c++ - 移动到 block 代码的中间

Question

我试图使用 Vim 将光标移动到代码块的中间，但我不知道该怎么做:

//cursor is for instance here.

{
    //or here

    //some code
    // .... **** move cursor here ****
    //some more code 

}

最终的想法是有一个保存当前位置的快捷方式，将光标移动到代码块的中间，将当前行设置到屏幕的中间(使用快捷方式“zz”)，然后移动回到保存的位置。

我更喜欢内置的 vim 功能，但插件也可以。

编辑:这是针对 C++ 的，所以我希望它用于方括号 {}。

Answer 1

我试了一下(又快又脏):

function! Middleize()

  " use ]M to jump to either the end of the current method if we are in it
  " or the start of the next method if we are above the method
  normal! ]M

  " we record the current line number
  let first_line = line('.')

  " we go to the other end of the method
  normal! %

  " we record the current line number
  let second_line = line('.')

  " we started either from the top or from the bottom of the method
  " so we have to take that into account when calculating the number
  " of the line we want to jump to
  if first_line < second_line
    let middle_line = first_line + ((second_line - first_line) / 2)
  else
    let middle_line = ((first_line - second_line) / 2) + second_line
  endif

  " let's go!
  execute "normal! " . middle_line . "Gzz"
endfunction

nnoremap <F5> :call Middleize()<CR>
