Chronos

From WoWDev

Chronos is a function library to make tracking timed tasks and distributed tasks easier.

Download the most recent release version from the curse site or the newest alpha contained in the Cosmos Alpha download. (You will also need Sea)

Example:

Chronos.schedule(10, foo, "a");

Will call foo("a") in 10 seconds.

Note: Do not include () after your function name, which coders tend do to often like Chronos.schedule(10, foo(), "a"); this causes your function to be called immediately and Chronos will try to "call" the return value of your function after the specified interval (which is not neccesarily bad if your function returns a function...)

Chronos.startTimer("SomeID");
foo()
delta = Chronos.endTimer("SomeID");

Will return the amount of time needed to run foo.

Chronos Examples

Chronos.scheduleByName("TEST", 120, bar, "a");
Chronos.scheduleByName("TEST", 12, bar, "a");

Will call bar("a") after 12 seconds (overwriting the first timer).

Chronos.performTask( 
      {
      begin   = function() Sea.io.print("Hello!"); setglobal("a", 0);  end; 
      step    = function() Sea.io.print(getglobal("a")); setglobal("a", getglobal("a")+1); end;
      end     = function() Sea.io.print("Bye!"); end; 
      isDone  = function() return ( getglobal("a") > 50 )  end;
      }
   );

Will print
