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 ).
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: 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
...
- 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
- Powershell/CMD
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.
