The trouble with the previous approach of storing several settings in a single data tiddler was that it made it hard to introduce new settings. Users who already have a custom copy of the settings/metrics tiddler wouldn’t get the default settings. The new approach uses individual tiddlers for each setting. This commit also introduces a new theme tweak for the cutoff width for switching between responsive views.

title: DataTiddlers
|
|
|
|
Data tiddlers provide a way to access blocks of [[JSON]] data within the `text` field of a tiddler.
|
|
|
|
//The implementation of data tiddlers is preliminary, with some intentional limitations.//
|
|
|
|
! Data tiddler format
|
|
|
|
A native data tiddler must have:
|
|
|
|
* The ContentType field `type` set to `application/json`
|
|
* Valid JSON data in the `text` field
|
|
|
|
For example, the [[history list|$:/HistoryList]] tiddler is a data tiddler.
|
|
|
|
Other tiddler types with alternative formats can also be parsed to yield a block of data that behaves like a data tiddler.
|
|
|
|
!! Tiddler dictionary format
|
|
|
|
The tiddler dictionary format is an alternative syntax for data tiddlers:
|
|
|
|
* The ContentType field `type` is set to `application/x-tiddler-dictionary`
|
|
* The `text` field consists of one or more lines of the form `<name>:<value>`
|
|
|
|
For example, palettes such as the [[default Vanilla palette|$:/palettes/Vanilla]] are tiddler dictionaries.
|
|
|
|
! Accessing data within data tiddlers
|
|
|
|
Currently, it is only possible to access the top level properties of the data using TextReference syntax.
|
|
|
|
For example, given a `application/json` tiddler containing:
|
|
|
|
```
|
|
{"a":"one","b":"two","c":"three"}
|
|
```
|
|
|
|
Or the equivalent tiddler dictionary of type `application/x-tiddler-dictionary`:
|
|
|
|
```
|
|
a:one
|
|
b:two
|
|
c:three
|
|
```
|
|
|
|
With either of those definitions `{{TiddlerTitle##b}}` would have the value `two`.
