I get lots of email diffs from various projects that I work on. Reading these diffs in the Gmail interface can be a bit of a slog without basic features like syntax highlighting. Does anyone know something like a Chrome Extension that can do syntax highlighting inside arbitrary websites so I can see these things in a usable fashion?

I'm specifically looking for gmail but arbitrary websites is fine for posterity.

  • If you are familiar with css you can create your own stylesheet for GMail which highlight what you want. Mar 13, 2014 at 18:06

While it does not have the same ample supply of languages that some of the file-extension-based highlighters like Syntaxtic and Sight do, Instant Syntax supports "Java, Markup Languages, CSS, C-like languages, C#, C++,Python, SQL, PHP and JavaScript." and lets you highlight text and click a button to see it colored according to the language syntax of your choice. I use it on CodeGolf from time to time and can verify it works.
