This is an optional template to run the drwcli framework

drwcli

Drwcli is a dependency-free toolkit for building CLI-only applications in PHP created by @walegbenga. This repository is a template you can use to create a new application that has a single dependency: drwcli/drwcli.

Why drwcli

The current trend in software development is basing your project on a big pile of unknowns. There is nothing wrong in using third party software, but if more than 80% of your application is out of your control, things can get messy. What usually happens is that you don't even know what packages you're depending on, when using the most popular frameworks.

It can be used for microservices, personal dev tools, bots and little fun things.

Getting Started

You'll need php-cli and Composer to get started.

Create a new project with:

composer create-project --prefer-dist drwcli/application myapp

Once the installation is finished, you can run drwcli it with:

cd myapp
./drwcli

This will show you the default app signature:

usage: ./drwcli help

The default help command that comes with drwcli (app/Command/Help/DefaultController.php) auto-generates a tree of available commands:

./drwcli help

Available Commands

help
└──test

The help test command, defined in app/Command/Help/TestController.php, shows an echo test of parameters:

./minicli help test user=gbenga name=value

Hello, gbenga!

Array
(
    [user] => gbenga
    [name] => value
)

The simplest app

The simplest drwcli script doesn't require using Command Controllers at all. You can delete the app folder and use registerCommand with an anonymous function, like this:

#!/usr/bin/php
<?php

if (php_sapi_name() !== 'cli') {
    exit;
}

require __DIR__ . '/vendor/autoload.php';

use \Drwcli\App;
use \Drwcli\Command\CommandCall;

$app = new App();
$app->setSignature('./drwcli mycommand');

$app->registerCommand('mycommand', function(CommandCall $input) {
    echo "My Command!";

    var_dump($input);
});

$app->runCommand($argv);
