No cop checking for indentation of parameters?

[bquorning]

Checked on the latest master of RuboCop (0f260a6), this file produces no warnings:

# encoding: utf-8
def x(
    a: 1,
b: 2)
  puts a, b
end

def y(
    a,
b)
  puts a, b
end

The indentation is clearly wrong, but what would be the correct indentation?

def y(
      a,
      b
     )
  puts a, b
end

# or

def y(
  a,
  b
)
  puts a, b
end

# or

def y(a,
      b)
  puts a, b
end

Thanks for the reminder. 😄 Well, first of all, they should of course be aligned. We should add that check to the duties of Style/AlignParameters.

About the parentheses, we're already checking in Style/ClosingParenthesisIndentation that ") [is indented] the same as the start of the line where ( is" or that the parentheses are aligned if there's no line break inside the opening parenthesis. We could perhaps add some checking for symmetry. If one parenthesis (or curly brace or square bracket) has a line break on the inside, then the other one should have it too.
