Inconsistent indentation not detected

[johnvh]

As of dc7544f, using:

$ cat .rubocop.yml
IndentationWidth:
  Enabled: true

Then:

$ cat test_1.rb && rubocop test_1.rb
if foo
  do_bar
    do_baz
end
Inspecting 1 file
.

1 file inspected, no offences detected

$ cat test_2.rb && rubocop test_2.rb
if foo
    do_bar
  do_baz
end
Inspecting 1 file
C

Offences:

test_2.rb:2:1: C: Use 2 (not 4) spaces for indentation.
    do_bar
^^^^

1 file inspected, 1 offence detected

It looks to me like the IndentationWidth cop should catch this.

Actually, I'm not sure the intent of the IndentationWidth cop is to catch inconsistent indentation. Is there another cop that should catch this?

It's a known limitation of the IndentationWidth cop that it can't catch inconsistent indentation in all cases (only in begin..end blocks). Here's an excerpt from the specs:

    it 'registers an offence for bad indentation of a def body' do
      inspect_source(cop,
                     ['def test',
                      '    func1',
                      '     func2', # No offence registered for this.
                      'end'])
      expect(cop.messages)
        .to eq(['Use 2 (not 4) spaces for indentation.'])
    end

But if we want to add more consistency checking, then I guess this cop is where it should go.
