The GUI and Tui now present some tasks in grey:
These are “ghost” tasks, they indicate something is that isn’t presently there:
- Waiting tasks that the scheduler hasn’t moved onto yet (i.e. inactive tasks that are waiting).
- Tasks which have been removed (i.e.
cylc remove). - Tasks which have been triggered in the
noneflow, so don’t influence the evolution of the workflow.
They appear in grey, if you click on these tasks, you will see the text “Flows: None”.
This helps to identify waiting active tasks (which aren’t ghosts). These are the tasks which Cylc is currently trying to schedule, but are waiting for something, typically:
- A task prerequisite to be satisfied.
- An xtrigger or ext-trigger to be satisfied.
- Someone to resume them.
