Description

The computer of the differences is a program that determines the difference between the two data structures. This is a popular task, for the solution of which there are many online services, for example, jsondiff. A similar mechanism, for example, is used in the output of tests or in automatic monitoring of changes in configuration files.

Utility opportunities:

1. Support for different input formats: yml(yaml), json

2. Generation of the report in the form of plain text, stylish and json

Install

git clone https://github.com/sergeikuz/python-project-50
cd python-project-50
make setup

They are launched with simple commands:*

usage: gendiff [-h] [-f {stylish,plain,json}] first_file second_file

Compares two configuration files and shows a difference.

positional arguments:
  first_file
  second_file

options:
  -h, --help            show this help message and exit
  -f {stylish,plain,json}, --format {stylish,plain,json}
                        set format of output, you can choose formats: stylish, plain, json, (default format: stylish)

gendiff tests/fixtures/file1.yml tests/fixtures/file2.yml
gendiff -f plain tests/fixtures/file1.yml tests/fixtures/file2.yml
gendiff --format plain tests/fixtures/file1.json tests/fixtures/file2.json
gendiff --format json tests/fixtures/file1.json tests/fixtures/file2.json

✏️*Make sure that you have Python version 3.10 or higher installed.

Examples of teams for different output formats:

1. Stylish style: *Compares two configuration files and shows a difference in stylish format.

*stylish is default format
gendiff tests/fixtures/file1.yml tests/fixtures/file2.yml
gendiff -f stylish tests/fixtures/file1.yml tests/fixtures/file2.yml
gendiff --format stylish tests/fixtures/file1.json tests/fixtures/file2.json
gendiff --format stylish tests/fixtures/file1.json tests/fixtures/file2.json

2. Plain style: Compares two configuration files and shows a difference in plain format.

gendiff -f plain tests/fixtures/file1.yml tests/fixtures/file2.yml
gendiff --format plain tests/fixtures/file1.json tests/fixtures/file2.json

3. Json style: Compares two configuration files and shows a difference in json format.

gendiff -f json tests/fixtures/file1.yml tests/fixtures/file2.yml
gendiff --format json tests/fixtures/file1.json tests/fixtures/file2.json

How to find differences between two files:

Place two files that you want to compare in the tests/fixtures folder. Follow the team to search for differences:

gendiff -f plain tests/fixtures/file1.json tests/fixtures/file2.json

Replace file1.json and file2.json with your files

Good luck and have a fun! 🤚
