Implementation
There's a JavaScript implementation written in Common-Lisp in Mozilla at http://lxr.mozilla.org/mozilla/source/js2/semantics/.
Generating JavaScript Code
-
Parenscript is Javascript with Lisp syntax and macros.
- jsgen is a similar package with a more direct mapping to JavaScript.
- parse-js is a simple ECMAScript 3 parser
Talking to JavaScript
JavaScript is also needed to implement the client-side part of AJAX (Asynchronous JavaScript And XML)-- a Common-Lisp implementation of which can be found as CL-AJAX for araneida and HT-AJAX for Hunchentoot.If XML seems too heavy-weight one can use cl-json or st-json to directly send JSON (Java Script Object Notation).
