For these situations you can manually instruct KDiff3 to align certain lines. Mark the text for which you want to improve the alignment with the mouse as you would for copy and paste in the first diff view and then choose" Add Manual Diff Alignment" in the" Diffview" menu (keyboard shortcut" CtrlY" ).
kdiff3 has a feature to manually align lines that don't initially match up, when the builtin line matching gets it wrong. This can be very useful sometimes, but occasionally I make a mistake and a Hi Joachim and others, tl; dr: I'm asking for some ideas on how to get a good test set for the diffalignment algorithm of kdiff3. A while ago I wrote the alignmenttest in the test directory. This test checks how kdiff3 arranges the lines of 3 files in a threeway diffmerge, so which parts of the file it decides to put next to each other.
After selecting the B and C lines, the" diff" routine would have to be refreshed, esentially" starting over" at each manual alignment until the end of the file. Sometimes the current auto grouping aligns things that I do not want aligned due to partial similarities in text. Whoever wrote KDiff3 was a genious because he recognised that diff tools can sometimes get the alignment wrong. He is best written as they, since this could have very well been authored by a she. Also, genius is misspelled.
The" Add Manual Diff Alignment" in KDiff3 doesn't seem to do anything. The online documentation is rather sparse. Does this function actually work? When comparing Kdiff3 vs GNU Diffutils (diff), the Slant community recommends Kdiff3 for most people. Supports manual code aligning. With selecting code in one window and hitting CtrlY, then selecting some other code in second window and also hitting CtrlY you can manually align the code.
