Math in marginnote (and change of MathJax id)

[ekstroem]

Hi.

This may just be a liquid problem (or rather a user problem of not understanding the liquid tags) but I'd like to add a wee bit of inline math to a margin note with the following code

{% marginnote 'ID9' 'Yada yada yada. A {% m %} X^2 {% em %} test for this table yada yada yada' %}

However, that results in an error

Liquid Exception: Unmatched double quote:

and I'm guessing that I cannot nest liquid tags inside one another.

One option is to change the math start and end tags to $ (for inline) and $$ (for block) as is possible with other configurations of MathJax. Would doing that break a lot of things (and if no: can anyone point me in the right direction for this)?

let me look into it. The issue may be a 'tags within tags' thing. But if we can just use the default '$' and '$$' tags that are baked into Mathjax, that may be the way to go.

So I hadn't looked into this before, but now that I do, it turns out Jekyll's default Markdown renderer has built-in MathJax support http://kramdown.gettalong.org/math_engine/mathjax.html

So @ekstroem either of these snippets work great!

{% marginnote 'ID9' 'Yada yada yada. A $$X^2$$ test for this table yada yada yada' %}

{% marginnote 'ID9' 'Yada yada yada. A \\(X^2\\) test for this table yada yada yada' %}

@clayh53 Apparently there is no need for the mathjaxtag.rb plugin.

So using $ and $$ for equations is easy to setup by how you load mathjax into the page. See http://docs.mathjax.org/en/latest/start.html#tex-and-latex-input

Oh, snap! I do remember reading some documentation about Kramdown having this ability. That makes it easy!

Great! I can confirm that

{% marginnote 'ID9' 'Yada yada yada. A $X^2$ test for this table yada yada yada' %}

works. I previously had some problems with $ signs in the main text (in the sense that they were rendered as dollar signs and not starting/ending math blocks) - I'll try to see if I can reproduce this. In any case: this works!

Cheers

Using $ for inline equations is disabled by default in mathjax See #38 for how to enable it.

[ekstroem]

Hmm. It works out of the box here at my end (what I really mean is that I cannot remember what I've tinkered with previously but I cannot see a change like fix #38 anywhere. In any case there's a good solution, and I'm happy :)

Ok cool.
