Create this tiddler and you have an nsort function which is exactly the
sort function from above. But as long as you don't mix strings with
numbers… So for sorting strings take "sort" for sorting pure number lists
take "nsort" but be prepared to get the same result as before when having
mixed lists.
/*\
title: $:/core/modules/filters/nsort.js
type: application/javascript
module-type: filteroperator
Filter operator for sorting

(function(){
/*jslint node: true, browser: true */
/*global $tw: false */
"use strict";
/*
Export our filter function
*/
exports.nsort = function(source,operator,options) {
var results;
if($tw.utils.isArray(source)) {
results = source;
} else {
results = [];
$tw.utils.each(source,function(element,title) {
results.push(title);
});
}
nsort(results,operator.operand,operator.prefix === "!");
return results;
};
})();
var nsort = function(titles,sortField,isDescending,isCaseSensitive) {
var wiki = $tw.wiki;
titles.sort(function(a,b) {
if(sortField !== "title") {
a = wiki.getTiddler(a).fields[sortField] || "";
b = wiki.getTiddler(b).fields[sortField] || "";
}
if(isNaN(a) || isNaN(b)) {
if(!isCaseSensitive) {
if(typeof a === "string") {
a = a.toLowerCase();
}
if(typeof b === "string") {
b = b.toLowerCase();
}
}
}
else {
a = a-0;
b = b-0;
}
if(a < b) {
return isDescending ? +1 : -1;
} else {
if(a > b) {
return isDescending ? -1 : +1;
} else {
return 0;
}
}
});
};
