type PrimaryOption = Array<Keyword | AtRule | Rule>;
type Keyword = "custom-properties" | "dollar-variables" | "at-variables" | "declarations" | "rules" | "at-rules" | "less-mixins";
type AtRule = {
type: 'at-rule';
name?: string;
parameter?: string | RegExp;
hasBlock?: boolean;
};
type Rule = {
type: 'rule';
selector?: string | RegExp;
name?: string;
};
Within an order array, you can include:
-
keywords:
custom-properties
— Custom properties (e. g.,--property: 10px;
)dollar-variables
— Dollar variables (e. g.,$variable
)at-variables
— At-variables (e. g.,@variable
available in Less syntax)declarations
— CSS declarations (e. g.,display: block
)rules
— Nested rules (e. g.,a { span {} }
)at-rules
— Nested at-rules (e. g.,div { @media () {} }
)less-mixins
— Mixins in Less syntax (e. g.,.mixin();
)
-
extended at-rule objects:
{ "type": "at-rule", "name": "include", "parameter": "hello", "hasBlock": true }
-
extended rule objects:
{ "type": "rule", "selector": "div", "name": "tag selector" }
By default, unlisted elements will be ignored. So if you specify an array and do not include declarations
, that means that all declarations can be included before or after any other element. This can be changed with the unspecified
option (see below).
Extended at-rule objects
Extended at-rule objects have different parameters and variations.
Object parameters:
type
: always"at-rule"
name
:string
. E. g.,name: "include"
for@include
parameter
:string | RegExp
. A string will be translated into a RegExp —new RegExp(yourString)
— so be sure to escape properly. E. g.,parameter: "icon"
for@include icon(20px);
hasBlock
:boolean
. E. g.,hasBlock: true
for@include icon { color: red; }
and not for@include icon;
Always specify name
if parameter
is specified.
Matches all at-rules:
{
"type": "at-rule"
}
Or keyword at-rules
.
Matches all at-rules, which have nested elements:
{
"type": "at-rule",
"hasBlock": true
}
Matches all at-rules with specific name:
{
"type": "at-rule",
"name": "media"
}
Matches all at-rules with specific name, which have nested elements:
{
"type": "at-rule",
"name": "media",
"hasBlock": true
}
Matches all at-rules with specific name and parameter:
{
"type": "at-rule",
"name": "include",
"parameter": "icon"
}
Matches all at-rules with specific name and parameter, which have nested elements:
{
"type": "at-rule",
"name": "include",
"parameter": "icon",
"hasBlock": true
}
Each described above variant has more priority than its previous variant. For example, { "type": "at-rule", "name": "media" }
will be applied to an element if both { "type": "at-rule", "name": "media" }
and { "type": "at-rule", "hasBlock": true }
can be applied to an element.
Extended rule objects
Object parameters:
type
: always"rule"
selector
:string | RegExp
. Selector pattern. A string will be translated into a RegExp —new RegExp(yourString)
— so be sure to escape properly. Examples:selector: /^&:[\w-]+$/
matches simple pseudo-classes. E. g.,&:hover
,&:first-child
. Doesn't match complex pseudo-classes, e. g.&:not(.is-visible)
.selector: /^&::[\w-]+$/
matches pseudo-elements. E. g.&::before
,&::placeholder
.
name
:string
. Selector name (optional). Will be used in error output to help identify extended rule object.
Matches all rules:
{
"type": "rule"
}
Or keyword rules
.
Matches all rules with selector matching pattern:
{
"type": "rule",
"selector": "div"
}
{
"type": "rule",
"selector": "/^&:\\w+$/"
}
Optional secondary options
type SecondaryOptions = {
unspecified?: "top" | "bottom" | "ignore";
};
unspecified
Value type: "top" | "bottom" | "ignore"
.
Default value: "ignore"
.
Default behavior is the same as "ignore"
: an unspecified element can appear before or after any other property.
With "top"
, unspecified elements are expected before any specified properties. With "bottom"
, unspecified properties are expected after any specified properties.
Autofixing caveats
Keyword less-mixins
aren't supported.
unspecified
secondary option is always set to bottom
.
