This is Wordle implemented as a Multiboot application. You load the executable file using GNU GRUB and you get a fullscreen Wordle that run without an operating system.
So it is like... its own operating system I guess?
Gringo alert: it is using a Spanish dictionary. You have been warned. The list of words comes from wspanish.
I copied and pasted files from my other operating system repository, NativeOS, so that I could re-use the functions for drawing to the screen or reading from the keyboard. I just removed the main function and replaced it with a call to wordle() to start the game but there are a lot of things that are part of the other kernel, such as a VFS (yes) and a lot of standard library functions that are not used.
That is why at the moment it looks like this. I only modified the files that I need to touch, so everything else looks the same. I did not even rename the executable files or the comments LUL.
The thing you are looking for is in the wordleOS/wordle.c file. I did this in a livestream in a couple hours so it is not the best quality and not the best commented code though. Please be considerate at me. I might cleanup this in the future. Or not.
To download a ISO, check the releases for an ISO that you can boot in a virtual machine like QEMU, or in an old computer. I suspect this is not going to work in EFI systems because I don't know EFI yet.
To build this, you are going to need clang. Might or might not work with GCC. Run:
make wordle.elfto build the kernel as a multiboot filemake wordle.isoto build the ISO file if you have grub-mkrescue installedmake qemuto run the kernel in QEMU if you have qemu-system-i386 installed
