讓 AI 把手動處理變自動

目前我的網站是使用 WordPress 架設，並套用了一個佈景主題。不過裡面有些風格和設計我不太喜歡，想要自己調整。

一開始，我是透過手動修改程式碼的方式來調整，步驟如下：

Bash

cd /var/www/stackoverflow/wp-content/themes/gutenshop

1. 移除關於作者的區塊

編輯 single.php，刪除第 39 到 52 行的 PHP 程式碼：

PHP

// About the author start
echo '<div class="about-the-author">';
echo '<div class="grid-x grid-padding-x">';
echo '<div class="large-2 medium-3 small-12 cell">';
echo get_avatar( get_the_author_meta( 'ID' ), 100 );
echo '</div>';
echo '<div class="large-10 medium-9 small-12 cell">';
echo '<h3>';
echo esc_html('About the author','gutenshop');
echo '</h3>';
echo nl2br(get_the_author_meta('description'));
echo '</div>';
echo '</div>';
echo '</div>';
// About the author end

2. 修改日期顯示格式

將原本的 F j, Y 格式，全部改為 Y-m-d 格式。

修改 single.php 與 template-parts/content-excerpt.php：

• 原本的程式碼：PHPecho esc_html(get_the_date('F j, Y'));
• 修改後的程式碼：PHPecho esc_html(get_the_date('Y-m-d'));

3. 隱藏文章發表者資訊

編輯 template-parts/content-search.php 與 template-parts/content.php，將顯示發表者的函式註解掉：

• 原本的程式碼：PHPguten_shop_posted_by();
• 修改後的程式碼：PHP//guten_shop_posted_by();

4. 移除日期前方的文字

編輯 inc/template-tags.php，把原本顯示的 Posted on 字樣拿掉：

• 原本的程式碼：PHPesc_html_x( 'Posted on %s', 'post date', 'gutenshop' ),
• 修改後的程式碼：PHPesc_html_x( '%s', 'post date', 'gutenshop' ),

雖然手動修改可以達到效果，但每次佈景主題更新後，這些修改就會被覆蓋，又得重新來過一遍，非常麻煩。

於是，我把上面這些手動修改的步驟和需求直接貼給 AI ，並加上一句：

幫我產生 patch script

沒想到 AI 馬上就寫好了一個 Python 自動化腳本，把上面所有檔案的修改邏輯全部寫進去。

以後佈景主題更新時，我只要在終端機執行這個腳本，一秒就能自動完成所有的改版與修正，真的非常方便！
