pp(1)
is a shell preprocessor developed by our own user adi.
It allows one to embed shell into any text file between instances of the token #!
. This powerful
tool allows the dynamic generation of static pages using standard bourne shell.
For example:
<!doctype html>
<title>pp(1) example</title>
<ul>
#!
i=1
while test $i -le 10
do
if test $((i % 2)) -eq 0
then
#!
<li class=even>$i</li>
#!
else
#!
<li class=odd>$i</li>
#!
fi
i=$((i + 1))
done
#!
</ul>
Will output, per the manual page:
<!doctype html>
<title>pp(1) example</title>
<ul>
<li class=odd>1</li>
<li class=even>2</li>
<li class=odd>3</li>
<li class=even>4</li>
<li class=odd>5</li>
<li class=even>6</li>
<li class=odd>7</li>
<li class=even>8</li>
<li class=odd>9</li>
<li class=even>10</li>
</ul>
The manpage includes more information on advanced features, such as piping stdin
and debugging.
