Convert MediaWiki to LaTeX

Why Convert MediaWiki to LaTeX?

Converting MediaWiki markup to LaTeX bridges the gap between collaborative wiki content creation and professional academic publishing. Wikipedia and wiki-based documentation often contain valuable research, encyclopedic knowledge, and technical content that would benefit from LaTeX's superior typesetting capabilities when published in academic papers, textbooks, or formal reports.

One of the strongest connections between MediaWiki and LaTeX is mathematical notation. MediaWiki already uses LaTeX syntax for mathematical formulas through its <math> tags. When converting to LaTeX, these formulas are preserved in their native format, requiring no transformation at all. This means equations like E=mc^2, integrals, matrices, and complex notation render with LaTeX's world-class mathematical typesetting.

The conversion maps MediaWiki structural elements to their LaTeX equivalents: == headings == become \section commands, wiki formatting becomes \textbf and \textit, wiki tables are converted to tabular environments, ordered lists become enumerate environments, and unordered lists become itemize environments. The result is a compilable LaTeX document that can be processed by pdflatex, XeLaTeX, or LuaLaTeX into publication-quality PDF.

For academics who reference Wikipedia articles or maintain research wikis, this conversion streamlines the process of incorporating wiki content into formal papers. Instead of manually retyping wiki content in LaTeX, the converter produces a clean .tex file with proper document class, packages, and structure. References can be exported to BibTeX format for proper academic citation management.

Key Benefits of Converting MediaWiki to LaTeX:

• Mathematical Excellence: Wiki LaTeX math preserved with perfect typesetting
• Publication Quality: Professional typography for academic papers
• Academic Standard: Output accepted by journals and conferences
• Automatic Numbering: Sections, figures, tables, and equations auto-numbered
• Bibliography Support: Wiki references converted to BibTeX entries
• PDF Generation: Compile to high-quality PDF with any LaTeX engine
• Cross-References: Automatic \label and \ref for internal linking

Practical Examples

Example 1: Scientific Wiki Article

'''Special relativity''' was published by
[[Albert Einstein]] in 1905.

where ''E'' is energy, ''m'' is mass, and
''c'' is the speed of light.

Einstein, A. (1905)

Output LaTeX file (physics.tex):

\documentclass{article}
\usepackage{amsmath, hyperref}

\begin{document}
\section{Special Relativity}

\textbf{Special relativity} was published
by Albert Einstein in 1905.

\subsection{Mass-Energy Equivalence}
The famous equation:
\[ E = mc^2 \]

where \textit{E} is energy, \textit{m}
is mass, and \textit{c} is the speed
of light.

\bibliographystyle{plain}
\end{document}

Example 2: Wiki Table to LaTeX Tabular

Input MediaWiki file (data.mediawiki):

== Experimental Results ==

{| class="wikitable"
|-
! Sample !! Temperature (K) !! Pressure (atm)
|-
| A-001 || 298.15 || 1.00
|-
| A-002 || 373.15 || 2.50
|-
| A-003 || 473.15 || 5.00
|}

''Table 1: Laboratory measurements''

Output LaTeX file (data.tex):

\section{Experimental Results}

\begin{table}[h]
\centering
\begin{tabular}{|l|c|c|}
\hline
\textbf{Sample} & \textbf{Temp (K)}
  & \textbf{Pressure (atm)} \\
\hline
A-001 & 298.15 & 1.00 \\
A-002 & 373.15 & 2.50 \\
A-003 & 473.15 & 5.00 \\
\hline
\end{tabular}
\caption{Laboratory measurements}
\end{table}

Example 3: Research Notes with Citations

Input MediaWiki file (research.mediawiki):

== Machine Learning Overview ==

'''Machine learning''' is a branch of
[[artificial intelligence]].

=== Key Algorithms ===
# Linear Regression
# Decision Trees
# Neural Networks

=== Applications ===
* Natural language processing
* Computer vision
* Recommendation systems

Bishop, C. (2006). ''Pattern
Recognition and Machine Learning''.

Output LaTeX file (research.tex):

\section{Machine Learning Overview}

\textbf{Machine learning} is a branch of
artificial intelligence.

\subsection{Key Algorithms}
\begin{enumerate}
  \item Linear Regression
  \item Decision Trees
  \item Neural Networks
\end{enumerate}

\subsection{Applications}

Frequently Asked Questions (FAQ)

Q: How are MediaWiki math formulas handled in the LaTeX conversion?

A: MediaWiki already uses LaTeX syntax for mathematical formulas inside <math> tags. These formulas are extracted and placed directly into LaTeX math environments (\[ ... \] for display math, $ ... $ for inline math). No transformation of the formula syntax is needed since both formats use identical mathematical notation. This makes MediaWiki-to-LaTeX conversion particularly seamless for scientific content.

Q: Can I compile the output LaTeX file directly?

A: Yes! The output includes the necessary \documentclass declaration, \usepackage commands, and \begin{document}...\end{document} structure. You can compile it directly with pdflatex, xelatex, or lualatex to produce a PDF. For documents with BibTeX references, run the standard latex-bibtex-latex-latex compilation sequence. The file is ready for Overleaf or any local TeX distribution.

Q: How are wiki tables converted to LaTeX?

A: Wiki tables are converted to LaTeX tabular environments within table floats. The column alignment, header row formatting (\textbf for headers, \hline for borders), and cell content are mapped from wiki syntax. Complex tables with merged cells use the multicolumn and multirow packages. The table caption is generated from any description text accompanying the wiki table.

Q: What LaTeX document class is used?

A: The default output uses the \documentclass{article} class, which is suitable for most wiki articles and papers. For longer documents with multiple sections, the report or book class may be more appropriate. You can easily change the document class after conversion. Common packages like amsmath (math), hyperref (links), graphicx (images), and booktabs (professional tables) are included automatically.

Q: How are wiki references converted to LaTeX citations?

A: Wiki <ref> tags are converted to LaTeX \cite commands with corresponding BibTeX entries. The citation data (author, title, year, journal) is extracted from the reference text and formatted as @article, @book, or @misc BibTeX entries in a companion .bib file. The natbib or biblatex package is configured for proper citation formatting in the output document.

Q: Does the conversion handle images from wiki pages?

A: Wiki image references ([[File:image.png]]) are converted to LaTeX \includegraphics commands within figure environments. The image file path is set relative to the document, and you need to ensure the image files are available in the same directory. Caption text and positioning options (center, float) are mapped from the wiki image parameters. The graphicx package handles image scaling and placement.

Q: Can I use the output with Overleaf?

A: Absolutely! The LaTeX output is fully compatible with Overleaf, the popular online LaTeX editor. Simply upload the .tex file (and any associated .bib and image files) to a new Overleaf project and compile. Overleaf provides real-time preview, collaboration features, and automatic compilation. The document will render with professional typographic quality using Overleaf's TeX Live distribution.

Q: How does MediaWiki-to-LaTeX compare to manually rewriting in LaTeX?

A: Automated conversion saves significant time, especially for long documents with many sections, lists, and tables. The converter handles the structural transformation (headings to sections, lists to environments, tables to tabulars) perfectly. Mathematical formulas need no modification since both formats use the same notation. Manual refinement is typically needed only for fine-tuning layout, adding custom preamble options, or adjusting float placement.
