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

IP Routing Table is a tree of IP ranges to search one of them on the longest match base. It is a kind of TRIE with one way branching removed. Both IPv4 and IPv6 are supported.

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

This package provides a quasiquoter for non-interpolated strings, texts and bytestrings.

This package provides portable implementations of parts of the unix package. This package re-exports the unix package when available. When it isn't available, portable implementations are used.

This package provides optimized functions to determine the edit distances for fuzzy matching, including Levenshtein and restricted Damerau-Levenshtein algorithms.

This Haskell library offers (among other things) the following selection of synchronisation primitives:

• Broadcast: Wake multiple threads by broadcasting a value.

• Event: Wake multiple threads by signalling an event.

• Lock: Enforce exclusive access to a resource. Also known as a binary semaphore or mutex. The package additionally provides an alternative that works in the STM monad.

• RLock: A lock which can be acquired multiple times by the same thread. Also known as a reentrant mutex.

• ReadWriteLock: Multiple-reader, single-writer locks. Used to protect shared resources which may be concurrently read, but only sequentially written.

• ReadWriteVar: Concurrent read, sequential write variables.

Please consult the API documentation of the individual modules for more detailed information.

This package was inspired by the concurrency libraries of Java and Python.

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.

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.

This library provides a continuation-based, backtracking, logic programming monad. An adaptation of the two-continuation implementation found in the paper "Backtracking, Interleaving, and Terminating Monad Transformers" available online.

This library provides Numeric.Interval.Interval, which represents a closed, convex set of floating point values.

This is a library for testing code involving bottoms or infinite values. For the underlying theory and a larger example involving use of QuickCheck, see the article "Chasing Bottoms A Case Study in Program Verification in the Presence of Partial and Infinite Values".

This package (formerly binary-serialise-cbor) provides an efficient implementation of the Concise Binary Object Representation (CBOR), as specified by RFC 7049 at https://tools.ietf.org/html/rfc7049.

If you are looking for a library for serialisation of Haskell values, have a look at the https://hackage.haskell.org/package/serialise package, which is built upon this library.

An implementation of the standard bijection between CBOR and JSON is provided by the https://hackage.haskell.org/package/cborg-json package.

Also see https://hackage.haskell.org/package/cbor-tool for a convenient command-line utility for working with CBOR data.

This Haskell library provides utilities creating, comparing, parsing and printing Universally Unique Identifiers or UUIDs.

This package provides a library that performs fast, accurate conversion between double precision floating point and text.

This package provides semigroups for Haskell. In mathematics, a semigroup is an algebraic structure consisting of a set together with an associative binary operation. A semigroup generalizes a monoid in that there might not exist an identity element. It also (originally) generalized a group (a monoid with all inverses) to a type where every element did not have to have an inverse, thus the name semigroup.

This package provides a pure interface for compressing and decompressing streams of data represented as lazy ByteStrings. It uses the zlib C library so it has high performance. It supports the zlib, gzip and raw compression formats. It provides a convenient high level API suitable for most tasks and for the few cases where more control is needed it provides access to the full zlib feature set.

This package provides instances to push and receive any datatype encodable as JSON to and from the Lua stack.

The haskell-src package provides support for manipulating Haskell source code. The package provides a lexer, parser and pretty-printer, and a definition of a Haskell abstract syntax tree (AST). Common uses of this package are to parse or generate Haskell 98 code.

This package provides bifunctors for Haskell.

GNU ncurses is a library for creating command-line application with pseudo-graphical interfaces. This package is a nice, modern binding to GNU ncurses.

This library provides some useful tools from the C standard library.

This Haskell library provides a purely functional interface for statistics based on hmatrix and GSL.

This Haskell package allows Haskell programs to access data storage systems like PostgreSQL, SQLite, and MariaDB in a type-safe way.
