Using requireJS, jQuery and a unique template syntax, fill in text in an HTML document

compile.js

'use strict';

// "source" should be the name of a text file (the '.txt' extension is assumed, so leave it off),
//   formatted as follows:
/*

:css selector:
Text content for this element
::

:another css selector:
Text content for this other element
::

*/

define(['jquery'], function ($) {
    function getDictionary (source) {
        var dict = {};
        source = source.split('::');

        for (var index = 0; index < source.length; index++) {
            var keyVal = source[index].trim();
            var keyStart = keyVal.indexOf(':') + 1;
            var keyEnd   = keyVal.indexOf(':', keyStart);
            var key = keyVal.substr(keyStart, keyEnd - keyStart).replace(/[\n\r]+/g, '');
            var definition = keyVal.substr(keyEnd + 1).replace(/[\n\r]+/, '').replace(/[\n\r]+$/, '');
            
            dict[key] = definition;
        }

        return dict;
    }
    
    return function (source) {
        require(['text!' + source + '.txt'], function (source) {
            var dict = getDictionary(source);

            for (var selector in dict) {
                $(selector).text(dict[selector]);
            }
        });
