Expandable controls

yex.control.Expandable(is_long=False, is_outer=False, from_human=True, name=None, doc=None, *args, **kwargs)

Bases: yex.control.control.Control

When you run an expandable control, it does nothing except create more tokens.

Expandable controls include all macros, and some control flow primitives:

Identifier	Class	Description
\chardef	Chardef
\countdef	Countdef
\dimendef	Dimendef
\macro	Macro	Any macro defined using \def.
\mathchardef	Mathchardef
\muskipdef	Muskipdef
\registerdef	Registerdef
\skipdef	Skipdef
\toksdef	Toksdef
