Ruby Support in the NetBeans IDE: Everything you need in the Edit, Test, Debug Cycle

Powerful Code Editor Code-completion In-place API documentation Syntax highlighting Mark occurrences Go to declaration Instant Rename Semantic syntax highlighting shows method calls, unused variables, etc. http://wiki.netbeans.org/wiki/view/RubyEditing

Live Code Templates ife<tab> if condition else end Abbreviations that expand into snippets of code when the Tab key is pressed after typing the snippet name in the editor. Most of the TextMate snippets have been converted into NetBeans code teampates. http://wiki.netbeans.org/wiki/view/RubyCodeTemplates Most TextMate snippets included

Project and Code Generators Generate Models, Controllers ... Skip or Overwrite existing files Preview Only Option Usage provided in dialog Choose what to generate and how to deal with conflicts Usage for each generator is displayed right there in the dialog The output of the code generator is shown in the Output window. The output is also process such that you can click directly on created files, skipped files, and so on to bring them up in the source editor.

Database Migrations

RHTML Editing <li>Syntax highlighting</li> <li>Code completion</li> You get highlighting of both the HTML and the RHTML directives, as well as the embedded Ruby code. You can jump between actions and views using the “Goto Action/View” item, which is available in the context menu for both Ruby and RHTML files, as well as bound to Ctrl-Shift-A (Command-Shift-A on the Mac). <li>Goto Action/View</li>

Server Integration WEBrick automatically started Server console window Mongrel also supported WEBrick, the built-in Ruby web server, is automatically started when the project is Run (if not already running). The WEBrick console window shows the output of the web server. It will list the requests as they are processed. You can use the Mongrel server as well; just install it via the Gem Manager With Rails, there is no deployment step – the application is deployed in place. If you hit Run File, NetBeans will try to open the browser on a more specific page; for example, the page corresponding to the controller you are editing
