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.

The HMatrix package provides a Haskell library for dealing with linear systems, matrix decompositions, and other numerical computations based on BLAS and LAPACK.

This library provides everything that microlens provides plus instances to make each, at, and ix usable with arrays, ByteString, and containers. This package is a part of the microlens family; see the readme on Github.

This library provides Haskell bindings to the MySQL mysqlclient client library. It is a fairly faithful, low level library that implements most of the MySQL client API. The major departure from the C API is that in Haskell, resource management is mostly automatic and safe.

This library deliberately avoids the question of providing a ``good'' API. Its purpose is to serve as a base upon which higher-level libraries can be built.

HAProxy protocol version 1.5 support (see http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt) for applications using io-streams. The proxy protocol allows information about a networked peer (like remote address and port) to be propagated through a forwarding proxy that is configured to speak this protocol.

This Haskell library provides pointed and copointed data types.

Cross platform library for file creation, modification, and deletion notification. This library builds upon existing libraries for platform specific Windows, Mac, and Linux file system event notification.

This library provides the core data types and functions for parsing Commonmark. The parser is fully Commonmark-compliant and passes the test suite. It is designed to be customizable and easily extensible. To customize the output, create an AST, or support a new output format, one need only define some new typeclass instances. It is also easy to add new syntax elements or modify existing ones.

Accurate information about source positions is available for all block and inline elements. Thus the library can be used to create an accurate syntax highlighter or an editor with live preview. The parser has been designed for robust performance even in pathological cases that tend to cause stack overflows or exponential slowdowns in other parsers, with parsing speed that varies linearly with input length.

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

Per Conor McBride, the Newtype typeclass represents the packing and unpacking of a newtype, and allows you to operate under that newtype with functions such as ala'.

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 tiny package contains the class ObjectName, which corresponds to the general notion of explicitly handled identifiers for API objects, e.g. a texture object name in OpenGL or a buffer object name in OpenAL.

This package provides a simple logging abstraction that allows multiple back-ends.

This library provides file handling utilities for Haskell.

This package exports a module which is the recommended starting point for using microlens if you aren't trying to keep your dependencies minimal. By importing Lens.Micro.Platform you get all functions and instances from microlens, microlens-th, microlens-mtl, microlens-ghc, as well as instances for Vector, Text, and HashMap. The minor and major versions of microlens-platform are incremented whenever the minor and major versions of any other microlens package are incremented, so you can depend on the exact version of microlens-platform without specifying the version of microlens you need. This package is a part of the microlens family; see the readme on Github.

This package provides Haskell bindings for libcmark-gfm, the reference parser for GitHub Flavored Markdown, a fully specified variant of Markdown. It includes sources for libcmark-gfm and does not require prior installation of the C library.

The word-wrap Haskell library wraps long lines of text.

This library provides the natural numbers for Haskell.

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>

Brick helps you write terminal user interfaces (TUIs). You write an event handler and a drawing function and the library does the rest.

A cross-platform library with functions for adjusting code pages on Windows. On all other operating systems, the library does nothing.

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

This library provides the natural numbers for Haskell.

This library provides extra functions for the standard Haskell libraries. Most functions are simple additions, filling out missing functionality. A few functions are available in later versions of GHC, but this package makes them available back to GHC 7.2.
