ATF (Eclipse)

Ajax Toolkit Framework is an incubator project within the Eclipse Web Tools Project. It is also a pluggable framework for other AJAX tools. It provides Javascript syntax checking, server deployment, Mozilla embedding, runtime tools such as XHR Monitor, and a debugger based on Mozilla Spidermonkey, JSD, and the Eclipse debug UI. Eclipse integration provides access to existing plugins like ant, subclipse for SVN, server development tools, etc. AJAX "Personalities" provide the potential for tighter integration with Dojo and other toolkits, although so far very little has been done in this area.

There's visual Javascript validation built into ATF. It includes both basic syntax validation and optionally Jslint validation for less obvious potential syntax problems. It works just like MS Word as-you-type spellchecking and Eclipse as-you-type Java validation - as you type if you make a syntax error (or just do something somewhat sloppy) you'll get a red or yellow squiggly under the warning/error and an explanation in the margin. A background task will run validation against all files and place markers in the code such that you can see errors across a project.



You can download and use ATF and its prerequisite Eclipse components (Eclipse SDK, WTP, EMF, GEF, JEM, xulrunner) and choose to use all of ATF or just install the "javascript" feature which implements this validation.



Note - you have to fetch and manually install jslint.js, Dojo and xulrunner due to Eclipse policies - make sure to read the ATF readme to get the full functionality of ATF.
