PHP Console Kit

PHP Console Kit is a simple PHP library for creating command-line applications. Library strongly inspired by Laravel Artisan Console. This project is based on rakit/console.

Features

• Closure command. You don't need to create class for simple command.
• Built-in command list.
• Auto help handler for each commands.
• Easy command signature.
• Aligned multiline command descriptions.
• Long options with hyphenated names.
• Password input.
• Simple Coloring.

Installation

Install the package:

composer require michalskoula/console

Quickstart

1. Create App

Create a file named cli (without extension).

<?php

use MichalSkoula\Console\App;

require('vendor/autoload.php');

// 1. Initialize app
$app = new App;

// 2. Register commands
$app->command('hello {name}', 'Say hello to someone', function($name) {
    $this->writeln("Hello {$name}");
});

// 3. Run app
$app->run();

2. Running Command

Open terminal/cmd, go to your app directory, run this command:

php cli hello "John Doe"

3. Command List

You can see available commands by typing this:

php cli list

4. Show Help

You can show help by putting --help or -h for each command. For example:

php cli hello --help

Command groups and colors

Use groups to organize the command list. Commands are displayed in registration order.

use MichalSkoula\Console\Color;

$app->group('Maintenance', Color::RED, function () {
    $this->command('maintenance:on', 'Enable maintenance mode', function () {
        // ...
    });
});

The fourth argument of command() changes the command name color:

$app->command('danger', 'Run a dangerous command', function () {
    // ...
}, Color::RED);

Available foreground colors are defined as Color constants, for example Color::LIGHT_GREEN and Color::YELLOW.

Multiline descriptions

Command descriptions may contain multiple lines. Continuation lines are automatically aligned in both the command list and --help output.

$app->command(
    'export',
    implode(PHP_EOL, [
        'Export records',
        'recent              Recent records only',
        'all                 All records',
    ]),
    function () {
        // ...
    }
);

The command list renders the continuation lines below the first description line:

1/ export   Export records
            recent              Recent records only
            all                 All records

Long option names

Long option names may contain hyphens and are included in help and shell autocomplete:

$app->command(
    'export {--dry-run::Preview without saving} {--include-archived::Include archived records}',
    'Export records',
    function () {
        if ($this->option('dry-run')) {
            // ...
        }
    }
);

Running php cli export --help includes the declared long options:

Options:
  --dry-run           Preview without saving
  --include-archived  Include archived records

The complete help screen stays aligned even when short aliases and long option names are mixed:

List header

Use setListHeader() to replace the default Available Commands: text. The header supports multiple lines, including ASCII art.

$app->setListHeader(<<<'HEADER'
My Console
==========
HEADER, Color::CYAN);

Pass a third argument in milliseconds to display the header with a typing effect:

$app->setListHeader($asciiArt, Color::CYAN, 12);

Shell autocomplete

Enable Bash autocomplete with a generated script.

source <(./cli completion bash)

To enable it permanently, generate the script once and load it from ~/.bashrc:

./cli completion bash > ~/.cli-completion.bash
echo 'source ~/.cli-completion.bash' >> ~/.bashrc
source ~/.bashrc

Command names and options are detected automatically. For positional arguments, whose possible values cannot be inferred from the command signature, declare the allowed values explicitly:

$app->command('deploy {environment}', 'Deploy the application', function (string $environment) {
    // ...
});

$app->setCompletionValues('deploy', 'environment', ['staging', 'production']);

Development

Install development dependencies and run the complete quality suite:

composer install
composer check

The checks can also be run separately. The default commands only report changes:

composer test
composer ecs
composer rector

Apply automatic formatting and refactoring explicitly:

composer ecs:fix
composer rector:fix
