Abstract

This example shows how to use LuaTeX to run software tools and utilities installed on Overleaf’s servers, including how to capture, and then typeset, text that would normally be displayed in a terminal window.

\documentclass{article}

\begin{document}
\directlua{
function runcommand(cmd)
  local fout = assert(io.popen(cmd, 'r'))
  local str = assert(fout:read('*a'))
  fout:close()
  return str
end

local sout=runcommand("dvisvgm --help")
local marg = assert(io.open("command.txt","w"))
marg:write(sout)
marg:flush()
marg:close()
}
\verbatiminput{command.txt}
