Includes:
EndKeywordAlignment, OnMethodDef
Defined in:
lib/rubocop/cop/lint/def_end_alignment.rb

Overview

This cop checks whether the end keywords of method definitions are aligned properly.

Two modes are supported through the AlignWith configuration parameter. If it's set to start_of_line (which is the default), the end shall be aligned with the start of the line where the def keyword is. If it's set to def, the end shall be aligned with the def keyword.

Examples:


private def foo
end

Constant Summary collapse

MSG = 
'`end` at %d, %d is not aligned with `%s` at %d, %d'
