VIM全局多行搜索和替换维护缩进

Question

I am trying to perform a multiple line search and replace while retaining the indent, leading space, in the code I am working with. Below is a text sample which approximates the situation. The problem I'm having is preserving the white space. I'm hoping for a non-plugin, plain jane VIM solution via :%s/ ......

VIM 7.2 on Windows 7 autoindent is on expandtab is on

Starting with:

  apples,
  banannas,
  cherries,
  plums

  peas,
  green beans,
  corn,
  squash

        apples,
        banannas,
        cherries,
        plums

I would like to add "pears,", without the double quotes and following the "cherries," line in the list. The desired outcome is:

  apples,
  banannas,
  cherries,
  pears,
  plums

  peas,
  green beans,
  corn,
  squash

        apples,
        banannas,
        cherries,
        pears,
        plums

Trying :%s/cherries,/&\\rpears,/g yields ...

      apples,
      banannas,
      cherries,
pears,
      plums

      peas,
      green beans,
      corn,
      squash

            apples,
            banannas,
            cherries,
pears,
            plums

Trying :%s/cherries,_s.\\s*/&pears,\\r/g yields ...

      apples,
      banannas,
      cherries,
      pears,
plums

      peas,
      green beans,
      corn,
      squash

            apples,
            banannas,
            cherries,
            pears,
plums

Thank you!

Answer 1

您可以利用:g和带有普通o自动缩进功能：

:g/cherries,/normal opears,

Answer 2

Try to extract the whitespace just before the word and insert it in the replacement part ( \\1 ).

NOTE that I use \\v at the beginning but it does not match anything, it is to make the regular expression very magic and avoid to escape many characters, like parentheses.

:%s/\v(\s*)cherries,/&\r\1pears,/g

It yields:

  apples,
  banannas,
  cherries,
  pears,
  plums

  peas, 
  green beans,
  corn,
  squash

        apples,
        banannas,
        cherries,
        pears,
        plums
