Use unexported variables

The unexported variables

unexport/i.go

  1. package unexport
  3. var i int
  4. func init() {
  5.     i = 2
  6. }

The new variables points the unexported variables

main.go

  1. package main
  3. import (
  4.     "fmt"
  5.     _ "unsafe"
  7.     _ "unexport"
  8. )
  10. //go:linkname I unexport.i
  11. var I int
  13. func main() {
  14.     fmt.Println(I)
  15. }

Use unexported functions

  1. package main
  2. import (
  3.     "fmt"
  4.     "github.com/alangpierce/go-forceexport"
  5. )
  7. func main() {
  8.     var timeNow func() (int64, int32)
  9.     err := forceexport.GetFunc(&timeNow, "time.now")
  10.     if err != nil {
  11.         // Handle errors if you care about name possibly being invalid.
  12.         fmt.Println(err)
  13.     }
  14.     // Calls the actual time.now function.
  15.     sec, nsec := timeNow()
  16.     fmt.Printf("%v %v", sec, nsec)
  17. }
