meemo is a 1kLOC memory scanner.
It has no third party dependencies (not even curses).
When I was a kid I loved playing "3D Pinball for Windows – Space Cadet" on Windows XP.
To have the highscore in the house, I started using cheat engine.
meemo is a micro (bad) version of it.
It requires sudo since it uses the process_vm_readv and process_vm_writev syscalls.
More info about them here.
sudo meemo <pid>
I was inspired by Salvatore Sanfilippo's Kilo, a <1kLOC text editor.
