ENV variables in Nette DI configuration (nette, php and parameters sections excluded).

Install

composer require rixxi/env:~1.0 or @dev if you are mad.

Put extension at least before other extensions that use ENV variables in configuration.

Configure

By default only defined parameters are registered. If you want all environment variables be available then turn whitelist: off..

Example of kdyby/doctrine configuration

env:
	parameters:
		DB_HOST: 127.0.0.1
		DB_NAME:
		DB_DRIVER: pgsql
		DB_USERNAME:
		DB_PASSWORD:

doctrine:
	host: %env.DB_HOST%
	dbname: %env.DB_NAME%
	driver: pdo_%env.DB_DRIVER%
	username: %env.DB_USERNAME%
	password: %env.DB_PASSWORD%
	// ... other stuff

extensions:
	env: Rixxi\Env\DI\EnvExtension

When running application at least DB_NAME ENV must be set. You can do that directly via shell

DB_NAME=test php www/index.php

or in config of apache or fpm pool.

Limitations

• Only other 3rd party extension configuration is supported that means no variables in nette or php.
• Sections parameters and services are not supported. It is not possible at this time due to limitations of nette/di.
• Only string names and scalar and null values are supported. This one is on purpose.
