Default PDF link formatting with hotkey: not working (because I don't know how to code)

[RankkaApina]

I'm trying to automate a formatting for a pdf file link, one that I could use with a hotkey, but I'm missing something.

Basically, I'm trying to create a formatting that when I'm done would give me (PDF), where the PDF is the link. I.e. if I have a file link to a pdf, like [[this-is-my-file.pdf]], when I use my hotkey, it would create the following: ([[this-is-my-file.pdf|PDF]]). Preferably this would work so, that when I add the link and my cursor is just after the ]], I could hit the hotkey and I would get the formatting. Right now (because I'm still a noob when it comes to js & templater), I would need to select the link, which is fine if I can't make it work exactly as I'd like. However, currently even selecting the link is not working.

This is what I got (and I get there maybe multiple things wrong with my approach):

<%* 
selection = tp.file.selection();
(tp.file.selection())
position = editor.getCursor();
editor.setCursor({ line: position.line, ch: position.ch - 3})
|PDF
-%>

It gives me the following error in console:

Templater Error: Template parsing error, aborting. 
 editor is not defined

Any pointers/ways to fix this?

Here are two simpler options, either will work.

<%* 
let newLink = tp.file.selection().replace(']]', '|PDF]]');
tR += newLink;
-%>

<% tp.file.selection().replace(']]', '|PDF]]') %>

Doing what you originally set out to do is possible but more complicated, as you would need to get access to the active editor instance.

THANK YOU!!!
I even managed to add the parenthesis on my own (I feel accomplished right now 😆).

<%* 
let newLink = tp.file.selection().replace(']]', '|PDF]]');
tR += "("+newLink+")";
-%>
