'Frankenstyle' refers to the naming convention that is used to uniquely identify a Moodle plugin based on the type of plugin and its name.

Martin Dougiamas is credited with inventing the word 'frankenstyle'. (It is a great word!)


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

  • The prefix is determined by the type of plugin. For example, the prefix for a module is mod.
  • The name is the name of the plugin. (Plugin names are always made of lower-case letters.)

So the frankenstyle name for the quiz module is mod_quiz.

Plugin types

  • Activity modules: [mod] => /mod
  • Admin reports: [report] => /admin/report
  • Assignments: [assignment] => /mod/assignment/type
  • Authentication plugins: [auth] => /auth
  • Blocks: [block] => /blocks
  • Course formats: [format] => /course/format
  • Course reports: [coursereport] => /course/report
  • Database field types: [datafield] => /mod/data/field
  • Database presets: [datapreset] => /mod/data/preset
  • Editors: [editor] => /lib/editor
  • Enrolment plugins: [enrol] => /enrol
  • Filters: [filter] => /filter
  • Grade export plugins: [gradeexport] => /grade/export
  • Grade import plugins: [gradeimport] => /grade/import
  • Grade reports: [gradereport] => /grade/report
  • Local plugins: [local] => /local
  • Messaging consumers: [message] => /message/output
  • Mnet services: [mnetservice] => /mnet/service
  • Plagiarism plugins: [plagiarism] => /plagiarism
  • Portfolio plugins: [portfolio] => /portfolio
  • Question behaviours: [qbehaviour] => /question/behaviour
  • Question formats: [qformat] => /question/format
  • Question types: [qtype] => /question/type
  • Quiz reports: [quiz] => /mod/quiz/report
  • Repository plugins: [repository] => /repository
  • SCORM reports: [scormreport] => /mod/scorm/report
  • Themes: [theme] => /theme
  • User profile fields: [profilefield] => /user/profile/field
  • Webservice protocols: [webservice] => /webservice
  • Workshop allocation strategies: [workshopallocation] => /mod/workshop/allocation
  • Workshop evaluation plugins: [workshopeval] => /mod/workshop/eval
  • Workshop grading forms: [workshopform] => /mod/workshop/form

To get a definitive list, do print_object(get_plugin_types()); in a Moodle 2.x install.


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

Other places (TODO)

Please add more as they come up.
