Details[edit]

Registry of factory functions to create Config objects. MediaWiki core provides GlobalVarConfig and HashConfig; extensions can create their own implementations of the interface if they wish, although it's typically not needed. The 'main' key must be set, and the value should be a valid callable. It's used for creating the main config object (available as the MainConfig service).
