导出的const应该有评论

Question

I'm trying to export a constant from a go like this:

package log

const (
    FATAL = iota // fatal errors
    ERROR = iota // errors might happend
    DEBUG = iota // debug mode
) // const for logging levels

But I'm getting golint error :

exported const FATAL should have comment  (or a comment on this block) or be unexported (golint)

And it's right I'm getting later error in getting access to log.FATAL etc.

Answer 1

Comments for documentation always immediately preceded what they are documenting.

const (
    // FATAL represents fatal errors
    FATAL = iota
