Highlight inside the code block

Currently I use Rouge to highlight my code. What I want to do is to be able to highlight some code with bold/red inside the code block.
Any ideas how could I do that?

I don’t think that is supported at the moment though maybe it is on their radar?


Possible alternative is to use Prism instead. It has support for highlighting specific lines of code.


Thanks for suggestion! It looks interesting, however I failed to describe what I really want to achieve. I would like to highlight specific words (not lines) inside the code block. In fact, I would even agree to drop syntax highlighting at all to get this feature.
So basically the requirements are: block of text with a monospace font + highlight any words I need. Any ideas how could I do that?
