PicowaCore is a Sinatra-like tiny web application framework for PHP 5.2 that was 
derived from Fitzgerald framework and anatoo's Curry, Quotation library and 
inspired by Blanka framework.

Fitzgerald framework:

Blanka framework:

anatoo's Curry and Quotation library:

Example 1 : minimum applicaton

	$app = new Picowa;
	
	$app->get('/','hello');
		function hello() {
			return 'Hello world!';
		}
	
	$app->run();


Exapmle 2 : more object oriented

	class Application extends Picowa {
		public function hello() {
			return 'Hello world!';
		}
	}

	$app = new Application;
	$app->get('/', $app->_hello());
	$app->run();


Exapmle 3 : argument passing

	$app = new Picowa;
	
	$app->get('/:page', bind('get_page',$app), array('page'=>'about|contact|faq'));
		function get_page($app, $page) {
			return $app->render($page);
		}
	
	$app->run();


Exapmle 4 : before filter

	class Application extends Picowa {
		public function hello($name) {
			return "Hello {$name}!";
		}
		
		public function debuglog($args) {
			var_dump($args);
		}
	}
	
	$app = new Application;
	$app->get('/:name', $app->_hello(), array('name'=>'Jon|Ponch'));
	$app->before('get','/:name', $app->_debuglog());
	
	$app->run();


Exapmle 5 : after filter

	$app = new Picowa;
	
	$app->get('/','hello');
	$app->get('/ja/','hello');
		function hello() {
			return 'Hello world!';
		}
	
	$app->after('get','/ja/','translate');
		function translate($text) {
			return strtr($text, array('Hello'=>'こんにちは','world'=>'世界'));
		}
	
	$app->run();


Exapmle 6 : before/around/after filter and execution order

	$app = new Picowa;
	
	$app->get('/','hello');
		function hello() {
			echo __FUNCTION__.',';
			return "Hello world!";
		}
	
	$app->before('GET','.*','before_1');
		function before_1($args) {
			echo __FUNCTION__.',';
		}

	$app->before('GET','.*','before_2');
		function before_2($args) {
			echo __FUNCTION__.',';
		}

	$app->after('GET','.*','after_1');
		function after_1($text) {
			echo __FUNCTION__.',';
			return $text;
		}

	$app->after('GET','.*','after_2');
		function after_2($text) {
			echo __FUNCTION__.',';
			return $text;
		}

	$app->around('GET','.*','around_1');
		function around_1($fn,$args) {
			echo __FUNCTION__.':start,';
			$text = apply($fn,$args);
			echo __FUNCTION__.':end,';
			return $text;
		}

	$app->around('GET','.*','around_2');
		function around_2($fn,$args) {
			echo __FUNCTION__.':start,';
			$text = apply($fn,$args);
			echo __FUNCTION__.':end,';
			return $text;
		}
	
	// before_1,before_2,around_1:start,around_2:start,
	// hello,
	// around_2:end,around_1:end,after_1,after_2,
	
	$app->run();
