convention for marking LaTeX in programming comments?

Question

Is there a convention for marking the beginning of LaTeX-based material placed inside the comments of (say) a C++ or Python program? Or does one simply jump into LaTeX syntax?

Answer 1

In doxygen the convention is to explain TeX environments with \f.

As doxygen documentation goes in comments, you might call this convention for comments, though it is more convention for in-code documentation.
