Find a way to link local files (e.g. images) in our markdown files.

I agree. But we should first discuss how to solve this best, before starting any implementation, please.

Hi @anybody, we can use \Drupal::service ('extension.list.module')->getPath('my_markdown_module)to get the relative path of the module.

We can define it at the top of the php file or globally to use it according to our need.

ChatGPT thinks this is the right regex to match the image url inside a markdown image decleration, feel free to test it out!

/!\[.*?\]\((.*?)\)/

Ok I think I first need to have a look here and eventually discuss this finally. Let's do it, when it's needed.

If this is a relative URL NOT starting with / […] leave untouched

I think this case should also be prefixed with the module path, as this would still give access to more folders than it should (security). /img.png could easily be something like /my-secret-module/secrets.png, which the markdown should not have access to.

In my opinion the best approach to this would be to only allow relative URLs in one of these forms as these can all safely be redirected to the path within the module:
