Python-LaTeX

Python-LaTeX is a program written in python that process .ptx files with latex code and, between this, python code embedded with '««' '»»' delimiters. Python-LaTeX output latex file.

Dependences

• TeX Live 2013 - $ sudo apt-get install texlive-full
• Python3 - $ sudo apt-get install python3
• Sympy

$ git clone git://github.com/sympy/sympy.git
$ cd sympy
$ sudo python3 setup.py install

• SciPy - $ sudo apt-get install python3-scipy
• NumPy - $ sudo apt-get install python3-numpy

Setup

Add two lines to .bashrc file.

1. Declare system variable. export PYTHON_LATEX=[/path/to/Python-LaTex]
2. Add to PATH variable. export PATH="$PATH:$PYTHON_LATEX/bin"

Basic usage

• .ptx file to .ltx file. py2tex [.ptx file]
• .ptx file to .pdf file. py2pdf [.ptx file]
• .ptx file to .pdf files with and without solutions. py2pdf -s [.ptx file]

Usage without scripts (for example on Windows)

• .ptx file to .ltx file. python3 /path/to/Python-Latex/python/pytex.py [.ptx file]

Basic example

.ptx file: sample.ptx

\begin{equation}
7! = ««factorial(7)»»
\end{equation}

Command line

$ python3 /path/to/Python-Latex/python/pytex.py sample.ptx 
% Python-Sympy -> LaTeX success.

Output file: sample.ltx

[... Latex preamble ...]

\begin{document}

\begin{equation}
7! = 5040
\end{equation}
