How could I use inner type?

[gobwas]

Hello! I have some code that looks like this:

package tpl

// template type Container(T)
type T int

type Container struct {
  field T
}

In some other place:

package tpl

//go:generate gotemplate "tpl" MyTypeContainer(otherpackage.MyType)

How could I tell to gotemplate to import otherpackage somehow? Is it possible?

Thanks anyway! )

A good question! I can think of two workarounds

First - alias the external type in your package, eg

type MyType otherpackage.MyType

The other would be to run goimports on the generated code. This will fix up missing imports. You could automate this in the go generate statements.

I think for a long term fix I should do this within the code.

Thanks!

Your proposed workaround does not work, as the local MyType is a different type from otherpackage.MyType.

With go 1.9, one can declare a type alias which would work, at the price of cluttering the package namespace.

I therefore propose an additional option to gotemplate that allows the user to specify import paths to add to the generated code.

This is fixed with PR #29. Something similar to goimports is run automatically on finishing the instantiation.
