E97: Cannot create diffs

[abourree]

Hi

I clone your repository and try to compare the two following lines:
Toto
Tutu

I get the following error;
Error detected while processing function 20_Linediff..20_PerformDiff..linediff#differ#CreateDiffBuffer:
line 26:
E97: Cannot create diffs
Press ENTER or type command to continue

And then diff doesn't show diff

I notice that vimdiff raise same error now

Regards,

Arnaud

This doesn't seem like a problem with linediff, especially considering that, as you say, the same error happens with the standard vimdiff command.

Execute the command :help E97 to see some information about the error (or check it out online here). It seems like the diff command can't be called or there are problems with the shell interface.

There are some tips on how to debug the problems in that help section. Try them out and let me know.

Hi,

You are right, issue is not from Linediff. I remove MyDiff from .vimrc file and now it works perfectly. Thanks for your help and your script.

Arnaud.

I encountered the same problem, and the problem is indeed created by the MyDiff function. Here goes what I have removed. These lines were added for vim-latex-suite.

set diffexpr=MyDiff()
function! MyDiff()
    let opt = '-a --binary '
    if &diffopt =~ 'icase' | let opt = opt . '-i ' | endif
    if &diffopt =~ 'iwhite' | let opt = opt . '-b ' | endif
    let arg1 = v:fname_in
    if arg1 =~ ' ' | let arg1 = '"' . arg1 . '"' | endif
    let arg2 = v:fname_new
    if arg2 =~ ' ' | let arg2 = '"' . arg2 . '"' | endif
    let arg3 = v:fname_out
    if arg3 =~ ' ' | let arg3 = '"' . arg3 . '"' | endif
    let eq = ''
    if $VIMRUNTIME =~ ' '
        if &sh =~ '\<cmd'
            let cmd = '""' . $VIMRUNTIME . '\diff"'
            let eq = '"'
        else
            let cmd = substitute($VIMRUNTIME, ' ', '" ', '') . '\diff"'
        endif
    else
        let cmd = $VIMRUNTIME . '\diff'
    endif
    silent execute '!' . cmd . ' ' . opt . arg1 . ' ' . arg2 . ' > ' . arg3 . eq
endfunction
