Hints

How can you speed up Eclipse?

Eclipse Distributions

You can get Nodeclipse plugin in any Eclipse-based IDE. Recommended are standard Eclipse distributions or Nodeclipse NTS for Windows (where it is already pre-installed).

Adobe Flex Builder

Nodeclipse runs perfectly well inside Adobe Flex Builder

Aptana Studio

Aptana Studio hints are now on separate page Hints-Aptana.md

Nodeclipse & Enide Studio

Nodeclipse NTS is Eclipse distribution. Nodeclipse NTS currently is only for Windows.

Select JVM for Eclipse instance

Add -vm option in eclipse.ini, that is in Eclipse folder. Quote:

Note the format of the -vm option - it is important to be exact:
	The -vm option and its value (the path) must be on separate lines.
	The value must be the full absolute or relative path to the Java executable, not just to the Java home directory.
	The -vm option must occur before the -vmargs option, since everything after -vmargs is passed directly to the JVM. 

Example:

...
-vm
C:\Program Files\Java\jdk1.7.0_11\bin\javaw.exe
-vmargs
-Xms40m
-Xmx512m

Using jvm.dll is advised to be faster:

-vm
C:\Program Files\Java\jdk1.7.0_11\jre\bin\server\jvm.dll

Editors

JavaScript Editors

In Eclipse ecosystem there are a lot of JavaScript Editors. Some examples:

• JSDT project
• VJET project
• Nodeclipse ships with it's own Node Editor and ...
• JS Editor (from Chromium project)

JavaScript Code Assist

Eclipse standard JavaScript Development Tools (JSDT) (wiki) already includes JavaScript Editor with Code/Content Assist function.

Go to Preferences->JavaScript->Editor->Content Assist

Inferred Types

In order for some JDT-based functionality (such as code completion) to work correctly, class type information needs to be available. This information is not available in JavaScript, but it can be inferred in many cases.

Code assist for some libraries and framework is provided as extensions, for example Code assist for jQuery.

CoffeeScript Editor

Check http://coffeescript.org/ for intro about CoffeeScript.

	# Assignment:
	number   = 42
	opposite = true
	
	# Conditions:
	number = -42 if opposite
	
	# Functions:
	square = (x) -> x * x
	
	# Arrays:
	list = [1, 2, 3, 4, 5]
	
	# Objects:
	math =
	  root:   Math.sqrt
	  square: square
	  cube:   (x) -> x * square x
	
	# Splats:
	race = (winner, runners...) ->
	  print winner, runners
	
	# Existence:
	alert "I knew it!" if elvis?
	
	# Array comprehensions:
	cubes = (math.cube num for num in list)

Use CoffeeScriptSet.p2f to quickly install.
Warning: this plugin created by Adam Schmideg was not updated for a year. see About CoffeeScript support in Nodeclipse

JSON Editor

JSON means JavaScript Object Notation, so you just have to have any JavaScript editor and associate the *.json files with it (this is default since Nodeclipse 0.4):

Window > Preferences
General > Editors > File Associations
Add... > File type: *.json
Select *.json file type > Add... (Associated editors) > JavaScript Editor
Make it default

Now you can now open JSON files with the JavaScript editor (with syntax highlight), use the formatter and set your favorite color theme with Eclipse Color Theme.

Alternatively, if you need/like good Outline, you can install JSON Editor plugin.

Editor Minimap

There is experimental support for minimap.

(Only in Nodeclipse NTS, close when don't like)

Launch npm

1. (Switch to Node perspective)

2. run as -> npm....

See also npm documentation

Thank to George Pang for question.

Quick Search

Press Ctrl+Shift+L to open QuickSearch Dailog, where you can search anything anywhere superquick.

Start Explorer or Shell

Right-click folder in Project Explorer or selected path in an Editor, then

Git

Press Ctrl+Shift+3 to commit current file or file set.

Update several Git repositories at once

Just select them with mouse (holding Ctrl)
Right-click any of them Team -> Pull
See result.

Conflict resolution

When pulling, EGit (as any Git) does fetch then merge.
EGit will show error message if change conflict has happened. And Merging will stop.

You can use Team -> Synchronize, to compare local git workspace and with git repository.

Then you may select Replace With -> Branch, Tag, or Reference...

GitHub Flavored Markdown (GFM) Viewer

See markdown .md files as they are on GitHub. Very useful when browsing node_modules folder. Minimum recommended version is 1.1.1 .

To open GFM View right click any .md file and select Show in GFM view. (Since 1.1.1 in Enide 0.4.10)

Connect Eclipse to GitHub issues

STS comes with EGit and GitHub support, that includes Mylyn GitHub Connector.

You need to add at least 1 query
