Оправдано :) Не искам да прозвучи като заяждане, по-скоро като въпрос относно форматирането. Пиша на Sublime. Там всичко изглежда наред. Като копирам кода във формата на сайта трябва отново да подравнявам много от нещата. Къде е проблема?

@Милен, за Sublime ти препоръчвам тези неща:

  1. Сложи си опцията "draw_white_space": "all" в настройките на редактора.
  2. Инсталирай си плъгин, който ти показва trailing whitespace. Ако имаш Package Control, потърси плъгин, който се казва "TrailingSpaces" или нещо сродно. Ако нямаш Package Control, задължително си инсталирай.

  3. Увери се, че syntax specific настройките за Ruby (има го в менюто), имат следните две опции вътре:

     "tab_size": 2,
 "translate_tabs_to_spaces": true,
