Connecting a StringToString parameter with viper does not seem work.

[FredrikFolkesson]

Hi.

I am trying to connect a map[string]string parameter to Viper and it does not seem to work.

In my init function I do

cmd.PersistentFlags().StringToString("headers", nil, "Headers to use when connecting..")
viper.BindPFlag("headers", cmd.PersistentFlags().Lookup("headers"))

and then in the cmd function I do

headersMap := viper.GetStringMapString("headers")
//use the headers

The problem seems to be that what is "saved" in Cobra for the value headers is something of the type StringToString and not map[string]string as I would have thought.
(that is the value of the type I get if I do cmd.Flag("headers").Value.Type()

If I save my parameter value by directly specifying the map like this:

cmd.PersistentFlags().StringToStringVar(&headersMap, "headers", nil, "Headers to use when connecting ")

It correctly saves the value in the map. But then I would have to check that the map is not empty and if it is save the value from viper in the map.

I don't know If this is a bug or If I am missing something?

Thanks!

No one?

[micahhausler]

func ToStringMapStringE() doesn't account for pflag's stringToStringValue type.

UPD. wiped my initial text. TLDR: I kinda got the same problem, but actually I was passing arguments the wrong way.
Plus that issue has been just fixed here spf13/viper#608, just 1 week ago!

So the underlying issue was fixed? Going to go ahead and close but feel free to reopen if I misinterpreted.
