This package provides low-dependency functionality commonly needed by various Haskell streaming data libraries, such as conduit and pipes.

This package provides ANSI terminal support for Haskell. It allows cursor movement, screen clearing, color output showing or hiding the cursor, and changing the title.

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

vty is a terminal GUI library in the niche of ncurses, intended to be easy to use and to provide good support for common terminal types.

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.

This package provides instances for QuickCheck's \"Arbitrary\" typeclass.

This Haskell library provides a type class for the error function, erf, and related functions. Instances for Float and Double.

This library provides Pure Haskell solver routines for use by the diagrams framework. It currently includes routines for finding real roots of low-degree (n < 5) polynomials, and solving tridiagonal and cyclic tridiagonal linear systems.

This Haskell package provides a lens library, just like ghc-lens, but smaller. It provides essential lenses and traversals (like _1 and _Just), as well as ones which are simply nice to have (like each, at, and ix), and some combinators (like failing and singular), but everything else is stripped. As the result, this package has no dependencies.

This library provides convenient combinators for working with and building parsing combinator libraries. Given a few simple instances, you get access to a large number of canned definitions. Instances exist for the parsers provided by parsec, attoparsec and base's Text.Read.

The package provides mutable and immutable bit arrays.

This package provides several functions to quickly search for substrings in strict or lazy ByteStrings. It also provides functions for breaking or splitting on substrings and replacing all occurrences of a substring (the first in case of overlaps) with another.

This package provides a data structure representing a bidirectional mapping between two key types. Each value in the bimap is associated with exactly one value of the opposite type.

This is a lightweight package providing commonly useful parser combinators.

This library defines an existential type Some'. . @ data Some f where \ Some :: f a -> Some f @ . in few variants, and utilities to work with it. . If you are unsure which variant to use, use the one in "Data.Some" module.

An implementation of the git-lfs protocol.

The ghc-ini Haskell library lets programmers quickly and easily read and write configuration files in the simple INI format.

This library provides parsers and printers for bencoded data. Bencode is the encoding used by the peer-to-peer file sharing system BitTorrent for storing and transmitting loosely structured data.

This Haskell package provides support for computations which consume random values.

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 package provides a newtype wrapper with FromJSON/ToJSON instances customisable via a phantom type parameter. The instances can be rendered to the original type using DerivingVia.

This package provides an API to Haddock, the documentation-generation tool for Haskell libraries.

This package provides Type-level booleans.

This package provides extra instances for type-classes in the [indexed-traversable](https://hackage.haskell.org/package/indexed-traversable) package. . The intention is to keep this package minimal; it provides instances that formerly existed in @lens@ or @optics-extra@. We recommend putting other instances directly into their defining packages. The @indexed-traversable@ package is light, having only GHC boot libraries as its dependencies.
