dart 控制台应用程序中的 Ctrl+c

Is there a way to catch CTRL+C in dart console application?

For example, press CTRL+C to send clean "closing" packet to web socket clients from server instead of just brutally closing the sockets.

现在可用

我在以下位置找到了以下测试代码统一差异：tests/standalone/io/signals_test_script.dart https://codereview.chromium.org/119093007/patch/120001/130013

import "dart:io";

void main(args) {
  int usr1Count = int.parse(args[0]);
  int usr2Count = int.parse(args[1]);
  var sub1;
  var sub2;
  void check() {
    if (usr1Count < 0 || usr2Count < 0) exit(1);
    if (usr1Count == 0 && usr2Count == 0) {
      sub1.cancel();
      sub2.cancel();
    }
    print("ready");
  }
  sub1 = ProcessSignal.SIGUSR1.watch().listen((signal) {
    if (signal != ProcessSignal.SIGUSR1) exit(1);
    usr1Count--;
    check();
  });
  sub2 = ProcessSignal.SIGUSR2.watch().listen((signal) {
    if (signal != ProcessSignal.SIGUSR2) exit(1);
    usr2Count--;
    check();
  });
  check();
}

希望这很快就会发布。
