A propos du livre

Présentation de l'éditeur

Go was created by Robert Griesemer, Rob Pike, and Ken Thompson to be an expressive and efficient language for writing readable and robust programs. Since its announcement in 2009, users of traditional, compiled languages have found Go’s simplicity, high-quality libraries, and straightforward tools to be a refreshing change. Go has also been winning converts from users of dynamic languages–those who appreciate how its lightweight type system makes their code safer and faster.

 

The Go Programming Language is the authoritative resource for any programmer who wants to learn Go quickly and effectively. It assumes no prior knowledge of Go nor prior experience with any specific language, so it provides a solid foundation whether your previous experience is with JavaScript, Ruby, Python, Java, or C++. This guide will show you how to write efficient and idiomatic Go, making good use of its standard libraries to solve real-world problems.

• The first chapter is a tutorial on the basic constructs of Go, introduced through example programs for file I/O and text processing, simple graphics, and web clients and servers.
• Early chapters cover the structural elements of a Go program: its syntax, basic and composite data types, functions, and error handling. The examples illustrate many standard packages, how to create new ones, and how to build, test, and manage projects using the go tool.
• The chapters on methods and interfaces introduce Go’s unusual approach to object-oriented programming, including the key principles of encapsulation and composition, as well as Go’s distinctive notion of implicitly satisfied interfaces.
• Two chapters on concurrency present in-depth approaches to this important topic. The first covers the basic mechanisms of goroutines and channels and the style of communicating sequential processes for which Go is renowned. The second covers more traditional aspects of using concurrency with shared variables. These chapters assume no prior knowledge of concurrency, so they provide an excellent tutorial for programmers who would like to understand it better.
• The final two chapters explore lower-level features of Go. One covers the art of metaprogramming using reflection. The other shows how to use the unsafe package to step outside the type system in a controlled way for special situations, and how to use the cgo tool to create Go bindings for C libraries.

The book features hundreds of interesting and practical examples of idiomatic Go code that cover the whole language, its most important libraries, and a wide range of applications. Source code will be freely available for download from the book's companion website (upon publication) and may be conveniently fetched, built, and installed using the go get command.

Présentation de l'éditeur

The Go Programming Language is the authoritative resource for any programmer who wants to learn Go. It shows how to write clear and idiomatic Go to solve real-world problems. The book does not assume prior knowledge of Go nor experience with any specific language, so you’ll find it accessible whether you’re most comfortable with JavaScript, Ruby, Python, Java, or C++.

• The first chapter is a tutorial on the basic concepts of Go, introduced through programs for file I/O and text processing, simple graphics, and web clients and servers.
• Early chapters cover the structural elements of Go programs: syntax, control flow, data types, and the organization of a program into packages, files, and functions. The examples illustrate many packages from the standard library and show how to create new ones of your own. Later chapters explain the package mechanism in more detail, and how to build, test, and maintain projects using the go tool.
• The chapters on methods and interfaces introduce Go’s unconventional approach to object-oriented programming, in which methods can be declared on any type and interfaces are implicitly satisfied. They explain the key principles of encapsulation, composition, and substitutability using realistic examples.
• Two chapters on concurrency present in-depth approaches to this increasingly important topic. The first, which covers the basic mechanisms of goroutines and channels, illustrates the style known as communicating sequential processes for which Go is renowned. The second covers more traditional aspects of concurrency with shared variables. These chapters provide a solid foundation for programmers encountering concurrency for the first time.
• The final two chapters explore lower-level features of Go. One covers the art of metaprogramming using reflection. The other shows how to use the unsafe package to step outside the type system for special situations, and how to use the cgo tool to create Go bindings for C libraries.

The book features hundreds of interesting and practical examples of well-written Go code that cover the whole language, its most important packages, and a wide range of applications. Each chapter has exercises to test your understanding and explore extensions and alternatives. Source code is freely available for download from http://gopl.io/ and may be conveniently fetched, built, and installed using the go get command.
