Question/Feature Proposal: Execute single task + all its dependencies.

[schrockn]

Hey! Thanks again for creating this framework. I'm enjoying using it.

I was curious if you have considered implementing the following function.

Given a graph and a task name, execute all the dependencies leading up to that task and nothing. This could be an option to run_task (which doesn't appear to execute dependencies of the task?) or as its own function.

Is there are existing way of doing this that I'm missing?

If not are you up for a PR? If so, would love some pointer as how you would want this implemented.

Thanks!

Good question; thanks for raising the issue.

My inclination would be to have this be a function that takes a graph & a task name and returns a graph with all irrelevant tasks marked as done. This graph could then be run in any of the usual ways. Having an argument to the run_* functions would mean implementing this functionality all over again in each case.

The mark_as_done_except function comes close to this, but it is not smart about leaving ancestors marked as not done. The easiest thing to do would be to add an optional parameter or create another similar function.

I'd be happy to take a pull request on this!

Thanks
