@Tony Could you give some idea of how/why* It is going to be used in a context > where other wikitext cannot be introduced. ?* >
Explaining my specific use case would be quite complex as it is part of a much larger application. The filter I've described in this thread is a simpler one that presents an analogous issue, where you want to replace an input title with one if its field if that field exists, otherwise retain the original title. All without changing the list order. It could just as easily be get[parent] instead of get[caption] if that helps with conceptualizing the problem. There are plenty of general use cases where a filter needs to provide the necessary output independently of other wikitext. For example: - As input to a widget that accepts a filter attribute. - In a configuration tiddler that accepts a filter. See for instance $:/config/syncFilter or $:/core/ui/DefaultSearchResults. - As a filter meant to be used elsewhere via the subfilter[] operator - When trying to optimize refresh performance in a large and complex widget tree and wanting to use as few widgets as possible. I am interested in the challenge. > A good way to frame the constraints is that it should be possible to type the filter directly into the Filter tab in AdvancedSearch. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
