Re: [tw] [TW5] How to make transcluded /generated with macro data tiddlers as JSONTiddlers?

2016-04-22 Thread Jeremy Ruston 
Hi Martian

Just to expand on Mario’s answer: the D3 plugin is little more than a tech demo 
to show how a third party library can be integrated with TiddlyWiki. In 
particular, the way that data is passed to it doesn’t easily permit the data to 
be created dynamically. I agree that the best way forwards for your use case is 
likely to involve improving the D3 widget itself.

Best wishes

Jeremy

[tw] [TW5] How to make transcluded /generated with macro data tiddlers as JSONTiddlers?

2016-04-21 Thread Martian 
Hello!
As I understand, to be able to get {{##datafield}} a tiddler have to be 
marked as 'application/json' type.

But since I mark a tiddler with this type then neither transclude {{}} nor 
macros <<>> is not working inside it.
And I am going to generate JSON content with a  macro. 

Is there any way to turn tiddler with macro/transclude content into 
JSONTiddler ?
