DOOMFIRE

Test your TTY's might!

The doom-fire algo can push upwards of 180k a frame - results may vary! It is, to my surprise, a nice TTY stress test.

As a comparison, this is the younger sibling of a node variant ( https://github.com/const-void/DOOM-fire-node ).

INSTALL

Tested on OX Monterey / M1 w/zig 0.9...

EDIT: Now tested on Artix Linux - links against libc to get the size of the TTY.

EDIT: 2024 - Now tested with Windows - Win32 Compatible, thank you @marler8997!

This means that the program does rely on libc, this shouldn't be a problem.

$ git clone https://github.com/const-void/DOOM-fire-zig/
$ cd DOOM-fire-zig
$ zig build run
...

Results

iTerm.app - ok
kitty.app - great
Terminal.app - poor -- seems to drop framerates
VS Code - great
Alacritty (artix linux) - great
Powershell/CMD
