hackmd image backup

README.md

hackmd 用的圖床 imgur 要清掉舊圖了
怕 hackmd 文件裡面的圖全都被清光 所以來備份一下

Steps

1. 設定 > 筆記設定 > 備份 > 下載所有筆記
2. 解壓縮
3. 把 image.py 搬進去同個資料夾
4. 執行 image.py
5. wget -i url.txt 來下載所有圖片

image.py

import glob
import re
f = []
for fn in glob.glob("*.md"):
    with open(fn, encoding="utf-8") as md:
        content = md.read()
        urls = re.findall("(https\://i\.imgur\.com/\w+\.(?:png|jpg|gif))", content)
        if urls:
            f += urls

with open("url.txt", "w") as wf:
    wf.writelines(l + "\n" for l in f)
