So I'm (finally) writing a book, and using groff -mom macros
for typesetting. Wanted to run what I have so far through
style(1) and diction(1), which on Linux requires one to
run the input through deroff(1) first.

Linux doesn't seem to have deroff.

So, here is my q&d solution:

$ cat mini_deroff.pl
#!/usr/bin/perl

%roffchars = ('.',1,' ',1,"\\",1);

while(<>)
{
if(/^\.PP/) { print "\n"; }
next if (exists($roffchars{substr($_,0,1)}));
print;
}
exit 0;

Constructive comments appreciated.

BTW, if there's interest in the document processing, I have
a Makefile that eases the pain of processing, including
a "make look" rule that gens the pdf and views it.

Also, if anyone knows where there is source for a working
Linux deroff(1), would very much appreciate the pointer.
So far I found the OpenBSD one, but it seems to rely on
a lot of preprocessor macros that Linux doesn't have.

Finally, one last look on Google, and I found a version
of deroff for Debian... but it seems to be dated 1996, and doesn't
grok -mom macros. (It is, however, written in lex, which
might be an opportunity for me to learn that lingo and
fix it...)

pandoc -f man -t plain «infile» >«outfile»

works for man pages, anyway.

Never used it, but GNU roff mentions in one of its files (MORE.STUFF) a
deroff by Michael Haardt at

http://www.moria.de/~michael/deroff/

(Timestamps are from 2003 and 2004?)

Besides one for Debian by David Frey (which, I suppose, is the one you
found?)

Does the moria.de one support any of these "mom" macros?

Maybe because it is not needed with GNU groff because groff has
-T ascii or -T utf8 (depending on which you need) to perform a
similar function (remove roff declarations, output plain text).

I never heard of that procedure. I heard of Latex and Tex. Or LyX.

(facepalm)

That works. Thank you.

(However, I did spend a productive evening last night learning
flex. :) )

Hello. I tried it, and still found macro text in the output.

Rich suggested using groff with -Tascii or -Tutf8, which of course
does the trick. (It was a "facepalm" moment for me.)

(I actually kind of feel bad for the author of deroff-2.0: the
scanner appears to be hand-written...)
