Can't use struct from own package

Question

I created following file structure in $GOPATH/src

bitbucket.org/MyName/ProjectName

I have follwoing files here

ProjectName
 - controllers/
    - meController.go
 - app.go

In app.go I'm importing my controller like that:

import "bitbucket.org/MyName/ProjectName/controllers"

And in main func I'm trying to use it's method.

meController = new(controllers.meController)
m.Get("/", meController.Index)

My meController.go looks like this

package controllers

type meController struct {

}

func (controller *meController) Index () string {
  return "Hello World"
}

But I'm getting this error:

./app.go:5: imported and not used: "bitbucket.org/MyName/ProjectName/controllers"
./app.go:12: undefined: meController

I don't have any idea how to get this to work.

Any ideas?

Thanks!

In Go, every symbol that starts with lowercase is not exported by the package. call your struct MeController and you'll be fine.

It's one of the most important idioms in Go, and same goes for struct members - it's a simplistic way of saying public/private. Some people like it, some people hate it. Personally I like it. – Not_a_Golfer May 16 '14 at 19:43
