[go-nuts] json.Marshal() doens't have access to lowercase struct members - any way around this?

Hi,

I'm trying to use the above program but I don't quite understand why part of
if isn't working - relative noob :)

The aim is to use json.Marshal to get a json string representation, but it
needs to have the lowercase var names, protocol, domain, etc of the Referrer
struct in the json string.

Doing the .Marshal call produces and empty Referrer, which seems to be due
to the lowercase var names in the Referrer type - which I know are non
exportable, but didn't think that would happen on a struct.

Is there any way of getting these lower case names in to the json string?

Thanks in advance,
Mat

Just use tags to instruct the json.Marshal to use lowercase names for the
generated JSON: http://golang.org/pkg/encoding/json/#Marshal
