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.

Who is this book for?

This book is for beginner- and intermediate-level Golang developers who take an interest in developing CLIs and enjoy learning by doing. You’ll need an understanding of basic Golang programming concepts, but will require no prior knowledge of CLI design and development. This book helps you join a community of CLI developers and distribute within the popular Homebrew package management tool.

What you will learn

Disclaimer, I received a free copy of the book for this review.This book is an excellent resource for anyone interested in developing command-line applications using Go. The book offers clear explanations, practical examples, and hands-on exercises that make it easy for beginners and experienced developers alike to grasp the concepts. With its comprehensive approach and valuable insights, this book is a must-have for anyone seeking to build high-quality CLI applications. Highly recommended!

Kishore Jun 19, 2023

This book has enough examples to understand CLI applications using Go language. For the Beginner it would take a bit to understand initially but one who understands the the pace then it would be easier to gear up with the Author’s perceptive.The book offers detailed explanations, and hands-on exercises that make it easy for beginners to advanced.Marian did a great job in breaking down, complex topics into detailed examples along with hands-on exercises.Overall, I recommend this book!

Henrique Vicente May 17, 2023

Disclaimer: I have many years of experience writing CLI tools and know the author from conferences.In this book, Marian put out an excellent work that will undoubtedly help people looking for a practical guide on developing and distributing a CLI tool using Go.I have many years of experience writing CLI tools using Go, and it was enjoyable to read this book as I got to think about different points of view on topics such as human interaction and also learn some stuff that I am used to doing differently, or haven't done much (such as TUI - text-based user interface).Suggestions for future reviews:* Add a section on code signing in the chapter about releasing* A glossary might help (example: what is man page)* Where the Kubernetes compiler is mentioned, maybe another simpler tool (more accessible for new developers to relate to) could be mentioned instead* I find Cobra the right choice for this book and for most people starting with CLIs, but adding a few examples using the standard library would be neat to show what to do when you need just something simple

POE May 11, 2023

Go use continues to increase, especially in the area of command line interfaces. The author’s experience shines through as you learn CLI standards and structures, frameworks, and more. A methodical approach is taken that starts with technical requirements, includes user input and interactions, and processing data.Additional topics include platform-specific considerations, exception handling, design patterns, and special sections featuring Homebrew and GoReleaser.Great resource!
