NetBeans Screenshot of the Week 42: JavaScript Native Interface


At the Roundup last week I talked to
Robert Cooper, who's doing a lot of interesting work with GWT (Google Web Toolkit). In GWT (which compiles Java to JavaScript), you can embed JavaScript directly within the Java files inside comments with special markers. Robert mentioned that IntelliJ has a nice feature for GWT programmers where your native JavaScript snippets get JavaScript highlighting etc.



I figured that would be a trivial thing to add to NetBeans with our language embedding infrastructure. Sure enough, the patch just adds 13 lines of code. Here's a screenshot - showing JavaScript (regular expressions etc) inside Java code (with packages etc) - it's inside comments that start and end with -{ and }-:






If you want this functionality in your own 7.0 build, just download this module nbm, or apply the patch to your own build.
