Double dash for keyword flags vs single dash for character flags about cli

[dufferzafar]

Hmm, this sounds like the correct way to do it. 👍

This is fairly standard in Unix, I think, but in Go it's very common to use a single dash for command line arguments, e.g. go test -run=MyTestName. @codegangsta Do you know if anyone has written up anything about idioms in the Go ecosystem for this sort of thing?

I know that the flags package accepts both -- and - for each given flag. I assume this is for practical reasons. Whether someone types --help or -help, the basic assumption is that the user wants see the help.

We are at the mercy of the underlying flag parsing library on this one, but I agree that it could be something considered if we ever shifted away to our own parser.
