I would like to be able to make sure that in the file (.tex) the entire preamble is not seen, in the sense that it is there and actually works, but not seen, so that it preserves all the lines of code that the latter is reserve. for example:
\documentclass{book}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage{sidenotes}
\usepackage[italian]{babel}
\usepackage{url}
I would like all these packages to work, but I only see in the compile file:
\hiddenpart{in this there is everything that is hidden there, which must not be seen but obviously}
\begin{document}
\end{document}
