This is the stub README.txt for the "smackjack" project.
Smackjack is a small Ajax framework written in Common Lisp. Basically Smackjack allows browser code call lisp functions via ajax and get a return value. The code can be downloaded with all its dependencies and loaded by quicklisp (10/2013).
Currently runs under Hunchentoot web server but there are plans to allow other web servers. It was a fork of ht-simple-ajax and aspires to be a replacement to the unmaintained and out of date ht-ajax.
Differently than those two libraries, this one depends on parenscript to generate client-side javascript and allows greater flexibility in generated javascript.
Current version is compatible with ht-simple-ajax but it lacks many features of ht-ajax.
The following features are addition to those available in ht-simple-ajax:
-
AJAX via Post as well as Get
-
response can be text, xml or json.
-
optional javascript namespaces to encapsulate generated javascript functions.
-
The arguments of the functions can be treated by cl-json before calling the function.
The code also contains a "pusher" subclass. This allows a lisp function call indirectly a javascript function defined in your lisp code by parenscript but runs in the browser. Basically the opposite of SmackJack. This is achieved by adding a simple polling mechanism. Future development may include long polling.
