做个小笔记, 默认情况下,log模块的只打印日期和时间, 没具体行号,比较不爽,嘿嘿
package main
/*
#include <stdlib.h>
*/
import "C"
import "log"
func main() {
log.SetFlags(log.Lshortfile | log.LstdFlags)
log.Println( C.random())
}
打印结果:
2012/07/24 19:27:55 X.cgo1.go:14: 1804289383
其中, log.Lshortfile 还可以设置为log.Llongfile 即完整文件路径
获取当前行数,文件名,函数名(方法名):
package main
import (
"runtime"
"fmt"
)
func main() {
funcName, file, line, ok := runtime.Caller(0)
if ok {
fmt.Println("Func Name=" + runtime.FuncForPC(funcName).Name())
fmt.Printf("file: %s line=%d\n", file, line)
}
}
