# DOOMFIRE

## Test your TTY's might!

![demo](https://user-images.githubusercontent.com/76228776/149635702-a331f892-7799-4f7f-a4a6-7048d3529dcf.mp4)

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 Sonoma 14.5 / M1 w/zig 0.13...

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](https://www.github.com/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

* Warp - great

* Alacritty (artix linux) - great

* Powershell/CMD
