About

The reference printer for TypeLang. It renders TypeLang\Type\* AST nodes back into their string representation.

Two printers are provided:

• NativeTypePrinter — outputs a valid, native PHP type declaration.
• PrettyTypePrinter — outputs the full PHPStan/Psalm-style type, formatted across multiple lines.

Full documentation is available at typelang.dev.

Installation

Install the package via Composer:

composer require type-lang/printer

Requirements:

• PHP 8.4+

Usage

Parse a type into an AST (using type-lang/parser), then print it back with either printer:

$parser = newTypeLang\Parser\TypeParser();
$type = $parser->parse(<<<'PHP' array{ field1: (callable(Example, int): mixed), field2: list<Some>, ... }
PHP);
echonewTypeLang\Printer\NativeTypePrinter()->print($type);
// arrayechonewTypeLang\Printer\PrettyTypePrinter()->print($type);
// array{// field1: callable(Example, int): mixed,// field2: list<Some>,// ...// }
