XF 2.2 What is 'templateOverrides' in $viewParams and how does it work practically?

[Earl]

I've seen this "templateOverrides' thing in many places such as
Pub\Controller\Thread actionIndex, edit,
Pub\Controller\Forum\actionForum etc

And I see a template name in its value when the debugger is running on a question thread.

I've been trying to understand the mechanism here for a week and still, I have no clue about what exactly doing it.

I feel like it has something to do with new template extensions, but what exactly happening here?

I noted this when I try to add a template modification to the thread_list_macros template.
I have added a new function to make suggestions for discussions, and vote on these suggestions, And I was going to modify the thread_list_macros template and add a font awesome icon next to the watched icon, then again I noted this <xf:extension name="before_status_state"></xf:extension> extension has located right where I want to put my own custom font-awesome icon that indicates the discussion has suggestions.

Am I supposed to extend this using this template extension? or just use a find and replace simple template mod?

If I have to extend the template, creating a sub template is not enough, right? I have to put it on PHP code too, where exactly that code is located in PHP?

Calling different template/macro based on thread type. It comes from ThreadType Handler. Go to src/XF/ThreadType and review that directory. If you are going to extend functionality/view for a particular thread type, do it in the thread type handler system if possible. I remember some methods in there related to defining FA icons.

oh my! This thing was so tricky to understand, but eventually, it looks simpler than it used to be.

I'm gonna summarize this for people who are trying to understand.
