Go는 C/C의 __FILE__ 및 __LINE__ 매크로와 같은 소스 파일 정보에 어떻게 액세스합니까?

import (
    "fmt"
    "runtime"
)

func main() {
    // Get the caller function information
    frames := runtime.Callers(1, 2)

    // Extract the source file name and line number
    fileName, line := getFileInfo(frames[0])
    fmt.Printf("Source file: %s, Line number: %d", fileName, line)
}

// Function to extract file name and line number from caller frame
func getFileInfo(f uintptr) (string, int) {
    // Extract the file name
    frame := runtime.Frame(f)
    return frame.File, frame.Line
}

// Get the caller function information
frames := runtime.Callers(2, 3) // Skip the main function and runtime.Callers

// Extract the source file name and line number
fileName, line := getFileInfo(frames[0])
fmt.Printf("Source file: %s, Line number: %d", fileName, line)
