help , how to use vim-diff

[colinvivy]

hello ynkdir !

First of all ,thank you for this vim-diff plugin for vim , but I don't know how to use it ... poor man ..

I copy "autoload/vim.diff" to "~/.vim/autoload/" , and add some config ":set runtimepath+=/path/to/vim-diff :set iffexpr=diff#diffexpr()
" in my gvimrc . restart vim ,using vimdiff command , it doesn't work.

Cound you show me more detail about this ?

Best Regards!

Hi colinvivy.

vimdiff command doesn't load gvimrc.
Add those config to vimrc (not gvimrc).
Or use gvimdiff command.

vim-diff only works for 2-file diff.

vim-diff only works for 2-file diff.

I was mistaken. It seems that 'diffexpr' also works for 3-file diff...

Hi, ynkdir .
I am so sorry , I am late .

My editor is vim for Mac OS X, so I can only find gvimrc .
And I try to use gvimdiff , it still doesn't work , leave this error information: Not an editor command: gvimdiff

Anything wrong with im my MacVim ?

No problem.

vimdiff and gvimdiff are not vim's command. You can run these command
from shell. If these command are not installed in your system, you can
use '-d' option.

$ vim -d file1 file2
# or
$ gvim -d file1 file2

Another way to view diff, you can use :diffsplit ex-command. Try the following command in Vim.

:edit file1
:diffsplit file2

If you use vim, add the following command to your ~/.vimrc.
If you use gvim, add the following command to your ~/.vimrc or ~/.gvimrc
If the file is not exist, create new file.

:set runtimepath+=/path/to/vim-diff
:set diffexpr=diff#diffexpr()

Replace /path/to/vim-diff to actual directory where you downloaded
vim-diff. If you copied diff.vim to your ~/.vim/autoload/ directory,
you don't need to set ":set runtimepath+=...".

well , at last I use this way to diff file

:edit file1
:diffsplit file2

Thank you for your patience , So kind of you !
