Now it works with pcw! Very much like lchat.
Put this in pcw_win.sh:
exec dvtm-ii "$CPATH"
and here is the script, which I named dvtm-ii
#!/bin/sh
set -u
trap cleanup INT TERM QUIT
cleanup() { kill $!; } # make st end when this script does
[ -d "$1" -a -r "$1"/out -a -p "$1"/in ] || exit 1
cmd_fifo=$(mktemp -u) || exit 1
mkfifo "$cmd_fifo" || exit 1
title="$(basename $(dirname "$1"))/$(basename "$1")"
st -e dvtm -M -h 10000 -t "$title" -c "$cmd_fifo" "exec nano -nw \"$1/in\""
"exec tail -n +0 -f \"$1\"/out" &
delay="0.09" # dvtm crashes unless pause at leat 0.07 seconds
# I had to customize dvtm to allow these commands to the command fifo, and it
# was very easy to do so. They are based on the keyboard commands. If you
# haven't customized dvtm, you can just comment out this next paragraph
{
for cmd in b j l l l l l l; do
sleep "$delay"
echo "$cmd"
done
} >"$cmd_fifo"
wait # wait for st
