Now the lexer is injected only once when creating the parser. Instead of
$parser = new PHPParser_Parser;
$parser->parse(new PHPParser_Lexer($code));
$parser->parse(new PHPParser_Lexer($code2));
you write:
$parser = new PHPParser_Parser(new PHPParser_Lexer);
$parser->parse($code);
$parser->parse($code2);
The template loaders loads templates from a base directory (and can
optionally use a suffix). For example
$templateLoader = new PHPParser_TemplateLoader(
$parser, './templates', '.php'
);
// loads ./templates/TestTemplate.php
$templateLoader->load('TestTemplate');
Again the implementation is not optimal. The loader probably shouldn't
intantiate the Template itself, but instead should accept a
TemplateFactory. This seemed like overkill to me, so I left it out.
