Hi Zac good to catch up with you at WordCamp London!

It’s not the front end display I’m struggling with but rather the backend. I want to create a code mirror block which will allow me to edit text in a specified language. So I need to have a way to tell the <CodeEditor> component on the backend what language it should be using. I’ve tried looking at the CodeMirror docs and the Gutenberg docs but I’m scratching my head because the <CodeEditor> component doesn’t seem to have a property for it’s language mode: https://github.com/WordPress/gutenberg/tree/master/components/code-editor

Possibly this element is only intended for html, css and js?

Anyway I’ll have a play around with it.
