I also want to work with indes and values. But I did not know how to do it
combining filters like you. Then i created a new filter cloning *
$:/core/modules/filters/indexes.js *and I modified it for obtain values,
the important changes are in bold.
/*\
values.js
type: application/javascript
module-type: filteroperator
Filter operator for returning the values of a data tiddler
\*/
(function(){
"use strict";
/*
Export our filter function
*/
exports.*values* = function(source,operator,options) {
var results = [];
source(function(tiddler,title) {
var data = options.wiki.getTiddlerDataCached(title);
if(data) {
$tw.utils.pushTop(results,Object.*values*(data));
}
});
return results;
};
})();
Now you can use it. [<dataTiddler>values[]] instead the *populate* macro
which is filtering the output of other filter.
