Flysystem Filter

Flysystem Filter is a lightweight and intuitive filtering layer for League/Flysystem. It provides an easy-to-use FilterBuilder for logical and chainable filtering of filesystem contents (DirectoryListing).

Features

• Simple Filtering: Filter filesystem contents without writing complex callback functions.
• Logical Expressions: Combine conditions using and(), or(), group_start(), and group_end().
• Chainable API: Build complex filters with a readable, chainable syntax.
• Integration with Flysystem: Works seamlessly with League/Flysystem's DirectoryListing.

Installation

Install via Composer:

composer require marktaborosi/flysystem-filter

Usage

Simple Example

Here's a basic example that filters only files:

use League\Flysystem\Filesystem;
use League\Flysystem\Local\LocalFilesystemAdapter;
use Marktaborosi\FlysystemFilter\FilterBuilder;
use Marktaborosi\FlysystemFilter\FlysystemFilter;

require 'vendor/autoload.php';

$adapter = new LocalFilesystemAdapter(__DIR__ . '/tests/Storage/');
$flysystem = new Filesystem($adapter);
$flysystemContents = $flysystem->listContents('', true);

$filter = new FilterBuilder();
$filter->isFile();

$flysystemFilter = new FlysystemFilter();
$filteredResults = $flysystemFilter->filter($flysystemContents, $filter);

foreach ($filteredResults as $result) {
    echo $result->path() . PHP_EOL;
}

Advanced Example

Filter files with advanced conditions:

$filter = new FilterBuilder();
$filter
    ->extensionEquals(['txt', 'log'])
    ->and()
    ->isPublic()
    ->and()
    ->sizeLt('1G');

$flysytemFilter = new FlysystemFilter();
$filteredResults = $flysystemFilter->filter($flysystemContents, $filter);

Using Grouping and Logical Operators

You can group conditions to create complex expressions:

$filter = new FilterBuilder();
$filter
    ->group_start()
        ->extensionContains(['log', 'txt'])
        ->and()
        ->isFile()
    ->group_end()
    ->or()
    ->pathMatchesRegex('/debug/');

$flysytemFilter = new FlysystemFilter();
$filteredResults = $flysystemFilter->filter($flysystemContents, $filter);

Laravel Integration

From v3.0.0, Flysystem Filter ships with native Laravel support — including a Service Provider and a Facade — for seamless integration into your Laravel projects.

Installation

If installed via Composer in a Laravel application, the package will be automatically discovered thanks to Laravel's package auto-discovery.

composer.json (auto-discovery config — already included in this package):

{
  "extra": {
    "laravel": {
      "providers": [
        "Marktaborosi\\FlysystemFilter\\Laravel\\FlysystemFilterServiceProvider"
      ],
      "aliases": {
        "FlysystemFilter": "Marktaborosi\\FlysystemFilter\\Laravel\\FlysystemFilterFacade"
      }
    }
  }
}

If you have disabled auto-discovery, register them manually in config/app.php:

'providers' => [
    Marktaborosi\FlysystemFilter\Laravel\FlysystemFilterServiceProvider::class,
],
'aliases' => [
    'FlysystemFilter' => Marktaborosi\FlysystemFilter\Laravel\FlysystemFilterFacade::class,
],

Example: Using FilterBuilder via the Facade

use Illuminate\Support\Facades\Storage;
use Marktaborosi\FlysystemFilter\FilterBuilder;
use FlysystemFilter; // Facade alias

Route::get('/filtered-files', function () {
    $listing = Storage::disk('local')->listContents('', true);

    $builder = (new FilterBuilder())
        ->isFile()
        ->group_start()
            ->filenameContains('console')
            ->or()
            ->filenameContains('file')
        ->group_end();

    $filtered = FlysystemFilter::filter($listing, $builder);

    return $filtered->map(fn($i) => $i->path())->toArray();
});

Example: Using a Callable Predicate

use Illuminate\Support\Facades\Storage;
use League\Flysystem\StorageAttributes;
use FlysystemFilter;

Route::get('/log-files', function () {
    $listing = Storage::disk('local')->listContents('', true);

    // Callable allows custom filter logic without building a `FilterBuilder`
    $callable = static fn(StorageAttributes $item): bool =>
        str_ends_with($item->path(), '.log');

    $filtered = FlysystemFilter::filter($listing, $callable);

    return $filtered->map(fn($i) => $i->path())->toArray();
});

Notes

• FlysystemFilter::filter() is now an instance method (since v3.0.0) — the Facade makes it look static in Laravel, but under the hood it is resolved from the container.
• All filtering logic and method signatures remain the same as in standalone usage.
• Non-StorageAttributes entries in the listing are automatically skipped.
