Layout/IndentHeredoc with wrong output

[daixiang0]

My ruby code is as below:

    stdout = <<~END  # i am sure this line has aligned, 4 spaces at the beginning
2017-03-22 09:28:24 sudo python width_and_depth_tests.py
Width test: PASSED
Depth test: FAILED
END

Rubpcop output is:

C: Layout/IndentHeredoc: Use 2 spaces for indentation in a heredoc by using <<~ instead of <<~.

So I add 2 spaces for 3 lines like below:

    stdout = <<~END  # i am sure this line has aligned
  2017-03-22 09:28:24 sudo python width_and_depth_tests.py
  Width test: PASSED
  Depth test: FAILED
END

Still same output, then i read the doc and it align with <<~, then i try and also fail.
I think the output is not clear or even wrong.

This cop says this code should be aligned like the following.

    stdout = <<~END
      2017-03-22 09:28:24 sudo python width_and_depth_tests.py
      Width test: PASSED
      Depth test: FAILED
END

The 2 space means 2 space * indentation level.
For example:

    stdout = <<~END # This line is indented by 2 * 2 space
      2017-03-22 09:28:24 sudo python width_and_depth_tests.py # This line is indented by 2 * 3 space (+1 level)
      Width test: PASSED
      Depth test: FAILED
END

Thanks, i misunderstand it.

But If i do need a blank in the beginning of EOF iike:

<<~EOF

  Hi!
EOF

How to fix this cop？

[pocke]

Hmm, It is a bug of this cop.
Currently this cop adds an offense for the code, but I think this cop should not add offense.

Let's reconsider the message in this case too: … by using <<~ instead of <<~.

[daixiang0]

I think so, this message may make people confused.
