The Go programming language comes with a rich toolchain that makes obtaining packages and building executables incredibly easy. One of Go’s most powerful features is the ability to cross-build executables for any Go-supported foreign platform. This makes testing and packaging your software easy and accessible.
Функция с переменным количеством аргументов — это функция, которая принимает ноль, одно или больше значений в качестве одного аргумента. Хотя функции с переменным количеством аргументов встречаются редко, их можно использовать, чтобы сделать код более чистым и удобным для…
This book is designed to introduce you to writing programs with the Go programming language. You’ll learn how to write useful tools and applications that can run on remote servers, or local Windows, macOS, and Linux systems for development.
Methods are Go functions that operate on instances of a specific type. Methods allow you to communicate not only what the data is, but also how that data should be used. Methods are the core concept that makes Go interfaces possible.
In this tutorial you’ll explore various ways to use the `flag` package to build different kinds of command-line utilities. You’ll use a flag to control program output, introduce positional arguments where you mix flags and other data, and then implement sub-commands.
Um código robusto precisa reagir de forma correta a circunstâncias inesperadas, como erros de entrada do usuário, problemas de conexões de rede e falhas de discos. Tratamento de erro é o processo de identificar quando seu programa se encontra em um estado inesperado e adotar medidas para…
This Go tutorial will go over the basics of working with strings, including how to create and print strings, concatenate and replicate strings, and store strings in variables.
Este artículo le servirá como guía para comprender GOPATH, su funcionamiento y su configuración. Este paso es crucial para configurar un entorno de desarrollo de Go, así como para comprender cómo se ubican, instalan y construyen archivos de origen en Go. En este artículo,…
When communicating more complicated error information to your users, or to your future self when debugging, sometimes these two mechanisms are not enough to adequately capture and report what has happened. To convey this more complex error information we can implement the standard library interface type, `error`, to get more functionality.
Many Go modules are open-source, which means they can be freely accessed and used. However, sometimes you need to make a module private. In this tutorial, you will publish a private Go module, set up authentication to access a private module, and use a private Go module in a project.
