py2tex

Use Python within your latex files.

Within a LaTeX file, encapsulate python code between 🐍 tags. Anything you print will be inserted into the resulting LaTeX document.

Example

Here's what a .pytex file might look like:

\documentclass{article}
\begin{document}

🐍
print(R'Python \textrightarrow{} \LaTeX{}!')
🐍

\end{document}

The corresponding LaTeX for this would be:

\documentclass{article}
\begin{document}

Python \textrightarrow{} \LaTeX{}!


\end{document}

How to use it: Standalone

If you compile your latex documents manually using pdflatex or some other LaTeX engine, simple run the following command beforehand:

$ py2tex infile.pytex outfile.tex

How to use it: latexmk

If you use latexmk, perform the following steps to add py2tex as a custom dependency:

1. Place py2tex.py into your project's root directory
2. Create a latexmkrc file (if you don't already have one) and add a custom dependency to the end of it like this:

add_cus_dep('pytex','tex',0,'py2tex');
sub py2tex {
  system("./py2tex.py \"$_[0].pytex\" \"$_[0].tex\"");
}

That's it! Now latexmk will use the py2tex.py to convert your .py2tex files to .tex files. Here are some general guidelines for how latexmk decides to run the dependency:

• The .pytex and corresponding .tex file must have the same basename (e.g., main.pytex -> main.tex).
• The .pytex must have a system modiciation date earlier than the .tex file for latexmk to trigger the custom dependency.

If you want your root latex file (latexmk's default_files variable) to be a .pytex file perform the following steps (assuming your root is named main.pytex):

1. Add the following line to your latexmkrc:

@default_files = ("main.tex");

2. Ensure that main.tex exists and has a system modification date older than your main.pytex file.

Styling

If you use the Sublime Text editor, you might find the pytex.sublime-syntax file helpful. It provides syntax highlighting for pytex files (standard LaTeX outside 🐍 tags, standard python within 🐍 tags). Import it using "Tools -> Developer -> New Syntax".

Additional Information

This utility does not recognize escaped 🐍 tags. If you must use 🐍 in your python or LaTeX code, consider using its unicode encoding instead (U+1F40D).
