Greetings,

I am working on an application that uses markdown and supports code blocks. We also let users mark fragments of code blocks as if with a yellow marker.

We currently have a lua filter that does the marking, but it does not work in combination with syntax highlighting. It never returns the CodeBlock and so the highlighter is never called. I have determined that in order to make the two work together, I need to take the following steps:

- determine where the marking is supposed to go

- remove the [mark] tags and send the code block to the highlighter

- insert the marking in the resulting highlighted code.

However, I have not found a way to access highlighted code, or call the highlighter, from a lua filter. Is there a way to do that or is my plan doomed to failure?

I am also open to other suggestions.
