Is this possible/how do I?

Is this possible/how do I?

[Arthur Miller]

I am trying to font-lock a buffer and append the buffer content to
another buffer in different major mode (an org-buffer -> dired buffer).

My strategy was to open buffer in temp-buffer; insert content, activate
major mode, make it do it's own magic and then just copy text with
properties. Yeah, right; no free-lunch seems lilke.

The buffer does not seem to be font-locked despite major mode (org-mode)
enabled in that buffer. Is font-lock run only when text is displayed
i.e. when I switch-to-buffer?

1. Is there any way to get it to font-lock when not displayed?

Once both buffered are font-locked; if I turn off font-locking than
those text properties are not shown; seems like font-lock has it's own
set of text properties?

2. Do I have to copy those, or is there any other way to get those two
buffers to be displayed as font-lock, without a particual major mode
font-locking active?

I am sorry if this is too noob question, it is just lots to read; I have
been experimenting, but I am not really into the details of font locking
and text properties yet.

`font-lock-ensure`.

Does font-lock-ensure do what you need?

That was the very first thing I tried, there is a small program I posted where it didn't worked, few days ago. I get though some colors, but very little. Since then I have tried to activate org mode in that buffer but still with same result.

I probably misunderstand how it works. Do I need to activate theme engine too for that buffer or is it done automatically?

No, it does not, unfortunately. That was first thing I tried. I was manually switching to created buffer to see what it does.

I was following the find-file function and trying to switch parts of it out, and also to call org mode in the buffer myself, but I don't get nearly as coloured and processed output as if I get when calling org mode when I have buffer displayed or with find-file.

Seems like there are more things in the play, which I am not aware of yet.
