Editing NetBeans (section)

==Integrated modules==
These modules are part of the NetBeans IDE:

===NetBeans Profiler===
The '''NetBeans Profiler'''<ref>{{cite web

 | title      = Profiler
 | publisher  = Netbeans.org
 | access-date = 2008-05-17}}</ref> is a tool for the monitoring of Java applications: It helps developers find [[memory leak]]s and optimize speed. Formerly downloaded separately, it is integrated into the core IDE since version 6.0.
The [[Profiler (computer science)|Profiler]] is based on a Sun Laboratories research project that was named JFluid. That research uncovered specific techniques that can be used to lower the overhead of profiling a Java application. One of those techniques is dynamic bytecode instrumentation, which is particularly useful for profiling large Java applications. Using dynamic bytecode instrumentation and additional algorithms, the NetBeans Profiler is able to obtain runtime information on applications that are too large or complex for other profilers. NetBeans also support Profiling Points that let developers profile precise points of execution and measure execution time.

===GUI design tool===

Formerly known as ''project Matisse'', the [[Graphical user interface builder|GUI design]]-tool enables developers to [[Graphical user interface builder|prototype and design]] [[Swing (Java)|Swing]] [[Graphical user interface|GUIs]] by dragging and positioning GUI components.<ref>{{cite web

The GUI builder has built-in support for JSR 295 (Beans Binding technology), but the support for JSR 296 ([[Swing Application Framework]]) was removed in 7.1.

===NetBeans JavaScript editor===
The NetBeans JavaScript editor provides extended support for [[JavaScript]], Ajax, and [[CSS]].<ref>{{cite web

JavaScript editor features comprise [[syntax highlighting]], [[Code refactoring|refactoring]], [[Autocomplete|code completion]] for native objects and functions, generation of JavaScript class skeletons, generation of [[Ajax (programming)|Ajax]] [[Callback (computer science)|callbacks]] from a template; and automatic [[JavaScript#Compatibility considerations|browser compatibility]] checks.

CSS editor features comprise [[Autocomplete|code completion]] for styles names, quick navigation through the navigator panel, displaying the CSS rule declaration in a List View and file structure in a Tree View, sorting the outline view by name, type or declaration order (List & Tree), creating rule declarations (Tree only), refactoring a part of a rule name (Tree only).

The NetBeans 7.4 and later uses the new [[Nashorn (JavaScript engine)|Nashorn JavaScript engine]] developed by Oracle.
