Pandoc reaches inside math within dollars

Pandoc reaches inside math within dollars

Hi Folks,

I'm trying to figure out how to have pandoc put a span with class math or 
class math+display around math but not do anything inline.

Here is my markdown fragment:

➜  Blogs cat a.md
Inline $\alpha +\beta$ is good...


$$
Sensitivity \equiv TPR = \frac{TP}{OP} = P(T+ | D+)  = 0.938
$$


$$
Specificity \equiv TNR = \,\,\frac{TN}{ON} = \,\,P(T- | D-)
$$




Thus, (given no $disease$ you either test positive or negative):


$$ Specificity = 1 - P(T+ | D-) = 0.956 $$




Solving for the probability of a positive test, we get:


$$
P(T+ | D-) = 1 - 0.956 = 0.044
$$




Here is simple output:
➜  Blogs pandoc  a.md -t html -f markdown
[WARNING] Could not convert TeX math '
  Sensitivity \equiv TPR = \frac{TP}{OP} = P(T+ | D+)  = 0.938
  ', rendering as TeX
[WARNING] Could not convert TeX math '
  Specificity \equiv TNR = \,\,\frac{TN}{ON} = \,\,P(T- | D-)
  ', rendering as TeX
<p>Inline <span class="math inline"><em>α</em> + <em>β</em></span> is good
…</p>
<p><br /><span class="math display">$$
Sensitivity \equiv TPR = \frac{TP}{OP} = P(T+ | D+)  = 0.938
$$</span><br /></p>
<p><br /><span class="math display">$$
Specificity \equiv TNR = \,\,\frac{TN}{ON} = \,\,P(T- | D-)
$$</span><br /></p>
<p>Thus, (given no <span class="math inline"><em>d</em><em>i</em><em>s<
/em><em>e</em><em>a</em><em>s</em><em>e</em></span> you either test 
positive or negative):</p>
<p><br /><span class="math display"><em>S</em><em>p</em><em>e</em><em>c</em
><em>i</em><em>f</em><em>i</em><em>c</em><em>i</em><em>t</em><em>y</em> = 1 
− <em>P</em>(<em>T</em> + |<em>D</em> − ) = 0.956</span><br /></p>
<p>Solving for the probability of a positive test, we get:</p>
<p><br /><span class="math display"><em>P</em>(<em>T</em> + |<em>D</em> − ) 
= 1 − 0.956 = 0.044</span><br /></p>



You can see that pandoc reaches inside and puts "ems". Same thing 
with pandoc  a.md -t html -f markdown+tex_math_dollars.

If i use gfm for example, this goes away, but then pandoc still reaches in 
and replaces \, (backslash comma) by comma. Happens with and without raw tex

➜  Blogs pandoc  a.md -t html -f gfm+raw_tex
<p>Inline $\alpha +\beta$ is good...</p>
<p>$$ Sensitivity \equiv TPR = \frac{TP}{OP} = P(T+ | D+) = 0.938 $$</p>
<p>$$ Specificity \equiv TNR = ,,\frac{TN}{ON} = ,,P(T- | D-) $$</p>
<p>Thus, (given no $disease$ you either test positive or negative):</p>
<p>$$ Specificity = 1 - P(T+ | D-) = 0.956 $$</p>
<p>Solving for the probability of a positive test, we get:</p>
<p>$$ P(T+ | D-) = 1 - 0.956 = 0.044 $$</p>


Very confused! Please help!

Thanks, this is rather interesting. Works on calling --mathjax with nothing 
( i am not in standalone mode), Do you understand the reason why its done 
this way? I had expected raw_tex would leave things alone, but perhaps it 
does make sense that invoking an extra math processor would work. Would 
have loved for it to use the dollar syntax instead of the \( or \[ syntax, 
though!

Re: Pandoc reaches inside math within dollars

[John MacFarlane]

Well, in many cases you don't want tex math to be left as
is; you want it to be converted in a way that makes sense
for the output format (e.g., an equation object in MS Word,
or an eqn equation for groff ms, or mathml for XML formats).
Pandoc defaults to "faking it with unicode," which is sensible
in all formats, unless you tell it to do something else.
