jug shell subcommand opens up a shell within the environment of the
Jugfile. It can be used for debugging and exploration of the task structure.
Inside the environment, you can use the
value(task) function to load
results (if available; otherwise, an exception is thrown).
invalidate(task) function invalidates the results of its argument and
all dependents, recursively, much like the
jug invalidate subcommand.
You can call methods on
Task objects directly as well:
run(): run the task and return the result even if the task has run before.
can_run(): whether all dependencies are available
can_load(): whether the task has already run
invalidate(): remove the result of this task (not recursive, unlike the
invalidatesubcommand, unlike the invalidate function).
You can access the original function with the
.f attribute as well.
