Ok, this seems to work. In my example, the contents of a given tiddler
(MyReductionText) are replaced with their reduced subset when the button is
pushed.
First the regular macro stuff:
\define tmp2()
<<reduce """$(mytext)$""">>
\end
<$set name="mytext" value={{MyReductionText!!text}}>
<<tmp2>>
<$button>
<$action-setfield
$tiddler="MyReductionText"
text=<<tmp2>> />
<$action-navigate $to="MyReductionText"/>
Modify and Go to Reduction Text
</$button>
</$set>
And then the javascript macro. Remember that the macro has to have
content-type set to applicaton/javascript with an additional field
"module-type" with value "macro".
/*\
title: $:/Macro/reduce.js
type: application/javascript
module-type: macro
This is a macro finds and returns all unique words in a given string of
text
\*/
(function(){
/*jslint node: true, browser: true */
/*global $tw: false */
"use strict";
exports.name = "reduce";
exports.params = [ { name: "text" } ];
/*
Run the macro
*/
exports.run = function(text) {
if(!text) text = "mytext";
var araWords = text.toLowerCase().replace( /\W/g," ").split(" ") ;
var mapWords = {} ;
var araReduced = [];
araWords.forEach(function (x) {
if (!mapWords[x]) {
araReduced.push(x);
mapWords[x] = true;
}
});
/*
*/
return araReduced.sort().reverse().join(" ") ;
};
})();
