Actually there is a very simple method to achieve this:

<pre><code>{{ mylist | map('quote') | join(', ') }}
</code></pre>

The filter <code>map</code> iterates over every item and let <code>quote</code> process it. Afterwards you can easily <code>join</code> them together.

blocks|key|1251566|text|这将起作用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1251567|ip={{+'\"'+%2B+ip%7Cjoin('\",+\"')+%2B+'\"'+}}|code-block|syntax|javascript|1251568|一个自定义的过滤器插件也将工作。在ansible.cfg中取消注释filter_plugins并给它一个路径，我们在其中放置以下内容|1251569|def+wrap(list):
++++return+[+'"'+%2B+x+%2B+'"'+for+x+in+list]

class+FilterModule(object):
++++def+filters(self):
++++++++return+{
++++++++++++'wrap':+wrap
++++++++}|1251570|在一个名为core.py的文件中。像这样。然后您可以简单地使用|offset|length|1251571|ip%7Cwrap%7Cjoin(',+')|1251572|它应该生成逗号分隔的列表，每个ip都用引号包装。|1251573|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/ansible/ansible/tree/devel/lib/ansible/runner/filter_plugins^0|0|0|0|0|H|3|0|0|0|0^^$0|@$1|2|3|4|5|6|7|10|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|11|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|12|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|13|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|14|8|@]|9|@$M|15|N|16|1|17]]|A|$]]|$1|O|3|P|5|D|7|18|8|@]|9|@]|A|$E|F]]|$1|Q|3|R|5|6|7|19|8|@]|9|@]|A|$]]|$1|S|3|-4|5|6|7|1A|8|@]|9|@]|A|$]]]|T|$U|$5|V|W|X|A|$Y|Z]]]]

This will work :

<pre><code>ip={{ '\"' + ip|join('\", \"') + '\"' }}
</code></pre>

A custom filter plugin will also work. In ansible.cfg uncomment filter_plugins and give it a path, where we put this

<pre><code>def wrap(list):
 return [ '"' + x + '"' for x in list]

class FilterModule(object):
 def filters(self):
 return {
 'wrap': wrap
 }
</code></pre>

in a file called core.py. <a href="https://github.com/ansible/ansible/tree/devel/lib/ansible/runner/filter_plugins" rel="noreferrer">Like this</a>. Then you can simply use

<pre><code>ip|wrap|join(', ')
</code></pre>

And it should produce comma seperated list with each ip wrapped in quotes.

Use to_json filter. This will double quote every string of the list:
<pre><code>list_of_string | map(&quot;to_json&quot;)
</code></pre>
The problem with the &quot;quote&quot; filter is that it does not quote elements that dont need to be quoted from a bash perspective (no space in the string). But for windows commands sometimes strings must be quoted anyway.

I've developed a custom <code>wrap</code> filter

<pre><code>def wrap(value, wrapper = '"'):
 return wrapper + value + wrapper

class FilterModule(object):
 def filters(self):
 return {
 'wrap': wrap
 }
</code></pre>

As you can see wrapper is customizable and defaults to <code>"</code>

You can use it this way

<pre><code>ip={{ ip | map('wrap') | join(', ') }}
</code></pre>

Disclaimer: I'm a python and ansible newbie

blocks|key|2549870|text|我发现使用现有的Ansible最简单的方法是使用regex_replace。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2549871|{{+ip+%7C+map("regex_replace","(.%2B)","\'\\1\'")+%7C+join(',')}}|code-block|syntax|javascript|2549872|entityMap^0|O|D|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

I found the simplest way to do this with an existing Ansible filter is using <code>regex_replace</code>.

<pre><code>{{ ip | map("regex_replace","(.+)","\'\\1\'") | join(',')}}
</code></pre>

blocks|key|206507|text|你可以用regex_replace，f.e。在j2模板文件中：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|206508|(ip={{ip+%7C+map('regex_replace',+'(.*)',+"'\\1'")+%7C+join(',')}})|code-block|syntax|javascript|206509|如果你在一出戏里这样做，别忘了避开双引号。下面是一个完整的例子：|206510|-+hosts:+localhost

You can use <code>regex_replace</code>, f.e. in a j2 template file:

<pre><code>(ip={{ip | map('regex_replace', '(.*)', "'\\1'") | join(',')}})
</code></pre>

If you do this inline in a play, do not forget to escape the double quotes. Here is a full example:

<pre><code>- hosts: localhost
 gather_facts: no
 vars:
 ip:
 - 1.1.1.1
 - 2.2.2.2
 - 3.3.3.3
 ip_result: "{{ip | map('regex_replace', '(.*)', \"'\\1'\") | join(',')}}"
 tasks:
 - debug: msg="(ip={{ip_result}})"
 - copy: content="(ip={{ip_result}})" dest=./ip_result.txt
</code></pre>

Content of ip_result.txt:

<pre><code>$ cat ip_result.txt
(ip='1.1.1.1','2.2.2.2','3.3.3.3')
</code></pre>

I have very simple line in the template:

<pre><code>ip={{ip|join(', ')}}
</code></pre>

And I have list for ip:

<pre><code>ip:
 - 1.1.1.1
 - 2.2.2.2
 - 3.3.3.3
</code></pre>

But application wants IPs with quotes (ip='1.1.1.1', '2.2.2.2').

I can do it like this:

<pre><code>ip:
 - "'1.1.1.1'"
 - "'2.2.2.2'"
 - "'3.3.3.3'"
</code></pre>

But it is very ugly. Is any nice way to add quotes on each element of the list in ansible?

Thanks!

我在模板中有非常简单的行：ip={{ip|join(', ')}}我有ip的名单：ip: - 1.1.1.1 - 2.2.2.2 - 3.3.3.3但是应用程序需要带有引号的ip (ip='1.1.1.1'，'2.2.2.2')。我可以这样做：ip: - "'1.1.1.1'" - "'2.2.2.2'" - "'3.3.3.3'"但它很丑。在ansible中添加列表中每个元素的引号有什么好方法吗
