I feel like there’s actually a growing subculture of C programmers of late, seemingly spawned by Casey Muratori’s Handmade Hero series, Zed Shaw’s “Learn C The Hard” way and other more recent popularizations of C and low level programming ideas. There’s a whole “Handmade” software scene growing up, seemingly as a reaction against the bloat and over engineering of more recent software trends like Electron and web apps.
Just the other day I stumbled across a vibrant Discord group focused on a fairly new but surprisingly feature complete game engine called Gunslinger, written entirely in C99.
I’ve been working on my own C-based game engine for awhile too after having been exposed to the ideas of Handmade Hero, as well as from the influence of a good friend who has been writing games in C for many years. He’s now working on an application called Pixel CNC for generating 3D tool paths from 2D images.
