⚠️ Tern.java is now OUTDATED, it's recommended to use Eclipse Wild Web Developer instead

tern.java

tern.js is a stand-alone code-analysis engine for JavaScript written in Javascript.

tern.java provides the capability to use tern.js with Java context. It provides several tern server implementation :

• tern.server.j2v8 wraps tern.js with Java code by using J2V8 to create a Tern Server with Java code.
• tern.server.rhino wraps tern.js with Java code by using Rhino to create a Tern Server with Java code.
• tern.server.nashorn wraps tern.js with Java code by using Java 8 Nashorn JavaScript engine to create a Tern Server with Java code.
• tern.server.nodejs wraps tern.js with Java code by using node.js 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 demo, you will see contentassist available for JavaScript :

Eclipse IDE
