I have see this:
func (c *Command) AddCommand(cmds ...*Command) {
but what does this mean?
I assume:
- function name
AddCommand
- Input Parameters: ?
- Return type: ?
Same question for:
func (c *Command) Execute() error {
I have see this:

AddCommand
Same question for:
func (c *Command) Execute() error {
c* Comand is a pointer to Command type and it is pointer receiver. That means you can call ths function like this
c = &Command{}
c.AddCommand(…)
cmds… *Comabds means that this function receives any number of Command pointer parameters.
it is called variadic function
For example
var c1, c2, c2 *Command
c1 := &Command{}
c2 = &Command{}
c3 = new(Command)
c1.AddCommand(c2,c3)
– or –
c1.AddCommand(c2)
– or –
c1.AddCommand(c1, c2, c3)
There is no return type in this function
In your last question, the function return an error and use a *Command as a receiver.
