Defined in:

Overview

Checks if the length of a module exceeds some maximum value. Comment lines can optionally be ignored. The maximum allowed length is configurable.

You can set constructs you want to fold with ‘CountAsOne`.

Available are: ‘array’, ‘hash’, ‘heredoc’, and ‘method_call’. Each construct will be counted as one line regardless of its actual size.

Examples:

CountAsOne: [‘array’, ‘hash’, ‘heredoc’, ‘method_call’]


module M
  ARRAY = [         # +1
    1,
    2
  ]

  HASH = {          # +1
    key: 'value'
  }

  MSG = <<~HEREDOC  # +1
    Heredoc
    content.
  HEREDOC

  foo(              # +1
    1,
    2
  )
end                 # 4 points
