hspec tests . <http://hspec.github.io/hspec-discover.html>

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

C->Haskell assists in the development of Haskell bindings to C libraries. It extracts interface information from C header files and generates Haskell code with foreign imports and marshaling. Unlike writing foreign imports by hand (or using hsc2hs), this ensures that C functions are imported with the correct Haskell types.

Lifted-base exports IO operations from the base library lifted to any instance of MonadBase or MonadBaseControl. Note that not all modules from base are converted yet. The package includes a copy of the monad-peel test suite written by Anders Kaseorg.

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.

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.

This library provides a number of common functions and types useful in statistics. We focus on high performance, numerical robustness, and use of good algorithms. Where possible, we provide references to the statistical literature.

The library's facilities can be divided into four broad categories:

• Working with widely used discrete and continuous probability distributions. (There are dozens of exotic distributions in use; we focus on the most common.)

• Computing with sample data: quantile estimation, kernel density estimation, histograms, bootstrap methods, significance testing, and regression and autocorrelation analysis.

• Random variate generation under several different distributions.

• Common statistical tests for significant differences between samples.
