• 下图是用cli创建的示例程序gogo的帮助显示：

  

一个hello的例子

package main

import (
    "github.com/mkideal/cli"
)

type argT struct {
    Help bool   `cli:"!h,help" usage:"display help information"`
    Name string `cli:"name" usage:"your name" dft:"world"`
    Age  uint8  `cli:"a,age" usage:"your age" dft:"100"`
}

func main() {
    cli.Run(&argT{}, func(ctx *cli.Context) error {
        argv := ctx.Argv().(*argT)
        if argv.Help {
            ctx.String(ctx.Usage())
        } else {
            ctx.String("Hello, %s! Your age is %d?\n", argv.Name, argv.Age)
        }
        return nil
    })
}
