Symfony yaml parser not working

[AndiLeni]

Hello,

I have problems with spyc in my CMS which uses its own autoloader. That’s why I wanted to switch to the Symfony Yaml Parser.

I installed device detector via composer and deleted the mustangostang/spyc folder in /vendor. I then tried to switch to Symfony like this:

use DeviceDetector\ClientHints;
use DeviceDetector\DeviceDetector;
use DeviceDetector\Yaml\Symfony as DeviceDetectorSymfonyYamlParser;

...

$this->DeviceDetector = new DeviceDetector($this->userAgent, $clientHints);
$this->DeviceDetector->setYamlParser(new DeviceDetectorSymfonyYamlParser());
echo $this->DeviceDetector->getYamlParser()) # prints DeviceDetector\Yaml\Symfony
echo 'A'; # is printed
$this->DeviceDetector->parse();
echo 'B'; # is NOT printed

Instead a Class 'Spyc' not found error is thrown. Any ideas what might be wrong with this approach?

Thanks and kind regards

Hi. When you have manually deleted something from the vendor folder, you must do

composer dumpautoload

Thanks for the suggestion. Unfortunately, this did not help. I tried using device-detector without composer, but this gave me the same error.

@sanchezzzhak It seems to be a problem with clients hints.

You may reproduce this issue with the following steps:

• install symfony\yaml via composer
• download devicedetector without composer and place in a folder device-detector
• create php file with the following content:

<?php

require_once 'vendor/autoload.php';
require_once 'device-detector/autoload.php';

use DeviceDetector\ClientHints;
use DeviceDetector\DeviceDetector;
use DeviceDetector\Parser\Device\AbstractDeviceParser;
use DeviceDetector\Yaml\Symfony as SYP;

$userAgent = $_SERVER['HTTP_USER_AGENT']; // change this to the useragent you want to parse
$clientHints = ClientHints::factory($_SERVER); // client hints are optional

$dd = new DeviceDetector($userAgent, $clientHints);

$dd->setYamlParser(new SYP());

$dd->parse();

if ($dd->isBot()) {
    // handle bots,spiders,crawlers,...
    $botInfo = $dd->getBot();
} else {
    $clientInfo = $dd->getClient(); // holds information about browser, feed reader, media player, ...
    $osInfo = $dd->getOs();
    $device = $dd->getDeviceName();
    $brand = $dd->getBrandName();
    $model = $dd->getModel();
}

as soon as I change this line

$dd = new DeviceDetector($userAgent, $clientHints);

to

$dd = new DeviceDetector($userAgent);

the error disappears.

It seems like the AppHints parser is not using the correct yaml parser.
