Question

Suppose I have a package within a package github.com/user/foo:

foo/
  main.go (package main)
  bar/
    bar.go (package bar)

Now, within bar.go I would like to use an exported type from main.go.

package main
type FooBar struct {}

If I try to import "github.com/user/foo" I get cycled imports not allowed error. Is there any way to do this, other than to create own repo for bar, which I don't want.

Answer 1

You can separate it like:

foo/
  main.go (package main)
  foo/
    foo.go (package foo)
  bar/
    bar.go (package bar)

then import "path/foo/foo" in bar.go
