In a Discourse forum for techies discussing code in a specific language I’d like to be able to highlight something in a code block. For example the O/P posts some, broken, code and I fix it up. The user has to carefully read my improved code to see what I have changed, and putting a comment in the code like:
xxx = yyy <— I MADE A CHANGE HERE
is a bit lame!, particularly on a complex line.
I suppose, ideally, it would just be a background colour to highlight a section, but if it was possible to put some sort of [color=red] or similar tags into the code that would provide more facilities to people which more artistically then me!
