Missing top-level class documentation comment.
Open

  class MarkdownHandler
Severity: Minor
Found in config/initializers/markdown_handler.rb by rubocop

This cop checks for missing top-level documentation of classes and modules. Classes with no body are exempt from the check and so are namespace modules - modules that have nothing in their bodies except classes, other modules, or constant definitions.

The documentation requirement is annulled if the class or module has a "#:nodoc:" comment next to it. Likewise, "#:nodoc: all" does the same for all its children.

Example:

# bad
class Person
  # ...
end

# good
# Description/Explanation of Person class
class Person
  # ...
end

Open

  #config.assets.compress = true
Severity: Minor
Found in config/environments/production.rb by rubocop

This cop 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.

Example:

# bad
#Some comment

# good
# Some comment

%w-literals should be delimited by [ and ].

Rails.application.config.assets.precompile += %w( glyphicons-halflings.png glyphicons-halflings-white.png )
Severity: Minor
Found in config/initializers/assets.rb by rubocop

This cop enforces the consistent usage of %-literal delimiters.

Specify the 'default' key to set all preferred delimiters at once. You can continue to specify individual preferred delimiters to override the default.

Example:

# Style/PercentLiteralDelimiters:

#     default: '[]'
#     '%i':    '()'

# good
%w[alpha beta] + %i(gamma delta)
