Just quickly wanted to say that I absolutely LOVE that we now have a good set of filter operators for JSON data handling. I use tiddlywiki mainly for managing ttrpg campaigns, and have always dreamed of being able to use JSON for more fine-grained data handling.
However, I will continue to longingly wait for some sort of array manipulation filter operators, as these are not yet present (see issue #7840).
(I definitely will start using JSON for real in my ttrpg tiddlywikis now, and will for the time being use a “poor mans’s substitute” for JSON arrays, as my use of arrays would be limited to storing a series of alphanumerical strings in them. My intent, therefore, is to cobble together some tool manipulating TW “title lists”; these can then be transferred to and from JSON strings with the jsonset and jsonget filter operators…)
