[luatex] LuaTeX precompilation

[David Carlisle]

> To have it wait for say a HUP signal (or USR1) you could just use
\directlua{} to require the luaposix module

rather than a lua module handling posix signals you can tell tex to pause,
then send it a newline to stdin to continue


\documentclass{article}
\usepackage{tikz,pstricks,siunitx,unicode-math}% any other big packages
\begin{document}

\pausing=1
\pausing=0
\input{story}
\end{document}


will pause allowing you to make a new file story.tex if you don't like the
original story then will continue to the end if sent a newline, works of
course for any tex system, not just luatex,
