Put empty method definitions on a single line. Open

- Read upRead up
- Exclude checks
This cop checks for the formatting of empty method definitions.
By default it enforces empty method definitions to go on a single
line (compact style), but it can be configured to enforce the end
to go on its own line (expanded style).
Note: A method definition is not considered empty if it contains comments.
Example: EnforcedStyle: compact (default)
# bad
def foo(bar)
end
def self.foo(bar)
end
# good
def foo(bar); end
def foo(bar)
# baz
end
def self.foo(bar); end
Example: EnforcedStyle: expanded
# bad
def foo(bar); end
def self.foo(bar); end
# good
def foo(bar)
end
def self.foo(bar)

Checks for if and unless statements that would fit on one line

Missing top-level class documentation comment. Open
class ApplicationLettersController < ApplicationController
- Read upRead up
- Exclude checks
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

- Read upRead up
- Exclude checks
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 of
3` 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

Use the new Ruby 1.9 hash syntax. Open
return redirect_to new_profile_path, :alert => message
- Read upRead up
- Exclude checks
This cop checks hash literal syntax.
It can enforce either the use of the class hash rocket syntax or the use of the newer Ruby 1.9 syntax (when applicable).
A separate offense is registered for each problematic pair.
The supported styles are:
- ruby19 - forces use of the 1.9 syntax (e.g.
{a: 1}
) when hashes have all symbols for keys - hash_rockets - forces use of hash rockets for all hashes
- nomixedkeys - simply checks for hashes with mixed syntaxes
- ruby19nomixed_keys - forces use of ruby 1.9 syntax and forbids mixed syntax hashes
Example: EnforcedStyle: ruby19 (default)
# bad
{:a => 2}
{b: 1, :c => 2}
# good
{a: 2, b: 1}
{:c => 2, 'd' => 2} # acceptable since 'd' isn't a symbol
{d: 1, 'e' => 2} # technically not forbidden
Example: EnforcedStyle: hash_rockets
# bad
{a: 1, b: 2}
{c: 1, 'd' => 5}
# good
{:a => 1, :b => 2}
Example: EnforcedStyle: nomixedkeys
# bad
{:a => 1, b: 2}
{c: 1, 'd' => 2}
