YASC

Yet Another Sinatra Clone

yasc is a sinatra (kind of) clone written in php and highly influenced by zend framework 1.x, the routing system is based on limonade's code, is a tiny framework that uses user defined functions as actions (like in the MVC pattern) and annotations to route the requested url to a function.

Features

Functions based.
RESTful.
Tiny ^_^.
Routing system based on regex patterns, named params, pairs param (like zend framework 1.x).
View helpers.
Function helpers.
Layouts support.
Class autoloading based on the Framework Interop Group.
Models support.

Default project structure

yasc uses this project structure:

app.php
views/
    helpers/
models/

If you create these folders in your project they are auto-loaded in your application. Default namespaces:

helpers/Helper_*
models/Model_*

Accessors

I saw that invoking the requested function with a lot of arguments is too ugly and a little bit verbose (just a little?), so I add some accessors to be used in each function.

<?php

Yasc_App::view() // Access the view object inside your function.
Yasc_App::params() // Get all route params.
Yasc_App::params("key") // Get param "key" value, also, you can specify a default value as the second argument of this static method.
Yasc_App::config() // App config.
Yasc_App::viewHelper("url") // Get a view helper, like Layout, Url, or some of your own.
Yasc_App::functionHelper("flash") // Get a function helper, like Flash, this helper is a stack of messages, errors, notices, etc.

Prerequisites

yasc requires PHP 5.2.4 or later.

Installation

Easiest way to install yasc is through composer,

php composer.phar require nebiros/yasc "~0.1.18"

or add it as a git submodule.

Create a index.php or a app.php file and include yasc, like:

namespace My\App;

// composer autoload.
require_once "vendor/autoload.php";
// yasc runtime.
require_once "vendor/nebiros/yasc/src/Yasc.php";

$yasc = new \Yasc();
$yasc->run(__NAMESPACE__);
unset($yasc);

Add a function and a pattern using an annotation for your application index, your script will be something like this:

<?php
namespace My\App;

// composer autoload.
require_once "vendor/autoload.php";
// yasc runtime.
require_once "vendor/nebiros/yasc/src/Yasc.php";

$yasc = new \Yasc();
$yasc->run(__NAMESPACE__);
unset($yasc);

/**
 * @GET("/")
 */
function index() {
    echo "Hello world!";
}

Now, go to your favorite browser and run your script:

http://localhost/app.php

Follow the examples and you'r done :).

Setup

Maybe you want to hide your script file from the URL, http://app.com/app.php/some/thing (I know, pretty URLs, SEO shut, blah, blah) and get something fancier like: http://app.com/some/thing, ok, well, create a VirtualHost and add a .htaccess file to your application folder like this:

Virtual host configuration

<VirtualHost *:80>
   DocumentRoot "/path/to/your/application/public"
   ServerName app.com
   <Directory "/path/to/your/application/public">
       Options -Indexes MultiViews FollowSymLinks
       AllowOverride All 
       Order allow,deny
       Allow from all 
   </Directory>
</VirtualHost>

.htaccess file

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

NOTE: Your app file must be named index.php in order to work with this .htaccess file.

Simple Example

<?php
namespace My\App;

// composer autoload.
require_once "vendor/autoload.php";
// yasc runtime.
require_once "vendor/nebiros/yasc/src/Yasc.php";

$yasc = new \Yasc();
$yasc->run(__NAMESPACE__);
unset($yasc);

/**
 * @GET("/")
 */
function index() {
    echo "Hello world!";
}

/**
 * @POST("/")
 */
function create() {
    // save something.
}

/**
 * @PUT("/")
 */
function update() {
    // update something.
}

/**
 * @DELETE("/")
 */
function destroy() {
    // delete something.
}

Configuration

<?php

/**
 * Function to configure some yasc options. This function is optional you don't
 * need to write it in your app script if you don't want.
 */
function configure() {
    // * You can add a layout, a layout is just a .phtml file that represents
    // the site template.
    Yasc_App::config()->setLayoutScript(dirname(__FILE__) . "/layouts/default.phtml");
    
    // * If you want to use a stream wrapper to convert markup of mostly-PHP 
    // templates into PHP prior to include(), seems like is a little bit slow,
    // so by default is off.
    // ->setViewStream(true);
    // 
    // * You can add more than one folder to store views, each view script
    // is a .phtml file.
    // ->addViewsPath(dirname(__FILE__) . "/extra_views");
    // 
    // * You can add more than one path of view helpers and set a
    // class prefix for the path added.
    // ->addViewHelpersPath(dirname(__FILE__) . "/../library/My/View/Helper", "My_View_Helper");
    // 
    // or if you don't want a class prefix just leave it blank.
    // ->addViewHelpersPath(dirname(__FILE__) . "/extra_views/helpers");
    //
    // * Function helpers, second argument is a prefix class.
    // ->addFunctionHelpersPath(dirname(__FILE__) . "/extra_function_helpers");
    // 
    // * Add models folder, second argument is a prefix class.
    // ->addModelsPath(dirname(__FILE__) . "/models");
    // ->addModelsPath(dirname(__FILE__) . "/extra_models/My/Model", "My_Model");
    // 
    // * Add extra options to the configuration object, like some $mysql connection 
    // resource or a global flag, etc.
    // ->addOption("db", $mysql);
}

Pre- and Post-Dispatch Hooks

We provide two functions, pre_dispatch and post_dispatch, that may be called before and after an action is invoked.

Advanced Examples

<?php

/**
 * @GET("/")
 */
function index() {
    // Use layout view helper to disable the layout or use Yasc_Layout object
    // Yasc_Layout::getInstance()->disable(), Yasc_Layout uses singleton pattern.    
    Yasc_App::view()->layout()->disable();
    
    // Get the mysql resource from this app configuration option.
    // 
    // $mysql = Yasc_App::config()->getOption("db");
    // 
    // ... do some sql operation.
    
    echo "Hello world!";
}

 * @POST("/")
 * 
 * You can route the same url to another function using a different request
 * method.
