- Why can't TeX.SE compile my TeX code? 3 answers
I know that a lot of users asked for a way to insert support for LaTeX code (or at least equations) like math.stackexchange and other SE sites. All of them received as comment/answer that this site is about (La)TeX, so all of the user need to see the actual code and not a result that can change based on different factors. In fact, I'm not asking to a way to insert (La)TeX code like other sites, I'm asking why we could not have a snippet, like the one on stackoverflow for HTML, JS and CSS, that has TeX Live on it.
Of course there will be cases when this is not enough, in these cases one could simply use the classical way of asking questions, i.e. post the TeX code and the resulting pdf.
Note that I'm not sure that this wasn't asked before, but I googled it and the only question that I found were about the possibility to insert (La)TeX code like math.stackexchange, not with a snippet.
