It adds intuitive toggle buttons next to C++ #define macros and simple typedef declarations. When you click a button, the declaration line is crossed out and matching usages in the displayed code are rewritten inline.

Features:
- Toggle #define macros directly on Codeforces submission pages.
- Toggle simple typedef aliases.
- Red/green buttons for #define.
- Orange/blue buttons for typedef.
- Highlights lines that were changed.
- Works locally in the browser.
- Does not collect, store, or transmit user data.

Codeforces Un-definer is designed to make macro-heavy competitive programming submissions easier to read. It is a reading helper, not a full C++ preprocessor, so very complex macros may not be expanded correctly.

Codeforces Un-definer is an independent tool and is not affiliated with, endorsed by, or sponsored by Codeforces.
