I am looking for a functionality in vimdiff where on opening the diff, it could use the info. from cscope etc. such that the lines changed if are in within a function, that function will be unfolded and rest of the unchanged code should remain folded. Using context value in diffopt, we can specify the no. of neighboring lines which stays unfolded.

  • By default creating a diff view sets the fold expression to "diff", but in theory you might be able to change this. How would Vim know which function to unfold? – Ben Feb 04 '14 at 12:53
  • Oh, and any answer would probably require a LOT of scripting. There is no built-in way. – Ben Feb 04 '14 at 12:53
  • Ben, vim can know in similar way it jumps to start or end of the function by pressing [[ or ]] – Kapil Jain Feb 23 '14 at 07:27
  • So, you want to unfold EVERY function with changed code? And always the entire function, instead of using a set number of lines? By the way, ]] and [[ don't use cscope or anything, they're just "dumb" text searches. – Ben Feb 24 '14 at 15:25
  • yes, I want to unfold every function with changed code instead of fixed no. of lines. – Kapil Jain Feb 25 '14 at 16:59
