## README

__⚠️ Tern.java is now OUTDATED, it's recommended to use [Eclipse Wild Web Developer](https://github.com/eclipse/wildwebdeveloper) instead__

[![Build Status](https://secure.travis-ci.org/angelozerr/tern.java.png)](http://travis-ci.org/angelozerr/tern.java)

[tern.js](https://github.com/marijnh/tern) is a stand-alone code-analysis engine for JavaScript written in Javascript.

[tern.java](https://github.com/angelozerr/tern.java) provides the capability to use 
[tern.js](https://github.com/marijnh/tern) with Java context. It provides several tern server implementation : 

 * [tern.server.j2v8](https://github.com/angelozerr/tern.java/tree/master/core/tern.server.j2v8) wraps tern.js with Java code by using [J2V8](https://github.com/eclipsesource/J2V8) to create a Tern Server with Java code.
 * [tern.server.rhino](https://github.com/angelozerr/tern.java/tree/master/core/tern.server.rhino) wraps tern.js with Java code by using [Rhino](https://developer.mozilla.org/en-US/docs/Rhino)  to create a Tern Server with Java code.
 * [tern.server.nashorn](https://github.com/angelozerr/tern.java/tree/master/core/tern.server.nashorn) wraps tern.js with Java code by using [Java 8 Nashorn JavaScript engine](https://blogs.oracle.com/nashorn/)  to create a Tern Server with Java code. 
 * [tern.server.nodejs](https://github.com/angelozerr/tern.java/tree/master/core/tern.server.nodejs) wraps tern.js with Java code by using [node.js](http://nodejs.org/) to create a Tern Server with Java code. 

As  Tern is *very* CPU and memory intensive, the implementation with Rhino is very slow when JavaScript document is big. So it's better to use node.js or javv8. Nashorn is a little slow compare to J2V8 or node.js 

## Core Features

Once that Tern Server is created with Java using `core` module, 
you can use it in any Java context (Eclipse, Netbeans, etc). 
tern.java provides the capability to use Tern Server with SWT : 

 * contentassist which uses tern.java. If you start the SWT [TernEditor](https://github.com/angelozerr/tern.java/blob/master/eclipse/tern.eclipse.swt.samples/src/tern/eclipse/swt/samples/rhino/RhinoTernEditor.java) demo, 
you will see contentassist available for JavaScript :

## Eclipse IDE

On top of `core` module
Tern.java provides an Eclipse IDE integration with Tern. For more information please read [Tern Eclipse IDE](https://github.com/angelozerr/tern.java/wiki/Tern-Eclipse-IDE).

To install Tern IDE, please read [Installation - Update site](https://github.com/angelozerr/tern.java/wiki/Installation-Update-Site) section.

### Plugins based on Tern IDE

 * [AngularJS Eclipse](https://github.com/angelozerr/angularjs-eclipse) to give support for [AngularJS](https://angularjs.org/).
 * [JavaScript Build Eclipse](https://github.com/angelozerr/jsbuild-eclipse) to give support for [Grunt](http://gruntjs.com/) and [Gulp](http://gulpjs.com/).
