latex-online VS symengine

I use Overleaf for everything Latex/Beamer related, and backup my projects onto Github. There used to be a website (https://latexonline.cc/) which would generate a static link for you that would compile a PDF from a specified github repository. It was a great way to share developing presentations and reports.

Read the doc https://github.com/aslushnikov/latex-online/blob/master/README.md

Latex online use a script that is available to download and use offline, see the doc here : https://github.com/aslushnikov/latex-online#installation

SymEngine will do this: https://github.com/symengine/symengine

If you need programmability or interoperability, Sympy is way nicer. If you just want an interactive symbolic calculator, Maxima is fine but sometimes quirky (has odd conventions due mainly to its age). As heisig points out, Maxima can be quite a bit faster (but I run into slow things with it too). Using Maxima via Sage is in some ways the best of both worlds.

Context: I'm making a application for robotics calculations, making symbolic calculations using (symengine), and at some point I would like to be able to see the steps of these calculations, symengine has a function that returns the latex code do the elements you want. So I was trying to find a library or something of sorts to render that text into an image, I'm using Dear IMGUI in the docking branch to make a simple UI where I would like to display these equations. I know it might not even exists but I would like to give it a try. I found KLateXFormula, which depends on Qt as far as I understood, so I would like to avoid that if possible, I also studied a bit about the TeXStudio repo and found they use Qt to render previews. I also tried to understand the miktex repo searching for a function that I could use, but I barely understood the structure of the repo. I'm getting frustraded. I also found approaches where people would call latex executables to parse latex to DVI(Or something like this) but I would also like to avoid this approaches if possible.

- Might there be any way to leverage the work of https://github.com/symengine/symengine ? I assume a straight-up language binding to symengine might be a completely separate project, but possibly for some specific features symengine, maybe... (It is a pity they chose c++ and not rust to implement symengine in. In the end, the main target seems python/sympy here and not c++.)
