ABNF boxes
Is your feature request related to a problem? Please describe. WebIDL syntax boxes are nice...
Describe the solution you'd like it would be nice to have nice boxes for ABNF too, just like WebIDL ones.
So, <pre class="abnf"> would give a nice box too 🎁
ENBF too.
FWIW, I have an ABNF to/from EBNF transpiler, validator and parser generator in Ruby I’ve thought could be ported to JavaScript sometime. https://github.com/dryruby/ebnf
Oh nice, @gkellogg! we should also add EBNF as a supported highlight language. We currently only support ABNF, but EBNF wouldn't add much to the size of the highlighter code.
