title: indexes Operator
type: text/vnd.tiddlywiki
caption: indexes
op-purpose: select all data properties of the input titles
op-input: a [[selection of titles|Title Selection]]
op-parameter: none
op-output: all the property names or indices contained in the input data tiddlers

Each input title is processed in turn, and is ignored if it does not denote a [[data tiddler|DataTiddlers]]. The list of property names is retrieved from the data tiddler (in no particular order) and then [[dominantly appended|Dominant Append]] to the operator's output.

Where a tiddler's [[content is JSON|JSONTiddlers]] with an array as its root, the <<.op indexes>> operator retrieves a selection of integer indices instead.
