Tags across packages

[maurerbot]

cue seems to be unable to pick up tags across packages.

What version of CUE are you using (cue version)?

cue version v0.4.0 linux/amd64

Does this issue reproduce with the latest release?

Yes

What did you do?

cue/cue.mod/module.cue
module: my.tld

cue/schema/base/base.cue

package base

#metadata: {
	name:         string @tag(name)
	description?: string
}

let Spec = {}

#base: {
	apiVersion: string
	kind:       string
	metadata:   #metadata
	spec?:      Spec
}

cue/schema/v1alpha1/test.cue

package v1alpha1

import "my.tld/schema/base"

let Spec = {
	keys?: [...{
		name: string
		pk:   =~"([a-zA-Z0-9_-]){8,256}"
	}]
} 

test: base.#base & {
	kind:       "test"
	apiVersion: "my.tld/v1alpha1"
	spec: Spec
}

cue eval ./schema/v1alpha1/... -t name="foo" -p v1alpha1 -e test --out=yaml

What did you expect to see?

apiVersion: "my.tld/v1alpha1"
kind:       test
metadata: 
    name: foo

spec: {...}

What did you see instead?

no tag for "name"

Alternatively

cue eval ./schema/... -t name="foo"
#metadata: {
    name: "foo"
}
#base: {
    apiVersion: string
    kind:       string
    metadata: {
        name: "foo"
    }
}
// ---
test: {
    apiVersion: "my.tld/v1alpha1"
    kind:       "test"
    metadata: {
        name: string // this isn't picked up
    }
    spec: {}
}

Other Questions

• Not sure if leveraging the lattice values as a means to define Spec is the right approach

[maurerbot]

Adding test:metadata:name: string @tag(name) to test.cue seems to work but feels off to me.
