I’d like to extend Earmark to transform #hashtag into
<a href="/some/internal/route">hashtag</a>
Hashtags should only be transformed if they are inside of a string node, so I need to inspect the AST.
I’ve been looking through the Earmark docs and I don’t see a clear way to do this. I don’t think I can use map_ast as it says a string node must return a string.
I’ve found one example of something similar here:
It looks like they using Enum.map on the ast, but I don’t fully understand the transform_ast_node_text function, particularly the bits that pattern match on binary data. I hope I can do something simpler.
Any help is appreciated, thanks!
