## 1. dep简介 ##

`dep`是一个golang项目的包管理工具，一般只需要2-3个命令就可以将go依赖包自动下载并归档到`vendor`的目录中。dep官网参考：[https://github.com/golang/dep][https_github.com_golang_dep]

## 2. dep安装 ##

go get -u github.com/golang/dep/cmd/dep

## 3. dep使用 ##

#进入到项目目录
    cd /home/gopath/src/demo
    #dep初始化，初始化配置文件Gopkg.toml
    dep init
    #dep加载依赖包，自动归档到vendor目录
    dep ensure 
    # 最终会生成vendor目录，Gopkg.toml和Gopkg.lock的文件

## 4. dep的配置文件 ##

`Gopkg.toml`记录依赖包列表。

# Gopkg.toml example
    #
    # Refer to https://golang.github.io/dep/docs/Gopkg.toml.html
    # for detailed Gopkg.toml documentation.
    #
    # required = ["github.com/user/thing/cmd/thing"]
    # ignored = ["github.com/user/project/pkgX", "bitbucket.org/user/project/pkgA/pkgY"]
    #
    # [[constraint]]
    #   name = "github.com/user/project"
    #   version = "1.0.0"
    #
    # [[constraint]]
    #   name = "github.com/user/project2"
    #   branch = "dev"
    #   source = "github.com/myfork/project2"
    #
    # [[override]]
    #   name = "github.com/x/y"
    #   version = "2.4.0"
    #
    # [prune]
    #   non-go = false
    #   go-tests = true
    #   unused-packages = true
    
    ignored = ["demo"]
    
    [[constraint]]
      name = "github.com/BurntSushi/toml"
      version = "0.3.0"
    
    [prune]
      go-tests = true
      unused-packages = true

## 5. dep-help ##

更多dep的命令帮助参考`dep`。

$ dep
    Dep is a tool for managing dependencies for Go projects
    
    Usage: "dep [command]"
    
    Commands:
    
      init     Set up a new Go project, or migrate an existing one
      status   Report the status of the project's dependencies
      ensure   Ensure a dependency is safely vendored in the project
      prune    Pruning is now performed automatically by dep ensure.
      version  Show the dep version information
    
    Examples:
      dep init                               set up a new project
      dep ensure                             install the project's dependencies
      dep ensure -update                     update the locked versions of all dependencies
      dep ensure -add github.com/pkg/errors  add a dependency to the project
    
    Use "dep help [command]" for more information about a command.
