vim – 是否可以在运算符挂起的映射中确定运动是线性,块状还是正

导读: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: abcdefghijklmnop 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! vjlcr 有趣的是,当我
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?
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:
g@{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 1 vim call a function from inside a vmap (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
