This issue seems to be a question about how to use Go, rather than a feature request or defect report about the Go language and/or toolchain.

We have decided that our experiment to allow questions on the issue tracker has not had the outcome we desired, so I am closing this issue. I'm sorry that we can't answer your question here.

There are many other methods to get help if you're still looking for answers:

• The golang-nuts mailing list.

• Stack Overflow, with questions tagged go.

• The Go Forum, a web-based forum hosted by GoBridge.

• The Gophers Slack hosted by GopherAcademy; use the invite app for access.
  The #general channel is a good starting point.

• Go Community on Hashnode with questions and posts tagged with "go"

• IRC channel #go-nuts on Freenode
