当使用omap或onoremap声明映射时,我希望能够处理运动将是blockwise,linewise或standard的情况.
例如,让我们考虑以下块：
abcd efgh ijkl mnop
光标位于字母f上.假设我将K的运算符映射定义为：normal！ vjl(转到字母k).
onoremap K :normal! vjl<cr>
有趣的是,当我运行dvK,dK,d ^ VK时我分别得到了
abcd abcd abcd
el el eh
mnop mnop il
mnop
但是当我运行dVK它不起作用时,我和dvK完全一样.
我尝试使用visualmode()(映射定义为@ = visualmode()< cr> jl< cr>但这不起作用.看来当你使用v,V时,这个函数的返回值不会立即受到影响CTRL-V处于操作符挂起模式.
有人有线索吗？
谢谢
我已经写了一些关于运算符挂起映射的答案.在
one of them1中,我根据文档概述了应该处理各种情况(char,line,block wise选择)的函数的大纲：
原文链接：https://www.f2er.com/bash/384887.htmlg@{motion} Call the function set by the 'operatorfunc' option.
The '[ mark is positioned at the start of the text
moved over by {motion},the '] mark on the last
character of the text.
The function is called with one String argument:
"line" {motion} was |linewise|
"char" {motion} was |characterwise|
"block" {motion} was |blockwise-visual|
Although "block" would rarely appear,since it can
only result from Visual mode where "g@" is not useful.
{not available when compiled without the |+eval|
feature}
以下是使用< F4>：>计算空格数的示例
nmap <silent> <F4> :set opfunc=CountSpaces<CR>g@
vmap <silent> <F4> :<C-U>call CountSpaces(visualmode(),1)<CR>
function! CountSpaces(type,...)
let sel_save = &selection
let &selection = "inclusive"
let reg_save = @@
if a:0 " Invoked from Visual mode,use '< and '> marks.
silent exe "normal! `<" . a:type . "`>y"
elseif a:type == 'line'
silent exe "normal! '[V']y"
elseif a:type == 'block'
silent exe "normal! `[\<C-V>`]y"
else
silent exe "normal! `[v`]y"
endif
echomsg strlen(substitute(@@,'[^ ]','','g'))
let &selection = sel_save
let @@ = reg_save
endfunction
