PyLaTeX is a Python library for creating LaTeX files. The goal of this library is being an easy, but extensible interface between Python and LaTeX.
The library contains some basic features I have had the need for so far. Currently those are:
- Document generation and compilation
- Section, table, math and package classes
- A matrix class that can compile NumPy ndarrays and matrices to LaTeX
- An escape function
- Bold and italic functions
- Every class has a dump method, which writes the output to a filepointer
Everything else you want you can still add to the document by adding LaTeX formatted strings instead of classes or regular strings.
- Python 3.3 (Python 3.x might work as well)
- pdflatex (only if you want to compile the tex file)
- NumPy (only if you want to convert it's matrixes)
- ordered-set

I will keep adding functionality I need to this library, an interface for graphics and math will probably be added in a future version.
If you add a feature yourself, or fix a bug, please send a pull request.
You can submit issues, but it will not be my priority to fix them. My job and education are a bit higher on the priority list.
This library is being developed for Python 3.3. It currently doesn't work for Python 2.7, but it's mostly syntax and import changes that break it for 2.7. It is also only tested on Linux, so it might not work on any different platforms.
I have no intention of testing on any different platforms or with different Python versions. I also don't have the intention to write fixes for platform or environment specific bugs, but pull requests that fix those are always welcome.
