昨日、Gmailに何通メールが届いたか教えてくれるやつ

( ﾟдﾟ)ﾊｯ! Advent Calendarのネタが付きかけている！！

というわけで、クソアプリ系のネタです。
Gmailに何通メールが届いたか知るのにいちいちクエリ書いて... っていうのも面倒なので、集計してメール送ってもらうようにしました。

function sumally() 
{
  var n = new Date();
  var y = (function(){this.setDate(this.getDate()-1); return this}).call(new Date);
  var today = n.getFullYear() + "-" + (n.getMonth() + 1) + "-" + n.getDate()
  var yesterday = y.getFullYear() + "-" + (y.getMonth() + 1) + "-" + y.getDate()
  var sentCount = 0, receivedCount = 0;

  //Received count
  var receivedSearchQuery = "before:"+today+" after:"+yesterday+" -is:sent";
  var threads = GmailApp.search(receivedSearchQuery, 0, 500);


  for(var i=0; i<threads.length; i++)
  {
    receivedCount = receivedCount + threads[i].getMessageCount();
  }
  GmailApp.sendEmail(getEmailAddress(), "summary: " + yesterday, receivedCount+" received");
  Logger.log(yesterday +" : "+receivedCount+" received");
}

function getEmailAddress() {
  return YOUR_EMAIL_ADDRESS;
}
