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
# good
foo_bar = 1
Example: EnforcedStyle: camelCase
# bad
foo_bar = 1
# good
fooBar = 1
Missing top-level class documentation comment. Open
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
# ...
end
