-/** |
- * @fileoverview This is a simple template engine inspired by JsTemplates |
- * optimized for i18n. |
- * |
- * It currently supports three handlers: |
- * |
- * * i18n-content which sets the textContent of the element. |
- * |
- * <span i18n-content="myContent"></span> |
- * |
- * * i18n-options which generates <option> elements for a <select>. |
- * |
- * <select i18n-options="myOptionList"></select> |
- * |
- * * i18n-values is a list of attribute-value or property-value pairs. |
- * Properties are prefixed with a '.' and can contain nested properties. |
- * |
- * <span i18n-values="title:myTitle;.style.fontSize:fontSize"></span> |
- * |
- * This file is a copy of i18n_template.js, with minor tweaks to support using |
- * load_time_data.js. It should replace i18n_template.js eventually. |
