Indentation in Go: tabs or spaces?

Question

Is there a standard Google Go coding conventions document somewhere that sets whether tabs or spaces are preferred for indentation in Go source code?

What is the official

Answer 1

The official recommendation is formatting your code with

go fmt

or using the gofmt command directly

gofmt -w .

You can read more about it here on the golang.org blog, or from the Effective go document:

Indentation
We use tabs for indentation and gofmt emits them by default. Use spaces only if you must.
