Introduction

Helpers for a composer package.

Requirements

• PHP 7.1 or higher.

Installation

Install Zerotoprod\PackageHelper via Composer:

composer require zero-to-prod/package-helper

This will add the package to your project’s dependencies and create an autoloader entry for it.

Documentation Publishing

You can publish this README to your local documentation directory.

This can be useful for providing documentation for AI agents.

This can be done using the included script:

# Publish to default location (./docs/zero-to-prod/package-helper/)
vendor/bin/zero-to-prod-package-helper

# Publish to custom directory
vendor/bin/zero-to-prod-package-helper /path/to/your/docs

Automatic Documentation Publishing

You can automatically publish documentation by adding the following to your composer.json:

{
  "scripts": {
    "post-install-cmd": [
      "zero-to-prod-package-helper"
    ],
    "post-update-cmd": [
      "zero-to-prod-package-helper"
    ]
  }
}

Usage

Publish files in your package directory (recursively) while rewriting namespaces.

use Zerotoprod\PackageHelper\PackageHelper;

PackageHelper::publish(
    $from,
    $to,
    PackageHelper::determineNamespace($psr_4, $to),
    static function (string $from, string $to) {
        echo "Copied: $from to $to" . PHP_EOL;
    }
);

Copy a single file and get the destination path:

use Zerotoprod\PackageHelper\PackageHelper;

$copied = PackageHelper::copy(__DIR__.'/stubs/example.txt');
echo $copied; // e.g., getcwd().'/example.txt'

// Or copy into a specific directory and observe the callback
$copied = PackageHelper::copy(
    __DIR__.'/stubs/example.txt',
    getcwd().'/output',
    static function (string $from, string $to) {
        echo "Copied $from -> $to" . PHP_EOL;
    }
);

Example

Integrate this into a composer package.

Update composer.json:

{
  "bin": [
    "bin/package-file"
  ]
}

Create a new file: bin/package-file

#!/usr/bin/env php
<?php

require getcwd() . '/vendor/autoload.php';

use Zerotoprod\PackageHelper\PackageHelper;

if ($argc !== 2) {
    die("Usage: <targetDir>\n");
}

$from = __DIR__ . '/../src';
if (!is_dir($from)) {
    throw new RuntimeException("Source directory '$from' not found.");
}

$composer_json_file_path = getcwd() . '/composer.json';
if (!is_file($composer_json_file_path)) {
    throw new RuntimeException("composer.json not found.");
}

$composer_json_data = json_decode(file_get_contents($composer_json_file_path), true);
$psr_4 = $composer_json_data['autoload']['psr-4'] ?? null;

if (!$psr_4) {
    throw new RuntimeException('PSR-4 autoload section missing in composer.json.');
}

$to = rtrim($argv[1], '/');
PackageHelper::publish(
    $from,
    $to,
    PackageHelper::determineNamespace($psr_4, $to),
    static function(string $from, string $to){
        echo "Copied: $from to $to" . PHP_EOL;
    }
);
