README

A message stack system that accumulates messages while continuing process.

Features

• Stack messages with different severity levels (ERROR, WARNING, INFO, SUCCESS)
• Continue processing even after errors (configurable)
• Multi-language support via YAML message definitions
• Type-safe implementation using PHP 8.1 enums
• Simple and intuitive API

Installation

composer require denshoch/msg-stack

Basic Usage

use Denshoch\MsgStack\MessageStore;
use Denshoch\MsgStack\MessageType;

// Initialize with message directory and language
$messageStore = new MessageStore(__DIR__ . '/messages', 'ja');

// Configure error handling
$messageStore->setContinueOnError(true);

try {
    // Add messages of different types
    $messageStore->addMessage(
        MessageType::WARNING,
        'W001',
        ['filename' => 'example.jpg']
    );

    // Process continues...
    $messageStore->addMessage(
        MessageType::ERROR,
        'E001',
        ['path' => '/invalid/path']
    );

} catch (MessageException $e) {
    // Handle errors when continueOnError is false
} finally {
    // Get all accumulated messages
    $allMessages = $messageStore->getMessages();
    
    // Or get messages by type
    $warnings = $messageStore->getMessages(MessageType::WARNING);
    
    // Check for specific message types
    if ($messageStore->hasMessages(MessageType::ERROR)) {
        // Handle errors...
    }
}

Message Definition

Create YAML files in your messages directory:

# messages/en.yml
W001: 'Low resolution image detected: {filename}'
E001: 'Invalid path: {path}'

# messages/ja.yml
W001: '低解像度の画像が検出されました: {filename}'
E001: '不正なパスです: {path}'
