Defined in:
lib/rubocop/cop/lint/end_alignment.rb

Overview

This cop checks whether the end keywords are aligned properly.

Three modes are supported through the ‘AlignWith` configuration parameter:

If it’s set to ‘keyword` (which is the default), the `end` shall be aligned with the start of the keyword (if, class, etc.).

If it’s set to ‘variable` the `end` shall be aligned with the left-hand-side of the variable assignment, if there is one.

If it’s set to ‘start_of_line`, the `end` shall be aligned with the start of the line where the matching keyword appears.

Examples:

@good
# keyword style
variable = if true
           end

# variable style
variable = if true
end

# start_of_line style
puts(if true
end)
