This cop checks whether the end keywords of method definitions are aligned properly.
Two modes are supported through the EnforcedStyleAlignWith configuration
parameter. If it's set to start_of_line
(which is the default), the
end
shall be aligned with the start of the line where the def
keyword is. If it's set to def
, the end
shall be aligned with the
def
keyword.
Example: EnforcedStyleAlignWith: startofline (default)
# bad
private def foo
end
# good
private def foo
end
Example: EnforcedStyleAlignWith: def
# bad
private def foo
end
# good

end

This cop checks whether the end keywords are aligned properly.
Three modes are supported through the EnforcedStyleAlignWith
configuration parameter:
If it's set to keyword
(which is the default), the end
shall be aligned with the start of the keyword (if, class, etc.).
If it's set to variable
the end
shall be aligned with the
left-hand-side of the variable assignment, if there is one.
If it's set to start_of_line
, the end
shall be aligned with the
start of the line where the matching keyword appears.
Example: EnforcedStyleAlignWith: keyword (default)
# bad
variable = if true
end
# good
variable = if true
end
Example: EnforcedStyleAlignWith: variable
# bad
variable = if true
end
# good
variable = if true
end
Example: EnforcedStyleAlignWith: startofline
# bad
variable = if true
end
# good
puts(if true

Require === and !== (eqeqeq)
It is considered good practice to use the type-safe equality operators ===
and !==
instead of their regular counterparts ==
and !=
.
The reason for this is that ==
and !=
do type coercion which follows the rather obscure Abstract Equality Comparison Algorithm.
For instance, the following statements are all considered true
:
[] == false
[] == ![]
3 == "03"
If one of those occurs in an innocent-looking statement such as a == b
the actual problem is very difficult to spot.
Rule Details
This rule is aimed at eliminating the type-unsafe equality operators.
Examples of incorrect code for this rule:
/*eslint eqeqeq: "error"*/
if (x == 42) { }
if ("" == text) { }
if (obj.getStuff() != undefined) { }
The --fix
option on the command line automatically fixes some problems reported by this rule. A problem is only fixed if one of the operands is a typeof
expression, or if both operands are literals with the same type.
Options
always
The "always"
option (default) enforces the use of ===
and !==
in every situation (except when you opt-in to more specific handling of null
[see below]).
Examples of incorrect code for the "always"
option:
/*eslint eqeqeq: ["error", "always"]*/
a == b
foo == true
bananas != 1
value == undefined
typeof foo == 'undefined'
'hello' != 'world'
0 == 0
true == true
foo == null
Examples of correct code for the "always"
option:
/*eslint eqeqeq: ["error", "always"]*/
a === b
foo === true
bananas !== 1
value === undefined
typeof foo === 'undefined'
'hello' !== 'world'
0 === 0
true === true
foo === null
This rule optionally takes a second argument, which should be an object with the following supported properties:
-
"null"
: Customize how this rule treatsnull
literals. Possible values:-
always
(default) - Always use === or !==. -
never
- Never use === or !== withnull
. -
ignore
- Do not apply this rule tonull
.
-
smart
The "smart"
option enforces the use of ===
and !==
except for these cases:
- Comparing two literal values
- Evaluating the value of
typeof
- Comparing against
null
Examples of incorrect code for the "smart"
option:
/*eslint eqeqeq: ["error", "smart"]*/
// comparing two variables requires ===
a == b
// only one side is a literal
foo == true
bananas != 1
// comparing to undefined requires ===
value == undefined
Examples of correct code for the "smart"
option:
/*eslint eqeqeq: ["error", "smart"]*/
typeof foo == 'undefined'
'hello' != 'world'
0 == 0
true == true
foo == null
allow-null
Deprecated: Instead of using this option use "always" and pass a "null" option property with value "ignore". This will tell eslint to always enforce strict equality except when comparing with the null
literal.

When Not To Use It
If you don't want to enforce a style for using equality operators, then it's safe to disable this rule. Source: http://eslint.org/docs/rules/
