This release brings new support of Jade Template Engine. NetBeans recognize files with .jade extension and new Jade template file can be created through New File wizard. The Jade template file is located in HTML5 / JavaScript category. The Jade support covers mainly the editor features.


There are examples of coloring Jade Template files.

image: JadeColoring.png

In Options dialog the colors can be altered.

image: JadeColoringOptions.png

The default colors reflects default colors of Html files. Also the colors of html parts comes from the Html editor.

The coloring of plain text comes from html editor support

image: JadeHtmlColoring.png

and coloring of JavaScript parts comes from javascript editor support.

image: JadeJSColoring.png

Code Folding

The logical parts of the template can be folded together.

image: JadeFolding.png

Code Completion

The support provides code completion of html tags, offers css ids and css classes used in the project. Also javascript code completion works on the appropriate places.

image: JadeCC.png


After ENTER, a beginning of the new line is always indented as the previous line. One exception is a new line after the first line of a comment. In such case, the new line indentation is an indentation of the previous line plus 1 to continue with the writing of a comment.

Node.js Support

Support for Node.js has been added. This includes:

  • Configuration of the Node.js executable


  • New project wizard...


  • ...possibly using Express generator


  • Project problems detection


  • Running JS files via Node.js


  • Project specific configuration of Node.js

  • Running any npm script


Node.js Editor

  • Control - hover functionality

When you place the mouse cursor over an runtime module name in require method and press CTRL / Command, then the documentation for the module is displayed.


  • Code Templates to create HTTP server/client: nodehttp/nodenet Issue 254424


Node.js Debugger

  • Projects with configured node.js debug the node.js execution on Debug Project action.

Grunt Support

Existing Grunt support has been improved.

  • Advanced tasks can be run via project's context menu


  • Parameters can be easily specified, if needed


  • Or via context menu of the Grunt file itself; notice that a few last "advanced" targets are remembered


Gulp Support

Support for Gulp has been added, it works exactly the same way as the existing Grunt support. This includes:

  • Configuration of the Gulp executable


  • gulpfile is shown among Important Files


  • Gulp tasks can be assigned to common IDE actions in the Project Properties dialog


  • Any Gulp task can be run via project's context menu


  • Parameters can be easily specified, if needed


  • Or via context menu of the Gulp file itself; notice that a few last "advanced" targets are remembered


  • Gulp output can be reviewed in the Output window


JavaScript Editor

Code Completion

If the code completion is called inside the string of parameter in method of document.getElementsById(), then it is able to offer all used values of ids attributes in the html and css files in the project.


Similarly the code completion offers CSS classes defined in css file inside the string of parameter in method document.getElementsByClassName().


JSDoc support improvements


NetBeans now understand to the @typedef tag for defining custom types. In the example below is defined new type MyContext.Address. The type is mentioned in the parameter definition of createAddress method. As you can see NetBeans recognise the type and it can be marked as occurrence and the usage of the type can be also renamed. Also the '~' is supported.

image: JsDocTypeDefSupport.png

NetBeans displayed the type in the navigator as well.

When NetBeans know the type, it can be used in code completion.

image: JsDocTypeDefSupportCodeCompletion.png


NetBeans are able to precess @callback JSDoc tag. On the example below there is defined a callback Request.requestCallback with two parameters. These callback is used as a parameter of the Request.send method. Matching name of the callback is marked via the mark occurrences functionality and it can be renamed.

image: JsDocCallback01.png

On the picture above is also displayed that the callback is shown in the navigator. It has special icon, static method with circle arrow. This item in navigator navigates into the callback definition.

When you call code completion in the function call that has at least one parameter of a callback type, then NetBeans offers generating the callback function.

image: JsDocCallback02.png

The code completion item of the callback function template has the same icon as in the navigator. After applying the template the generated code looks like on the picture below.

image: JsDocCallback03.png

Other Improvements

Marking optional parameter using Google Compiler Syntax.


Braces formatting

Braces placement options have been added to the Editor/Formatting/JavaScript category in Options. When the code is reformatted, braces in JavaScript sources are placed according to the these settings.

image:Js braces format.png

New PHP project with Symfony2 framework can still be created using sandbox but now also using the Symfony installer:




New Project Wizard

Creating a project with existing sources had several lacks:

  • Not obvious how to set build command for non-makefile project
  • Configure project by build log and build result is tricky.
  • Build result field confuses users.
  • Wizard does not store configure script arguments in project meta data.

New Project Wizard solves the problems above and, as a result, makes pre-build and build steps more clear and understandable.


Pre-Build step can be customized later with the new property tab "Pre-Build" (Accessible from Project Properties -> Build -> Pre-Build).

A new C/C++ sample (HelloCMakeWorld) was added, CMake unmanaged project with the pre-build step.

SVN, Git and Mercurial support in Remote mode

Implemented support for SVN, Git and Mercurial Version Control Systems for remote projects.

Feature allows to use VCS in full remote mode the same way as in a local one. User can customize remote VCS preferences in Tools -> Options -> Team -> Remote Mercurial/Git/Subversion

and in Tools -> Options -> Fonts & Colors -> Remote Mercurial/Git/Subversion


Mixed Development support

Provides editor features like navigation from Java methods to C++ functions when JNI or JNA technologies are used. Makes debugging of mixed applications mostly seamless. Also helps with creation of JNI projects directly from Java classes. Features:

  • Generating an auxiliary C++ JNI project from Java code that allows your Java and C++ code to interact
  • Regenerating JNI header files from Java classes or adding the new ones to the C/C++ existing projects
  • Navigation in editor from Java (JNI or JNA)methods to C++ implementation
  • Fast generating of boilerplate code to access Java classes/methods/fields from the context menu (right click on Java symbol -> Mixed Development). JNI signature of any Java symbol also could be acquired in that way.
  • Debugging both Java and C++ code at once (breakpoints can be placed and will be hit in java and c++ files without the need to adjust a debugger)
  • Step Into action on a Javamethod will switch a debugger to the corresponding c++ function


Edit Properties of Multiple Files

Feature allows user to modify and apply properties for multiple files or folders in the context of the same project.


For example, user wants to change

  • include directories
  • preprocessor definitions
  • whether to exclude the file from code assistance
  • the kind of tool used to compile the file

It can be done now by calling Properties menu item on multiple files (or folders) and modifying properties which are mutual to the selected nodes.

Support Doxygen C++ comments

A number of projects uses a doxygen-style single line "///" comments for documentation. Type "///" in editor and press tab to generate a doxygen-style documentation template.

/// \param argc
/// \param argv
/// \return 
int main(int argc, char** argv) {
    return 0;


Code Folding for compound blocks

Block folding were added to compound statement (if-else, do-while, while, etc).


For example,

if (1) {
} else if (2) {
} else {

can be folded to

if (1) {...3 lines} else if (2) {...3 lines} else {...3 lines}


if (1) {...3 lines} else if (2) {
} else {...3 lines}

Same for all other conditional statements, iteration statements, etc.

Navigating from compiler hint in editor to output log

This feature allows user to navigate from a line with a compiler error/warning in editor to the corresponding line in the build log.

Press Alt+Enter on the line with error and select "Show in Output" item. IDE will find an error line in the output window.


Configure Code Assistance action is added for full remote projects

Added Code Assistance support for full remote projects. Code Assistance wizard lets you specify how your code will be parsed by the built-in parser used for the code assistance features of the IDE.


SendTo Utility

The SendTo utility makes it easier to run any external script on selected files from within the IDE. You can use two types of scripts with SendTo:

  • Scripts that act on selected files
  • Scripts that act on selected text

The utility includes a small set of pre-defined scripts that you can modify to serve your particular needs. You can also add new scripts.


To execute a SendTo script that acts on selected files, do one of the following:

  • Right-click on a file in the Projects window and choose Tools > Send To > script_name
  • Right-click on an open file's tab in the Source Editor and choose Send To > script_name

If the selected script has a validation script, that script is executed first to determine whether the selected script can be applied to the selected files.

To execute a SendTo script that acts on selected text:

  • Select the text in the Source Editor, right-click and choose Send To > script_name

Generate missing switch clauses

The IDE can generate missing case clauses in switch statement, including the default clause.


Experimental lldb-mi support


We've included an lldb-mi support. In order to get NetBeans work with lldb on Mac follow the instruction:

  • Build lldb-mi on Mac (
  • Before starting an IDE init the LLDB_DEBUGSERVER_PATH environment variable with the path to debugserver (it is supplied as a part of command line tools) and export it.
  • To make the IDE use the lldb instruction set add the additional -J-Dcnd.debugger.lldb=true parameter into the NetBeans run command.

Call Graph enhancements

File:Netbeans-cnd-call graph.png

The Call Graph feature was extended:

  • Variables and fields now can be the starting points of graph
  • Icons were added to nodes to distinguish variables from functions
  • Exporting a graph in the text format (GraphML, an XML-based file format for graphs) is now possible
  • If a function is called multiple times from another it's possible to see and navigate to any of these calls instead of the first one only.

New audits and hints
