Tips
- Lines starting with + were added, lines starting with − were removed, and lines with two spaces are unchanged.
- Word mode is better for prose where sentences were reworded; line mode is better for code and lists.
- Ignoring case and whitespace is useful when comparing text that has passed through different editors.
- The algorithm finds the longest common subsequence, which is the same approach Git uses, so the output should look familiar.
Frequently asked questions
Why does one changed word show as a whole changed line?
Line mode treats a line as an atom — any change makes it a removal plus an addition. Switch to word mode to see the change at word granularity.
