Checks if the length a module exceeds some maximum value. Comment lines can optionally be ignored. The maximum allowed length is configurable.
You can set literals you want to fold with CountAsOne
.
Available are: 'array', 'hash', and 'heredoc'. Each literal
will be counted as one line regardless of its actual size.
Example: CountAsOne: ['array', 'heredoc']
module M
ARRAY = [ # +1
1,
2
]
HASH = { # +3
key: 'value'
}
MSG = <<~HEREDOC # +1
Heredoc

Checks the length of lines in the source code.
The maximum length is configurable.
The tab size is configured in the IndentationWidth
of the Layout/IndentationStyle
cop.
It also ignores a shebang line by default.
This cop has some autocorrection capabilities. It can programmatically shorten certain long lines by inserting line breaks into expressions that can be safely split across lines. These include arrays, hashes, and method calls with argument lists.
If autocorrection is enabled, the following Layout cops are recommended to further format the broken lines. (Many of these are enabled by default.)
- ArgumentAlignment
- BlockAlignment
- BlockDelimiters
- BlockEndNewline
- ClosingParenthesisIndentation
- FirstArgumentIndentation
- FirstArrayElementIndentation
- FirstHashElementIndentation
- FirstParameterIndentation
- HashAlignment
- IndentationWidth
- MultilineArrayLineBreaks
- MultilineBlockLayout
- MultilineHashBraceLayout
- MultilineHashKeyLineBreaks
- MultilineMethodArgumentLineBreaks
- ParameterAlignment
Together, these cops will pretty print hashes, arrays, method calls, etc. For example, let's say the max columns is 25:
Example:
# bad
{foo: "0000000000", bar: "0000000000", baz: "0000000000"}
# good
{foo: "0000000000",
bar: "0000000000", baz: "0000000000"}
# good (with recommended cops enabled)
{
foo: "0000000000",
bar: "0000000000",
baz: "0000000000",
}
Missing top-level documentation comment for module CollectionMatricesHelper
. Open
module CollectionMatricesHelper
- Read upRead up
- Exclude checks
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, constant definitions or constant visibility declarations.
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
module Math
end
# good
# Description/Explanation of Person class
class Person
# ...
end
# allowed
# Class without body
class Person
end
# Namespace - A namespace can be a class or a module
# Containing a class
module Namespace
# Description/Explanation of Person class
class Person
# ...
end
end
# Containing constant visibility declaration
module Namespace
class Private
end
private_constant :Private
end
# Containing constant definition
module Namespace
Public = Class.new
end
# Macro calls
module Namespace
extend Foo
end
Example: AllowedConstants: ['ClassMethods']
# good
module A
module ClassMethods
# ...
