A functional IMAP library would be nice, particularly one that can be used in conjunction with encryption and authentication. References have been found to a SoC project although it appears to be derelict.

We could use a .NET FFI library that lets you easily call into the .NET framework. Perhaps the (abandoned?) [http://galois.com/~sof/hugs98.net/ Hugs .NET FFI library] could be resurrected/updated and ported to GHC? Maybe a tool could even be created that automates the interoperability of Haskell and arbitrary .NET libraries?

* The core HTTP libraries need a lot of work. There is the beginnings of a useful library there, but many http codes are not handled, and there should be simple 'get' and 'head' functionality.

-
* Support for wider Word values in bytestring.

* Adding bytestring support to Parsec.
 
-
* Simple process forking/popen, of type <hask>String -> IO String</hask>, is needed (the implementation should be in base)

Current revision

This page provides a list of missing and found libraries for solving common real world programmer tasks.

If you think there should be a library for some common task, add it to this page, and someone may well step up and write it. If you know of a library to solve an open problem domain, link to it.

Please add your proposals to the Haskell Proposals reddit, which allows voting and commenting on each new project idea.

The first place to look is the full libraries list.


If you have code that improves on something in the base libraries, you might consider submitting it to the libraries process, so it can appear in the standard libraries.

Contents

1 Existing libraries (by problem domain)

See the full libraries list.

1.1 GUIs

See GUI libraries

1.2 High performance string IO

See String libraries

1.3 Binary IO

See Binary IO

1.4 Compression

See Compressing data

1.5 Encryption

See Crypto libraries

1.6 Web frameworks

See Web frameworks

1.7 XML processing

See XML handling

1.8 Database access

See Databases

2 Libraries to package

Several cool libraries are out there, not yet in hackage / cabal format. Some on the hitlist , that would be great to package up would be:

3 C libraries

C libraries are often very popular, and cheap to bind to. A good task would be to just write bindings to C libraries, sorted by popularity.
