quick dream chrome extension: shorten tab names in busy windows

background.js

// Also probably need a background page with tab permissions: https://developer.chrome.com/extensions/tabs
//  listening for onCreated, onUpdated and do a 
chrome.tabs.onCreated.addListener(tabCreated);
  
function tabCreated(tab) {
  chrome.tabs.query({"windowId": tab.windowId}, function (tabList) {
    tablist.forEach(function (aTab) {
      aTab.sendMessage({"numTabs": tabList.size()}); 
    })
  })
}

// And do similar for tabUpdated to get it to change the new title
// As a stretch goal you could make it revert the change for the active tab

content_script.js

// This is a content_script: https://developer.chrome.com/extensions/content_scripts

// probably need to do something like
chrome.runtime.onMessage.addListener(maybeShorten)

function maybeShorten(msg) {
  if (msg.numTabs > 10) {
    document.originalTitle = document.title;
    document.title = shortenTitle(document.title);
  } else {
    document.title = document.originalTitle;
  }
}
// Should replace things like:
//   "Issues · termie/php-oauth-reference"
// with
//   "I·t/p-o-r"
function shortenTitle(s) {
  s1 = s.replace(/(\w)\w+/g, "$1");
  s2 = s1.replace(/\s*([^\s\w]+)\s*/g, "$1"));
  return s2;
}
