Class: RuboCop::Cop::Style::ElseAlignment
- Includes:
- AutocorrectAlignment, CheckAssignment
- Defined in:
- lib/rubocop/cop/style/else_alignment.rb
Overview
This cops checks the alignment of else keywords. Normally they should be aligned with an if/unless/while/until/begin/def keyword, but there are special cases when they should follow the same rules as the alignment of end.
