Returns a time formatted in H:mm if there is an active timer running in Toggl. I use this to add currently running timers to my `tmux-powerline`

toggl.js

#!/usr/bin/env node
var https = require('https');
var options = {
  hostname: 'www.toggl.com',
  path: '/api/v6/time_entries.json',
  headers: {
    'Content-Type': 'application/json'
  },
  auth: "YOUR_API_TOKEN:api_token"
};


var req = https.get(options, function(res) {
  if( res.statusCode != '200' ) {
    return '';
  }
  res.setEncoding('utf8');
  var data = '', i;
  res.on('data', function (chunk) {
    data += chunk;
  });
  res.on('end', function () {
    var diff, minutes, hours;
    try {
      body = JSON.parse(data);
      for(i = 0; i < body.data.length; i++) {
        if( parseInt(body.data[i].duration, 10) < 0 ) {
          diff = (Date.now() / 1000) + parseInt(body.data[i].duration, 10);
          // diff += Date.now() / 1000;
          minutes = Math.floor((diff % 3600) / 60);
          minutes = (minutes < 10 ? '0' : '') + minutes;
          hours = Math.floor(diff / 3600);
          console.log(hours + ':' + minutes);
          process.exit(0);
        }
      }
    }
    catch (ex) {
      return '';
    }
  });
});

req.on('error', function(e) {
  return '';
  // console.log('problem with request: ' + e.message);
});

Do you have an updated version for https://github.com/Lokaltog/powerline? — or does it needs to be updated at all?
