Description
Toggle competitive programming macros and typedefs inline. Codeforces Un-definer is a small reading helper for competitive programming source code pages. It adds intuitive toggle buttons next to C++ #define macros, typedef declarations, and simple using aliases. When you click a button, the declaration line is crossed out and matching usages in the displayed code are rewritten inline. Supported sites: - Codeforces - AtCoder - QOJ - OJUZ - CodeChef Features: - Toggle #define macros directly on submission pages. - Toggle simple typedef and using aliases. - Red/green buttons for #define macros. - Orange/blue buttons for type aliases. - 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, template tricks, and unusual formatting may not be expanded correctly.
