Hi @Diafwl,

yes currently file links need to start with an ! so the only working way àt the moment is ![[book.pdf]]. This is the default behavior if you drag & drop a file into a md document in obsidian.

I will take a look if I can implement the other formats as well.

but because of regex it does not capturing ![[book.pdf| Book Volume 1]] even if this one has ! renaming with | broking file links.

yes, aliases for files are not supported / implemented at the moment

[Diafwl]

if we change pdf regex to \!?(\[\[)(.*?.pdf)(\]\]) it will work with ! or without !.
i tested i little bit it seems does not broke anything.

looks good 👍 then only the alias part is missing, ideally I should move the obsidian linking part into the PerliteParsdown.php but this is a little bit more work

@Diafwl
This is a quick and dirty solution you can try. Just replace the pdf links section with these two:

	// pdf links with Alias
	$replaces = '<a class="internal-link" target="_blank" rel="noopener noreferrer" href="'.$path .'/'.'\\2">\\3</a>';
	$pattern = array('/(\!?\[\[)(.*?.pdf)\|(.*)(\]\])/');
	$content = preg_replace($pattern, $replaces ,$content);
	
	// pdf links without Alias
	$replaces = '<a class="internal-link" target="_blank" rel="noopener noreferrer" href="'.$path .'/'.'\\2">\\2</a>';
	$pattern = array('/(\!?\[\[)(.*?.pdf)(\]\])/');
	$content = preg_replace($pattern, $replaces ,$content);

I will check this again as soon I have some time and will make a new release

Yeah it works perfectly.

Thank you.
