Implementing an Extension

[gamejerksnet]

So I followed the Wiki page and created an Extension class. What I don't know how to do is tie it into my Parsedown package telling it to use my new class while parsing text. Below is my new class:

<?php namespace App\Extensions;

use App\Repositories\User\UsersRepository;
use Parsedown;

class Extenstion extends Parsedown {

    /**
     * @var UsersRepository
     */
    private $usersRepository;

    function __construct(UsersRepository $usersRepository)
    {
        $this->InlineTypes['@'] []= 'UserTag';

        $this->inlineMarkerList .= '@';

        $this->usersRepository = $usersRepository;
    }

    protected function inlineUserTag($Excerpt)
    {
        if (preg_match('/^@([^\s]+)/', $Excerpt['text'], $matches))
        {
            $urlToUser  =   $this->usersRepository->findByDisplayName($matches[1])->url();

            return array(
                'extent' => strlen($matches[0]),
                'element' => array(
                    'name' => 'a',
                    'text' => '@' . $matches[1],
                    'attributes' => array(
                        'href' => $urlToUser,
                    ),
                ),
            );
        }
    }

}

The purpose of this extension is to turn @trinyx into a link to that user but keeping the same text.

Well, you should just use your class instead of Parsedown.

So instead of:

<?php

$Parsedown = new Parsedown();
$markup = $Parsedown->text('# Some Markdown Here');

you would use:

<?php

$Parsedown = new App\Extensions\Extension($userRepository);
$markup = $Parsedown->text('# Some Markdown Here with @usernames');

This is quite literally an extension. You just extend a class and use OOP. 🍻

Oh lol I'm using Parsedown through Laravel and didn't realize it was like that. Thanks.
