5.7. Anaconda add-on structure

An Anaconda add-on is a Python package that contains a directory with an __init__.py and other source directories (subpackages). Because Python allows you to import each package name only once, specify a unique name for the package top-level directory. You can use an arbitrary name, because add-ons are loaded regardless of their name - the only requirement is that they must be placed in a specific directory.

The suggested naming convention for add-ons is similar to Java packages or D-Bus service names.

To make the directory name a unique identifier for a Python package, prefix the add-on name with the reversed domain name of your organization, by using underscores (_) instead of dots. For example, com_example_hello_world.

When writing an add-on, ensure the following:

Following is a sample directory structure for an add-on which supports every interface (Kickstart, GUI and TUI):

com_example_hello_world
├─ gui
│  ├─ init.py
│  └─ spokes
│     └─ init.py
└─ tui
   ├─ init.py
   └─ spokes
   └─ init.py

Each package must contain at least one module with an arbitrary name defining the classes that are inherited from one or more classes defined in the API.

You can include a category subpackage if an add-on needs to define a new category, but this is not recommended.
