This package provides a family of combinators for defining webservices APIs and serving them . You can learn about the basics in the <http://docs.servant.dev/en/stable/tutorial/index.html tutorial>. . <https://github.com/haskell-servant/servant/blob/master/servant/CHANGELOG.md CHANGELOG>

This Haskell package provides a family of type-safe templates with simple variable interpolation. Shakespeare templates can be used inline with a quasi-quoter or in an external file and it interpolates variables according to the type being inserted.

This package provides types and combinators for linear algebra on free vector spaces.

This package provides Haskell bindings to the setlocale C function.

Regex-tdfa is a pure Haskell regular expression library implementing POSIX extended regular expressions. It is a "tagged" DFA regex engine. It is inspired by libtre.

The threadDelay and timeout functions from the Haskell base library use the bounded Int type for specifying the delay or timeout period. This package provides alternative functions which use the unbounded Integer type.

A library for generating concise pretty printers based on precedence rules.

This library provides a conduit-based, streaming interface for extracting and creating tar files.

A package for convenient access to high-resolution clock and timer functions of different operating systems via a unified API.

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

The mockery package provides support functions for automated testing.

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 package defines an Active abstraction for time-varying values with finite start and end times. It is used for describing animations within the diagrams framework.

This library provides a fast parser combinator library, aimed particularly at dealing efficiently with network protocols and complicated text/binary file formats.

This package contains a wrapped name module for TimeLocale.

Expose Haskell objects to Lua with an object oriented interface.

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 library provides a type-safe embedded domain specific language (EDSL) for SQL queries that works with SQL backends as provided by ghc-persistent. Its language closely resembles SQL, so you don't have to learn new concepts, just new syntax, and it's fairly easy to predict the generated SQL and optimize it for your backend.

Async provides a library to run IO operations asynchronously, and wait for their results. It is a higher-level interface over threads in Haskell, in which Async a is a concurrent thread that will eventually deliver a value of type a.

This package extends https://hackage.haskell.org/package/process. It allows you to read process input and output as ByteStrings or Text, or write your own ProcessOutput instance. It also provides lazy process input and output, and a ProcessMaker class for more flexibility in the process creation API.

The major use of These of this is provided by the align member of Semialign class, representing a generalized notion of "zipping with padding" that combines structures without truncating to the size of the smaller input. It turns out that zip operation fits well the Semialign class, forming lattice-like structure.

This is a pretty printing library based on Wadler's paper A Prettier Printer. This version allows the library user to declare overlapping instances of the Pretty class.

Various tasty helpers and utilities to test HsLua oparations. Built on top of tasty-hunit.

This package provides bindings to the ALSA simple mixer API.
