去编程语言括号对样式

Question

I'm just new to learn Go, when I try my first hello world with this style:

func main()
{
      ...somemagic...
}

and the 6g compiler says that's wrong.

But with this style:

func main(){
      ...somemagic...
}

That's OK.

Is the first bracket pair style illegal in Go?

Answer 1

Yes. That's a result of automatic semicolon insertion in Go.

By the way, Go developers format their code using gofmt and follow that formatting.

Answer 2

Yes, the first form can't work because of the semicolon injection rules.
