Defined in:

Overview

This cop checks the indentation of the right hand side operand in binary operations that span more than one line.

The `aligned` style checks that operators are aligned if they are part of an `if` or `while` condition, a `return` statement, etc. In other contexts, the second operand should be indented regardless of enforced style.

Examples:

EnforcedStyle: aligned (default)

# bad
if a +
    b
  something &&
  something_else
end

# good
if a +
   b
  something &&
    something_else
end

EnforcedStyle: indented

# bad
if a +
   b
  something &&
  something_else
end

# good
if a +
    b
  something &&
    something_else
end
