Nonnas against slop.
nonna is a code slop detector. It finds copy-pasted, reheated Python functions hiding under different variable names, the kind of thing a nonna would spot immediately because she is just like that: amazing.
Good code is like nonna's cooking: made with intention, distinct, recognisable 🍝. Slop is slop. She can tell.
100% match between KexGSSGex._generate_x and KexGex._generate_x in paramiko. Identical crypto key generation logic, two different class names.
nonna finds structurally similar functions across your codebase even when variable names, comments, and formatting differ. It extracts a data-flow graph from each function, computes IDF-weighted structural feature hashes, and scores pairs by similarity. Rename-invariant, noise-resistant. Powered by Rust and tree-sitter.
