The code formating engine used by SO (google-code-prettify) seems dead (lasts two commits have been made on sep 2013 & mar 2014). As stated on this post, each code-formatting request have to be redirected to this project.

In my case, I was wondering if C# async/await keywords highlighting could be improved on SO, but the issue is opened since 2 years......

Even if similar question have already been asked, I'm not talking about choosing the better framework over another. IMO, the problem is about future language support and new language features (like the "new" C# async/await).

Since this project is dead, shouldn't SE/SO take it in consideration and either replace google-code-prettify by another alternative, or make the SE dev-team collaborate on this project or fork it to resuscitate it and make things happens ?

  • Good observation. It looks like one-man-show project ran by Mike Samuel and his priorities might have changed. You can certainly contribute or even take over the ownership responsibilities. It's open source anyway. @DeerHunter yes, all active Google Code projects should move to GitHub till August 2015

  • There's also the lack of syntax highlighting for VimScript, especially the vi.SE site could benefit a lot from that. I wanted to code this last week, but after seeing the lack of activity decided it wasn't worth it ... I'm not sure if actually switching to another highlight engine is the best way to go ("don't fix what ain't broke"), but perhaps a SE fork might be worth considering? Commented Mar 15, 2015 at 18:25

  • code-prettify is certainly dead. Many languages are missing, and completed pull requests are sitting around for years with no approvals. Commented Jan 22, 2019 at 10:14
  • Looks like highlight.js is now used, refer to this post for details. Commented Sep 21, 2020 at 12:50

We've officially switched to highlight.js network-wide. See the announcement post for more details.
