If you think this project sounds interesting, you should check out Lagrange as well. It's a very similar client, built in C with SDL, and has support for Gopher!
¹ Namely, operating systems with an SDL 2.0 port. Check out the list here.
stb_truetype.h is used for text rendering. As it mentions in a comment at the start, it doesn't check offsets found in the font files it reads, which could lead to this program reading arbitrary memory. TODO: Provide a way to set the default font.
As a general consideration, you should probably avoid handling sensitive data with this application: while it is written with care, it is also the first relatively complicated C program I've ever written, so there probably are vulnerabilities all over the place.
All the build files are hand-written and very short, so feel free to study them if you come across issues.
The executable will be built into the

Nemini can be built with tcc! With slight

variable, as you'd assume:

The newest windows binaries released for LibreSSL (2.2.5, as I'm writing this) are too old to support the TOFU verification this program has, so you'll need to build LibreSSL yourself. Thankfully, it's pretty easy.

The configure.bat script should tell you if you're missing any of the prerequisites. If you want to build a 64-bit client, you need to edit every mention of x86 to x64 in configure.bat, and then build in a 64-bit Developer Command Prompt.

This program is (hopefully) written to be portable, and it uses SDL2 in a very straightforward way. Software rendering is supported. For OS-specific instructions, see the SDL wiki's installation instructions.
