Checks for uses of if with a negated condition. Only ifs without else are considered. There are three different styles:
- both
- prefix
- postfix
Example: EnforcedStyle: both (default)
# enforces `unless` for `prefix` and `postfix` conditionals
# bad
if !foo
bar
end
# good
unless foo
bar
end
# bad
bar if !foo
# good
bar unless foo
Example: EnforcedStyle: prefix
# enforces `unless` for just `prefix` conditionals
# bad
if !foo
bar
end
# good
unless foo
bar
end
# good
bar if !foo
Example: EnforcedStyle: postfix
# enforces `unless` for just `postfix` conditionals
# bad
bar if !foo
# good
bar unless foo
# good
if !foo

Use Hash#key?

. Open
if !feature_data.has_key? k
- Read upRead up
- Exclude checks
This cop (by default) checks for uses of methods Hash#haskey? and
Hash#hasvalue? where it enforces Hash#key? and Hash#value?
It is configurable to enforce the inverse, using verbose
method
names also.
Example: EnforcedStyle: short (default)

# good Hash#key? Hash#value?
Example: EnforcedStyle: verbose
# bad Hash#key? Hash#value?

Checks if uses of quotes match the configured preference.
Example: EnforcedStyle: single_quotes (default)
# bad
"No special symbols"
"No string interpolation"
"Just text"
# good
'No special symbols'
'No string interpolation'
'Just text'
"Wait! What's #{this}!"
Example: EnforcedStyle: double_quotes
# bad
'Just some text'
'No special chars or interpolation'
# good
"Just some text"
"No special chars or interpolation"

Redundant self
detected. Open
raise Togls::RuleMissingTargetType, "Rule '#{self.id}' of type '#{self.class}' is missing a required target type" if self.missing_target_type?
- 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

Missing magic comment # frozen_string_literal: true
. Open
module Togls
- Read upRead up
- Exclude checks
This cop is designed to help upgrade to Ruby 3.0. It will add the
comment # frozen_string_literal: true
to the top of files to
enable frozen string literals. Frozen string literals may be default
in Ruby 3.0. The comment will be added below a shebang and encoding
comment. The frozen string literal comment is only valid in Ruby 2.3+.
Example: EnforcedStyle: when_needed (default)
# The `when_needed` style will add the frozen string literal comment
# to files only when the `TargetRubyVersion` is set to 2.3+.
# bad
module Foo
# ...
end
# good
# frozen_string_literal: true
module Foo
# ...
end
Example: EnforcedStyle: always
# The `always` style will always add the frozen string literal comment
# to a file, regardless of the Ruby version or if `freeze` or `<<` are
# called on a string literal.
# bad
module Bar
# ...
end
# good
# frozen_string_literal: true
module Bar
# ...
end
Example: EnforcedStyle: never
# The `never` will enforce that the frozen string literal comment does
# not exist in a file.
# bad
# frozen_string_literal: true
module Baz
# ...
end
# good
module Baz

Avoid using Marshal.load
. Open
Marshal.load(@rules[rule_id])
- Read upRead up

This cop checks for the use of Marshal class methods which have potential security issues leading to remote code execution when loading from an untrusted source.
Example:
# bad
Marshal.load("{}")
Marshal.restore("{}")
# good
Marshal.dump("{}")
# okish - deep copy hack
Marshal.load(Marshal.dump({}))
