- 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
