Flysystem plugin to add file finding capabilities to the Filesystem entity

, _(*1)

FlyFinder

FlyFinder is a utility class for Flysystem that will enable you to find files based on certain criteria., _(*2)

FlyFinder can search for files that are hidden (either because they are hidden files themselves, or because they are inside a hidden directory), that have a certain extension, or that exist in a certain path., _(*3)

Flyfinder does not return directories themselves... only files., _(*4)

Installation

The easiest way to install this library is with Composer using the following command:, _(*5)

$ composer require phpdocumentor/flyfinder

Examples

Usage

In order to use the FlyFinder plugin you first need a Flyfinder filesystem with an adapter, for instance the local adapter., _(*7)

use League\Flysystem\Filesystem;
use League\Flysystem\Local\LocalFilesystemAdapter as LocalAdapter;
use Flyfinder\Finder;

$filesystem = new Filesystem(new LocalAdapter(__DIR__.'/path/to/files/'));

Now you can create the Finder instance:, _(*8)

$finder = new Finder($filesystem); 

FlyFinder will need specifications to know what to look for. The following specifications are available:, _(*9)

• IsHidden (this specification will return true when a file or directory is hidden,
• HasExtension (this specification will return true when a file or directory has the specified extension),
• InPath (this specification will return true when a file is in the given path. Wildcards are allowed.)
  • note that this path should be considered relative to the $filesystem's path

Specifications can be instantiated as follows:, _(*10)

use Flyfinder\Path;
use Flyfinder\Specification\IsHidden;
use Flyfinder\Specification\HasExtension;
use Flyfinder\Specification\InPath;

$isHidden = new IsHidden();
$hasExtension = new HasExtension(['txt']);
$inPath = new InPath(new Path('mydir'));

Combining specifications

You can search on more criteria by combining the specifications. Specifications can be chained as follows:, _(*11)

$isHidden->andSpecification($hasExtension) will find all files and directories that are hidden AND have the given extension., _(*12)

$isHidden->orSpecification($hasExtension) will find all files and directories that are hidden OR have the given extension., _(*13)

$isHidden->notSpecification will find all files and directories that are NOT hidden., _(*14)

You can also make longer chains like this:, _(*15)

$specification = $inPath->andSpecification($hasExtension)->andSpecification($isHidden->notSpecification());, _(*16)

This will find all files in the given path, that have the given extension and are not hidden., _(*17)
