code organization 代码组织

go 使用一个 workspace 来存储所有相关的 go 代码，workspace 可能包含有不只一个仓库，每个仓库包含若干 package， package 的路径决定了 package 的导入

workspace

workspace 是包含了如下目录的目录

• src contains Go source files,
• pkg contains package objects, and
• bin contains executable commands.

使用 go tool build src 中的代码，然后安装到 bin 和 pkg 目录，src 的子目录包含若干仓库来跟踪源代码的开发。

    outyet                         # command executable
