NAME
spix - Compile a .tex file, executing commands that are set inside the file itself.
SYNOPSIS
spix [--version] [-h] [-n] file
DESCRIPTION
spix parses a .tex file to find lines starting with %$ (before the preambule). Those lines are shell
commands that are executed by spix.
Commands are executed as-is, excepted that:
- command are run from the directory of the file given in argument;
- shell variables $texname and $basename are set to the name of the tex file (respectively with
and without the .tex extension).
OPTIONS
-n, --dry-run
Print the commands that would be executed, but do not execute them.
-h, --help
Print help, and exit.
--version
Print version, and exit.
EXAMPLES
Let foo.tex be the following file.
% Compile this file twice with lualatex.
%$ lualatex foo.tex
%$ lualatex foo.tex
\documentclass{article}
\begin{document}
Hello, world!
\end{document}
When running spix on this file, it is compiled twice using lualatex(1) (as written in lines 2 and 3 of
the file).
