Tern: Intelligent JavaScript tooling Demo

Docs Code

Tern is a stand-alone CODE-ANALYSIS ENGINE for JavaScript. It is intended to be used with a code editor plugin to enhance the editor's support for intelligent JavaScript editing. Features provided are: * Autocompletion on variables and properties * Function argument hints * Querying the type of an expression * Finding the definition of something * Automatic refactoring Tern is open-source (MIT license ), written in JavaScript, and capable of running both on node.js and in the

browser .

EDITOR PLUGINS

There is currently Tern support for the following editors:

* Emacs

* Vim

* Sublime Text

* Brackets (built in to the base editor)

* Light Table

* Eclipse (and general Java API)

* TextMate

* SourceLair (built in to the base

editor)

* Chocolat (built in to the base editor) Follow the links to find instructions on how to install the plugins. COMMUNITY AND SUPPORT There is a discussion forum for questions and discussion around Tern. For announcements, such as new releases, there is a low-volume mailing list

.

For reporting bugs, I prefer that you use the github issue tracker

.

Code contributions are welcome, preferably through pull requests

.

DOCUMENTATION

The reference manual should be your first stop for figuring out how to use Tern. If you are interested in the way the system works internally, take a look at this blog post or the video of the talk I gave about it at the Curry On conference.
