ENH: A dry-run mode to display all the tasks which will be run. #251
Description
Is your feature request related to a problem?
Users might want to know how many tasks will be executed before actually starting the session. Also for detecting whether @pytask.mark.persist should be applied anywhere.
Describe the solution you'd like
Add another option to build which will trigger a dry-run. At the end you see the usual table and summary with a new outcome type "To be executed" or something like this.
API breaking implications
None.
Describe alternatives you've considered
None.
Additional context
