Documentation
The Go programming language is an open source project to make programmers more productive.
Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
Getting started
Installing Go
Instructions for downloading and installing Go.
Tutorial: Getting started
A brief Hello, World tutorial to get started. Learn a bit about Go code, tools, packages, and modules.
Tutorial: Create a module
A tutorial of short topics introducing functions, error handling, arrays, maps, unit testing, and compiling.
Learning Go
A Tour of Go
An interactive introduction to Go in three sections. The first section covers basic syntax and data structures; the second discusses methods and interfaces; and the third introduces Go's concurrency primitives. Each section concludes with a few exercises so you can practice what you've learned. You can install it locally with:
$ go get golang.org/x/tour
This will place the tour binary in your workspace's bin directory.
How to write Go code
This doc explains how to develop a simple set of Go packages inside a module,
and it shows how to use the go command
to build and test packages.
Editor plugins and IDEs
A document that summarizes commonly used editor plugins and IDEs with Go support.
Effective Go
A document that gives tips for writing clear, idiomatic Go code. A must read for any new Go programmer. It augments the tour and the language specification, both of which should be read first.
Diagnostics
Summarizes tools and methodologies to diagnose problems in Go programs.
