Вопросы про diff

Находит самые длинные общие последовательности между двумя текстами, затем подсвечивает добавленное, удалённое или изменённое. Тот же алгоритм, что использует Git под капотом.

Зелёный = добавлено (есть в новом, нет в старом). Красный = удалено (было в старом, нет в новом). Без подсветки = не изменилось. Изменения на уровне символов подсвечиваются внутри строк.

Работает с любым текстом. Код, конфиги, markdown, SQL — неважно. Построчное и посимвольное сравнение.
