Trim & definitions?

[mgoodness]

I have a number of definitions in base.cue:

package stats_api

import (
	"k8s.io/api/core/v1"
)

#CommonLabels: {
	app:     string
	release: string
	...
}

#BaseApp: {
	_CommonLabels: #CommonLabels
	_Name:         string | *"\(_CommonLabels.release)-\(_CommonLabels.app)"

	serviceAccount: v1.#ServiceAccount & {
		apiVersion: "v1"
		kind:       "ServiceAccount"
		metadata: {
			labels: {
				_CommonLabels
				...
			}
			name: _Name
		}
	}
}

#IngressGCE: {
	_CommonLabels: #CommonLabels
	_Name:         string | *"\(_CommonLabels.release)-\(_CommonLabels.app)"

	backendConfig: {
		apiVersion: "cloud.google.com/v1beta1"
		kind:       "BackendConfig"
		metadata: {
			labels: {
				_CommonLabels
				...
			}
			name: _Name
		}
	}
}

That I reference from stats-api.cue:

package stats_api

stats_api: [Release=_]: {
	#BaseApp
	#IngressGCE

	_CommonLabels: #CommonLabels & {
		app:     "stats-api"
		release: Release
	}

	backendConfig: spec: {
		connectionDraining: drainingTimeoutSec: 300
		timeoutSec: 300
	}
}

Finally, I've imported the following test.cue from YAML:

package stats_api

stats_api: test: serviceAccount: {
	apiVersion: "v1"
	kind:       "ServiceAccount"
	metadata: {
		labels: {
			app:     "stats-api"
			release: "test"
		}
		name: "test-stats-api"
	}
}
stats_api: test: backendConfig: {
	apiVersion: "cloud.google.com/v1beta1"
	kind:       "BackendConfig"
	metadata: {
		labels: {
			app:     "stats-api"
			release: "test"
		}
		name: "test-stats-api"
	}
	spec: {
		connectionDraining: drainingTimeoutSec: 300
		timeoutSec: 300
	}
}

After I run cue trim -s ./... I expect test.cue to contain something like:

package stats_api

mlb_app: "stats-api": test: {}
mlb_app: "stats-api": test: {}

or, better still:

package stats_api

mlb_app: "stats-api": test: {}

but am actually left with:

package stats_api

stats_api: test: serviceAccount: {
	apiVersion: "v1"
	kind:       "ServiceAccount"
	metadata: {
		labels: {
			app:     "stats-api"
			release: "test"
		}
		name: "test-stats-api"
	}
}
stats_api: test: backendConfig: {
	apiVersion: "cloud.google.com/v1beta1"
	kind:       "BackendConfig"
	metadata: {
		labels: {
			app:     "stats-api"
			release: "test"
		}
		name: "test-stats-api"
	}
}

So only stats_api: test: backendConfig: spec has been trimmed.

Feature, bug, or PEBCAK?

@mgoodness this basically falls under a feature request. Because every aspect of cue trim's detection of what can be trimmed has to be coded separately. I'll reference this in a new issue (feature request)

Thanks, Paul!
