I actually already use Gundo. I'm not trying to visually step through the changes. I literally want to end up with a Vim9 function that, when called with a time (such as for :earlier) or 'since last save', returns me a list of changed lines. I then will use that list to execute commands on those lines, such as removing trailing whitespace or reformatting them. For various reasons, I am not in a position to do those operations on the entire file, only on the bits I personally changed or added. I noticed that Eclipse has an option to only affect the lines that were explicitly modified, so was wondering if it was possible to do something like that in Vim. One obvious way would be to have Vim go to the :earlier state, grab the contents of the buffer, come back to 'now' and then manually do a diff to see what's changed. However, that seems expensive for a large file. I was wondering, instead, if there might be a way to somehow get access to the undo information kept by Vim. I tried :wundo, but the file that was written was in a binary format, so wasn't something I could parse. All the best, Salman -- -- You received this message from the "vim_use" maillist.
