Converts native PHP types exposed by Reflection objects into TypeLang
TypeLang\Type\* AST nodes.
Given a ReflectionClassConstant, ReflectionProperty, ReflectionParameter
or ReflectionFunctionAbstract, it returns the matching type node (or null
when no type is declared).
Full documentation is available at typelang.dev.
Install the package via Composer:
composer require type-lang/reader
Requirements:
- PHP 8.1+
TypeLang\Reader\ReflectionReader exposes a find*Type() method for every kind
of Reflection object:
$reader = new TypeLang\Reader\ReflectionReader(); $node = $reader->findFunctionType( new ReflectionFunction(function (): void {}), ); var_dump($node); // object(TypeLang\Type\NamedTypeNode) { // ["name"] => "void" // ... // }
Combine it with type-lang/printer
to dump the resolved types of a whole class:
$class = new ReflectionClass(Path\To\Example::class); $reader = new TypeLang\Reader\ReflectionReader(); $printer = new TypeLang\Printer\PrettyTypePrinter(); foreach ($class->getProperties() as $property) { if ($type = $reader->findPropertyType($property)) { echo "property {$property->name}: {$printer->print($type)}\n"; } } foreach ($class->getMethods() as $method) { if ($type = $reader->findFunctionType($method)) { echo "method {$method->name}(): {$printer->print($type)}\n"; } }
Constants (findConstantType()) and parameters (findParameterType()) are read
the same way.
