As part of the Eclipse University Outreach initiative, I have developed plug-ins that allow students to evaluate Scheme and Prolog in Eclipse. A beta version of the Scheme plug-ins is now available. After resolving some licensing issues, the Prolog beta version should be available in June. You can view the user guides here for both to get a feel for what they can do. You can also download the Scheme plug-ins from the same location. Next up will be a lite version for Java.
