Enter the query into the form above. You can look for specific version of a package by using @ symbol like this: gcc@10.
API method:
GET /api/packages?search=hello&page=1&limit=20
where search is your query, page is a page number and limit is a number of items on a single page. Pagination information (such as a number of pages and etc) is returned
in response headers.

This package provides a simple wrapper to show the used CPU time of monadic computation with an IO base.
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.
SDL_image is an image file loading library. It loads images as SDL surfaces, and supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, TGA, TIFF, XCF, XPM, XV.
Shelly provides convenient systems programming in Haskell, similar in spirit to POSIX shells. Shelly is originally forked from the Shellish package.
This Haskell package provides an abstract interface to highly-parameterizable queues/deques.
Background: There exists a feature space for queues that extends between:
Simple, single-ended, non-concurrent, bounded queues
Double-ended, thread-safe, growable queues with important points in between (such as the queues used for work stealing).
This package includes an interface for Deques that allows the programmer to use a single API for all of the above, while using the type system to select an efficient implementation given the requirements (using type families).
This package also includes a simple reference implementation based on IORef and Data.Sequence.
This package provides functionality for generalising the deriving mechanism in Haskell to arbitrary classes.
This package provides a modular backend for rendering diagrams created with the diagrams embedded domain-specific language (EDSL) to Scalable Vector Graphics (SVG) files.
This package provides a data type These a b which can hold a value of either type or values of each type. This is usually thought of as an "inclusive or" type (contrasting Either a b as "exclusive or") or as an "outer join" type (contrasting (a, b) as "inner join").
data These a b = This a | That b | These a b
Since version 1, this package was split into parts:
https://hackage.haskell.org/package/semialign For
AlignandZiptype-classes.https://hackage.haskell.org/package/semialign-indexed For
SemialignWithIndexclass, providingialignWithandizipWithhttps://hackage.haskell.org/package/these-lens For lens combinators.
http://hackage.haskell.org/package/monad-chronicle For transformers variant of
These.
This library lets you derive automatically Haskell functions that let you query each endpoint of a <http://hackage.haskell.org/package/servant servant> webservice. . See <http://docs.servant.dev/en/stable/tutorial/Client.html the client section of the tutorial>. . <https://github.com/haskell-servant/servant/blob/master/servant-client/CHANGELOG.md CHANGELOG>.
This package provides implementation of the Wagner-Fischer dynamic programming algorithm to find the optimal edit script and cost between two sequences. The implementation in this package is specialised to sequences represented with Data.Vector but is otherwise agnostic to:
The type of values in the vectors;
The type representing edit operations; and
The type representing the cost of operations.
This library provides peek and poke functions for network byte order.
This package provides a data type for colours and transparency. Colours can be blended and composed. Various colour spaces are supported. A module of colour names ("Data.Colour.Names") is provided.
This package provides fast unicode character sets for Haskell, based on complemented PATRICIA tries.
This package profides a class for encoding and decoding UTF8 strings with instances for several common types. It also includes several functions for working with UTF8. It aims to be lightweight, depending only on Base and including only one module.
This Haskell library provides a Template Haskell deriver for unboxed vectors, given a pair of coercion functions to and from some existing type with an Unbox instance.
This Haskell package contains Template Haskell functions for generating functions similar to those in Data.List for tuples of statically known size.
This Haskell package provides interfaces and helper functions for the ghc-persistent package.
This package provides a string interpolation library for Haskell.
This package provides a configuration management library for programs and daemons. The features include:
Automatic, dynamic reloading in response to modifications to configuration files.
A simple, but flexible, configuration language, supporting several of the most commonly needed types of data, along with interpolation of strings from the configuration or the system environment (e.g.
$(HOME)).Subscription-based notification of changes to configuration properties.
An
importdirective allows the configuration of a complex application to be split across several smaller files, or common configuration data to be shared across several applications.
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 package provides functions to marshal and unmarshal pandoc document types to and from Lua. . The values of most types are pushed to pandoc as "userdata" objects that wrap a stable pointer to the Haskell value; these objects come with methods to access and modify their properties. . Sequences are pushed as normal Lua tables, but are augmented with convenience functions.
This package provides types and combinators for linear algebra on free vector spaces.
Efficient hashing-based container types. The containers have been optimized for performance critical use, both in terms of large data quantities and high speed.
This package provides a type called @DMap@ which generalizes @Data.Map.Map@, allowing keys to specify the type of value that can be associated with them.
