# Проект "Вычислитель отличий"

## Описание
В рамках данного проекта необходимо реализовать утилиту для поиска отличий в конфигурационных файлах.

## Возможности утилиты:

- Поддержка разных форматов
- Генерация отчета в виде plain text, pretty и json

##Пример использования:

```
$ gendiff --format pretty first.json second.json

{
    common: {
        setting1: Value 1
      - setting2: 200
        setting3: true
      - setting6: {
            key: value
        }
      + setting4: blah blah
      + setting5: {
            key5: value5
        }
    }
    group1: {
      + baz: bars
      - baz: bas
        foo: bar
    }
  - group2: {
        abc: 12345
    }
  + group3: {
        fee: 100500
    }
}
```
