这里有一种测试核心补丁的方法#33300.6 通过Andew Ozz, 通过WP 4.5.2中的测试插件，尝试文本模式过滤器。
演示下面是一个删除线的示例，使用~
$init[\'wpsetextpattern_inline_patterns\'] = \'{
strong: { start: "*", end: "*", format: "bold" },
strong2: { start: "**", end: "**", format: "bold" },
em: { start: "_", end: "_", format: "italic" },
strikethrough: { start: "~", end: "~", format: "strikethrough" }
}\';
在测试插件中。其工作原理如下：

测试插件的结构是：
/plugins/custom-text-patterns/
custom-text-patterns.php
js/
plugin.js
文件所在位置：
custom-text-patterns.php:

plugin.js: 与修补程序合并
#33300.6, 用wpsetextpattern替换wpsetextpattern：
/**
* Text pattern plugin for TinyMCE
*
* @since 4.3.0
*
* This plugin can automatically format text patterns as you type. It includes two patterns:
* - Unordered list (`* ` and `- `).
* - Ordered list (`1. ` and `1) `).
*
* If the transformation in unwanted, the user can undo the change by pressing backspace,
* using the undo shortcut, or the undo button in the toolbar.
