Add syntax highlighting to code examples in docs

[trosel]

Syntax highlighting to code examples (especially in tutorials) would help with readability / helping beginners see that it's not just line noise.

[coke]

We are already doing syntax highlighting.

Feel free to re-open if you have a specific example that isn't getting syntax highlighting.

[trosel]

It must have broken everywhere then.

You can see my UA info here: http://www.whatsmyua.com/#Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36

And you can see a screenshot below.

I double this issue. I thought highlighting was turned off for some reason. Latest firefox.

I do see highlighting classes in html, but they are still not colored. It used to work for me some time ago.

Yeah, I checked earlier, the highlighting transformation appears to be happening in most places but it isn't loading the stylesheet I think.

@samcv noted that one of the nodepm packages we depend on changed all their class names without warning. b1d51f1 was supposed to help, but I don't see any changes on the site yet.

see also 0193f3e and 9525968

[samcv]

docs.perl6.org is fixed now as of 9525968
Closing!

[trosel]

It looks like some are fixed depending on what css is:

class="editor editor-colors" works, but class="pod-block-code" does not.

[samcv]

That is not the same problem. That is related to what is in the pod6 files the docs are created from. Anything tagged as pod-block-code usually means that's what the block was inside tho doc file

=begin code :allow<B L> that is on the page you showed the screenshot of. If it has :allow then it renders as Pod not as perl 6 code

[trosel]

@samcv Should it be left open as a "someone can feel free to change this so it's consistent" type of task?

[samcv]

I think there's another ticket for that, not sure which

[samcv]

But it's not the original issue, which is why I closed it. It's a separate problem

[samcv]

If you can't find one, please open an issue for it.
Make sure to paste this into the issue:

The pod6 file has :allow in the code designation:
=begin code :allow<B L> . If it has :allow then it renders as Pod not as perl 6 code

Thanks

@WildYorkies I have opened an issue here for this https://github.com/perl6/doc/issues/1164

I also wrote my proposed solution for this, and a more detailed explanation of why this currently happens.
