Description Let's face it: GUIs can only do so much. Sure, they
have their place - they're intuitive and user-friendly - but for
productivity, nothing beats a CLI. Many organizations these days
settle for the GUI, thinking no alternative offers similar
accessibility but better functionality. Does this describe your
organization? Pick up this book and get them to think again.
Building Modern CLI Applications in Go helps you achieve what most
assume isn't possible: an interface that rivals the GUI in elegance
yet surpasses it in high-performance execution. Through its
practical, step-by-step approach, you'll gain 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, giving you full mastery of
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 guide, you'll be fully equipped to take the performance
and flexibility of your organization's applications to the next
level. What you will learn * Explore good CLI philosophy and enact
it effectively using Go * Master Go code structure, testing, and
other essentials * Add a colorful dashboard to your CLI using
engaging ASCII banners * Use Cobra, Viper, and other frameworks to
give your CLI an edge * Handle inputs, API commands, errors, and
timeouts like a pro * Target builds for specific platforms the
right way using build tags * Build with empathy, using easy bug
submission and traceback * Containerize, distribute, and publish
your CLIs quickly and easily Who This Book Is For This book is for
beginner and intermediate Golang developers who have an interest in
developing CLIs and who enjoy learning by doing. You will need to
