許多人在 WordPress 分享程式碼，在分享程式碼時，希望程式碼像在程式編輯器一樣，可以高亮度語法顯示。而程式碼高亮度語法顯示的工具很多，今天來介紹「WP-GeSHi-Highlight」這個工具，這個套件是師承 WP-Syntax，而且支援超多語法的，如果要分享程式碼，這個工具可以試看看。
◎◎Wordpress 套件小檔案◎◎
■ 套件名稱：WP-GeSHi-Highlight
■ 套件版本：1.3.1
■ 語言介面：英文
■ 套件性質：免費

■ 套件名稱：WP-GeSHi-Highlight
■ 套件版本：1.3.1
■ 語言介面：英文
■ 套件性質：免費
■ 官方網站：https://www.inote.tools/wp-geshi-highlight/
WP-GeSHi-Highlight 的用法如下，其中 lang=php 代表語法是 php，可以換成其它語言，詳見官方所列出的「支援語言列表」。而 line=”1″ 代表要顯示行號，行號從 1 開始。
<pre lang="php" line="1">
</pre>
而底下是展示範例，是以 Java 的程式碼來做展！
