blocks|key|189334|text|更改缩进的一般方法是通过更改tabstop：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|189335|将文件粘贴到空缓冲区中，然后：|189336|:set+ts=2+sts=2+noet
:retab!|code-block|syntax|javascript|189337|这会将每2个空格更改为一个制表符，然后：|189338|:set+ts=4+sts=4+et
:retab|189339|这会将每个制表符更改为4个空格。|189340|这种方法的优点是，您还可以反过来使用它，例如，将4个空格转换为2个空格。|189341|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|V|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|W|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|X|8|@]|9|@]|A|$]]|$1|O|3|P|5|6|7|Y|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

A general way of changing the indent is by changing the tabstop:

Paste your file into an empty buffer, then:

<pre><code>:set ts=2 sts=2 noet
:retab!
</code></pre>

This changes every 2 spaces to a TAB character, then:

<pre><code>:set ts=4 sts=4 et
:retab
</code></pre>

This changes every TAB to 4 spaces.

The advantage of this method is that you can also use it the other way around, to convert from 4 to 2 spaces for example.

blocks|key|2804963|text|使用:set+shiftwidth=4和gg=G或许可以做到这一点。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2804964|entityMap^0|2|H|K|4|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

blocks|key|186651|text|我所做的与esneider和cforbish的方法非常相似，但输入速度更快一些：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|186652|:%25s/%5E\s*/&&|code-block|syntax|javascript|186653|只需将前导空格(空格或制表符)替换为两倍的前导空格(匹配的表达式替换为&)。|offset|length|style|CODE|186654|entityMap^0|0|0|Z|1|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

What I do is very similar to esneider and cforbish's approaches, but a bit quicker to type:

<pre><code>:%s/^\s*/&amp;&amp;

Simply replaces leading space (spaces or tabs) with twice as much leading space (<code>&amp;</code> is substituted with the matched expression).

This is a very old question, however all the answers are ... wrong ... Vim has a very easy way to reindent the entire file. I learned this after writing my own function to do it, so I'm in the same ignorance boat ;)

type 

<pre><code>gg=G
</code></pre>

this is assuming that you have your tabstop set to what you like, (so for the OP it would be ts=4)

I learned this from <a href="http://vim.wikia.com/wiki/Fix_indentation" rel="noreferrer">http://vim.wikia.com/wiki/Fix_indentation</a> , which mentions 

<blockquote>
 In normal mode, typing gg=G will reindent the entire file. This is a special case; = is an operator. Just like d or y, it will act on any text that you move over with a cursor motion command. In this case, gg positions the cursor on the first line, then =G re-indents from the current cursor position to the end of the buffer.

blocks|key|2804974|text|我使用了这个正则表达式(它使前导空格的数量加倍)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2804975|%25s;%5E$\s\%2B$;\=repeat('+',+len(submatch(0))*2);g|code-block|syntax|javascript|2804976|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Similar (but somewhat simpler) to cforbish's answer, this regex will duplicate the leading spaces

<pre><code>:%s/^$ \+$/\1\1
</code></pre>

<hr>

Or you can use this other regex to transform 2-spaces into 4-spaces, preserving single spaces (and odd amounts in general)

<pre><code>:%s/^$\( $\+\)/\1\1
</code></pre>

That is,

<ul>
<li>1 space ⇢ 1 space</li>
<li>2 spaces ⇢ 4 spaces</li>
<li>3 spaces ⇢ 5 spaces</li>
<li>4 spaces ⇢ 8 spaces</li>
</ul>

<pre><code>command! -range=% Format :&lt;line1&gt;,&lt;line2&gt;s/^\s*/&amp;&amp;

Just type <code>:Format</code>.

With visual selection, this only formats the selected lines.

Without visual selection, this formats the whole file.

This is a variant of the regex based answers.

I have a bash script in my local bin directory that will double the amount of whitespace at the start of a line. Input can be stdin or a file:

<pre><code>$ cat ~/bin/dblsp
#!/bin/bash

file=${1--}

while IFS= read -r line; do
 echo "$line" | sed 's/\s*/&amp;&amp;/'
done &lt; &lt;(cat -- "$file")
</code></pre>

I use this within vim by visually selecting a line and issuing the following command:

<pre><code>:'&lt;,'&gt;!dblsp
</code></pre>

This saves me the need to type (or remember) the regex.

I also use it in maps like the following:

<pre><code>nnoremap &lt;leader&gt;] `[V`]!dblsp&lt;CR&gt;
</code></pre>

which will apply it to a block of recently pasted text. I usually use the following map to paste rather than <code>:set paste</code>

<pre><code>nnoremap &lt;leader&gt;p :r !xclip -o&lt;CR&gt;
</code></pre>

My usual workflow is:

<ul>
<li>select code snippet (eg the <a href="https://www.terraform.io/docs/providers/google/r/storage_bucket.html" rel="nofollow noreferrer">example code</a> on this page is 2 spaces but I want 4) </li>
<li>paste code snippet (,p)</li>
<li>change spacing (,])</li>
</ul>

or simply changing the indent on yanked blocks pasted from another buffer.

I've some codes copied from the Internet that have 2-space indenting and I want to change it into 4-space indenting. I wonder if there is a short vim routine to accomplish the task without having to write vim script? Here is how I'm currently doing it with an HTML file:
<ul>
<li>Record a macro</li>
<li>Go to the beginning of a line</li>
<li>Visual select all whitespaces until the first occurrence of &quot;&lt;&quot;</li>
<li>Yank and paste all whitespaces (basically to double them)</li>
<li>Replay the macro till the end of the file</li>
</ul>
In short <code>qa0vt&lt;yp&lt;esc&gt;jq</code>
<h1>Pitfalls:</h1>
The macro fails for a blank line or a line that doesn't start with &quot;&lt;&quot;. And I have no idea how to extend this solution to non-HTML file.
