As Tony suggested, check the value you have for 'diffexpr'.
I just did a fresh install of Vim 7.4 and did:
gvim -N -u NONE -i NONE
:source $VIMRUNTIME/vimrc_example.vim
This actually leaves 'diffexpr' empty.
I was then able to view a diff without seeing any error messages.
Vim is also using the correct 'diff.exe' distributed with Vim:
:!start cmd
C:\Users\btfritz>where diff
C:\Program Files (x86)\vim\vim74\diff.exe
I guess probably your diffexpr is not correct.
:set diffexpr?
diffexpr=MyDiff()
then I put the line:
echo '!' . cmd . ' ' . opt . arg1 . ' ' . arg2 . ' > ' . arg3 . eq
before this in the _vimrc (copied from vimrc_example.vim):
silent execute '!' . cmd . ' ' . opt . arg1 . ' ' . arg2 . ' > ' .
arg3 . eq
:vert diffsp vimrc~
!""C:\Program Files (x86)\Vim\vim74\diff" -a --binnary
C:\Users\Marcio\AppData\Local\Temp\VIo4C8B.tmp
C:\Users\Marcio\AppData\Local\Temp\VIn4C8C.tmp >
C:\Users\Marcio\AppData\Local\Temp\VId4C8D.tmp"
E810: Cannot read or write temp files
E97: Cannot create diffs
I just remove the MyDiff() function from _vimrc then the diff works!
It is Ok for me, but is there a failure in the Vim instalation?
No. Your _vimrc is not part of the Vim installation. If you made an
unwarranted change in your vimrc, and removing that change cures your
problem, well, what can I say? Starting Vim as
vim -u NONE -N
or even as
C:
cd "\Program Files (x86)\vim\vim74"
vim -u .\vimrc_example.vim
ought to work. Making sure that your vimrc is sane is up to you.
Where was that 'diffexpr' set?
:verbose set diffexpr?
There is no MyDiff() in the vimrc_example.vim for Vim 7.4, but there is
one under ":help diff-diffexpr". Are you sure you copied it exactly?
What you typed above doesn't look the same to me as what I see in the
help. Where is the "cmd" variable set? How come you got --binnary with
two n's? This is what _I_ see in the help:
Example (this does almost the same as 'diffexpr' being empty): >
set diffexpr=MyDiff()
function MyDiff()
let opt = ""
if &diffopt =~ "icase"
let opt = opt . "-i "
endif
if &diffopt =~ "iwhite"
let opt = opt . "-b "
endif
silent execute "!diff -a --binary " . opt . v:fname_in . " " .
v:fname_new .
\ " > " . v:fname_out
endfunction
The "-a" argument is used to force comparing the files as text, comparing as
binaries isn't useful. The "--binary" argument makes the files read in binary
mode, so that a CTRL-Z doesn't end the text on DOS.
Notice v:fname_in, v:fname_out and v:fname_new which aren't the same as
arg1 arg2 arg3.
Best regards,
Tony.
