This cop 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",

Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

Use the new Ruby 1.9 hash syntax. Open
render json: nil, :status => :unprocessable_entity
- Read upRead up
- Exclude checks
This cop checks hash literal syntax.
It can enforce either the use of the class hash rocket syntax or the use of the newer Ruby 1.9 syntax (when applicable).
A separate offense is registered for each problematic pair.
The supported styles are:
- ruby19 - forces use of the 1.9 syntax (e.g.
{a: 1}
) when hashes have all symbols for keys - hash_rockets - forces use of hash rockets for all hashes
- nomixedkeys - simply checks for hashes with mixed syntaxes
- ruby19nomixed_keys - forces use of ruby 1.9 syntax and forbids mixed syntax hashes
Example: EnforcedStyle: ruby19 (default)
# bad
{:a => 2}
{b: 1, :c => 2}
# good
{a: 2, b: 1}
{:c => 2, 'd' => 2} # acceptable since 'd' isn't a symbol
{d: 1, 'e' => 2} # technically not forbidden
Example: EnforcedStyle: hash_rockets
# bad
{a: 1, b: 2}
{c: 1, 'd' => 5}
# good
{:a => 1, :b => 2}
Example: EnforcedStyle: nomixedkeys
# bad
{:a => 1, b: 2}
{c: 1, 'd' => 2}
# good
{:a => 1, :b => 2}
{c: 1, d: 2}
Example: EnforcedStyle: ruby19nomixed_keys
# bad
{:a => 1, :b => 2}
{c: 2, 'd' => 3} # should just use hash rockets
# good
{a: 1, b: 2}
{:c => 3, 'd' => 4}
