Use snake_case for method names. Open
def sortKeys
- Read upRead up
- Exclude checks
This cop makes sure that all methods use the configured style, snake_case or camelCase, for their names.
Example: EnforcedStyle: snake_case (default)
# bad
def fooBar; end
# good
def foo_bar; end
Example: EnforcedStyle: camelCase
# bad
def foo_bar; end
# good
def fooBar; end

Use each_key
instead of keys.each
. Open
@dSchema[:properties].keys.each do |yKey|
- Read upRead up
- Exclude checks
This cop checks for uses of each_key
and each_value
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 }
# good
hash.each_key { |k| p k }
hash.each_value { |v| p v }

return self
- Read upRead up
- Exclude checks
This cop checks for redundant return
expressions.
Example:
def test

end
def test

It should be extended to handle methods whose body is if/else or a case expression with a default branch.

Redundant self
detected. Open
@dDocument = self.getDefaultDocument()
- Read upRead up
- Exclude checks
This cop checks for redundant uses of self
.
The usage of self
is only needed when:
Sending a message to same object with zero arguments in presence of a method name clash with an argument or a local variable.
Calling an attribute writer to prevent an local variable assignment.
Note, with using explicit self you can only send messages with public or protected scope, you cannot send private messages this way.
Note we allow uses of self
with operators because it would be awkward
otherwise.
Example:
# bad
def foo(bar)
self.baz
end
# good
def foo(bar)
self.bar # Resolves name clash with the argument.
end
def foo
bar = 1
self.bar # Resolves name clash with the local variable.
end
def foo
%w[x y z].select do |bar|
self.bar == bar # Resolves name clash with argument of the block.
end
end
Prefer JSON.parse
over JSON.load
. Open
@dDocument = JSON.load(jDocument)
- Read upRead up
- Exclude checks
This cop checks for the use of JSON class methods which have potential security issues.
Autocorrect is disabled by default because it's potentially dangerous.
If using a stream, like JSON.load(open('file'))
, it will need to call
#read
manually, like JSON.parse(open('file').read)
.
If reading single values (rather than proper JSON objects), like
JSON.load('false')
, it will need to pass the quirks_mode: true
option, like JSON.parse('false', quirks_mode: true)
.
Other similar issues may apply.
Example:
# always offense
JSON.load("{}")
JSON.restore("{}")
# no offense
JSON.parse("{}")
Use alias
instead of alias_method
in a class body. Open
alias_method :pushAttr, :pushProp
- Read upRead up
- Exclude checks
This cop enforces the use of either #alias
or #alias_method
depending on configuration.
It also flags uses of alias :symbol
rather than alias bareword
.
Example: EnforcedStyle: prefer_alias (default)
# bad
alias_method :bar, :foo
alias :bar :foo
# good
alias bar foo
Example: EnforcedStyle: preferaliasmethod
# bad
alias :bar :foo
alias bar foo
# good
alias_method :bar, :foo
Do not use parentheses for method calls with no arguments. Open
@dSchema = dSchema || self.getDefaultSchema()
- Read upRead up
- Exclude checks
This cop checks for unwanted parentheses in parameterless method calls.
Example:
# bad
object.some_method()
# good
object.some_method

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