  • (2018-10-09, v:1.1) Mikael Bergström: Does not seem to work in google classroom file preview
    I am hunting for something that will allow me to syntax highlight C# files turned in by my students through Google Classroom. Classroom uses the normal Google Drive preview system to show .cs files. It, of course, does not include syntax highlighting of C# code. Instant Syntax works perfectly when previewing cs files from drive directly, but when previewing through Classroom's system, which places the preview inside an iframe, I get this error message in the js console: Uncaught DOMException: Failed to execute 'getRangeAt' on 'Selection': 0 is not a valid index. at file:///C:/Users/[redacted]/AppData/Local/Google/Chrome/User%20Data/Default/Extensions/[redacted]/1.1_0/simpleInsert.js:24:31 I'm wondering if this has anything to do with the preview being inside an iframe?

    It would be great to use this to view diff or patch contents on mail archive pages like those at: http://lists.nongnu.org/archive/html/qemu-devel/
  • (2018-06-18, v:1.1) Daniel Jackson: Doesn't work for wordpress
    Tried in the WordPress "text" post-editing window, doesn't do anything. :/ I've tried SNTX before, and while that works, the way it fights WordPress for control of rendering is less than ideal. :(

    I tried to highlight C++ code in a new gmail message. It hightlighted well but concatenated all lines into one big line, making it useless.
  • (2015-02-11, v:1.1) Paula Denlinger: Syntax
    We are looking for a way to highlight no pay customer names in Google Calendar when they are typed into a new entry. Would it be possible for you to create a custom extension that would allow us to create our own syntax look up list?
