  glob(pattern, function (err, files) {   
    if (err) {
      throw new Error(err);
    }
    files.forEach(f => {
      var contents = fs.readFileSync(f).toString();
      var res = parser(contents);
      results = results.concat(res);
    });
   
    cb && cb(results);
  });
}

// demo 
runner(null, function (res) {

  var locale = {};

  res.forEach(r => {
    locale[r.id] = r.defaultMessage;
  });


  var locales = {
    en: locale,  
  };
