I do roughly the same, though I use a wrapper script that lets me choose an
inline (sixel) or external viewer. Sometimes I want to view the image while
walking mutt on to another task, and in that case the wrapper script
handles the lifecycle of the temporary file thus needed.
mailcap:
# -i or -e, or neither for a choice
image/*; mutt-view-image -i %s
mutt-view-image:
#!/bin/sh
case "$1" in
-i) mode=inline; shift;;
-e) mode=external; shift;;
*) : ;;
esac
if [ "$mode" = "" ]; then
normal=$(stty -g)
printf "Do you want to view (i)nline or (e)xternal? "
trap "stty $normal" 1 2 3 15
stty raw -echo
c=$(dd if=/dev/stdin bs=1 count=1 2>/dev/null)
stty $normal
echo
pause=false
case "$c" in
i*) mode=inline;;
e*) mode=external;;
esac
fi
if [ "$mode" = "inline" ]; then
view="img2sixel %s 2>/dev/null"
pause=true
elif [ "$mode" = "external" ]; then
view="xopen %s; sleep 10"
fi
xopen () {
# External open
d=$(dirname "$1")
f=$(basename "$1")
fn="$d/async_$f"
ln "$1" "$fn"
at now + 5 minutes <<EOF
rm "$fn" >/dev/null 2>&1
EOF
# This opens on Linux or MacOS
(xdg-open "$fn" || open "$fn") 2>/dev/null
}
cmd=$(printf "$view" "$1")
eval $cmd
if $pause; then
restore=$(stty -g)
trap "stty $restore" 1 2 3 15
echo
echo "Press any key to continue..."
stty raw -echo
dd if=/dev/stdin bs=1 count=1 of=/dev/null
stty $restore
fi
