Orion/How Tos/Installing A Plugin

< Orion‎ | How Tos

This page explains how an end-user can install third-party functionality so that it is available to the Orion editor.

Install using Registry Page


  • Enter a plugin URL into the text field. For example, enter to install JavaScript code formatting functionality. Click "Submit".
  • You should see a success message, and the the list will refresh. It should now contain the new plugin.
  • The plugins are currently installed using local storage, which means that they are only active in one browser.

Remove an installed plugin

  • Scroll to the plugin within the list.
  • Click the X, then OK to the prompt.
  • The plugin should disappear from the list.


Using installed functionality

Installed plugins may contribute functionality to Orion in a number of different ways, not all of which are immediately visible in the UI.

Continuing from where the previous example left off:

  • From the Navigator page, create a new JavaScript file called test.js.
  • Click on test.js to open it in the Orion code editor.
  • Type or copy/paste some JavaScript code into the editor (preferably some code with messy formatting).
  • Look at the editor toolbar. You'll see a new command available called "Format JS". This command was contributed by the jsbeautify plugin we installed earlier. Commands can also define a key binding that activates the command. (You can see a list of available key bindings by pressing Shift+Ctrl+? while on the editor page, or Shift+? on any other page.) A contributed editor command has access to the selected text in the editor, the complete editor buffer, and information about the current selection. As a result of invoking a command, the command can replace the current selection with a new text, change the complete editor buffer, and/or change the selection.


  • Select your code, click "Format JS", and it will be formatted for you.

See the Developer Guide for a list of places where new functionality can be contributed to Orion. If you have ideas for an extension but need more or different API to implement it, please file a bug.
