Suppose I have a function that tests for some condition, e.g. (define current-user (make-parameter #f)) (define (current-user-set?) (not (false? (current-user)))
What is the best way to say "wait until 'current-user-set?' returns true"? I've been through the Events chapter in the Reference and nothing seems like a great fit. I could do polling via sleep or alarm-evt but that seems inefficient. Is there a better way? -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
