It would be great to have a Code Syntax Highlighting for the most common programming languages in the Atto editor. I know there is the GeSHi Filter https://docs.moodle.org/31/en/Code_syntax_highlighting, but it hasn't been updated in a while and no one seams to have it running on Moodle Version 3.1. so far. Furthermore I think the filter only supports the non-standard TinyMCE-Editor.
My Question: Is anyone running another filter/plugin for Syntax Highlighting and is satisfied with it?
Thank you in advance for your inputs!
