一键更换所有图片格式

如题, 要求是把 旧格式的图片引用：
1
![](imageurl)
批量替换为 新主题格式：
1
{% image imageurl %}

Python实现

这种方式需要电脑中有Python环境, 虽然配置环境也比较简单, 但是还是需要一些门槛

注意修改脚本中的文件夹路径为自己的即可

import os
import re

# 要处理的文件夹路径，例如 Hexo 的 source/_posts
ROOT_DIR = "./source/_posts"

# 匹配旧格式：![](URL)
pattern = re.compile(r'!\[\]\((https://[^)]*)\)')

def replace_in_file(file_path):
    with open(file_path, "r", encoding="utf-8") as f:
        content = f.read()

    # 替换为新格式：{% image URL %}
    new_content = pattern.sub(r'{% image \1 %}', content)

    if new_content != content:
        with open(file_path, "w", encoding="utf-8") as f:
            f.write(new_content)
        print("Updated:", file_path)

def walk_dir(root):
    for root_dir, _, files in os.walk(root):
        for filename in files:
            if filename.endswith(".md"):
                full_path = os.path.join(root_dir, filename)
                replace_in_file(full_path)

if __name__ == "__main__":
    walk_dir(ROOT_DIR)
    print("Done.")
