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:

Usage

Simple Example

Here's a basic example that filters only files:

Advanced Example

Filter files with advanced conditions:

Using Grouping and Logical Operators

You can group conditions to create complex expressions:

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):

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

Example: Using FilterBuilder via the Facade

Example: Using a Callable Predicate

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.

• basenameNotEquals($basenames): Excludes files with exact matching basenames.
• basenameContains($substrings): Matches basenames containing any of the substrings.
• basenameNotContains($substrings): Excludes basenames containing any of the substrings.
• basenameStartsWith($prefixes): Matches basenames that start with the given prefix(es).
• basenameEndsWith($suffixes): Matches basenames that end with the given suffix(es).

Extension-Based Conditions

• extensionEquals($extensions): Matches files with one or more exact extensions.
• extensionNotEquals($extensions): Excludes files with the specified extensions.
• extensionContains($substrings): Matches files whose extension contains any given substring.
• extensionNotContains($substrings): Excludes files whose extension contains any given substring.

Size-Based Conditions

• sizeEquals($size): Matches files with an exact size.
• sizeGt($size): Matches files larger than a specific size.
• sizeGte($size): Matches files larger than or equal to a specific size.
• sizeLt($size): Matches files smaller than a specific size.
• sizeLte($size): Matches files smaller than or equal to a specific size.
• sizeBetween($min, $max): Matches files within a size range.

📌 Note: Size units can be specified as B, K, M, G, T (e.g., '512K', '1G').

Date-Based Conditions

• lastModifiedBefore($timestamp): Matches files modified before a given timestamp or Carbon instance.
• lastModifiedAfter($timestamp): Matches files modified after a given timestamp or Carbon instance.

• depthGt($depth): Matches items with a depth greater than the specified value.
• depthLt($depth): Matches items with a depth less than the specified value.

Logical Operators
