For the latest set of ready to use libraries and tools, visit hackage.haskell.org
Standard library
- Haskell's standard library is called the Prelude. It is implicitly imported by default, and includes the most commonly used functions.
Haskell library collections
In increasing order of size:
- Haskell Prelude.
- The Haskell Language and library specification defines basic, portable functionality.
- Changes to these libraries are handled by the Haskell' process.
- The The GHC boot libraries, which come with GHC, are generally an improved and expanded version of the Haskell 98 libraries, in the hierarchical namespace.
- Changes to these libraries are handled by the package maintainer if one exists, or the Library submissions process if not.
- Hoogle - the Haskell API Search Engine - indexes the above libraries
- The Hackage database aims to be a comprehensive a collection of released Haskell packages.
Hackage
New libraries are packaged and distributed via Hackage. Start on Hackage if you are looking for some functionality that did not come installed with the Haskell Platform.
See also Hackage and how to install a Cabal package.
Haskell applications and libraries
Applications, libraries and tools for Haskell or written in Haskell have been classified below, but you should check Hackage for the latest list.
- Audio, music and sound
- Bioinformatics
- Concurrency and parallelism
- Compilers and interpreters
- Compiler construction, lexing, parsing, pretty printing
- Cryptography and hashing
- Data Structures and IO Libraries
- Database interfaces
- Editors written in Haskell and editors for Haskell.
- Extended Haskell
- Games
- Genetic programming
- Graphical User Interface (GUI) Libraries
- Graphics
- Hardware verification
- Linguistics and natural language processing
- Mathematics and physics
- Network
- Operating systems and systems programming (also emulators)
- Program development
- Robots
- Theorem provers
- Tools for interfacing with other languages
- Web, HTML, XML
Other places to look include:
- The Library hierarchy page on this wiki.
- The Haskell community reports.
- The mailing list for discussion of issues related to libraries.
You can also propose and vote on new libraries that you'd like, and look at our past Summer of Code proposals.
Guidelines for developers
Built with Cabal
Developer guides:
- How to write a new Haskell library
- How to propose changes to the standard libraries
- Creating a .deb from a Haskell Cabal package
- Creating a Haskell library by example
- Guide to making standard library submissions
- If you notice the library documentation is lacking, or could be improved, please report it here
- Google Code Search can help identify common idioms, improving your API.
- Future projects, more projects people would like.
- Project activity for some of the larger Haskell projects is graphed here.
- Cabal, The Common Architecture for Building Applications and Libraries, is a framework for packaging, building, and installing any tool developed in the Haskell language.
- Hack-Nix, a set of tools based on the Nix package manager to manage multiple setups to build a project
Proposals for the module name space layout that can be used to guide the construction of new libraries.
Libraries for other languages
If you are thinking about designing a new library for Haskell, you ought to look what has been done in other languages. Here are standard library definitions for
