I am working on an open source personal project called Box . I am currently working on making it easier to add more boxes, both for my self and for others. I have a function in boxes/boxes.go that returns an array with all the different box names. I was wondering if I could use pointers or some other tool to be able to add elements to the array without having to know that the elements exist. eg you write a third-party box and it will add itself to the list of boxes either when you install it or when box is run. I am thinking of using an initialization function, but I am not sure how to implement it. Any help would be highly appreciated.
boxes/boxes.go
package boxes
var Boxes []string
func GetBoxes() *[]string {
return &Boxes
}
Boxes are just strings in this case.
Lets say I have
// SomeFile.go
package new_box
import boxes_package
func AddBox() {
allBoxes := GetBoxes() // returns a pointer
// do some stuff and add "some box" to Boxes from boxes/boxes.go
}
I have tried
func AddBox() {
boxes := GetBoxes()
*boxes = append(*boxes, "some box")
}
and it works but I need to call it somewhere
Answer
package boxes
var Boxes []string
func GetBoxes() *[]string {
return &Boxes
}
func AddBox(name string) bool {
Boxes = append(Boxes, name)
return true
}
and then I just called AddBox in SomeFile.go
