Mark difference as ok in vimdiff
I have a couple of large json files that I need to check for errors and was wondering if it is possible to mark a difference as ok and have that apply for the whole diff session thereby elim开发者_如何学JAVAinating it further down in the file.
example
Name: Donald Duck | Name: Daisy Duck
Here I would like to be able to mark this change as an "ok" diff (i.e. I expect the name and apparent sex change).
Well, the way to do it in vim, would simply to do a custom diff expression
e.g. this should go in your .vimrc
set diffexpr=MyDiff()
function! MyDiff()
let opt = ""
if &diffopt =~ "icase"
let opt = opt . "-i "
endif
if &diffopt =~ "iwhite"
let opt = opt . "-Ewb "
endif
silent execute "!diff -I 'Duck' " . opt . v:fname_in . " " . v:fname_new .
\ " > " . v:fname_out
endfunction
Of course, you'd want to make it more flexible than that, but this should give you the general method
I don't think there is a built-in way to do that. But the way that occurs to me is to do substitute on the files, then rediff.
E.g., if that name change is OK, then just substitute in both files:
%s/Name: Donald Duck/Name: placeholder_1/g ; in file 1
%s/Name: Daisy Duck/Name: placeholder_1/g ; in file 2
You could do this with e.g. sed or perl before starting vim -d as well.
Now those will match. But a change from Donald Duck to Mickey Mouse won't, nor a change from Daffy Duck to Daisy Duck.
