结构体类型 type 名字 struct{},下面这段是github.com/urfave/cli包里的代码,声明了一个App的结构体类型
type App struct { // The name of the program. Defaults to path.Base(os.Args[0]) Name string Full name of command for help,defaults to Name HelpName Description of the program. Usage Text to override the USAGE section of help UsageText Description of the program argument format. ArgsUsage Version of the program Version Description of the program Description List of commands to execute Commands []*Command List of flags to parse Flags []Flag }
点操作符也可以和指向结构体的指针一起工作,如果赋给的是个指针,那也可以直接用点来操作
type User struct{
Name string
}
user:=&User{Name:"taoshihan"}
fmt.Println(user.Name)
cliApp := cli.NewApp()
cliApp.Name = "gocron"
cliApp.Usage = "gocron service"
这个cli包下的NewApp方法返回的是*App类型,因此cliApp就是可以直接点操作里面的成员了
return &App{ Name: filepath.Base(os.Args[0]),HelpName: filepath.Base(os.Args["A new cli application",UsageText: ""0.0.0
