A simple resource watcher for getting changes of your filesystem.
Use Composer to install this package:
composer require yosymfony/resource-watcherThis package uses Symfony Finder to set the criteria to discover file changes.
use Symfony\Component\Finder\Finder;
use Yosymfony\ResourceWatcher\Crc32ContentHash;
use Yosymfony\ResourceWatcher\ResourceWatcher;
use Yosymfony\ResourceWatcher\ResourceCachePhpFile;
$finder = new Finder();
$finder->files()
->name('*.md')
->in(__DIR__);
$hashContent = new Crc32ContentHash();
$resourceCache = new ResourceCachePhpFile('/path-cache-file.php');
$watcher = new ResourceWatcher($resourceCache, $finder, $hashContent);
$watcher->initialize();
// delete a file
$result = $watcher->findChanges();
$result->getDeletedResources() // array of deleted filenames. e.g: "/home/yosymfony/README.md"Every time the method findChanges() of the class ResourceWatcher is invoked,
it returns an object type ResourceWatcherResult with information about all the
changes producced in the filesystem. The ResourceWatcherResult class has the following methods:
getNewFiles(): Returns an array with the paths of the new resources.getDeteledFiles(): Returns an array with the paths of deleted resources.getUpdatedFiles(): Returns an array with the paths of the updated resources.hasChanges(): Are they changes in your resources?.
Two hashing classes are included in the package:
Yosymfony\ResourceWatcher\Crc32ContentHash, which hashes the content of the fileYosymfony\ResourceWatcher\Crc32MetaDataHash, which hashes the filename and its last modified timestamp
To rebuild the resource cache uses rebuild() method of the class ResourceWatcher.
Using relative paths with the resource cache is possible thanks to the
ResourceWatcher's method enableRelativePathWithCache:
$watcher = new ResourceWatcher($resourceCache, $finder, $hashContent);
$watcher->enableRelativePathWithCache()The ResourceWatcherResult object will has relative paths.
