I posted a note in the newsgroup gnu.emacs.lisp.manual regarding splitting
up the 500+ page Emacs Lisp reference manual. In that note I included the
following short shell script and noted that I had made a one line change to
dviselect (authored by Chris Torek - it's a great program, Chris) to cause
it to exit with a status of 1 if no pages of output were generated.
I've had several requests for the modified dviselect, some from people who
seemed to not be able to get ahold of the original. I got dviselect from the
utilities subdirectory of the texx2.8 distribution and repackaged it
somewhat so that it is a standalone piece of software. It will be posted to
alt.sources (in six parts). If you can't get it from there, let me know and
I'll arrange to mail them pieces to you.
#!/bin/sh
NUM=$1
FIRST=1
LAST=$NUM
DOTSPERLINE=60
DOTS=0
dviselect -s -i $2 -o $2.$FIRST-$LAST $FIRST:$LAST
while [ $? = "0" ] ; do
# a little feedback for the user
echo -n "." ; DOTS=`expr $DOTS + 1`
if [ $DOTS -ge $DOTSPERLINE ] ; then
echo ""
DOTS=0
fi
# select the pages
FIRST=`expr $FIRST + $NUM`
LAST=`expr $LAST + $NUM`
dviselect -s -i $2 -o $2.$FIRST-$LAST $FIRST:$LAST
done
if [ $DOTS -gt 0 ] ; then
echo ""
fi
rm -f $2.$FIRST-$LAST
exit 0
