Text: Code-Highlight not working

[Gmentsik]

Describe the bug
When pasting / writing code and applying the code style either via the code-button there is no syntax-highlighting of the code. Since highlight.js is included in tiptap, this should work.

To Reproduce
Steps to reproduce the behavior:

1. Go to text editor
2. write any code
3. select code
4. Click on "format as code" button

Expected behavior
code shoud be syntax-highlighted

Text app version: (see Nextcloud apps page)
1.0.2
Nextcloud version: (see Nextcloud admin page)
16.0.4 Using the official nextcloud docker

This is currently not implemented because we need to have a way to load syntax highlighting rules dynamically. tiptap currently requires them to be loaded when setting up the editor: https://github.com/scrumpy/tiptap/blob/master/examples/Components/Routes/CodeHighlighting/index.vue#L18-L19

I see, so this is not bug. Importing a lot of language would be a performance loss I guess? What about having a settings page where users may configure the languages they want to import?

I'm not sure if this belongs to the same topic but as you can see in the screenshot, there are line-breaks in the code-section. I'd prefer horizontal scrollbars instead because that's what most IDEs have as default setting and most devs are used to I guess.

I'm sure there are a lot of non-devs using this app, but having an option to switch between floating and fixed width (like eg. gitlab) would make working with code or tables also lot easier.

I don't think a setting for that should be needed. But I need to dig into the tiptap code first before I can tell if the automated loading I have in mind will be suitable.

Yes, I agree that a scrollbar would be nicer there. Could you open a separate issue for that?

I just hope the rules won't be loaded from the internet (e.g. some CDN), so that code highlighting feature could still be used in Nextcloud deployments with limited access to the internet.

No they are shipped with the release ;)
