Cedit is a single-file C text editor that runs anywhere you can compile C code – from resource-constrained embedded systems to PoS terminals. Unlike Vim or Emacs, it uses familiar GUI-like keybindings while maintaining terminal efficiency. The entire editor is a standalone binary that doesn't even require curses, making it perfect for systems where every kilobyte counts. Built on VT100 standards, it brings modern editing convenience to places traditional editors can't reach. Looking for feedback: I've been using this for firmware development on embedded devices where traditional editors are too heavy. Would love to hear thoughts from others working in resource-constrained environments.
