Now that Rogallo is starting to settle down somewhat, with all the main Gemini Protocol work falling into place, I've been thinking about adding one or two adjacent protocols. The two most common and obvious ones are Finger and Gopher. While I'm still undecided about adding the latter, the former seems like a fun one to include (if only because I've had an account on plan.cat for around four years now).

With that in mind, much like I did with Wasat, I wrote a spec for what I wanted and pointed Antigravity at it. The result is Port79. As well as providing a library, there's also a small finger clone CLI, which can be run with python -m port79 (if it's installed as a library) or with port79 (if installed along with any command scripts).

Plan:
Rogallo v0.12.0, with some more QoL changes:

To be clear: this isn't intended to be a serious finger command (like, why would anyone even need that?), it's just a tool within the library that can be used to do some testing within a development (v)environment.

At some point soon I'll be adding port79 as a dependency of Rogallo and adding finger as a "native protocol".
