In my current project I am trying to write a logging function that will conditionally call fmt.Println.
My current Log function looks like this:
func Log(level int, a ...interface{}) {
if level <= LogLevel {
fmt.Println(a)
}
}
But when I call it like this the output of Log gets encased in brackets for some reason:
http://play.golang.org/p/Aa8vC54Ih0
package main
import "fmt"
var LogLevel int
func main() {
fmt.Println("string", 10, 3.1415926)
LogLevel = 1
Log(1, "string", 10, 3.1415926)
}
func Log(level int, a ...interface{}) {
if level <= LogLevel {
fmt.Println(a)
}
}
string 10 3.1415926
[string 10 3.1415926]
This to me looks like the a argument in Log gets transformed somehow. How would I go about to pass a to fmt.Println in a way that is identical to calling fmt.Println directly?
