Evaluator

Evaluates expressions and renders css values.

class MMO\client\scs\Evaluator

Espace de noms: MMO\client\scs
Voir: Compiler which owns the definitions this evaluator reads.

It is the single place where the three namespaces of the language are resolved: ```text $name compile-time variable, then theme token -> var(--name) name(...) @fn, built-in, or plain css function php::name(...) explicitly authorized php callable context::name value injected by the php application ```

retourne	Value

render($node, $scope, $selector, $quote)

Evaluator.php:69

Render a css value, a selector or an at-rule prelude, keeping the source's own spacing.

function render( MMO\client\scs\nodes\ValueListNode $node, MMO\client\scs\Scope $scope, ?string $selector = null, bool $quote = true ): string

$node	ValueListNode
$scope	Scope
$selector = null	null \| string
$quote = true	bool	false to drop string quotes (selector and interpolation context)
retourne	string

string($node, $scope, $selector)

Evaluator.php:52

Build a string whose ${...} parts are evaluated.

unitOf($operator, $left, $right, $node)

Evaluator.php:289

The unit of an arithmetic result. Incompatible units are a compile error (the spec, 5.4).

$operator	string
$left	Value
$right	Value
$node	Node
retourne	string

valueOf($node, $scope, $selector)

Evaluator.php:85

Evaluate a value list as a single value: a lone term keeps its type (a map stays a map, a number stays a number), a comma separated list becomes a list, anything else becomes the css text it renders to.

function valueOf( MMO\client\scs\nodes\ValueListNode $node, MMO\client\scs\Scope $scope, ?string $selector = null ): MMO\client\scs\Value

$node	ValueListNode
$scope	Scope
$selector = null	null \| string
retourne	Value

variable($node, $scope)

Evaluator.php:116

Resolve $name / $name.path: a compile-time variable first, a theme token second.

protected function variable(MMO\client\scs\nodes\VariableRefNode $node, MMO\client\scs\Scope $scope): MMO\client\scs\Value

Voir: the spec, 38 and 39 -- a theme token never becomes its value, it becomes var(--name-path).
