Frequently asked questions
What algorithm powers the Utilix Diff Checker?
It uses Eugene Myers’s O(ND) difference algorithm via jsdiff, the same foundational algorithm used by Git.
Can I ignore indentation or trailing space changes?
Yes, enable the "Ignore Whitespace" toggle in the settings panel to focus strictly on semantic code changes.
How do I apply the exported .patch file in Git?
Download the .patch file and run `git apply document.patch` or `patch -p1 < document.patch` in your terminal.
Is my source code sent to a server?
Never. All comparisons happen inside your browser memory.
Does it show exact counts of added and removed lines?
Yes, the summary bar displays exact +Added and -Removed line counts in tabular numerals.
