README

This library is an implementation of the php-extended/php-parser-interface based on a lexer for handling its data.

Basic Usage

This library provide a single class, the AbstractParserLexer which is made to be implemented. Its parseLexer method must return a single object from the whole string that its given, and throw a ParseException if it is impossible to do so.

It is advised that the parseLexer method use a combination of :

public function parseLexer(LexerInterface $lexer)
{
	$lexer->rewind(); // do not forget !
	$token = $this->expectOneOf($lexer, [<tokenids>]);
	$this->expectEof($lexer, $token);
	
	return MyObject($token->getData());
}

As the LexerInterface is an \Iterable, you may as well use it into a foreach loop.
