Developing extensions

An extension is just a subdirectory in the extensions directory.

Web ui interacts with installed extensions in the following way:

• extension's scripts in the scripts directory are executed as if they were just usual user scripts, except:
  • sys.path is extended to include the extension directory, so you can import anything in it without worrying
  • you can use scripts.basedir() to get the current extension's directory (since user can name it anything he wants)
• extension's javascript files in the javascript directory are added to the page
• extension's style.css file is added to the page

For how to develop custom scripts, which usually will do most of extension's work, see Developing custom scripts.
