bluesky.preprocessors.finalize_wrapper¶

bluesky.preprocessors.finalize_wrapper(plan, final_plan, *, pause_for_debug=False)[source]¶

try…finally helper

Run the first plan and then the second. If any of the messages raise an error in the RunEngine (or otherwise), the second plan will attempted to be run anyway.

See contingency_wrapper() for a more complex and more feature-complete error-handling preprocessor.

Parameters

planiterable or iterator: a generator, list, or similar containing Msg objects
final_plancallable, iterable or iterator: a generator, list, or similar containing Msg objects or a callable that reurns one; attempted to be run no matter what happens in the first plan
pause_for_debugbool, optional: If the plan should pause before running the clean final_plan in the case of an Exception. This is intended as a debugging tool only.

Yields

msgMsg: messages from plan until it terminates or an error is raised, then messages from final_plan
