Question

我找到了this function：

" Set up a keymapping from <Leader>df to a function call.
" (Note the function doesn't need to be defined beforehand.)
" Run this mapping silently. That is, when I call this mapping,
" don't bother showing "call DiffToggle()" on the command line.
nnoremap <silent> <Leader>df :call DiffToggle()<CR>

" Define a function called DiffToggle.
" The ! overwrites any existing definition by this name.
function! DiffToggle()
    " Test the setting 'diff', to see if it's on or off.
    " (Any :set option can be tested with &name.
    " See :help expr-option.)
    if &diff
        diffoff
    else
        diffthis
    endif
:endfunction

现在我想添加一个额外的条件，如果有一些选定的文本（可视模式）调用另一个命令而不是diffthis，Linediff

阅读函数我想我需要一些额外的设置选项来测试，就像他们使用&dif但使用visual选项一样。类似的东西：

function! DiffToggle()
    if &dif
        diffoff
    elseif &visual
        Linediff
    else
        diffthis
    endif
:endfunction

这不起作用，但有没有人有任何线索让它起作用？此外，任何有关此类设置变量在vim中的用途和数量的参考都是非常有用的。

修改我在我的vimrc中结束了这个，（作品）：

"LINEDIFF/VIMDIFF
 "--------------

nnoremap <silent> <Leader>df :call DiffToggle('n')<CR>
xnoremap <silent> <Leader>df :call DiffToggle('x')<CR>

function! DiffToggle(mode) range
    echo "difftoggle..."
    if &diff
        diffoff
        echo "diffoff..."
    else
        if a:mode=='x'
            echo "linediff..."
            echo a:firstline."---".a:lastline
            call linediff#Linediff(a:firstline, a:lastline)
        else
            echo "diff..."
            diffthis
        endif
    endif
:endfunction

只需拨打xnoremap <Leader>df ...稍微不同的功能即可？当您处于可视模式时，将调用该文件。

或者，将模式作为参数传递给您的函数：

nnoremap <silent> <Leader>df :call DiffToggle('n')<CR>
xnoremap <silent> <Leader>df :call DiffToggle('x')<CR>

...并检查您的函数中的a:mode，具有以下原型：

function! DiffToggle(mode)

编程diff vim函数，vim diff mapping
