Every - return true every N cycles or S seconds
for (0..200)
{
print_stats() if every(20); # every 20 cycles
print_times() if every(seconds => 5); # every 5 or more seconds
sleep 3;
}
Returns true every $number times it's called, or every time $number seconds have elapsed since the last time it was called. The every() function keeps track of where it was called by line, even if you call it twice on the same line, e.g. print "hello" if every(5) or every(6); The every() function will use the Devel::Callsite module to find the opcode and interpreter context (both unique numbers).
Returns true when the conditions (cycles or seconds elapsed) are met. Thanks to Dr.Ruud on comp.lang.perl.misc for helping with this idea, and to Jerry Hedden for cleaning it up. Thanks to Ben Morrow for getting Devel::Callsite started, which module is essential to Every.
