Reference to LaTeX math in ox-hugo
In Org-mode, you can reference LaTeX math, with \ref{eq:1},
but in ox-hugo it does not work by default.
This math sinippet:
(org)
\begin{equation}
\label{eq:01}
y = ax + b
\end{equation}
this puroduces this:
\begin{equation} \label{eq:01} y = ax + b \end{equation}
Here I referece Eq. \ref{eq:02} (Eq(\ref{eq:02}).
Without the settings below, this reference does not work.
Make static/mathjax-config.js as follows
(take from ox-hugo’s test site):
Code Snippet 1: static/mathjax-config.js
(javascript)
window.MathJax = {
displayAlign: "center",
displayIndent: "0em",
"HTML-CSS": { scale: 100,
linebreaks: { automatic: "false" },
webFont: "TeX"
},
SVG: {scale: 100,
linebreaks: { automatic: "false" },
font: "TeX"},
NativeMML: {scale: 100},
TeX: { equationNumbers: {autoNumber: "AMS"},
MultLineWidth: "85%",
TagSide: "right",
TagIndent: ".8em"
}
};
And call it from a template which calls Javasctipt (like layouts/partial/header.html):
(html)
<script src='https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.4/MathJax.js?config=TeX-MML-AM_CHTML' async></script>
<script src="{{ "mathjax-config.js" | absURL }}"></script>
Lets' reference some equations.
(org)
\begin{equation}
\label{eq:02}
y = ax + b
\end{equation}
\begin{equation} \label{eq:02} \y = ax + b \end{equation}
Here, referencing Eq. \ref{eq:01}.
