      !this.done || (!this.done && !this.placeholder)
          ? color[this.color]().underline(this.rendered) : this.rendered
    ].join(` `);

    // Print error
    if (this.error) {
      this.outputError += this.errorMsg.split(`\n`)
          .reduce((a, l, i) => a + `\n${i ? ` ` : figures.pointerSmall} ${color.red().italic(l)}`, ``);
    }

    this.out.write(erase.line + cursor.to(0) + this.outputText + cursor.save + this.outputError + cursor.restore);
