What is the Patch / Diff Viewer?
Code review often means reading .patch or .diff files whose raw format buries the changes. This viewer parses unified diff format, lists every file touched with +/− counts, and explains each hunk header (@@ -1,4 +1,6 @@) — turning wall-of-text patches into a scannable summary.
Frequently Asked Questions (FAQ)
