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.

Remote packages


One of the tools that is shipped with Go allows programmers to retrieve packages directly from remote source code repositories. Go, by default, readily supports integration with version control systems including the following:

Note

In order for Go to pull package source code from a remote repository, you must have a client for that version control system installed as a command on your operating system's execution path. Under the cover, Go launches the client to interact with the source code repository server.

The get command-line tool allows programmers to retrieve remote packages using a fully qualified project path as the import path for the package. Once the package is downloaded, it can be imported for use in local source files. For instance, if you wanted to include one of the packages from the Ohm's Law example...
