HT-AJAX
HT-AJAX is a small AJAX web framework for Hunchentoot web server that allows transparent calls from Javascript in web pages to the server side Lisp code. It is compatible with Hunchentoot versions prior to 1.0.0.

Note that you might consider using HT-SIMPLE-AJAX, which is is a heavily simplified version of HT-AJAX that lacks some features but works with current versions (> 1.1) of Hunchentoot.

Basically it allows 'exporting' of your lisp functions so that they can be easily called from the Javascript code on your web page. The details of the data transfer can be handled by different backends, or as we'll call them 'AJAX processors'. At the moment three such processors are supported: one simple, built-in, that generates code inside the web page and does not require external libraries. The others are using a javascript library, such as Lokris or Prototype.

The documentation for HT-AJAX library including a small tutorial can be found here.

HT-AJAX is written in Common Lisp and aims to be portable across implementations as well as web browsers. Patches, bug reports, requests and comments are welcome.

HT-AJAX is (supposed to be) ASDF-installable.

The package has found a new home at common-lisp.net, as the author could not be reached anymore. If you _are_ the author, please send email to rt at common dash lisp dot net so that we can get in touch.
