README

NOT a production-ready code!

Use at your own risk.

But I will be happy if you will get inspired by this 😉

Purpose

I should be able to create a standalone, independent library to control directories by a JSON configuration and CLI. With use of object-oriented programming and PHP (in a version of my choice).

Standalone

This library should be runnable just by a terminal emulator and a PHP executable.

for example:

php ./bin/dirsync --dry-run

Independent

No other libraries should be used (not even shinnies as the Symfony Console).

Usage

Create a JSON file with configuration directives:

• key starting with a hash sign # is processed as an Action, value (scalar, array, object...) is then used as a parameter to Action->runAction itself
  • see \JaroslavTyc\DirSync\Actions\ActionInterface for details
• key not starting by a hash sign # is considered as a dir name and is used for Create Dir Action directly as a value
  • any value pointed by that JSON key will be ignored (hint: use null there)
  • see \JaroslavTyc\DirSync\Actions\CreateDirAction for details

for example:

{
    "NewDirByDirSyncDirectName": null,
    "#CreateDir": "NewDirByDirSyncCreateDirAction"
}

Process it:

php ./bin/dirsync --json-config=json_config_file_for_dir_sync.json

Should create two empty directories NewDirByDirSyncDirectName and NewDirByDirSyncCreateDirAction in a current working directory.

More Actions

Create your own Action implementing \JaroslavTyc\DirSync\Actions\ActionInterface and register them to \JaroslavTyc\DirSync\ActionsRunner.

for example:

<?php
namespace JaroslavTyc\DirSync;
use JaroslavTyc\DirSync\Actions\ActionInterface;

class DeleteDirAction implements ActionInterface {
    public function getName() : string {
         return '#DeleteDir';
    }
    public function runAction($context,string $workingDir, bool $dryRun) {
        // some nasty destroying code
    }
}

$actionsRunner = new ActionsRunner();
$actionsRunner->registerAction(new DeleteDirAction());

Original task

All of this comes from the original Flowmedia task.

Differences against original task

• root dir renamed to working dir, as root dir has specific meaning in Linux
• working dir (formerly root dir) has to be provided explicitly to the synchronization method itself to avoid accidents and confusion
• all configuration options, except working dir, are wrapped by interface DirSyncOptionsInterface, most of them originally enclosed by original task DirSyncInterface

Installation

The easiest way is to get it via composer:

php composer.phar require jaroslavtyc/flowmedia-dir-sync
