Removal of the .codehilite class makes it difficult to see what's changed, such as the addition of the /* Comment.Hashbang */ among several others. There's some conversation happening in #6 regarding the wrapper class used. Regardless, the Makefile in this PR will save people time. 😅

Thanks I'll add the class back in. I doubt the pr will ever be merged though since #6 has been open for two years now, but it's worth a shot.

Hey, either way it'll help :) Seeing your diffs helped me make this already: https://github.com/comfusion/atom-one-pygments

commit 146834e addresses #6

@richleland would you do the honors? Many many websites are turning to JS for highlighting as a result of #6

[cs01]

They can also just use my fork :) https://github.com/cs01/pygments-css. I'm an active github user and respond quickly to updates.

But I agree with @jhabdas, @richleland, this repo is widely used but out of date. If you no longer want to maintain it, pass the torch on to someone who will.

Thanks for submitting @cs01. To be honest I wasn't aware it was used widely - I haven't done anything with pygments in years or worked on anything using it. Issues (4 in 8 years) and PRs (the last coming in Oct 2015) have been rare for the repo, so I don't keep as close an eye on it, but happy to keep closer watch moving forward.

Thanks again for the PR and nudging!
