I'd like to to highlight a part of a literal/listing/source block "manually" in AsciiDoctor. Is there any way to do so?
E.g. I'd like to add a class or just a single "strong/b" to some parts, like following.
[literal]
....
000000: 1234 7364 2832 9323
000008: 4823 [.red]#ffff# 4634 7434
000010: 1234 7364 2832 9323
....
You need to turn on quote substitution. Change
[literal]
to
[literal, subs="quotes"]
But makes sure your literal block doesn't contain anything else that might be misinterpreted as a quote substitution.
