This page explains how to write a plugin for Orion. It's intended for developers who want to extend Orion's functionality.

What's a plugin?

A plugin is basically just an HTML file that knows how to connect to the Orion client. A plugin can be hosted on any web server. Plugins are written in HTML and JavaScript.

In order to be useful, a plugin should provide one or more services. When Orion needs a service contributed by a plugin, it loads the plugin inside an IFrame.

Orion currently supports a small set of extension points — service types that plugins can contribute to, in order to customize the client and add more functionality. These include:

  • Commands on the editor toolbar
  • Commands in the navigator view
  • Content assist
  • Syntax highlighting

What you need

Every plugin must include the following JavaScript dependencies:

The easiest way to satisfy these is to get orion-plugin.js, which is a minified file that includes both of them. You can then copy-paste its contents into a <script> tag in your plugin, or load it externally like so:

<script src="orion-plugin.js">
