On the math SE site, one can render LaTeX by placing it between two Dollar signs, e.g. $a \in X$. It's also possible to type a literal Dollar sign by escaping with a backslash. What are the options available to me if I want to implement something similar? I'm guessing there must be a library that handles the difficult parts for me, but I haven't been able to find one! For example, in the string Andrew Wiles proved that if $a^n+b^n=c^n$ for $a,b,c \in N$, then $n=1$, only the things between the Dollar signs should be rendered as LaTeX.
Note: it's not so much the rendering part that I'm concerned with, as I know there's a multitude of libraries to do that, I just don't know how to actually extract what I need to render. Although if there is a library that both extracts and renders then I'm all ears.
