This cops checks if empty lines exist around the arguments of a method invocation.
Example:
# bad
do_something(
foo
)
process(bar,
baz: qux,
thud: fred)
some_method(
[1,2,3],
x: y
)
# good

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)

that should be replaced by

Example:
# bad - uses `DateTime` for current time

Time.now
# bad - uses `DateTime` for modern date
DateTime.iso8601('2016-06-29')
# good - uses `Date` for modern date

Hash methods.
Note: If you have an array of two-element arrays, you can put parentheses around the block arguments to indicate that you're not working with a hash, and suppress RuboCop offenses.
Example:
# bad
hash.keys.each { |k| p k }
hash.values.each { |v| p v }
hash.each { |k, _v| p k }
hash.each { |_k, v| p v }

- Read upRead up
- Create a ticketCreate a ticket
- 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
%i[foo bar baz]
