CLI library of the PHP Ride framework.

Command

The Command interface is what you will implement to extend the CLI. It contains the logic for your action.

You can check this code sample of a command:

<?php

use ride\library\cli\command\AbstractCommand;

class MyCommand extends AbstractCommand {

    public function __construct() {
        parent::__construct('name', 'description');
        
        // Define a required argument
        $this->addArgument('arg1', 'description');
        
        // Define a optional argument
        $this->addArgument('arg2', 'description', false);

        // Define a dynamic argument
        // The value is the rest of the command line.
        // There are no more arguments allowed after a dynamic one
        $this->addArgument('arg3', 'description', false, true);
        
        // Define a flag (always optional)
        $this->addFlag('flag', 'description');
    }
    
    public function execute() {
        // Get the defined input values
        $arg1 = $this->input->getArgument('arg1');
        $arg2 = $this->input->getArgument('arg2', 'default');
        $arg3 = $this->input->getArgument('arg3');
        $flag = $this->input->getFlag('flag');

        if ($this->input->isInteractive()) {
            // Interactive shell, read some input interactive
            $arg4 = $this->input->read($this->output, 'my prompt: ');
        }            
        
        // Write some output
        $this->output->write("output");
        $this->output->writeLine("output line");
        $this->output->writeError("error output");
        $this->output->writeErrorLine("error output line");
    }
    
}

Code Sample

Check this code sample to create a CLI from this library:

<?php

use ride\library\cli\command\CommandContainer;
use ride\library\cli\input\PhpInput;
use ride\library\cli\output\PhpOutput;
use ride\library\cli\Cli;
use ride\library\cli\CommandInterpreter;

// Create a command container and add some commands to it
$commandContainer = new CommandContainer();
$commandContainer->addCommand(new MyCommand()); // the command from previous sample

// Create a command interpreter from the container
$commandInterpreter = new CommandInterpreter($commandContainer);

// Create your input and output interface
$input = new PhpInput(); // ReadlineInput for interactive shell with auto completion and history 
$output = new PhpOutput();

// and create and run the cli
$cli = new Cli($commandInterpreter);
$cli->setInput($input); // input for the commands
$cli->setOutput($output);

$cli->run($input); // input for the CLI, you can use ArgumentInput to parse the command line

// exit with a proper code
exit($cli->getExitCode());
