Learning Go Programming

Overview of this book

The Go programming language has firmly established itself as a favorite for building complex and scalable system applications. Go offers a direct and practical approach to programming that let programmers write correct and predictable code using concurrency idioms and a full-featured standard library. This is a step-by-step, practical guide full of real world examples to help you get started with Go in no time at all. We start off by understanding the fundamentals of Go, followed by a detailed description of the Go data types, program structures and Maps. After this, you learn how to use Go concurrency idioms to avoid pitfalls and create programs that are exact in expected behavior. Next, you will be familiarized with the tools and libraries that are available in Go for writing and exercising tests, benchmarking, and code coverage. Finally, you will be able to utilize some of the most important features of GO such as, Network Programming and OS integration to build efficient applications. All the concepts are explained in a crisp and concise manner and by the end of this book; you would be able to create highly efficient programs that you can deploy over cloud.

Preface

Building packages


The Go tools reduce the complexity of compiling your code by applying certain conventions and sensible defaults. Although a full discussion of Go's build tool is beyond the scope of this section (or chapter), it is useful to understand the purpose and use of the build and install tools. In general, the use of the build and install tools is as follows:

$> go build [<package import path>]

The import path can be explicitly provided or omitted altogether. The build tool accepts the import path expressed as either fully qualified or relative paths. Given a properly setup workspace, the following are all equivalent ways to compile package volt, from the earlier example:

$> cd $GOPATH/src/github.com/vladimirvivien/learning-go
$> go build ./ch06/volt

$> cd $GOPATH/src/github.com/vladimirvivien/learning-go/ch06
$> go build ./volt

$> cd $GOPATH/src/github.com/vladimirvivien/learning-go/ch06/volt
$> go build .

$> cd $GOPATH...
