Applications and libraries
(Redirected from Libraries and tools)
Applications, libraries and tools written in Haskell.
Developers: if you release any Haskell code, please document it for the community, by adding it to the appropriate category on this page.
1 Haskell libraries
The first places to look for data types or functions are:
- The Haskell 98 Prelude
- Haskell 98 Language and library specification
- The Haskell Hierarchical Libraries bundled with Haskell implementations
- Hoogle - the Haskell API Search Engine, indexing the above libraries
- The Hackage database - a collection of released Haskell packages
See also Hackage and how to install a Cabal package.
2 Hackage
Since 2006, new libraries are packaged and distributed from Hackage
Start on Hackage if looking for a library not in the standard.
- Developers: you can upload your cabalised packages to hackage (if you don't have a login, just ask).

4 Guidelines for developers
Developer guides:
- How to write a new Haskell library
- 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
- Wanted libraries: if you can't find a library for a problem, document it here, and someone might write it.
- 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.
Proposals for the module name space layout that can be used to guide the construction of new libraries.
5 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
