Is line numbers considered "highlighting"? I mean, I get why you would want it but I never would have thought to ask for it.

It does seem more appropriate to have a separate module for line numbers. I would definitely understand the separation of concerns argument, but the maintainer instead makes some sort of emotional appeal about clutter and simplicity to explain why there is no line number support.

Clutter and simplicity is not an emotional argument. It becomes verifiably more difficult to maintain a code base with each new line. And since he's the one doing the maintaining, his position seems quite reasonable.

Secondly, he seems to have a strong aesthetic aversion to line numbers, and I can totally respect that. Frankly, among popular open source projects, those whose developers have the strongest sense of style and design and usually (not always) the best.

Many popular syntax highlighting libraries do include this functionality. For example, the popular Python syntax highlighter "Pygments" supports line numbers[0].

I personally use Prism.js for my blogging, which is what Smashing Magazine and CSS-tricks uses. Prism includes line numbers.

I like Prism so far and don't have any issues with it yet
