Would you consider creating a prism js addon? The code formatting options here are not very convenient to use and I really badly need this functionality.
I'm sorry, but not yet. I suggest you check out the following support topic it should help you: https://wpforo.com/community/how-to-and-troubleshooting-2/wpforo-and-syntaxhighlighter-evolved/#post-21167
Thank you for that link. I was actually able to add prism to the forum tinyMCE editor with help of a Stackoverflow user. The only problem now is that the forum doesn't apply the styling. It only works in the editor.
Is there a way to show the styling in the post as well? CSS and JS code is added, the forum posts just ignore it.
