Installation
Library requires fswatch - a cross-platform file change monitor with multiple environments.
You can install this package like this:
composer global seregazhuk/reactphp-fswatch
Usage
First of all, you create a watcher object providing a loop and fswatch command that
you are going to run. For example if you want to listen to changes inside src
directory:
$loop = \React\EventLoop\Factory::create(); $watcher = new \Seregazhuk\ReactFsWatch\FsWatch('src', $loop,); $watcher->run(); $loop->run();
Once there are changes in the directory the watcher fires change
event that contains an
instance of Change
object. To detect change you can listen to this event and
handle the event object:
$watcher->on( 'change', static function (Change $event) { $type = $event->isFile() ? 'File' : 'Dir'; echo $type . ': ' . $event->file() . ' was changed' . PHP_EOL; } );
Also, you can use a helper method onChange
:
$watcher->onChange($callable);
To stop listening for filesytem use method stop()
:
$watcher->stop();
Filesystem Changes
On every change you receive Change
object that contains different details about
an event that happened in the filesystem. It has the following helper methods to examine the change:
file()
- filename or a directory that has changed.isFile()
- whether a file was changed or not.isDir()
- whether a directory was changed or not.isSymbolicLink
- whether a symbolic link was changed or not.isLink()
- the object link count has changed.noOp()
- no changed were detected.attributeModified()
- the object’s attribute has changed.ownerModified()
- the object’s owner has changed.created()
- the object has been created.removed()
- the object has been removed.renamed()
- the object has been renamed.updated()
- the object has been updated.
