Common classes to help with creating an application using the Slim micro framework and Twig template engine.

System Requirements

PHP >= 7.2.0

Configuration

The library follows the Twelve-Factor App configuration principle of configuration via environment variables.

The following variables can be optionally provided:

LOG_CHANNEL = Logger name (default: app)
LOG_LEVEL = PSR-3 logging level (default: notice)
LOG_FILE = fopen()-compatible filename or stream URI (default: php://stderr)
CACHE_DIR = Directory to cache twig templates (default: data/cache)
SMTP_HOST = SMTP mail server (default: localhost)
TEMPLATE_DIR = Twig template directory (default: data/templates)
I18N_DIR = i18n data file directory (default: data/i18n)
DEFAULT_LANG = Default i18n lanaguage (default: en)

Apache

SetEnv LOG_LEVEL debug
SetEnv CACHE_DIR /var/cache/twig
SetEnv DEFAULT_LANG es

.env file

For environments where container based configuration isn't possible or desired, a .env file can be placed in the root of the project. This file will be parsed using PHP's parse_ini_file() function and the resulting settings will be injected into the application environment.

LOG_LEVEL=debug
CACHE_DIR=/var/cache/twig
DEFAULT_LANG=es

Working on the code

Code review process is done through Gerrit. To start hacking on the application refer to the Gerrit Tutorial.
