How to extract registered information?

I'm using Cobra in my Golang application. How can I get the list of commands and values that I have registered with Cobra?

If I add a root command and then a "DisplayName" command:

var Name = "sample_"
var rootCmd = &cobra.Command{Use: "Use help to find out more options"}
rootCmd.AddCommand(cmd.DisplayNameCommand(Name))

Will I be able to know what is the value in Name from within my program by using some Cobra function? Ideally I want to access this value in Name and use it for checking some logic.

You can use the value stored in the Name variable for performing operations within your program. An example usage of cobra is:

var Name = "sample_"

var rootCmd = &cobra.Command{
    Use:   "hello",
    Short: "Example short description",
    Run:   func(cmd *cobra.Command, args []string) {
        // Do Stuff Here
    },
}

var echoCmd = &cobra.Command{
    Use:   "echo",
    Short: "Echo description",
    Run:   func(cmd *cobra.Command, args []string) {
        fmt.Printf("hello %s", Name)
    },
}

func init() {
    rootCmd.AddCommand(echoCmd)
}

func Execute() {
    if err := rootCmd.Execute(); err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
}

`

In the above code, you can see that hello is the root command and echo is a sub command. If you do hello echo, it'll echo the value sample_ which is stored in the Name variable.

You can also do something like this:

var echoCmd = &cobra.Command{
    Use:   "echo",
    Short: "Echo description",
    Run:   func(cmd *cobra.Command, args []string) {
        // Perform some logical operations
        if Name == "sample_" {
            fmt.Printf("hello %s", Name)
        } else {
            fmt.Println("Name did not match")
        }
    },
}
