  puts 'hello'
 end
end

Checks that braces used for hash literals have or don't have surrounding space depending on configuration.

Example: EnforcedStyle: space

# The `space` style enforces that hash literals have
# surrounding space.

# bad
h = {a: 1, b: 2}

# good
h = { a: 1, b: 2 }

Example: EnforcedStyle: no_space

# The `no_space` style enforces that hash literals have
# no surrounding space.

# bad
h = { a: 1, b: 2 }

# good
h = {a: 1, b: 2}

         if ! o.keys.include?( :nosyntax )

Use %i or %I for an array of symbols.
Open

    task :all => [:ok, :wip]
Severity: Minor
Found in lib/tasks/cucumber.rake by rubocop

This cop can check for array literals made up of symbols that are not using the %i() syntax.

Alternatively, it checks for symbol arrays using the %i() syntax on projects which do not want to use that syntax.

Configuration option: MinSize If set, arrays with fewer elements than this value will not trigger the cop. For example, a MinSize of3` will not enforce a style on an array of 2 or fewer elements.

Example: EnforcedStyle: percent (default)

# good
%i[foo bar baz]

# bad
[:foo, :bar, :baz]

Example: EnforcedStyle: brackets

# good
[:foo, :bar, :baz]

# bad
%i[foo bar baz]

# good
array = [ a, b, c, d ]

# The `no_space` style enforces that array literals have
# no surrounding space.

# bad
array = [ a, b, c, d ]

Missing top-level class documentation comment.
Open

class ImageUploader < CarrierWave::Uploader::Base
Severity: Minor
Found in app/uploaders/image_uploader.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

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.

Useless assignment to variable - week.
Open

               week = indent / 7 + 1
Severity: Minor
Found in app/services/memo_service.rb by rubocop

This cop checks for every useless assignment to local variable in every scope. The basic idea for this cop was from the warning of ruby -cw:

assigned but unused variable - foo

Currently this cop has advanced logic that detects unreferenced reassignments and properly handles varied cases such as branch, loop, rescue, ensure, etc.

Example:

# bad

def some_method
  some_var = 1
  do_something
end

Example:

# good

def some_method
  some_var = 1
  do_something(some_var)
end
