Syntax-highlighting doesn’t show in production

Production:

Trying to isolate the Ruby environment to track down the bug.

After removing all gems (and installing nvm and updating Ruby), the syntax-highlighting is gone from dev:

$ rvm gemset empty
Warning! PATH is not properly set up, '/Users/darville/.rvm/gems/ruby-2.0.0-p247/bin' is not at first place,
         usually this is caused by shell initialization files - check them for 'PATH=...' entries,
         it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
         to fix temporarily in this shell session run: 'rvm use ruby-2.0.0-p247'.
Are you SURE you wish to remove the installed gems for /Users/darville/.rvm/gems/ruby-2.0.0-p247?
(anything other than 'yes' will cancel) > yes
installing gem /Users/darville/.rvm/gem-cache/gem-empty-1.0.0.gem --no-ri --no-rdoc.

Well, I guess the good news is that the discrepancy is gone.

[ndarville]

Restoring the gems did not fix things on dev.

[ndarville]

Newer versions of Jekyll will use Kramdown as the default Markdown parser, so it might be worth waiting it out.

https://github.com/jekyll/jekyll/issues/1929

[parkr]

@ndarville Is it specific to this one file? If so, which file?

[ndarville]

@parkr If you’re referring to the file that isn’t displaying the highlighting, it’s this one. The live version in production is here.

I haven’t been able to look at the problem for Friday-ish due to the Dropbox downtime. I also had some other things that need to be staged and pushed, when Dropbox sorts itself out, but I don’t see any of them affecting the highlighting.

[parkr]

@ndarville Ah, the triple back tick with syntax highlighting is not supported in Kramdown. In kramdown, you would need to use our highlight liquid tag:

{% highlight html %}
<!-- HTML -->
{% endhighlight %}

RedCarpet has support for the triple back ticks with syntax highlighting.

[ndarville]

Ah, I guess that’s it. It did work locally at one point with some of the installed Ruby gems, but if it’s not supported to use anything but the highlight tag, I’ll go with that. :)

I’ll make and push the changes, when Dropbox is up and working and close the issue accordingly.

Thanks for the help, @parkr.

[parkr]

My pleasure! And FWIW, Dropbox is up and working for me. :smile_cat:

[ndarville]

Fixed in b89ec83f12790b94e26e1ff9975fb466cffbcdc5. God damn Dropbox to hell.
