Evolve the humble CLI using Go and unleash the next generation of powerful, flexible, and empathy-driven interfaces Purchase of the print or Kindle book includes a free PDF eBook Key FeaturesDiscover how Go enables the development of elegant and intuitive CLIsExplore a range of CLI development aspects and pick up a vast array of best practicesCreate engaging and user-friendly interfaces and learn how to distribute themBook Description Although graphical user interfaces (GUIs) are intuitive and user-friendly, nothing beats a command-line interface (CLI) when it comes to productivity. Many organizations settle for a GUI without searching for alternatives that offer better accessibility and functionality. If this describes your organization, then pick up this book and get them to rethink that decision. Building Modern CLI Applications in Go will help you achieve an interface that rivals a GUI in elegance yet surpasses it in high-performance execution. Through its practical, step-by-step approach, you'll learn everything you need to harness the power and simplicity of the Go language to build CLI applications that revolutionize the way you work. After a primer on CLI standards and Go, you'll be launched into tool design and proper framework use for true development proficiency. The book then moves on to all things CLI, helping you master everything from arguments and flags to errors and API calls. Later, you'll dive into the nuances of empathic development so that you can ensure the best UX possible, before you finish up with build tags, cross-compilation, and container-based distribution. By the end of this UX book, you'll be fully equipped to take the performance and flexibility of your organization's applications to the next level.
