Hi @Pierstoval,

Create a standard DI's Definition with any DI way
...
For now, there is no way to do it

Have you looked at using the MarkdownConverter instead? It's the base class for CommonMarkConverter and is designed for this exact use case! 🙂

You'd need two DI definitions:

• One for the Environment
  • Pass the config array into the constructor
  • Add calls to the addExtension() method
• One for the MarkdownConverter
  • Pass a reference to the Environment service into the constructor

Give that a try and let me know if that works for you.

@colinodell The problem in that case mostly comes from TwigExtra, since the Twig\Extra\Markdown\LeagueMarkdown class depends specifically on League\CommonMark\CommonMarkConverter.

I can indeed create a definition for the League\CommonMark\Environment\Environment class, but as said in the first post, there is no way to inject it in League\CommonMark\CommonMarkConverter. In this PR I had only two choices: allow adding extensions from the Converter (as a wrapper), or add an optional Environment parameter to the constructor. Since the config is already there, I decided it was less costly to execute ->addExtension later (since Symfony DI allows it)

Edit: I also wanted to locally extend CommonMarkConverter to at least find a workaround, but it's final 🙈
