Here is a quick timer implementation that you can improve
yourself:
import std.stdio;
import core.thread;
class ChrisTimer : Thread {
private void delegate() funcToRun;
private long timeToWait;
private bool done = false;
private int noSheep;
private Duration howLong;
// We could make any function a parameter to ChrisTimer if
we had a
// constructor like:
// this(void delegate() dg, long ms) {
this(long ms) {
funcToRun = &doSomething;
timeToWait = ms;
howLong = dur!("msecs")(timeToWait);
funcToRun = &doSomething;
super(&run);
}
private void run() {
while (isRunning && !done) {
funcToRun();
sleep(howLong);
}
}
// Example function that is just going to count sheep (up
to 10).
public void doSomething() {
++noSheep;
writeln("Counted ", noSheep, " sheep.");
if (noSheep >= 10) {
done = true;
}
}
} // ChrisThread class
int main(string[] args) {
auto ct = new ChrisTimer(2000);
ct.start();
return 0;
}
Great stuff, thanks for the code example. I feel flattered to
have my own ChrisTimer now. I'll see which implementation is
better suited for the task (vibe.d's setTimer or my own thread
based on your example).
