Haskell Web Application Interface (WAI)

The Haskell Web Application Interface (WAI) [1] is an effort to standardize the interface between web servers and Haskell web applications or frameworks, to promote web application portability across a variety of web servers. It borrows heavily from Python's successful WSGI [2] standard, which serves the same purpose, and recent interest in writing web applications in Haskell.

Haskell Server Pages - an extension of Haskell for writing dynamic web pages.

Lemmih and nibro have whipped up a HAppS bidning to serve Haskell Server Pages dynamically:


Several additions have been made, in particular to the core server-side functionality. We have introduced a monad transformer, HSPT, which allows us to reuse all the cool HSP functionality with other monads than the standard HSP one (which is now HSPT IO). In particular this allows us to reuse the literal XML generation for EDSLs built on top of HSP, without having to redefine all the heavy XML-generating machinery.

nibro has been working on XHTML-specific generation combinators. Types have been greatly simplified, much thanks to good ideas from Heffalump.

Lemmih has been working on bindings for jQuery for client-side code generation, which will likely use the new cool HSPT stuff.

Generic Information

You can apply for an account and a project using the community server. You can also apply for a project.

Once you have an account and a project, you upload a Darcs repository as follows. First, initialize your repository on the server:

 $ ssh community.haskell.org
 you@haskell:~$ cd /srv/code/yourproject
 you@haskell:/srv/code/yourproject$ darcs init

Then, log out and push your repository:

 $ darcs push community.haskell.org:/srv/code/yourproject
