Title: Can "Empty String" available in virtual tags?
Post by: dudas on April 17, 2021, 08:30:45 PM
First of all, I am sorry that I am not good at English(Cause I'm Korean). :'(  :'(
I don't know if you can understand what I'm saying, It's my first time to post in English Forum.

So, I'm trying to make Virtual Tags but I have an issue.
I made an Virtual Tags to separate Album's main Artist and featured Artist(I used Guest Artist)
I named "Separate" to this Virtual tags.


$IsNull(<Artist: Guest>," "," (feat. "<Artist: Guest>")")

It's fine when Guest Artist exists

But If there's no Guest Artist, This Virtual tags makes "Unknown Separate" Instead of "Empty String" that I want.

I uses Alternatives Virtual Tags

$IsNull(<Artists: Guest>,.," (feat. "<Artists: Guest>")")

But I want "Empty String",not "dot"

Can I make "Empty String" after <Artist: Guest>?
Please let me know how make Empty String.

Thank you for reading.

Welcome to the forum dudas.

I'll admit I didn't look at the post in great detail (and why the giant and alternating font sizes?) but I am wondering why you use a dot?, and I notice you are using some unnecessary brackets.

instead of
$IsNull(<Artists: Guest>,.," (feat. "<Artists: Guest>")")

this would probably work better
$IsNull(<Artists: Guest>,,<Artists: Guest>)

But this has left out the 'feat' part, and perhaps it doesn't achieve what you want exactly?
But hopefully this was some useful information for you to proceed.

Ha ha that's why I skipped right past this post the first time!

I think he wants it to show up like " (feat. ARTISTNAME)" after the title and that's why the brackets.

I think the problem with the original formula was the " " after the first comma and that this should work.
$IsNull(<Artists: Guest>,," (feat. "<Artists: Guest>")")
