Eeb development -- use the internet to call the shell to compile a latex file?


I have a webpage that displays a latex .tex file. I would like to be able to compile this latex .tex file online.

In order to compile a latex file via the shell one needs to type the following:

> latex onlinefile.tex

this will compile the file and produce two files: and onlinefile.dvi. I would like to be able to compile the onlinefile.tex file by clicking a submit button on my webpage.

How can I achive this?

Write a CGI script that does the job for you. Here's an example just using the some shell script. (Warning do not use it unmodified)
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <title>Calling Latex</title>

    <h1>Calling Latex</h1>

    <form action="cgi/run_latex.cgi" method="post">
      <p> I will call run_latex a dummy </p>
      <input type="submit" value="Do it" />


the run_latex.cgi script:

echo "Content-type: text/html\n\n"
echo "<html>"
echo "  <body>"

echo "<p>I will pretend to call latex<p>"

echo "<p>latex some_file.tex</p>"
echo "</body> </html>"

Now instead of echo "<p> latex...." you call
latex some_file.tex
And then this file gets compiled.
