An options builder for gulp-newer that understands the output of gulp-hash

example.js

function newerOptionsForHashSuffixedFiles(dest, ext) {
  var re = new RegExp('\\' + ext + '$');
  var replacement = '-[^-]*' + ext;
  return {
    dest: dest,
    ext: ext,
    map: function(src) {
      var d = join(process.cwd(), dest, src);
      d = d.replace(re, replacement);
      var result = glob.sync(d);
      if (result.length === 0) {
        return '';
      }
      if (result.length === 1) {
        return join(dirname(src), basename(result[0]));
      }
      var newest = null;
      for (var i = 0; i < result.length; i += 1) {
        try {
          var stat = fs.statSync(result[i]);
        } catch (e) {
          continue;
        }
        if (newest === null || result[newest].mtime < stat.mtime) {
          newest = i;
        }
      }
      return join(dirname(src), basename(result[newest]));
