XF 2.2 Minimal example of how to extend Thread

[ChristianA]

Hi there.
I need a minimal example of how to setup a Listener.php and an event listener to extend the Thread class in XF\Pub\Controller.
That's because I want to iterate all posts on the first page of a Thread to manipulate the html output in every post.

Background info: I can do that via template modification, but it is very ineffective to iterate every post via my own functions and classes. And the showstopper ultimatively is that I am not able to get other return vars than string from <xf:set>
So I need to extend Thread and iterate over every post item myself before output. So what is the perfect listener and hint for that? I did that on a previous Version of XF, but in 2.2 this is very new to me and the example demo is a bit more than I need - I just need to manipulate posts directly before rendering them.

Thanks in advance!

You can use the class extension for xf2 development instead of from the Listener file.

The question doesn't make much sense to me, maybe you could explain exactly what you want to to.

Btw:

<xf:set var="$bool" value="{{ true }}" />
<xf:set var="$int" value="{{ 1 }}" />
<xf:set var="$arr" value="{{ {"foo" : "bar", "int" : $int} }}" />
