So, the old behavior we just had the object access baked into the string, and now we actually use an array type?
Seems like a good refactor to me.

Yes, the generator keeps the parts as an array, and we only merge them with ?. in the template.

Fixes googleapis/google-cloud-node-core#572. The generated code for routing headers should use optional chaining (
?.) instead of just dots for nested field names. Currently, it breaks compilation for Cloud Run v2 client library.The change includes a small refactor: it's not correct to concatenate a dot-separated name in the generator code because, by design, the generator has no knowledge of the target language. All language specific stuff must be limited to the templates. So now the generator will only keep the list of camelCased field names, that will be joined (with
?.) in the template.
