It is possible to get the file name/path and line number of a given function in Go as follows. |
|||
<lang go>package main |
|||
import ( |
|||
"fmt" |
|||
"path" |
|||
"reflect" |
|||
"runtime" |
|||
) |
|||
func someFunc() { |
|||
fmt.Println("someFunc called") |
|||
} |
|||
func main() { |
|||
pc := reflect.ValueOf(someFunc).Pointer() |
|||
f := runtime.FuncForPC(pc) |
|||
name := f.Name() |
|||
file, line := f.FileLine(pc) |
|||
fmt.Println("Name of function :", name) |
|||
fmt.Println("Name of file :", path.Base(file)) |
|||
fmt.Println("Line number :", line) |
|||
}</lang> |
|||
