在新缩进级别vim之后的换行后缩进

Question

在vim中，我只是将我的制表符从2改为4个空格。这工作得很好-当我按tab时，它缩进了4个空格。当我添加相同缩进的新行时，它可以工作。然而，当我需要一个新的缩进水平，并按下回车键，它只缩进2个空格。

previously fixed code{
    previously indented code;
    if (new amount of indenting should happen){
      only this much is given by vim;
        but hitting tab takes me here (where I want to be);
    }
}

你知道我需要改变什么设置才能让它工作吗?我试过了我能找到的每一个(自动缩进，缩进，设置各种tab类型变量)，但无济于事。

运行:help tabstop检查帮助文件时，将得到:

'tabstop' 'ts'      number  (default 8)
            local to buffer
    Number of spaces that a <Tab> in the file counts for.  Also see
    |:retab| command, and 'softtabstop' option.
    Note: Setting 'tabstop' to any other value than 8 can make your file
    appear wrong in many places (e.g., when printing it).
    There are four main ways to use tabs in Vim:
    1. Always keep 'tabstop' at 8, set 'softtabstop' and 'shiftwidth' to 4
       (or 3 or whatever you prefer) and use 'noexpandtab'.  Then Vim
       will use a mix of tabs and spaces, but typing <Tab> and <BS> will
       behave like a tab appears every 4 (or 3) characters.
    2. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use
       'expandtab'.  This way you will always insert spaces.  The
       formatting will never be messed up when 'tabstop' is changed.
    3. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use a
       |modeline| to set these values when editing the file again.  Only
       works when using Vim to edit the file.
    4. Always set 'tabstop' and 'shiftwidth' to the same value, and
       'noexpandtab'.  This should then work (for initial indents only)
       for any tabstop setting that people use.  It might be nice to have
       tabs after the first non-blank inserted as spaces if you do this
       though.  Otherwise aligned comments will be wrong when 'tabstop' is
       changed.

所以把它放到你的。vimrc文件中，一切正常

set expandtab       "Use softtabstop spaces instead of tab characters for indentation
set shiftwidth=4    "Indent by 4 spaces when using >>, <<, == etc.
set softtabstop=4   "Indent by 4 spaces when pressing <TAB>
set autoindent      "Keep indentation from previous line
set smartindent     "Automatically inserts indentation in some cases
set cindent         "Like smartindent, but stricter and more customisable
