How to write latex using org mode? Minmum things you need to know.

By Anak Wannaphaschaiyong

What you need to know to start writing latex in org mode is to understand how org-export-dispatch include/exclude/map org mode component to latex equivalent. You can learn all about these info by reading org manual on the topic, here.

You should know a little bit about org mode header arguments and LaTeX to fully follow the blog.

In this blog, I will just present minimal info for you to start writing latex in org mode.

This is the org header for a minimum use.

From above code, you need to define things to be used in #+LATEX_CLASS. LaTeX class’s variable avaible in the header argument is defined in org-latex-class. From above you see that I define LaTeX class variable with org-latex-class.

(add-to-list 'org-latex-classes
             '("IEEE" "\\documentclass{IEEEtran}"
  ("\\section{%s}" . "\\section*{%s}")
  ("\\subsection{%s}" . "\\subsection*{%s}")
  ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
  ("\\paragraph{%s}" . "\\paragraph*{%s}")
  ("\\subparagraph{%s}" . "\\subparagraph*{%s}")))

From the doc you see that

  (class-name
    header-string
    (numbered-section . unnumbered-section)
    ...)

so, we get “IEEE” is a class name.

\\documentclass{IEEEtran} is header-string

and

("\\section{%s}" . "\\section*{%s}")
  ("\\subsection{%s}" . "\\subsection*{%s}")
  ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
  ("\\paragraph{%s}" . "\\paragraph*{%s}")
  ("\\subparagraph{%s}" . "\\subparagraph*{%s}"

is list of (number-section . unnumbered-section)

Out of these components, its worth to understand that (number-section . unnumbered-section) directly mapped to how org-export-dispatch map org header to latex equivalent.

Using the above (number-section . unnumbered-section), If you have content of org file as followed.

* first header
** second header
*** third header

First header will be map to section, second header will be mapped to subsection, and so on.

Without these defined, org-export-dispatch will map first header to enumerate and whatever that is equivalent of subenumerate, and so on. (I don’t recall the name percisely.)

I provide example of minimum content below

* First Header

Lorem $1+1$ ipsum dolor sit amet, consectetur adipiscing elit. Cras lorem
nisi, tincidunt tempus sem nec, elementum feugiat ipsum. Nulla in
diam libero. nunc tristique ex a nibh egestas sollicitudin.

\begin{equation}
1+ 1
\end{equation}

- 1
- 2
- 3
- 4

** sub header :noexport:
Mauris efficitur vitae ex id egestas. Vestibulum ligula felis,
pulvinar a posuere id, luctus vitae leo. Sed ac imperdiet orci, non
elementum leo. Nullam molestie congue placerat. Phasellus tempor et
libero maximus commodo.
* Second header
something bruh

That’s it.

Peace.
