If that is the case, perhaps you can script it such that you skip over "changed" highlight areas, by repeatedly traversing diffs via "]c" or "[c". This can be achieved by using vim functions diff_hlID() and synIDattr(). I had posted a script sometime ago that searches for the exact changed text within a changed line using the above logic. You can modify that to suit to your needs. Regards, -Arun -- -- You received this message from the "vim_use" maillist. Do not top-post! Type your reply below the text you are replying to.

I've occasionally hacked this by inserting a unique tag (usually just
an incrementing number) after each line in the file, something like
:windo g/^/put='Unique line: '.((line('.')/2)+1)
which gives fixed boundaries for the diff algorithm to sync up with
after every line.
It's a hack, and it's far from perfect, but it's helped in the couple
occasions I've wanted it.

Hi Gary, That's insightful but is the side-by-side comparison I was hoping for in vim so I could visually assess how the collections differed.

I _think_ I understand what you want, but I don't know of a way to make Vim's internal comparison algorithm do that. Either of these two Linux commands will generate an output of only the lines common to file1 and file2, if that helps. diff --changed-group-format= file1 file2 comm -12 file1 file2 The comm command requires that the two files be sorted, but that's what you have.

I have the most recent version of vim with a diff utility, however I do not see anything diff.txt or diffopt that allows me to specify matches must be complete lines and not partial. I am trying to compare collections of strings, where I am not interested in similar items, only exact. The collections are sorted so I want to see filler where an exact line match is not found.
