Editing enclosing <pre> tag attributes for an IndentedCodeBlock with AttributeProviderFactory

I’m new to commonmark-java, and am trying to figure out how to apply a CSS class to all <pre> tags surrounding an IndentedCodeBlock. I was successfully able to apply attributes to Header and BlockQuote nodes, but if I match a Node with IndentedCodeBlock and add a class to the attribute map, then it applies it to the <code> tag in the HTML it renders.

I think what’s happening here is that <pre> isn’t a Node, just an artefact of the way the HtmlRenderer renders the IndentedCodeBlock (and FencedCodeBlock) Nodes, and so I’m never able to override the attributes for the <pre> tag because it never goes through the AttributeProviderContext as a Node.

If I’m understanding this correctly, the only way to do this would be to override the rendering itself for FencedCodeBlocks and IndentedCodeBlocks.

Do you think it makes sense to allow for overriding the attributes of tags where more than 1 set of tags is generated per node? Perhaps the AttributesProvider could provide attributes for the outer tags first with an override for providing attributes inside of the nested structure?

Implemented and released in version 0.8.0 now. Thanks for reporting! 😃

Yep, I meant calling it multiple times, with an additional string argument.

The Map<Map<... seems a bit too complicated and error-prone (what happens when implementation removes a whole tag, or adds new ones, etc).

I plan to look into this tomorrow!
