Three weeks ago, I submitted a Pull Request for totp-cli. (see https://github.com/macports/macports-ports/pull/17418). But the PR has not been assigned to anyone for a review and merge. It is a simple update to an existing port. It should be fairly straightforward.
When someone gets a chance, please take a look at it. I will be traveling soon, I would like to address any issues now, if at all possible. Many thanks, Rob
