Making A Collaborative Notepad

[fowlplay4]

This interested me enough to make something "working" the catch is that it's very in-efficient though since it's basically just sending the entire text back and forth instead of determining what's different then sending the only changes instead.

Text isn't stored on the server-side either.

PHP Code:

function onActionServerSide() {
  if (params[0] == "update") {
    for (temp.a: allplayers) {
      if (temp.a == player) continue;
      if (this in temp.a.weapons) {
        temp.a.triggerclient(this.name, "updated", params[1]);
      }
    }
  }
}

//#CLIENTSIDE

function onCreated() {
  new GuiWindowCtrl("Notepad_Window") {
    profile = GuiBlueWindowProfile;
    clientrelative = true;
    clientextent = "559,520";

    canmaximize = false;
    canminimize = false;
    canmove = true;
    canresize = true;
    closequery = false;
    canresize = false;
    destroyonhide = false;
    text = "Online Notepad";
    x = (screenwidth - width) / 2;
    y = 100;

    new GuiScrollCtrl("Notepad_Scroll") {
      profile = GuiBlueScrollProfile;
      height = 494;
      hscrollbar = "dynamic";
      vscrollbar = "dynamic";
      width = 559;
      y = 25;

      new GuiMLTextEditCtrl("Notepad_Multiline") {
        profile = GuiBlueMLTextEditProfile;
        height = 17;
        horizsizing = "width";
        text = "";
        width = 534;
      }
    }
    new GuiTextCtrl("Notepad_Text") {
      profile = GuiBlueTextProfile;
      height = 20;
      text = "Active Collaboration";
      width = 432;
      x = 4;
      y = 2;
    }
  }
}

function onActionClientSide() {
  if (params[0] == "updated") {
    // Save Cursor Position
    temp.old_cursor = Notepad_Multiline.cursorposition;
    // Update Text with Changes
    Notepad_Multiline.text = params[1];
    // Restore Cursor Position
    Notepad_Multiline.cursorposition = temp.old_cursor;
    // Update Last Width and Text
    this.last = Notepad_Multiline.text.length();
    this.last_text = Notepad_Multiline.text;
  }
}

// There is no onTextChanged for GuiMLTextCtrl
// Change in text does cause it be 'Reflowed' though.
function Notepad_Multiline.onReflow() {
  // Check if text has changed
  if (this.last != Notepad_Multiline.text.length()) {
    // Text Changed
    onTextChanged();
    // Update Last Width and Text
    this.last = Notepad_Multiline.text.length();
    this.last_text = Notepad_Multiline.text;
  }
}

// Determine and Handle Changes Here
function onTextChanged() {
  temp.new_text = Notepad_Multiline.text;
  temp.old_text = this.last_text.link();
  triggerserver("gui", name, "update", temp.new_text);
