newmetakeys: ClassVar[set] = {'delete', 'emphas', 'insert', 'little', 'strong'}

Meta keys to add to those of the parent class.

Important

Only use this when defining a new Node subclass. When dealing with Node isntances, do not access this attribute directly neither for reading nor writing. Always use metakeys() in that case.

Examples

The keys in newmetakeys are added to the meta keys of the parent class.

>>> nodes.Heading.newmetakeys
{'title'}
>>> nodes.Heading.metakeys() == nodes.Node.metakeys() | {"title"}
True

The intended use, and only supported use, of newmetakeys is at the time of class definition.

>>> class NewNode(nodes.Node):
...     newmetakeys = {"newkey"}
>>> NewNode.metakeys() == nodes.Node.metakeys() | {"newkey"}
True
