ve.ui.mwMetaDialogPageFactory

Factory for the pages of ve.ui.MWMetaDialog, including its built-in ones.

Registered classes extend OO.ui.PageLayout and are constructed with ( name, config ). Pages appear in the dialog in registration order, so the built-in ones are ordered by where their files sit in the module's script list.

A page may declare:

• static.modes: the surface modes it applies to, e.g. [ 'source' ]. Unset means all modes.

and may implement:

• setup( fragment, config ): prepare the page, optionally returning a promise.
• teardown( { action } ): apply or discard changes, per the action that closed the dialog.
• getFieldsets(): the fieldsets whose widgets the dialog watches for changes.
• isValid(): whether the page's settings are valid, as a boolean or a promise for one.

The built-in pages edit the document and are staged with it; a contributed page applies its own changes on 'done' instead, and discards them otherwise.
