I am building a mathematical software with PyQt, and I would like to provide the users with a result in a file written in LaTex and also the compiled version of it in PDF. However, I can't find a way to do so. All solutions I've seen require me to install a compiler locally.
I cannot expect the users to install a compiler in their computers once they have executable version of the software. That is why I am looking for a solution that does not requires my system to have it.
This question is not about displaying mathematical typesetting in Qt, but about generating a document report in LaTex and also a easy way to visualize it in PDF.
LaTeX uses a complex typesetting engine. That's why it's used - a professional grade typesetting engine. Something needs to do that typesetting. One way is to "just" reimplement that engine in python yourself. Maybe you only need a subset of LaTeX. Maybe you can convert the LaTeX syntax into something more simple like markdown and render that to PDF.
For math typesetting, katex as mentioned in a comment might be an option for you.
Maybe your use case allows you to make it a client server software architecture and do the compiling on a server. LaTeX.Online has a docker container to create the API
Others mentioned the traditional way, just package the dependency.

That is why you should install it with the rest of your program.
MiKTeX allows for a silent installation.
TeX live has similar options
