Real Diff is a Chrome extension developed by ethdud1 that allows users to track the pure file changes of a specific file on GitHub Pull Request pages. This extension is especially useful for developers who want to exclude certain file changes and focus on the actual modifications made.

With Real Diff, users can easily view the net file changes without the interference of unwanted modifications. It provides a convenient way to analyze and understand the impact of pull requests on specific files.

For public repositories, Real Diff can be used without any additional token settings. However, to access private repositories, users need to provide a separate token through the Setting Page.

In the latestupdate, Real Diff introduces a new feature that allows users to exclude specific file names using regular expressions. Users can add or remove file names in the Config > Ignore section, providing even more flexibility in analyzing pull request changes.

Real Diff is a valuable tool for developers who want to accurately assess the impact of pull requests on specific files, making it easier to review and merge changes seamlessly.
