How to use the event-stream.readArray function in event-stream

function parse(phrase, langs, input, expectedDate, done) {
  function callback(err, data) {
    expect(data).to.have.length(3);
    expect(data[1].data.result.test).to.equalDate(expectedDate);
    expect(data[1].data.result.test).to.equalTime(expectedDate);
    done(null, data[1].data);
  }
  var parser = new lacona.Parser();
  parser.sentences = [phrase()];
  parser.langs = langs;

  es.readArray([input])
    .pipe(parser)
    .pipe(es.writeArray(callback));
}

header: function (block) {
        es.readArray([
          ''
        ].map(function (str) {
          return block.indent + str;
        })).pipe(block);
      }
    }))

function pipeTemplate(block, template) {
        eventStream.readArray([
            template
        ].map(function (str) {
            return block.indent + str;
