Environment

Phalcon\Cli\Environment

This component provides functionality that helps writing CLI oriented code that has runtime-specific execution params.

How to use it?

Environment provides some useful methods:

• Environment::isWindows - Checks if currently running under MS Windows
• Environment::isAnsicon - When currently running under MS Windows checks if ANSI x3.64 is supported and enabled
• Environment::isConsole - Checks if running in a console environment (CLI)
• Environment::isInteractive - Checks if the file descriptor is an interactive terminal
• Environment::hasColorSupport - Checks the supports of colorization
• Environment::getDimensions - Gets the terminal dimensions based on the current environment
• Environment::setDimensions - Sets terminal dimensions
• Environment::getModeCon - Runs and parses Microsoft DOS MODE CON command if it's available (suppressing any error output)
• Environment::getSttySize - Runs and parses stty size command if it's available (suppressing any error output)
• Environment::getNumberOfColumns - Gets the number of columns of the terminal
• Environment::getNumberOfRows - Gets the number of rows of the terminal

Integration

Firstly you need to create an environment aware Console Application and implement Phalcon\Cli\Environment\EnvironmentAwareInterface:

namespace MyAwesomeApplication;

use Phalcon\Cli\Environment\EnvironmentInterface;
use Phalcon\Cli\Environment\EnvironmentAwareInterface;
use Phalcon\Di\FactoryDefault\Cli as CliDi;
use Phalcon\Cli\Console as PhConsole;
use Phalcon\DiInterface;

class Console extends PhConsole implements EnvironmentAwareInterface
{
    /**
     * @var EnvironmentInterface|null
     */
    protected $environment;

    public function __construct(DiInterface $di = null)
    {
        $di = $di ?: new CliDi;
        
        parent::__construct($di);
    }
    
    public function setEnvironment(EnvironmentInterface $environment)
    {
        $this->environment = $environment;
        
        return $this;
    }
    
    public function getEnvironment()
    {
        return $this->environment;
    }
}

Then you need to add Environment component to your Console Application.

use Phalcon\Cli\Environment\Environment;
use MyAwesomeApplication\Console;

$application = new Console;

$application->setEnvironment(
    new Environment
);

Implementing your own Environment

The Phalcon\Cli\Environment\EnvironmentInterface interface must be implemented to create your own Environment replacing the one provided by Phalcon\Cli\Environment component or extend the current one.
