'Frankenstyle component names' refers to the naming convention that is used to uniquely identify a Moodle plugin based on the type of plugin and its name. They are used throughout the Moodle code (with a notable exception being the css class names in the themes).

Martin Dougiamas invented the word 'frankenstyle' to describe this naming system which was invented by Petr Skoda.


Frankenstyle component names have a prefix and then a folder name, separated by an underscore.

  1. The prefix is determined by the type of plugin. For example, the prefix for an activity module is mod.
  2. The name is the folder name of the plugin, always lower case. For example, the name for Quiz is quiz.

So the frankenstyle component name for the quiz module is mod_quiz.

To get a definitive list in your version of Moodle 2.x, use a small Moodle script with print_object(get_plugin_types());.


Frankenstyle is used in:

Table names

All table names for a plugin must begin with its frankenstyle name (after the standard Moodle table prefix).

Examples: mdl_mod_quiz, mdl_mod_quiz_attempts


All capabilities for a plugin use the frankenstyle name, except with a / instead of a _.

Example: mod/quiz:viewattempt

Language files

The main language file for each plugin (with the notable exception of activity modules) is the frankenstyle component name.

Examples: /blocks/participants/lang/en/block_participants.php

Other places (TODO)

Please add more as they come up.
