Description

A Python package to generate a diff between two nested structures.

gendiff nested_node1.json nested_node2.json

Example input files are located at tests/fixtures.

Supports custom replacers and indent increments for the stylish (default) output:

gendiff nested_node1.json nested_node2.json --replacer  ⏐ --increment 2

{
⏐⏐common: {
⏐⏐⏐⏐node1: val 1
⏐⏐- node2: 200
⏐⏐⏐⏐node3: true
⏐⏐+ node5: got ya
⏐⏐⏐⏐node6: {
⏐⏐⏐⏐⏐⏐doge: {
⏐⏐⏐⏐⏐⏐- wow: 
⏐⏐⏐⏐⏐⏐+ wow: cool
⏐⏐⏐⏐⏐⏐}
⏐⏐⏐⏐- key: val
⏐⏐⏐⏐}
⏐⏐}
}

And the plain output format:

gendiff --format plain nested_node1.json nested_node2.json

Property 'common.node2' was removed
Property 'common.node5' was added with value: 'got ya'
Property 'common.node6.doge.wow' was updated. From '' to 'cool'
Property 'common.node6.key' was removed

The package works both with JSON and YAML files. The json output format shows what happened to each node (added, deleted, changed or unchanged):

Created during the Hexlet "Python developer" course without any mentoring.
