'Vimdiff - How to hide all same lines in both files and show only different ones

vimdiff file1 file2

besides differences shows also same lines from both files. Is it possible to hide them? How to do it?



Solution 1:[1]

As Vim is a text editor (not a specialized diff viewer), the full contents of both files are kept (so you can do edits and persist them). Vim usually just "hides" multiple identical lines by folding them away; they are still present, just not visible.

You can influence how many identical lines are kept around changes (default: 6 lines above and below) via the context value of the 'diffopt' option. So, to completely fold all identical lines:

:set diffopt+=context:0

It is still showing common lines if common line is going in sequence with different. one after another

The solution suggested by Ingo Karkat worked perfectly in Linux. Thanks for sharing it. However, it's not working on Mac.
