request to add SAS langauge syntax highlighting in CodeRay

I submitted a request to add SAS language syntax highlighting in CodeRay. If you have a GitHub account, the least you can do is give the request a "+1".

If you have experience with (Ruby) regular expressions, you can contribute. Or if you can think of other good code examples, you are welcome to give me links or comment on the issue over at GitHub.

I have a customized set of rules for SAS code using prism.js -- that's what we use for SAS code highlighting here on SAS communities. I'll be happy to supply that if you think it might help. It's regex-based, along with a CSS file for how to color.

That would be fantastic! I would definitely use it. Is it in a GitHub repository? If it isn't to be made public, you can email it to me.

The link you posted mentions SAS support already. I'm hoping your .js is more complete than this one (origin?), though anything would be useful.

Yes, mine has more stuff!

Here's a version of it in a GitHub Gist (prism-sas.js) Also added my customized version of the prism.css file that addresses the new element types that I added.

The prism-sas.js contains basic regex patterns that are matched in precedence order. It will match patterns from the top rule down to the bottom, and when it finds a match for the token it exits. If you write a rule that isn't getting hit, it's because the token is hitting some other rule first.

These look great! Thank you for sharing.

You should submit a pull request to Prism with these. They are big improvements upon what they already have, and other SAS+Prism users will benefit.
