MathJax interferes with Markdown fences

[jywarren]

What happened just before the problem occurred

@khamba posted some code with code fences, like:

// code here

You can see the original raw markdown code here: https://publiclab.org/notes/raw/14004

But the mathjax library we've added parsed it and tried to evaluate it as a latex math expression, and caused an error:

Mathjax is included here: https://github.com/publiclab/plots2/blob/master/app/views/layouts/application.html.erb#L20

@vincegando had previously set Mathjax to use the default delimiters: e09451e

I wonder if we can specify things differently to avoid conflicting with code fences? I think we need to read some of the MathJax documentation to check.

I would like to help for this. Will start reading MathJax documentation and inform about suggestions.

According to this post we may need to change the CDN

Ah -- can you look on npmjs.org to see if we can just include it directly?

Yep, it's there.
https://www.npmjs.com/package/mathjax

[jywarren]

oh great -- well, we should be able to link to it either by its name or by direct URL in https://github.com/publiclab/plots2/blob/master/bower.json -- and then change the URL that had been pointing to the CDN version. Can you give that a try?

Oh found the issue. We are using RDiscount to render the markdown in published notes. And the issue is current rdiscount gem version does not support fencing code blocks with ```. Found these details using following articles.
article 1 :Here in Code section it says nothing about fecing code blocks with ```.
article 2 :Here it states that older versions of RDiscout does not support ``` fences.

So I will try including the current version of gem in Gemfile.

Doing that solved the issue. now it is rendering correctly as follows.

Fantastic!!! Great work!
