Не си поправяй стила в source control-а (тук), а в редактора ти. :)

Прегледай темата във форума и примерите, които обсъждаме там.

Не ми харесва как си форматирал извикването на collect. Ползваме do/end за многоредови болове. Даването на стойност на x не е нужно. Предпочитаме синонима map тъй като е по-често ползван.

Знанието за създаване на елементи и слагане на рамка го има на две места. Може ли да се пакетира на едно място? Може би Horizontal и Vertical не са толкова различни. На едното място пазиш елементите в String, а на другото в Array. Можеш ли да ги направиш по-консистентни? Така може би ще можеш да извлечеш общата им логика на едно място.

За жалост поправките в стила не ги забелязвам докато не пусна решението тук, защото на моя редактор табулациите(които се слагат автоматично при нов ред) са 4 интервала, а тук е 8.

Отколкото до забележките по кода, разбирам как може да се направи, но просто не разполагам с времето да ги поправя до крайния срок. Много жалко.
