setup_shared_value_context

penzai.treescope.handlers.shared_value_postprocessor.setup_shared_value_context() → AbstractContextManager[None]

Returns a context manager for the shared value context.

Within this context manager, _shared_object_ids_seen will refer to a consistent tracker. This tracker can then be used to check for repeated appearances of the same mutable object.

This should be included in the context_builders argument to any renderer that checks for shared values.
