This is really needed 2025-2026 and onwards, don't expect designers to code their assignments of mathematicians and physicists that can't design. Please for the love of creation do something about this, the AI of today and tomorrow are already using it and their inability to produce XML based Math and also the copy pasting it is not cool, they already work with .tex (LaTeX) so what are we waiting for? It has been years and years, Decades even that people need this kind of solution.

You guys should take a look at this:
https://www.reddit.com/r/indesign/comments/13aqeex/latex_integration/

It allows you to input pdf files containing equations from a LaTeX code.

4 years on, and no real hint that this will ever happen.

There are LOTS of open source tools to model LaTeX with, and even a readily-available design spec for things like mathematical outputs.

There are a couple of online tools that generate images from LaTeX (.png and .jpg) but that's really adding an extra 5-6 steps that could be bypassed if we had this.

Its really difficult to work with equations in InDesign. Latex interface would be a wonderful tool and it will make Indesign more powerful. If matah interface is not possible then atleast there should be a provision to write Latex code in Indesign which will convert it to equation.

This seems like a very easy thing to do. We could place a LaTeX box and then enter in LaTeX code which InDesign can then process into an output format.

Even if Id just integrated to a separate LaTeX compiler (e.g. MiKTeX) to generate a PDF image and read in the resulting file as an object that would be something.

Now it canbe done by a JavaScript tool -- In-TeX/LaTeX :

It should be possible to create an import on InDesign accepting some output of Latex (special compiler)
