On a brute-forcier note, when I was doing a lot more troff, I wrote a
command that ran input through *ALL* the preprocessors I might need. Even
on 70's processors, it was fast enough, and msde my life a tiny bit
better. -- jpl

This proposal reminds me of Paul Glick’s lp command.
It took whatever
file you gave it, and processed
it as necessary for whatever printer you chose. It was very useful,
simple AI.

I can imagine a simple perl (or python or whatever) script that would
run through
groff input, determine which preprocessors are actually needed,
and set up a pipeline to run through (only) the needed preprocessors in the
proper order. I wouldn't have to tell groff what preprocessors I think are
needed, and groff wouldn't have to change (although my script would) when
another preprocessor comes into existence. Modern processors are fast
enough, and groff input small enough, that the "extra" pass wouldn't be
burdensome. And it would take the burden off me to remember exactly which
preprocessors are essential. -- jpl
