Patchdiff 🔍

基于rfc6902，此库提供了一个简单的API来生成由列表、集合、元组和字典组成的复合Python数据结构之间的双向差异。这些差异符合jsonpatch规范，并可选择序列化为JSON格式。Patchdiff还可以用于将补丁列表应用到对象上，可以是原地或输入的深拷贝。

安装

pip install patchdiff

快速入门

from patchdiff import apply, diff, iapply, to_json

input = {"a": [5, 7, 9, {"a", "b", "c"}], "b": 6}
output = {"a": [5, 2, 9, {"b", "c"}], "b": 6, "c": 7}

ops, reverse_ops = diff(input, output)

assert apply(input, ops) == output
assert apply(output, reverse_ops) == input

iapply(input, ops)  # apply in-place
assert input == output

print(to_json(ops, indent=4))
# [
#     {
#         "op": "add",
#         "path": "/c",
#         "value": 7
#     },
#     {
#         "op": "replace",
#         "path": "/a/1",
#         "value": 2
#     },
#     {
#         "op": "remove",
#         "path": "/a/3/a"
#     }
