Classes and modules are the units of reuse and release. It is therefore considered good practice to annotate every class and module with a brief comment outlining its responsibilities.
Example
Given
class Dummy
# Do things...
end
Reek would emit the following warning:
test.rb -- 1 warning:
[1]:Dummy has no descriptive comment (IrresponsibleModule)
Fixing this is simple - just an explaining comment:
# The Dummy class is responsible for ...
class Dummy
# Do things...
end
Prefer single-quoted strings when you don't need string interpolation or special symbols. Open
session["devise.user_attributes"] = user.attributes
- Read upRead up
- Exclude checks
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"
"Every string in #{project} uses double_quotes"
Extra empty line detected at class body beginning. Open
def all
- Read upRead up
- Exclude checks
This cops checks if empty lines around the bodies of classes match the configuration.
Example: EnforcedStyle: empty_lines
# good
class Foo
def bar
# ...
end
end
Example: EnforcedStyle: emptylinesexcept_namespace
# good
class Foo
class Bar
# ...
end
end
Example: EnforcedStyle: emptylinesspecial
# good
class Foo
def bar; end
end
Example: EnforcedStyle: noemptylines (default)
# good
class Foo
def bar
# ...
end
end
Missing top-level class documentation comment. Open
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
- 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

alias :bar :foo
