Programming in Go : creating applications for the 21st century Upplaga 1

Your Hands-On Guide to Go, the Revolutionary New Language Designed for Concurrency, Multicore Hardware, and Programmer Convenience Todays most exciting new programming language, Go, is designed from the ground up to help you easily leverage all the power of todays multicore hardware. With this guide, pioneering Go programmer Mark Summerfield shows how to write code that takes full advantage of Gos breakthrough features and idioms. Both a tutorial and a language reference, Programming in Go brings together all the knowledge you need to evaluate Go, think in Go, and write high-performance software with Go. Summerfield presents multiple idiom comparisons showing exactly how Go improves upon older languages, calling special attention to Gos key innovations. Along the way, he explains everything from the absolute basics through Gos lock-free channel-based concurrency and its flexible and unusual duck-typing type-safe approach to object-orientation. Throughout, Summerfields approach is thoroughly practical. Each chapter offers multiple live code examples designed to encourage experimentation and help you quickly develop mastery. Wherever possible, complete programs and packages are presented to provide realistic use cases, as well as exercises. Coverage includes Quickly getting and installing Go, and building and running Go programs Exploring Gos syntax, features, and extensive standard library Programming Boolean values, expressions, and numeric types Creating, comparing, indexing, slicing, and formatting strings Understanding Gos highly efficient built-in collection types: slices and maps Using Go as a procedural programming language Discovering Gos unusual and flexible approach to object orientation Mastering Gos unique, simple, and natural approach to fine-grained concurrency Reading and writing binary, text, JSON, and XML files Importing and using standard library packages, custom packages, and third-party packages Creating, documenting, unit testing, and benchmarking custom packages
