Source Maps Support

Web client JavaScript debugger and node.js debugger is using generated source maps to allow debugging in the original source files.

Pin Watches

Watches may not only be shown in Variables/Watches window, but also be pinned into an editor area.

When you hover your mouse over a variable or a selection, a tooltip with it' s value is shown. The tooltip now contains a pin icon, which when clicked, creat es a watch pinned into the editor.


The pin watch window is displayed instead of the tooltip. It's location can be adjusted by dragging with a mouse.


The watch updates it's value like a watch in the watches window, but in addition to that, it keeps the last known value, even after the debugging session finishes.

The pin watch window contains two icons on the right side: comment icon and close icon. Clicking on the comment icon shows a text field where you can place comments about this particular watch.


When the pin watch displays structured values, it shows an expansion icon on the left side. When expanded, a view with it's children is shown:


Variables/Watches window does not show the watches that are pinned into the editor by default, but it's possible to view them there as well, via "Show Pinned Watches" context action.


Java Profiler

SQL Queries Profiling

New profiling mode SQL Queries has been added to enable profiling calls from Java processes to databases using a JDBC connection. The profiler displays live list of executed SQL queries with times and execution counts, including the invocation paths. Filtering based on statement type, command type and related tables is available. The collected data can be saved to a snapshot for offline analysis.


Colored Profiling Results

The profiler now enables coloring profiling results based on user-defined filters. This is especially useful for SQL profiling to visually filter out Java EE frameworks calls by displaying their results in gray, but can be used for any other frameworks and user classes. The defined filters can be also easily added to results filters or instrumentation filters.




This release brings mainly support of ECMAScript 6 and selected features of ECMAScript Next. The all basic new features from ECMAScript 6 are supported now as well as major features of ECMAScript Next. There is also basic support for JSX.

ECMAScript 6 Support


In navigator window the generator is marked with '*' badge.


Example, when the generator is defined as private and priviliged methods.


Generator as private and priviliged methods


Generator as a class method


NetBeans offers code completion with documentation for Generators. You can see on the following pictures code completion for generator methods like 'next', 'return' and 'throw'. Also offer property 'done' and 'value' of the result object that is returned from the 'next' method.

Image:Generator-Next.png Image:Generator-Return.png Image:Generator-Throw.png Image:Generator-Next.done.png Image:Generator-Next.Value.png

Shorthand Property Names

NetBeans now understands to shorthand property names in object initializers.

First example shows that the IDE knows about the properties of object 'o' and that the property 'c' is a object with its properties. NetBeans offer the right properties of 'o.c', user can simple refactor the properties etc.


The next example shows that NetBeans understands to new possible written way of method names


and also understands the computed property names. The computed property names are not offered in cc and are not displayed in the navigator.



NetBeans is able to handle constants, display in navigator, code completion etc.


Template Literals

NetBeans is able to handle template literals. Also there is implemented support of the javascript expressions inside template literals. In these expressions works everything as usual (code completion, mark occurrences, go to declaration, etc.).


New Number Literals

ECMA Script 6 brings new hexa, binary and octal literals. NetBeans mark these literals with bold gray letter x, b and o. This can be changed in editor options. Also NetBeans offers code completion for these literals.


String Literals and RegExp Literals

This is not ECMA6 Script specific feature, but now NetBeans offer code completion after string and regexp literals.

Destructuring Assignment

Simple Array Destructuring Assignment


Array Destructuring Assignment with Default Values


Array Destructuring Assignment from a Function


Swap values of two variables


Simple Object Destructuring Assignment


Object Destructuring Assignment without a Declaration

Image:ObjectDestructuringAssignment02.png Image:ObjectDestructuringAssignment03.png

Object Destructuring Assignment, when a property is not defined


Object destructuring assignment to new variable names


Setting a function parameter's default value


Supporting Modules

NetBeans now understands the modules according ECMA6 Script specification. The picture below shows that user also can navigate to the file from which are imported objects and properties.


Object Property Assignment

NetBeans are able to handle creating properties through Object.assign() method as is shown on the picture below.


Default Parameter Values

NetBeans handles default parameter values and use it to obtain information about the type of the parameter as is displayed on the pictures below.

Image:DefaultParams01.png Image:DefaultParams02.png

Block Scope Declarations

NetBeans handles block scope declarations of functions and variables.

Image:BlockScopeFunction.png Image:BlockScopeVariables.png

ECMAScript Next Support

NetBeans now supports the major features of ECMAScript Next aka ECMAScript 7 or 2016. Note the ECMA spec is in draft mode and may change after the NetBeans release.

You can configure project to be ECMAScript 7.


There is a helpful hint notifying about ECMAScript 7 features being used in project configured to ECMAScript 6 or even ECMAScript 5.


Async Functions

Async functions are properly parsed and async and await is colored as being keyword.


Trailing Commas in Function Parameter Lists and Calls

Trailing commas are allowed as described in specification.


Rest/Spread Properties

Rest and spread operator is allowed even for object properties.


Class and Property Decorators

Decorators on class and properties is handled including occurence marking and navigation.


Class Property Declarations

Property declarations inside class body is handled and properly displayed in navigator.


Exponentiation Operator and Standard Library

Exponentiation operator is parsed ok and NetBeans also offers new features of standard library which met the stage 4 of specification:

  • Array.prototype.includes
  • Object.values/Object.entries
  • String.prototype.padStart/String.prototype.padEnd
  • Object.getOwnPropertyDescriptors

JSX Support

The big thing is JSX is now properly parsed and colored in the editor.


Node.js Support

Because NetBeans 8.2 is able to parse code written in ECMA Script 6, NetBeans is also able to parse source files of Node.js 4.0 and newer versions. This means better editor support.

Return Statement in Global Context

ECMA Script specification doesn't allow to use return statement in global context. Node.js sources often use it and NetBeans reports it as error. NetBeans 8.2 are able detect a Node.js source and parse such source file even if there is a return statement in global context. The source has start on the first line with shebang, contains node and has to be at least 12 characters long.



The formatter was enhanced and allows to specify maximum number blank lines for class and object body and array initializer.



UI for Run/Debug launchers is a file located in nbproject and used to manage Run/Debug command configurations.

Now it's possible to manage these configurations using the new UI. To open the configuration window click "Manage Launchers..." from a project's context menu.


After you create necessary launchers you will be able to select how to Run or Debug your project from it's context menu.


Modifying a PATH var: prepending or appending a toolchain path

Some users experienced a problem when a toolchain directory was unconditionally prepended to the PATH variable (e.g. when user's build system uses some tools from /usr/bin, including cross-compiler).


New option in Project Properties -> Build allows to specify if this addition is needed. By default the $TOOLS_PATH will be prepended, but you can change this in Options -> C/C++ -> Build tools -> ...


Auto-detection of correct compiler used by user's build system

Sometimes user's build system uses the custom toolchain, which was not detected automatically by NetBeans. In case the real compiler doesn't match to the active one, code model can cause unexpected to user results.

When creating a project with existing sources you will be suggested to create a toolchain with the real compiler in case it doesn't match to any existing.


Env variable in text fields

You can use environment variables when creating a project with existing sources or project from binary.


Build analyzer based on tool collection wrapper

IDE creates a tool collection wrapper on Windows and Mac.


The wrapper is used to build project. As result all compile command lines are stored and used for configure code assistance.


Terminal extensions

Open Files in Editor from terminal

Simply type "ideopen file1 file2..." and IDE will open specified files in Editor. It's even more useful feature in case you are using a Remote Terminal.


Shortcuts support

Terminal is able to

  • Switch tabs using Alt+1 .. Alt+0
  • Open new tabs with Ctrl+Alt+Shift+T shortcut (by default)

It's a convenient way to work with tabs keyboard only.

Allow terminal to open hyperlinks

Terminal able to open links to files with absolute paths now. You can print a hyperlink in terminal with an escape sequence. Example of such sequence: fprintf(stdout, "(\033]10;%s;%s\007)]\n", "/home/ilia/NetBeansProjects/CppApplication_48/main.cpp:20", "main.cpp:20"); where :lineNumber is optional.

Search in terminal

Search feature is implemented in Terminal now. You can lookup previous (Shift + F3) and next (F3, Enter) occurrences, close the Find Bar with (ESC).


Pin Watches

Watches may not only be shown in Variables/Watches window, but also be pinned into an editor area.

See more in Java Pin Watches description.
