We use the import keyword to import a package.įmt is a built-in package provided by Go that provides input/output utility functions. The main package is the entry point of the program and identifies an executable program. go file first declares which package it is part of.Ī package can be composed by multiple files, or just one file. In there, create a hello.go file (you can name it as you want). In there, create a new folder, for example call it hello. Maybe you have a folder in your home directory where you keep all your coding projects and tests. So we’ll do that first, and then we’ll explain how we did it. It’s a programmer's tradition to make the first program print the “Hello, World!” string to the terminal when it’s run. Now we’re ready to create our first Go program! This extension will make your life easier, as it provides IntelliSense (syntax highlighting, autocompletion, on hover information, error highlighting…) and other things like auto formatting, menu options to install packages, testing, and more. At the bare minimum, install the Go extension. Read Go in Visual Studio Code for a quick “up and running” setup. I recommend using Visual Studio Code (aka VS Code) as your editor. On Linux you will have to add the Go binaries folder to your terminal path before you can run the go command after unpackaging the Linux package to /usr/local/go with this command: echo 'export PATH=$PATH:/usr/local/go/bin' > $HOME/.profile This will make it easier to update later. On a Mac you might also want to install Go via Homebrew using brew install golang. The Windows and Mac installers will set the Go binaries path automatically. On Windows, it will be under C:\Program Files\go. On macOS, it’s under /usr/local/go, with binaries in /usr/local/go/bin. The exact location of the Go installation files will depend on your Operating System. NOTE: you might have to open a new terminal before you can run the program, as the installer added the Go binaries folder to the path. Open the terminal and run go version and you should see something like this: Displaying the Go version you have Run the installer, and at the end of the process you will have the go command available in your terminal: Welcome to the Go installer Successful installation modal Go to and download the package for your Operating System.
