This library provides exception safe semaphores that can be used in place of QSem, QSemN, and SampleVar, all of which are not exception safe and can be broken by killThread.

This library provides fast, packed, strict storable arrays with a list interface, a chunky lazy list interface with variable chunk size and an interface for write access via the ST monad. This is much like bytestring and binary but can be used for every Foreign.Storable.Storable type. See also https://hackage.haskell.org/package/vector, a library with a similar intention.

This library does not do advanced fusion optimization, since especially for lazy vectors this would either be incorrect or not applicable. See https://hackage.haskell.org/package/storablevector-streamfusion for a library that provides fusion with lazy lists.

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>

A thread safe API to write a line of textual data to a Handle, such as sending some messages to the terminal - that has the following properties:

• Properly handle character encoding settings on the Handle

• For reasonably sized messages, ensure that the entire message is written in one chunk to avoid interleaving data with other threads

• Avoid unnecessary memory allocations and copies

• Minimize locking.

This package includes backported versions of types that were added to transformers in transformers 0.3 and 0.4 for users who need strict transformers 0.2 or 0.3 compatibility to run on old versions of the platform, but also need those types.

This Haskell package supports the definition of generic functions. Datatypes are viewed in a uniform, structured way: the choice between constructors is represented using an n-ary sum, and the arguments of each constructor are represented using an n-ary product.

This Haskell package was originally present in classy-prelude.

This package provides a generic interface for multiple Vty platforms in one package so you don't have to conditionally depend on them in your cabal file.

This Haskell library provides a simple purely functional circular list, or ring, data type: a circular data structure such that if you continue rotating the ring in either direction, you'll eventually return to the element you first observed.

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.

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.

A decimal number has an integer mantissa and a negative exponent. The exponent can be interpreted as the number of decimal places in the value.

This package provides a version of ghc-hspec-expectations generalized to MonadIO.

Zstandard compression packaged as a conduit. This is a very thin wrapper around the official hs-zstd interface.

This is a small wrapper around the directory, unix, and Win32 packages, for use with system-filepath. It provides a consistent API to the various versions of these packages distributed with different versions of GHC. In particular, this library supports working with POSIX files that have paths which can't be decoded in the current locale encoding.

This package provides a simple wrapper to show the used CPU time of monadic computation with an IO base.

This library lets you write interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse. Reflex is a fully-deterministic, higher-order FRP interface and an engine that efficiently implements that interface.

This package provides a simple XML library for Haskell.

An implementation of the git-lfs protocol.

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 Haskell package provides Monomorphic variants of the Functor, Foldable, and Traversable typeclasses. If you understand Haskell's basic typeclasses, you understand mono-traversable. In addition to what you are used to, it adds on an IsSequence typeclass and has code for marking data structures as non-empty.

This package attempts to provide support for using Amazon Web Services like S3 (storage), SQS (queuing) and others to Haskell programmers. The ultimate goal is to support all Amazon Web Services.

This library provides functions for use in parsing indentation sensitive contexts. It parses blocks of lines all indented to the same level as well as lines continued at an indented level below.
