ccterm: casept's crappy terminal emulator

This is an extremely barebones (as in "doesn't even handle backspace properly or scroll") terminal emulator I wrote for fun in about a day, mostly as an exercise in C++, SDL2 and a bit of Unix internals demystification.

Building

I've only ever tested the code on NixOS with the build configuration described in shell.nix, but it should (at least in theory) be portable to at least other Linux flavors, MacOS, and the BSD's.

The easy way to build is using a nix-shell:

$ nix-shell
[nix-shell:~/dev/ccterm]$ mkdir build && cd build
[nix-shell:~/dev/ccterm/build]$ cmake -G Ninja ../
[nix-shell:~/dev/ccterm/build]$ ninja
[nix-shell:~/dev/ccterm/build]$ ./ccterm

Alternatively, scrounge together the following dependencies by hand:

• Any reasonably C++20-compliant compiler
• cmake >= 3.19
• fmt >= 7.1.3
• SDL2 >= 2.0.14
• SDL2_ttf >= 2.0.15

Earlier dependency versions may work, but are entirely untested.
