寻找一种将图像二进制文件转换为yaml的简单方法

Question

如何将大量小型网站图像文件作为 yaml 与其余代码一起存储在 git 中？希望避免在 git 中出现二进制文件。

到目前为止我已经手动完成了此操作。寻找一个 Python 脚本，我可以通过构建过程进行调整，将其转换为发送以获取，并在拉取后对其进行解码。

将要转换为 yaml 的扩展文件与以下脚本一起放入 ./files 目录中。然后运行：

./convert.py ext2yaml png

要从 yaml 运行检索这些文件：

./convert.py yaml2ext

转换.py

#!/usr/bin/env python3

import base64
import sys
import os
import yaml
import time

filesdir = "files"
yamlfile = (filesdir + "/inventory.yaml")


def setup():
    os.popen('mkdir -p ' + filesdir)
    check_file = os.path.isfile(yamlfile)
    if check_file == False:
        os.popen('touch ' + yamlfile)
        time.sleep(1)    
    try:
        errmsg = "\n  Missing arguments: Expected either ext2yaml followed by a file extention or just yaml2ext\n\n\
