I get a weird sense of catharsis from stuff written in C - thanks for this.
I'm struck by the fact that URL parsing accounts for about half the code -a stark reminder both of the effort required to handle formalspecifications properly, and of the value of the GPL.
Good stuff!

Hiya! I felt that the Gemini space has a lot of cool browers, but was
missing the basic works-everywhere client with few-to-no dependencies.
gmni fills that role:

Here's a recording which shows off some of its features:
https://asciinema.org/a/Y7viodM01e0AXYyf40CwSLAVA
Two tools are provided: gmni, a curl-like utility which executes Gemini
requests and writes the response to stdout, and gmnlm, a line-mode
interactive browser. The latter is demonstrated in the recording above.
The whole thing clocks in at approximately 3,000 lines of C11. It'll
grow a little bit with TOFU and client-side certificate support, but
otherwise it's pretty close to done. The only dependencies are a
POSIX-like system and OpenSSL.
The Gemini protocol implementation is pretty concise and
straightforward:
https://git.sr.ht/~sircmpwn/gmni/tree/master/include/gmni.h
https://git.sr.ht/~sircmpwn/gmni/tree/master/src/client.c
https://git.sr.ht/~sircmpwn/gmni/tree/master/src/parser.c
If there's any demand for it, I'll package these up into a library you
can link to. I also plan on writing a Gemini server in C with a similar
design approach.
Enjoy!
