Slim Config - YAML

Parses YAML files and adds them into Slim's config singleton. Uses Symfony's YAML Component to parse files (http://github.com/symfony/Yaml). Allows other YAML files to be imported and parameters to be set and used.

Getting Started

Installation

Composer

Install composer in your project.

curl -s https://getcomposer.org/installer | php

Create a composer.json file in your project root:

{
	"require": {
		"techsterx/slim-config-yaml": "1.*"
	}
}

Install via composer:

php composer.phar install

Add this line to your application's index.php file:

<?php
require 'vendor/autoload.php';

Manual Install

Download and extract src/ directory into your project directory and require it in your application's index.php file.

<?php
require 'Slim\Slim.php';
require 'Yaml.php';

$app = new \Slim\Slim();

\BurningDiode\Slim\Config\Yaml::getInstance()->addFile('/path/to/some/file');

Methods

Slim Config - YAML uses a static method to get the currenct instance. If an instance doesn't exist, a new one will be created. Use the getInstance() method to get the current instance.

$slimYaml = \BurningDiode\Slim\Config\Yaml::getInstance();

_() is the shorthand equivalent of getInstance().

$slimYaml = \BurningDiode\Slim\Config\Yaml::_();

To add a single file, use the addFile() method.

\BurningDiode\Slim\Config\Yaml::getInstance()->addFile('/path/to/some/file.yaml');

You can also chain multiple addFile() methods togethor.

\BurningDiode\Slim\Config\Yaml::getInstance()
    ->addFile('/path/to/some/file.yaml')
    ->addFile('/path/to/another/file.yaml');

You can import a whole directory of YAML files.

\BurningDiode\Slim\Config\Yaml::getInstance()->addDirectory('/path/to/directory');

You can chain with the addDirectory() method as well.

\BurningDiode\Slim\Config\Yaml::getInstance()
    ->addDirectory('/path/to/directory')
    ->addFile('/path/to/some/file.yaml');

Specify some global parameters to be used by all YAML files processed.

\BurningDiode\Slim\Config\Yaml::_()
    ->addParameters(array('app.root' => dirname(__FILE__)))
    ->addDirectory('/path/to/config/directory')
    ->addFile('/path/to/file/outside/of/config/directory.yml');

Using Parameters

You can specify parameters in YAML files that will be replaced using keywords. Parameters are only available to the resource currently being processed.

config.yaml

parameters:
    key1: value1
    key2: value2
    
application:
    keya: %key1%
    keyb: %key2%

app.php

\BurningDiode\Slim\Config\Yaml::_()->addFile('config.yml');

$config = $app->config('application');

print_r($config);

Output:

Array
(
    [key1] => value1
    [key2] => value2
)

Importing Files

You can import other YAML files which can be useful to keep all your common parameters in one file and used in others.

parameters.yml

parameters:
    db_host:  localhost
    db_user:  username
    db_pass:  password
    db_dbase: database

database.yml

imports:
    - { resource: parameters.yml }
    
database:
    hostname: %db_host%
    username: %db_user%
    password: %db_pass%
    database: %db_dbase%

app.php

\BurningDiode\Slim\Config\Yaml::_()->addFile('database.yml');

$db_config = $app->config('database');

print_r($db_config);

Output:

Array
(
    [hostname] => localhost
    [username] => username
    [password] => password
    [database] => database
)
