# Customize markdown processor

I am integrating Katex in my blog.

Some problem with blackfriday:

I have to put the following code into a

to make it work, as explained in:

(mathjar and katex are similar to each other)

$$\begin{array}{clc} (3, 4) & \rightarrow f(x) = (3x + 4) % 12 \ x = 0, 1, 2 … 11 & \rightarrow f(x) = 4, 7, 10, 1, 4, 7, 10, 1, 4, 7, 10, 1 \end{array}$$

It is because & is interpreted as &amp; which can not be recognized by Katex.

I need to change makedown processor to automatically render a $$…$$ formule block into a

, then & is really a &. No more escape is needed here.

I am not sure whether the above is possible, since it seems that Hugo does not allow blackberry configuration, not even mention change rendering the markdown processor.

Any help is highly appreciated.

No, but we do allow some Blackfriday configuration. Have a look in the doc. Not sure if it helps your case, though …

DId you solve the problem? I have similar problem.
