## 16 Naming Conventions

See Tips and Conventions, for a description of Emacs Lisp programming conventions. These conventions help ensure that Emacs packages work nicely one another, so an EIEIO-based program should follow them. Here are some conventions that apply specifically to EIEIO-based programs:

- Come up with a package prefix that is relatively short. Prefix all classes, and methods with your prefix. This is a standard convention for functions and variables in Emacs.
- Do not prefix method names with the class name. All methods in EIEIO are “virtual”, and are dynamically dispatched. Anyone can override your methods at any time. Your methods should be prefixed with your package name.
- Do not prefix slots in your class. The slots are always locally scoped to your class, and need no prefixing.
- If your library inherits from other libraries of classes, you must “require” that library with the `require` command.
