README

symfony/dotenv adapter to load env.yml file instead

the env file will be cached with the symfony filecache adaper (the modified time of the env.yml will be check every request, updates will immediately invalidate the cache)

the yaml syntax will be reformed to match the flat Environment structure. nested element keys will be concated via ' _ ' (underscore). (numeric lists are KEY_0, KEY_1)

for example:

Vendor:
  SSO:
    Secret: superSecret
    Provider: stuff
  Captcha:
    secret: otherSecret
    Domain: http://oldDomain
    
Vendor_Captcha:
  Domain: https://domain

will be result in system env:

Vendor_SSO_Secret = superSecret
Vendor_SSO_Provider = stuff
Vendor_Captcha_Secret = otherSecret
Vendor_Captcha_Domain = https://domain

Installation

composer: composer require brannow/envyml

Post Integration

Disclamer: all code shown is based on symfony 5.0 (other symfony versions may need updates to run)

it is required to remove the dotenv code snippets from the index.php and bin/console

// ...

// env.yml loader announcement, this will disable dotenv loader
$_SERVER['APP_RUNTIME'] = \Brannow\Component\Envyml\SymfonyRuntime::class;

// set the custom APP_RUNTIME before this line!
require_once dirname(__DIR__).'/vendor/autoload_runtime.php';

// ...

update the path to your env.yml location:

putenv(ENV_FILE_PATH, 'ABSOLUTE_PATH_HERE')

or change in the entrypoint scripts (index.php / console)

// env.yml loader announcement, this will disable dotenv loader
$_SERVER['APP_RUNTIME'] = \Brannow\Component\Envyml\SymfonyRuntime::class;
$_ENV['ENV_FILE_PATH'] ??= './env.yml';

// symfony default
require_once dirname(__DIR__).'/vendor/autoload_runtime.php';

Best Practice

next update index.php and bin/console
index.php:

<?php

use App\Kernel;

// env.yml loader announcement, this will disable dotenv loader
$_SERVER['APP_RUNTIME'] = \Brannow\Component\Envyml\SymfonyRuntime::class;

require_once dirname(__DIR__).'/vendor/autoload_runtime.php';

return function (array $context) {
    return new Kernel($context['APP_ENV'], (bool) $context['APP_DEBUG']);
};

bin/console:

#!/usr/bin/env php
<?php

use App\Kernel;
use Symfony\Bundle\FrameworkBundle\Console\Application;

if (!is_file(dirname(__DIR__).'/vendor/autoload_runtime.php')) {
    throw new LogicException('Symfony Runtime is missing. Try running "composer require symfony/runtime".');
}

// env.yml loader announcement, this will disable dotenv loader
$_SERVER['APP_RUNTIME'] = \Brannow\Component\Envyml\SymfonyRuntime::class;

require_once dirname(__DIR__).'/vendor/autoload_runtime.php';

return function (array $context) {
    $kernel = new Kernel($context['APP_ENV'], (bool) $context['APP_DEBUG']);

    return new Application($kernel);
};

simply add

$_SERVER['APP_RUNTIME'] = \Brannow\Component\Envyml\SymfonyRuntime::class;

before

require_once dirname(__DIR__).'/vendor/autoload_runtime.php';
