I had started a post highlighting the recent Eclipse PDT 2.0 release but now find myself dropping the post and the Eclipse IDE altogether. Instead, I'll share why I've switched from Eclipse PDT to NetBeans.
During my first attempts, the jQueryWTP patch installer wouldn't run on Mac OS X 10.4.11 at work. The patch wouldn't run on Leopard at home either. Neither the jQueryWTP project nor its SourceForge download page provide Java or WTP version requirements. All screenshots I've seen show installation on Windows. After a lot of flailing, I was eventually able to get the patch installed. Here is an archive of my trials and tribulations.
I recently needed Java 6 to install an Eclipse patch. As you're probably aware, although Apple updated OS X 10.5 Leopard to Java 6 they probably never will provide updates beyond Java 5 for Mac OS X 10.4 Tiger. The good news is that if you're running an Intel-based Mac, you can keep your Java environment up-to-date with SoyLatte, which is part of the OpenJDK BSD-Port project.
Busy schedules, long to do lists, and deadlines make it tough for developers to get familiar with some of the advanced features their tools provide. This is a shame, because some features, like Eclipse Templates, can really reduce coding time and errors.
You already know that Eclipse PDT provides autocompletion and hints for PHP's built in functions. In addition, commenting your code with PHPDoc adds autocompletion and hinting for your application's classes, methods, and variables. If you haven't already discovered, Eclipse PDT also provides autocompletion of PHP's control structures, class definitions, and methods through code templates.
