go - How to get the directory of the currently running file?

Question

In nodejs I use __dirname . What is the equivalent of this in Golang?

I have googled and found out this article http://andrewbrookins.com/tech/golang-get-directory-of-the-current-file/ . Where he uses below code

_, filename, _, _ := runtime.Caller(1)
f, err := os.Open(path.Join(path.Dir(filename), "data.csv"))

But is it the right way or idiomatic way to do in Golang?
