Overview

Checks whether comments have a leading space after the ‘#` denoting the start of the comment. The leading space is not required for some RDoc special syntax, like `#++`, `#–`, `#:nodoc`, `=begin`- and `=end` comments, “shebang” directives, or rackup options.

Examples:


# bad
#Some comment

# good
# Some comment

AllowDoxygenCommentStyle: false (default)


# bad

#**
# Some comment
# Another line of comment
#*

AllowDoxygenCommentStyle: true


# good

#**
# Some comment
# Another line of comment
#*

AllowGemfileRubyComment: false (default)


# bad

#ruby=2.7.0
#ruby-gemset=myproject

AllowGemfileRubyComment: true


# good

#ruby=2.7.0
#ruby-gemset=myproject

AllowRBSInlineAnnotation: false (default)


# bad

include Enumerable #[Integer]

attr_reader :name #: String
attr_reader :age  #: Integer?

AllowRBSInlineAnnotation: true


# good

include Enumerable #[Integer]

attr_reader :name #: String
attr_reader :age  #: Integer?

AllowSteepAnnotation: false (default)


# bad
[1, 2, 3].each_with_object([]) do |n, list| #$ Array[Integer]
  list << n
end

name = 'John'      #: String

AllowSteepAnnotation: true


# good

[1, 2, 3].each_with_object([]) do |n, list| #$ Array[Integer]
  list << n
end

name = 'John'      #: String
