Description

md2ltx uses Pandoc to transform Markdown files into LaTeX, which pdflatex then uses to generate a final PDF. This workflow supports most of Markdown’s core syntax plus many Pandoc extensions. Below is a high-level overview of how Pandoc typically converts various Markdown constructs into LaTeX. For full details, refer to Pandoc’s official documentation.

---

1) Headings

• Markdown

# Heading 1  
## Heading 2  
### Heading 3

• Pandoc → LaTeX

\section{Heading 1}  
\subsection{Heading 2}  
\subsubsection{Heading 3}

Pandoc chooses \section, \subsection, etc. based on the heading level. It also supports underline-style Markdown headings with “===” or “---” for level-one and level-two headings.

---

2) Emphasis & Strong Emphasis

• Markdown

*emphasis* or _emphasis_  
**strong emphasis** or __strong emphasis__

• Pandoc → LaTeX

\emph{emphasis}  
\textbf{strong emphasis}

---

3) Inline Code

• Markdown

`inline code`

• Pandoc → LaTeX

\texttt{inline code}

---

4) Code Blocks

• Markdown (fenced)

```  
a = 1  
b = 2  
```

• Pandoc → LaTeX (by default)

\begin{verbatim}  
a = 1  
b = 2  
\end{verbatim}

With certain options, Pandoc can use different LaTeX environments (e.g., listings).

---

5) Lists

• Unordered (Markdown)

- item 1  
- item 2  
- item 3

• Pandoc → LaTeX

\begin{itemize}  
\item item 1  
\item item 2  
\item item 3  
\end{itemize}

• Ordered (Markdown)

1. item 1  
2. item 2

• Pandoc → LaTeX

\begin{enumerate}  
\item item 1  
\item item 2  
\end{enumerate}

---

6) Links & Images

• Link (Markdown)

[Pandoc](https://pandoc.org)

• Pandoc → LaTeX

\href{https://pandoc.org}{Pandoc}

• Image (Markdown)

![Alt text](image.png)

• Pandoc → LaTeX

\includegraphics{image.png}

By default, \includegraphics is placed without floats. You can add captions or figure environments using extended syntax or metadata.

---

7) Blockquotes

• Markdown

> This is a blockquote.

• Pandoc → LaTeX

\begin{quote}  
This is a blockquote.  
\end{quote}

---

8) Horizontal Rules

• Markdown

---  
***  
___

• Pandoc → LaTeX

\hrule

---

9) Footnotes (Pandoc Extension)

• Markdown

This is some text with a footnote.[^1]

[^1]: This is the footnote text.

• Pandoc → LaTeX

This is some text with a footnote.\footnote{This is the footnote text.}

---

10) Tables

• Markdown (simple pipe table)

| Column1 | Column2 |  
|---------|---------|  
| Val1    | Val2    |  
| Val3    | Val4    |

• Pandoc → LaTeX

\begin{table}  
\centering  
\begin{tabular}{ll}  
\hline  
Column1 & Column2 \\  
\hline  
Val1    & Val2    \\  
Val3    & Val4    \\  
\hline  
\end{tabular}  
\end{table}

---

11) Math & LaTeX Blocks

• Inline Math

$E = mc^2$

• Pandoc → LaTeX

\(E = mc^2\)

• Display Math

$$  
E = mc^2  
$$

• Pandoc → LaTeX

\[  
E = mc^2  
\]

---

12) Citations & Bibliographies

Pandoc can handle citations if you provide a bibliography file. A reference like [@smith2009] can become \cite{smith2009} or \autocite depending on the style and Pandoc’s command-line options.

---

13) Metadata & Title Blocks

Markdown with a YAML metadata block (e.g., “title: My Title”) can become \title, \author, etc., in LaTeX. Use -s or --standalone to generate a title page and call \maketitle.

---

14) Raw LaTeX

Pandoc passes raw LaTeX through if you’re converting to LaTeX or PDF. For example:

\newpage

remains \newpage in the output.
