# pointer [](https://pkg.go.dev/github.com/carlmjohnson/pointer) Some generic Go pointer helpers: ```go // Start with a null pointer var strptr *string // pointer.Deref safely dereferences a nil pointer into its empty value fmt.Println(pointer.Deref(strptr) == "") // prints true // pointer.Coalesce lets us specify a default value for a nil pointer fmt.Println(pointer.Coalesce(strptr, "hello, world")) // prints "hello, world" // We can create a pointer to a string or other primitive type with pointer.New newptr := pointer.New("meaning of life") // takes a pointer to a string, wow! // pointer.First returns the first pointer that isn't nil. strptr = pointer.First(strptr, newptr) // returns newptr ```
