In a LiveView module, I use Earmark to convert markdown to HTML. In my markdown, I have Elixir code snippets. I’m wondering how I might apply syntax coloring to the snippets. Does anyone know how this might be done? Thanks
Thanks for the reference. It looks promising, but unfortunately it’s not working for me yet. I’m not sure that I’m doing everything necessary. Here’s what I’ve done so far:
{:makedown, "~> 0.2.1"}
and replaced all of:
Earmark.as_html
with:
Makedown.as_html
then run:
mix deps.get
Then when I start my server, I gets lots of warnings and a compilation error (see below).
There were some other instructions regarding ExDoc but it looks like they were optional. I’ll keep poking around to see if I can see what the problem is. Please let me know if you have any suggestions.
Thanks
