Actions should have a way to determine the what triggered them

pgier opened this issue · comments

AFAICT there is currently no way to determine which flag triggered an action from within the action function itself. This makes it difficult to re-use an action function between multiple flags. It would be nice if either the context contained the particular flag that called the action, or if there was a second parameter which contained this information.
