Use nested module/class definitions instead of compact style. Open
class Setup::ProjectsController < PrivateController
- Read upRead up
- Exclude checks
This cop checks the style of children definitions at classes and modules. Basically there are two different styles:
Example: EnforcedStyle: nested (default)
# good
# have each child on its own line
class Foo
class Bar
end
end
Example: EnforcedStyle: compact
# good
# combine definitions as much as possible
class Foo::Bar
end
The compact style is only forced for classes/modules with one child.
Missing magic comment # frozen_string_literal: true
. Open
class Setup::ProjectsController < PrivateController

This cop is designed to help upgrade to after 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
after 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: always (default)
# 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
# ...
end
Useless assignment to variable - project_anchor
. Did you mean project
? Open
project_anchor = current_program.project_anchor || current_program.build_project_anchor
- Read upRead up

This cop checks for every useless assignment to local variable in every
scope.
The basic idea for this cop was from the warning of ruby -cw
:
assigned but unused variable - foo
Currently this cop has advanced logic that detects unreferenced reassignments and properly handles varied cases such as branch, loop, rescue, ensure, etc.
Example:
# bad
def some_method
some_var = 1
do_something
end
Example:
# good
def some_method
some_var = 1
do_something(some_var)
end
