Since the syntax highlighter is now highlight.js it would be great to finally get some syntax highlighting for Julia code on Stack Overflow and other sites that might need this tag. Julia is one of the supported languages in highlight.js.
With over 11k questions already, this will benefit a lot of people.
Answers to some comments to add some more motivation.
If you write a feature request please outline why this would benefit the entire community.
This question does not make sense to me; the entire community is not benefiting from Python syntax highlighting either, the Python community is. Likewise, the Julia community will benefit from Julia syntax highlighting. The Julia tag already has more activity than some other language tags that are already included in the highlight.js file loaded by the site:
so it would definitely be worthwhile to include Julia.
Or else why would the benefits for a few users outweigh the costs for all other users?
I am not sure what (noticeable) cost there would be for adding another language, library size(?). Presumably a "one-time" cost since the browser would cache it. Anyway, here is the library built with the current supported languages with and without Julia:
Building highlight.js. (Current languages)
highlight.min.js : 136002 bytes
highlight.min.js.gz : 46091 bytes
Building highlight.js. (Current languages + Julia)
highlight.min.js : 139505 bytes
highlight.min.js.gz : 47477 bytes
So an approximately 1.5 KB increase. If you compare this to other content on the site (400 KB for the top question with the Julia tag) this would be less than a 0.4% increase.
