- Exclude checks
This cop (by default) checks for uses of the lambda literal syntax for single line lambdas, and the method call syntax for multiline lambdas. It is configurable to enforce one of the styles for both single line and multiline lambdas as well.
Example: EnforcedStyle: linecountdependent (default)
# bad
f = lambda { |x| x }
f = ->(x) do
x
end
# good
f = ->(x) { x }
f = lambda do |x|

Example: EnforcedStyle: lambda
# bad
f = ->(x) { x }
f = ->(x) do
x

# good
f = lambda { |x| x }
f = lambda do |x|

Missing top-level class documentation comment. Open
class AppDelegate
- 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

def tableView(table_view, cellForRowAtIndexPath: index_path)

This cop makes sure that all variables use the configured style, snake_case or camelCase, for their names.
Example: EnforcedStyle: snake_case (default)
# bad
fooBar = 1

foo_bar = 1
Example: EnforcedStyle: camelCase
# bad
foo_bar = 1
# good

Do not use space inside array brackets. Open
lambda { Motion::Blitz.dismiss } ]
- Read upRead up
- Exclude checks
Checks that brackets used for array literals have or don't have surrounding space depending on configuration.
Example: EnforcedStyle: space
# The `space` style enforces that array literals have
# surrounding space.
# bad
array = [a, b, c, d]
# good
array = [ a, b, c, d ]
Example: EnforcedStyle: no_space
# The `no_space` style enforces that array literals have
# no surrounding space.
# bad
array = [ a, b, c, d ]
# good
array = [a, b, c, d]
Example: EnforcedStyle: compact
# The `compact` style normally requires a space inside
# array brackets, with the exception that successive left
# or right brackets are collapsed together in nested arrays.
# bad
array = [ a, [ b, c ] ]
# good
array = [ a, [ b, c ]]
