Given a function, is it possible to get its name? Say:
func foo() {
}
func GetFunctionName(i interface{}) string {
// ...
}
func main() {
// Will print "name: foo"
fmt.Println("name:", GetFunctionName(foo))
}
I was told that runtime.FuncForPC would help, but I failed to understand how to use it.
Sorry for answering my own question, but I found a solution:
package main
import (
"fmt"
"reflect"
"runtime"
)
func foo() {
}
func GetFunctionName(i interface{}) string {
return runtime.FuncForPC(reflect.ValueOf(i).Pointer()).Name()
}
func main() {
// This will print "name: main.foo"
fmt.Println("name:", GetFunctionName(foo))
}
