The redirect means, that there is a special check in the code that handles the request. .. see: line 947 in the above link. > I could imagine that what was presented as a shadow tid was really > something like a *transclusion* presenting the JSON fields from the > plugin via a template... > as seen above ... it's a separated private memory, that can only be reached with an API call. > but if this was the case then I think we'd have generally more powerful > JSON features... > JSON means ... JavaScript Object Notation <http://www.json.org/>. A JS object is created, when ever you say: var mytiddlers = {}; In the case of shadow tiddlers its similar to mytiddlers[title].tiddler which is also called a hashmap <https://en.wikipedia.org/wiki/Hash_table>. Hashmaps can be used for fast "database" lookups. So you can see, that JSON is "native" in javascript, with some special twists. We have very powerfull tools, to deal with JSON. .. They are just not exposed directly to the users. ... We have "data-tiddlers", which let you deal with basic JSON objects, without starting js programming. ... If you need to go deeper, you need to create js-macros, because that's the next step. hope that helps. have fun! mario -- You received this message because you are subscribed to the Google Groups "TiddlyWikiDev" group.
