CLI或TUI程序相关

• flag替代库,命令行参数解析 github.com/spf13/pflag
  支持短标记,-i=123 –i=123相同

     var name int
    var str string
    var fl float64
    var bl bool
    pflag.IntVarP(&name, "name", "i", 123, "int类型")
    pflag.StringVarP(&str, "str", "s", "字符串", "字符串")
    pflag.Float64VarP(&fl, "fl", "f", 3.12, "浮点数")
    pflag.BoolVarP(&bl, "b", "b", true, "布尔")
    pflag.Parse()
    fmt.Println(name, str, fl, bl)

• 配置管理库支持json/toml/yaml github.com/spf13/viper

    viper.SetConfigFile("1.toml") //设置文件路径
    viper.Set("ver", 1.343)
    viper.Set("qq", "9999")
    err := viper.WriteConfig() //写入配置
    if err != nil {
        fmt.Println(err)
    }
  
    err = viper.ReadInConfig() //读取配置
    if err != nil {
        return
    }
    ver := viper.Get("ver") //查找配置
    fmt.Println("ver:", ver)

• 终端颜色 github.com/fatih/color

  color.Red("红色")
   color.Blue("蓝色")
   color.Green("绿色")
   color.Yellow("黄色")
   color.Cyan("天蓝")
   color.Magenta("紫色")
   color.New(color.BgBlue, color.FgHiRed, color.Bold).Add(color.Underline).Println("背景蓝色,前置红色")

• spf13 github.com/spf13/cobra

  cobra-cli init --license MIT
  cobra-cli add go 添加功能
  隐藏默认的自动完成
  rootCmd.CompletionOptions.HiddenDefaultCmd = true
  rootCmd.Version = "1.0.0"
  rootCmd.PersistentFlags() 用于全局标志
  rootCmd.Flags() 用于当前命令标志

• 获取系统语言 github.com/Xuanwo/go-locale

lang, _ := locale.Detect()
    fmt.Println(lang.String())
    zh-CN,zh-HK,en-US

• 进度条 github.com/schollz/progressbar

req, _ := http.NewRequest("GET", "https://dl.google.com/go/go1.14.2.src.tar.gz", nil)
resp, _ := http.DefaultClient.Do(req)
defer resp.Body.Close()

f, _ := os.OpenFile("go1.14.2.src.tar.gz", os.O_CREATE|os.O_WRONLY, 0644)
defer f.Close()

bar := progressbar.DefaultBytes(
    resp.ContentLength,
    "downloading",
)
io.Copy(io.MultiWriter(f, bar), resp.Body)

• 创建图标和托盘菜单
