The Parser Component

Feature Toggling

You can enable or disable a set of parser features if your task requires only partial support of the functionality. Such a feature allows you to conveniently implement more strict functionality.

$parser = new TypeLang\Parser\Parser(
    literals: false,
);

$result = $parser->parse('42');

// Uncaught TypeLang\Parser\Exception\ParseException:
//   Literal values not allowed in "42" at column 1
