That's close to what I was trying to do, though now it causes tags to display unsplit.
Hopefully this explains better what I'm trying to do:
Tags: Fiction.Animals.Cats, Fiction.Mystery.Cozy Mystery
Results: Fiction, Animals, Cats, Mystery, Cozy Mystery
(It'd also be nice if this was also sorted alphabetically, but I'm not
that fussy.)
Tags: Documentation and Manuals.Video Games
Results: Documentation and Manuals
Tags: Fanfiction.Crossover, Fanfiction.Half-Life & Portal, Fanfiction.Mass Effect
Results: Fanfiction
Tags: Fanfiction.Crossover, Fiction.Animals.Cats
Results: Fanfiction, Fiction, Animals, Cats
My own solution to this is pretty much this, which works but is a bit clumsy:
Code:
{tags:'list_difference(re($, '\.', ', '), 'Video Games, Strategy Guides, Crossover, Half-Life & Portal, Mass Effect', ',')'}
