Add syntax highlight to code blocks

[Mailaender]

This creates nicer previews on GitHub and when reading documentation with @eclipse-theia.

@Mailaender thanks.

@merks WDYT?

The renderer for the website doesn't interpret it:

but the github page does:

But it does no harm to have it.

Is such a "rendered" way deployed anywhere at all?

I'm not sure I understand the question. Yes all the markdown content of all the project are rendered in the website.

E.g.,

https://eclipse.dev/eclipse/markdown/?file=eclipse-platform/eclipse.platform.ui/master/docs

@Mailaender

I don't really have time to review every line. May I trust that you've reviewed this content relatively carefully?

[akurtakov]

I really missed the fact that all these markdown files are listed that way at https://eclipse.dev/eclipse/ . Thanks @merks !

One of the nice features too is that one can get a live preview of all your markdown changes (if you've used the Oomph setup for the website repository):

I thought it good to record here that it should be possible do highlighting in the renderer too:

https://www.npmjs.com/package/marked-highlight

I just don't have the cycles for such work.

I did all the changes manually, skimming through the code with Markdown preview enabled. Removed some stray new lines, and I also had trim whitespaces enabled in the editor, which is why this is a bit noisy. Sorry.

I went through the changes and havent' spotted anything wrong. Merging.

Absolutely no need to apologize. I trust that you did a good job and I am grateful! 🙏
