Ah, glad your issue was resolved. I did want to point out one thing: > 2.

Getting the topic via `create.CreateTopic` or `client.Topic` should work for subscriber creation. Both return `pubsub.Topic` struct[1], which can be used to call `topic.Publish` and pass to subscription config. I quickly tested this to confirm, code here[2]. Lastly, with regards to the cmdline examples, I'm guessing this was removed because we had the official gcloud sdk `gcloud pubsub ...`. Although the gcloud sdk doesn't use the Go client, I think we didn't think it would be necessary to support two API surfaces. We do keep our code samples in our golang-samples[3] repo, and I'm not sure if it was these samples that you found were hard to navigate, but if so, we're very much open to feedback. I think I can sort of see your point of how the cmdline example is easier to read (with it being all in one file), but it's part of the repo's style to keep code samples in separate files. For learning, I'll work on adding a more comprehensive end-to-end guide that lives in the package docs instead.
