[Tex/LaTex] Convert LaTeX to SymPy format

luatexpython

I'm trying to convert LaTeX to SymPy understandable format and I feel it's hard to comply all conditions. So Im wondering if you can suggest any tools, free or paid, that will be great.

What I'm looking for is:

\frac{1}{3x^{2} + 13x - 10} to (1)/((3*x)**2+13*x-10)
\lim_{x\to a}\frac{x}{y} to limit(x/y,x,a)

Here's a parser that does the job for a big subset of Latex:

[Tex/LaTex] Why is LuaLaTeX so slow and is there anything I can do about it

Running some tests and looking at the output of the process monitor I found that on windows with miktex the "feature" of fontspec to load default settings from a file with the ending .fontspec is slowing down the font search considerably as miktex is looking everywhere for the files. Disabling the feature meant for me that this document needed only around 2.5 seconds instead of 12. In texlive the time gain was 3 seconds instead of 4.6.

\documentclass{article}
\usepackage{fontspec}
\ExplSyntaxOn
\cs_set:Nn \__fontspec_load_external_fontoptions:Nn
 {}
\ExplSyntaxOff
\usepackage{libertine}


\begin{document}
abc
\end{document}

Edit

In the case of miktex there is imho a bug in the file search: unlike pdflatex or xelatex lualatex doesn't rely on the FNDB but starts a real file search in the texmf tree. I made a bug report: https://sourceforge.net/p/miktex/bugs/2356/. In the case of texlive I still have to test if I can improve the compilation time by forcing texlive to use only the ls-R-files.

Edit 2

One can improve the compilation time in texlive by creating more ls-R-files (at least on my system with quite a lot of local roots ...), but the effect is not so dramatic as the large texmf-trees like texmf-dist already uses only the ls-R.

Edit 3

Miktex has added a patch to luatex. With todays update it no longers does a slow disk search if a file is not found. The compilation time of a document which loads e.g. libertine dropped from 12 to 3 seconds on my PC ;-).
