You can see [how I made it here](https://github.com/tozd/docker-nginx-proxy/blob/master/dockergen/hosts.tmpl).

Also see: https://github.com/jwilder/docker-gen/issues/149

I think it would be useful to have a way to register custom allowed transformations (or even SQL code for conversion).

It would also be useful to rename them, something like `__` so that any query assuming they are still around would start failing (one can detect bugs this way) and...

Oh, I see there is already `formerNames` in code. But there is nothing documented about it. So maybe just documentation is missing?

I also have this need. I would need to switch some props on the parent component when child `portal-target` component is in use, to make the space. I have something...

So whole `$event` is `null` when the portal target is not active?

I see, it is `true` and `false`. While this is great, this is different from [documentation here](https://linusborg.github.io/portal-vue/#/docs/portal-target?id=events-api)? Or am I missing something?

Ohhhh. Thanks! So should this issue just be resolved by documenting this pattern?

No, I am at the end not using this package.
