I am trying to convert these three rules into an advanced one:



Context: the first rule checks for url: identifiers I want to remove from finished fanfics, and the second two check for missing ao3/ffnet identifiers that I want to add to in-progress fanfics. If I see the icon, I then run my Cleanup: Fanfiction action chain to automagically do it.

I have this, which works (I changed a few things around):

program:
	status = $#fanficstatus;
	publisher = $publisher;
	ids = $identifiers;
	u = select(ids, 'url');
 	a = select(ids, 'ao3');
	f = select(ids, 'ffnet');

	if 
		u
		&& '(Archive of Our Own|Fanfiction.net)' in publisher  
		&& '(Completed|Abandoned|Oneshot)' in status
	then "metadata.png:"

	elif
		u
		&& a
		&& publisher = 'Archive of Our Own'
		&& status = 'In-Progress'
	then "metadata.png:"

	elif
		u
		&& f
		&& publisher = 'FanFiction.net'
		&& status = 'In-Progress'
	then "metadata.png:"

	fi

Except that && a and && f both specify "if these identifiers exist." How do I get it to instead specify "if these identifiers do not exist"?

Also, how would I specificy "if (A or F) exist" for the first part?

I see this part but I don't really understand how to make the syntax work

or_expression   ::= and_expression [ '||' and_expression ]*
and_expression  ::= not_expression [ '&&' not_expression ]*
not_expression  ::= [ '!' not_expression ]* | compare_exp
