A flexible Laravel package for generating filenames using various strategies and options.

• ✅ Flexible Filename Generation – Generate filenames dynamically using various strategies.
• 🎲 Multiple Strategies – Supports random, uuid, timestamp, date, numbered, slug, and hash.
• 🔧 Customizable Output – Specify filename, extension, and additional formatting options.
• 🎯 Laravel-Friendly – Designed to work seamlessly with Laravel's filesystem and configuration.
• 📂 Human-Readable & Unique Names – Ensures filenames are structured, collision-free, and easy to understand.
• ⚙️ Configurable Defaults – Define global settings in config/onym.php for consistency across your application.
• 🔌 Extensible & Developer-Friendly – Easily add custom filename strategies or modify existing ones.

You can install the package via composer:

composer require blaspsoft/onym

You can publish the config file with:

php artisan vendor:publish --tag="onym-config"

Generates a random string of characters for the filename.

Options:

• length (int): The length of the random string
  • Default: 16
  • Example: ['length' => 8] generates "a1b2c3d4.txt"
• prefix (string): String to prepend to the filename
  • Default: ''
  • Example: ['prefix' => 'temp_'] generates "temp_a1b2c3d4.txt"
• suffix (string): String to append before the extension
  • Default: ''
  • Example: ['suffix' => '_draft'] generates "a1b2c3d4_draft.txt"

use Blaspsoft\Onym\Facades\Onym;

// Generate an 8-character random filename with prefix and suffix
Onym::make(strategy: 'random', options: [
    'length' => 8,
    'prefix' => 'temp_',
    'suffix' => '_draft'
]);
// Result: "temp_a1b2c3d4_draft.txt"

// You can also use the random method directly
Onym::random(string $extension, ?array $options = [])

Generates a UUID v4 (universally unique identifier) for the filename.

Options:

• prefix (string): String to prepend to the filename
  • Default: ''
  • Example: ['prefix' => 'id_'] generates "id_123e4567-e89b-12d3-a456-426614174000.txt"
• suffix (string): String to append before the extension
  • Default: ''
  • Example: ['suffix' => '_backup'] generates "123e4567-e89b-12d3-a456-426614174000_backup.txt"

use Blaspsoft\Onym\Facades\Onym;

// Generate a UUID filename with prefix and suffix
Onym::make(strategy: 'uuid', options: [
    'prefix' => 'id_',
    'suffix' => '_backup'
]);
// Result: "id_123e4567-e89b-12d3-a456-426614174000_backup.txt"

// You can also use the uuid method directly
Onym::uuid(string $extension, ?array $options = [])

Adds a timestamp to the filename using PHP's DateTime formatting.

Options:

• format (string): PHP DateTime format string
  • Default: 'Y-m-d_H-i-s'
  • Common formats:
    • 'Y-m-d_H-i-s' → "2024-03-15_14-30-00"
    • 'YmdHis' → "20240315143000"
    • 'U' → Unix timestamp (e.g., "1710506400")
• prefix (string): String to prepend to the filename
  • Default: ''
  • Example: ['prefix' => 'log_']
• suffix (string): String to append before the extension
  • Default: ''
  • Example: ['suffix' => '_archive']

use Blaspsoft\Onym\Facades\Onym;

// Using timestamp with prefix and suffix
Onym::make('document', 'pdf', 'timestamp', [
    'format' => 'Y-m-d_H-i-s',
    'prefix' => 'log_',
    'suffix' => '_archive'
]);
// Result: "log_2024-03-15_14-30-00_document_archive.pdf"

// You can also use the timestamp method directly
Onym::timestamp(string $defaultFilename, string $extension, ?array $options = [])

Similar to timestamp but focused on date-only formats.

Options:

• format (string): PHP DateTime format string
  • Default: 'Y-m-d'
  • Common formats:
    • 'Y-m-d' → "2024-03-15"
    • 'Ymd' → "20240315"
    • 'Y/m/d' → "2024/03/15"
• prefix (string): String to prepend to the filename
  • Default: ''
  • Example: ['prefix' => 'dated_']
• suffix (string): String to append before the extension
  • Default: ''
  • Example: ['suffix' => '_version']

use Blaspsoft\Onym\Facades\Onym;

// Using date with prefix and suffix
Onym::make('document', 'pdf', 'date', [
    'format' => 'Y-m-d',
    'prefix' => 'dated_',
    'suffix' => '_version'
]);
// Result: "dated_2024-03-15_document_version.pdf"

// You can also use the date method directly
Onym::date(string $defaultFilename, string $extension, ?array $options = [])

Adds a number to the filename.

Options:

• number (int): The number to append to the filename
  • Default: 1
  • Example: ['number' => 5]
• prefix (string): String to prepend to the filename
  • Default: ''
  • Example: ['prefix' => 'rev_']

Onym::make('document', 'pdf', 'numbered', [
    'number' => 5,
    'prefix' => 'rev_',
    'suffix' => '_final'
]);

    'suffix' => '_draft'
]);
// Result: "post_my-document-name_draft.pdf"

Onym::hash(string $defaultFilename, string $extension, ?array $options = [])

You can set default values for all strategies in your config/onym.php file:

return [
    // Default filename when none is provided
    'default_filename' => 'file',

    // Default extension when none is provided
    'default_extension' => 'txt',

    // Default strategy when none is specified
    'strategy' => 'random',

    // Default options for all strategies
    'options' => [

        'random' => [
            'length' => 16,
            'prefix' => '',
            'suffix' => '',
        ],

        'timestamp' => [
            'format' => 'Y-m-d_H-i-s',
            'prefix' => '',
            'suffix' => '',
        ],

        'date' => [
            'format' => 'Y-m-d',
            'prefix' => '',
            'suffix' => '',
        ],

        'numbered' => [
            'number' => 1,
            'separator' => '_',
            'prefix' => '',
            'suffix' => '',
        ],

        'hash' => [
            'algorithm' => 'md5',
            'length' => 16,
            'prefix' => '',
            'suffix' => '',
        ],
    ],
];

These defaults can be overridden on a per-call basis using the options parameter in the make() and in all strategy methods.
