Fix resolving @scope/name namespaces

[buschtoens]

It is possible resolve modules from other packages using namespaces. For instance, the following looks up the intl service directly from the ember-intl package:

this.owner.lookup('ember-intl@service:intl');
this.owner.lookup('service:ember-intl@intl');

Notably, this instance is !== to the app re-export that is merged with the host app:

this.owner.lookup('service:intl');

This is expected behavior.

So generalizing, the pattern for looking up something from a foreign package is:

this.owner.lookup(`${packageName}@{type}:${name}`);
this.owner.lookup(`{type}:${packageName}@${name}`);

Unfortunately, this does not work for packages that have a scoped name, e.g. @corp/fancy-addon.

The invocation would look like:

this.owner.lookup('@corp/fancy-addon@service:intl');
this.owner.lookup('service:@corp/fancy-addon@intl');

parseName(fullNane) does not support this, as it was written before package scopes were introduced and only expected a single @ to be present.

	function parseName(fullName) {
	if (fullName.parsedName === true) { return fullName; }
	let prefix, type, name;
	let fullNameParts = fullName.split('@');
	if (fullNameParts.length === 2) {
	let prefixParts = fullNameParts[0].split(':');
	if (prefixParts.length === 2) {
	if (prefixParts[1].length === 0) {
	type = prefixParts[0];
	name = `@${fullNameParts[1]}`;
	} else {
	prefix = prefixParts[1];
	type = prefixParts[0];
	name = fullNameParts[1];
	}
	} else {
	let nameParts = fullNameParts[1].split(':');
	prefix = fullNameParts[0];
	type = nameParts[0];
	name = nameParts[1];
	}
	if (type === 'template' && prefix.lastIndexOf('components/', 0) === 0) {
	name = `components/${name}`;
	prefix = prefix.slice(11);
	}
	} else {
	fullNameParts = fullName.split(':');
	type = fullNameParts[0];
	name = fullNameParts[1];
	}
	let fullNameWithoutType = name;
	let namespace = get(this, 'namespace');
	let root = namespace;
	return {
	parsedName: true,
	fullName: fullName,
	prefix: prefix || this.prefix({type: type}),
	type: type,
	fullNameWithoutType: fullNameWithoutType,
	name: name,
	root: root,
	resolveMethodName: "resolve" + classify(type)
	};
	}

This PR, so far, adds failing tests for scoped package names.

Is this something that we would want to fix? I personally have an interest in it and would finish the PR, if so.

I seem to have fixed it. 🤔

All existing tests are still passing and the newly added tests pass as well.

CI is failing for an unrelated reason:

error semver@7.1.3: The engine "node" is incompatible with this module. Expected version ">=10". Got "8.17.0"

error Found incompatible module.

The command "yarn install --no-lockfile --non-interactive" failed and exited with 1 during .

Fixing in #532.

[buschtoens]

Assuming CI is fixed (#532), would this PR be mergeable? Is there something I need to improve or do we not want to support this in the first place?

[buschtoens]

The PR is rebased and CI is passing. ✅
