PageTemplate.engine

Chameleon’s expression engine factory for this template’s expression types.

PageTemplate.engine: Callable[[], ExpressionEngine]

Used by code that evaluates expressions dynamically, such as ExpressionEvaluator(template.engine, builtins) in z3c.pt for path() and exists() inside python: expressions. chameleon-rs compiles the template itself natively and doesn’t use it.
