# DOOMFIRE
## Test your TTY's might!
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
Each MR tested on OX Sequia 15.2 / M1 w/zig 0.13 on OSX Kitty, VS Code, Alacritty, Terminal.
EDIT: Now tested on Artix Linux - links against libc to get the size of the TTY.
EDIT: 2025 - Windows does not currently function properly, though it will compile, it may panic.
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 (OSX) - great
* Terminal.app (OSX) - poor -- seems to drop framerates
* VS Code (Linux, OSX) - great
* Warp - great
* Alacritty (artix linux, OSX) - great
* VS Code (Windows) - poor FPS
* CMD, Powershell (Windows) - compiles but fails to render DOOMFire.
Note: Currently uses `u64` and thus is limited to x64 architecture, for now. In the future, will convert to a comptime approach for greater flexibility.
