go get -v github.com/spf13/cobra/cobra
git clone https://golang.org/x/sys
git clone https://golang.org/x/text

//然后出现了错误
[janking@localserver cobra]$ go install ./cobra
../viper/viper.go:38:2: cannot find package "github.com/fsnotify/fsnotify" in any of:
	/usr/lib/golang/src/github.com/fsnotify/fsnotify (from $GOROOT)
	/home/janking/gowork/src/github.com/fsnotify/fsnotify (from $GOPATH)

//我用这个命令没成功，最后还是手动下载压缩包的放在上面错误提醒的相对目录就好了
git clone https://github.com/fsnotify/fsnotify

//进入相应的目录gowork/src/github.com/spf13/cobra/cobra
sudo go install ./cobra

//然后好大的一个坑，出现下列错误
[janking@localserver bin]$ ./cobra init
Error: Rel: can't make /home/janking/gowork/bin relative to 

//创建自己的github项目，然后进入里面创建agenda，在这个文件夹执行下列命令（目录gowork/src/github.com/JankingWon/agenda）
[janking@localserver agenda]$ ../../../../bin/cobra init
Your Cobra application is ready at
/home/janking/gowork/src/github.com/JankingWon/agenda

Give it a try by going there and running `go run main.go`.
Add commands to it by running `cobra add [cmdname]`.

//注册
../../../../bin/cobra add register

老师指导：

修改 register.go, init() 添加：

1
2
> registerCmd.Flags().StringP("user", "u", "Anonymous", "Help message for username")
>

Run 匿名回调函数中修改为：

1
2
3
> username, _ := cmd.Flags().GetString("user")
> fmt.Println("register called by " + username)
>

[janking@localserver agenda]$ ../../../../bin/cobra init
Your Cobra application is ready at
/home/janking/gowork/src/github.com/JankingWon/agenda

Give it a try by going there and running `go run main.go`.
Add commands to it by running `cobra add [cmdname]`.

//然后通过下面的办法添加命令，并修改新生成的[命令].go文件
[janking@localserver agenda]$ ../../../../bin/cobra add [命令]
//接下来就是写代码了
  • 把cobra.out文件放到/gowork/bin里面
  • 删除所有agenda下面所有文件

  • 进入文件夹gopath/src/github.com/[Github用户名]/agenda文件夹

  • 初始化

    [janking@localserver agenda]$ ../../../../bin/cobra init

  • 添加命令

    [janking@localserver agenda]$ ../../../../bin/cobra add [命令]

  • 然后修改cmd下面的[命令].go文件（如register.go)

  • 运行测试自己的命令

    [janking@localserver agenda]$ go run main.go register -u janking

  • 生成可执行文件

    [janking@localserver agenda]$ go build ./

  • 就可以这样执行命令了

    [janking@localserver agenda]$ ./agenda register -u janking

如何用Hexo写博客

在本地Hexo博客的目录下（子目录也行），打开powershell，输入Hexo new “helloworld”, 就可以新建一个空标题（指的是博客文章）和名称（指的是md文件）都为helloworld的md文件了，最好不要自己手动新建一个md文件，最起码对图片插入不友好，后面会提到
