5. Code organization Workspaces The go tool is designed to work with open source code maintained in public repositories. Although you don't need to publish your code, the model for how the environment is set up works the same whether you do or not. Go code must be kept inside a workspace. A workspace is a directory hierarchy with three directories at its root: src contains Go source files organized into packages (one package per directory), pkg contains package objects, and bin contains executable commands. The go tool builds source packages and installs the resulting binaries to the pkg and bin directories. The src subdirectory typically contains multiple version control repositories (such as for Git or Mercurial) that track the development of one or more source packages. To give you an idea of how a workspace looks in practice, here's an example: bin/ hello # command executable outyet # command executable pkg/ linux_amd64/ github.com/golang/example/ stringutil.a # package object src/ github.com/golang/example/ .git/ # Git repository metadata hello/ hello.go # command source outyet/ main.go # command source main_test.go # test source stringutil/ reverse.go # package source reverse_test.go # test source https://golang.org/doc/code.html
6. github.com/golang/example/ stringutil.a # package object src/ github.com/golang/example/ .git/ # Git repository metadata hello/ hello.go # command source outyet/ main.go # command source main_test.go # test source stringutil/ reverse.go # package source reverse_test.go # test source This workspace contains one repository (example) comprising two commands (hello and outyet) and one library (stringutil). A typical workspace would contain many source repositories containing many packages and commands. Most Go programmers keep all their Go source code and dependencies in a single workspace. Commands and libraries are built from different kinds of source packages. We will discuss the distinction later. The GOPATH environment variable The GOPATH environment variable specifies the location of your workspace. It is likely the only environment variable you'll need to set when developing Go code. To get started, create a workspace directory and set GOPATH accordingly. Your workspace can be located wherever you like, but we'll use $HOME/go in this document. Note that this must not be the same path as your Go installation. $ mkdir $HOME/go $ export GOPATH=$HOME/go For convenience, add the workspace's bin subdirectory to your PATH: $ export PATH=$PATH:$GOPATH/bin Package paths https://golang.org/doc/code.html
