Automatic display of X-Face
Hello,
For those who'd like to display the X-Face of a message
automatically, here's a dirty way to do it:
--- xfacefilter.sh ---
#!/bin/sh
###################################################################
# display_filter for mutt #
# to automatically show X-Faces in pager at end of message #
# #
# Required programs: #
# formail, uncompface, icontopbm, image2ascii #
# #
# Usage examples muttrc: #
# unignore X-Face #
# set display_filter=xfacefilter.sh #
## in case you want to write tmpfile only if needed: #
# message-hook ~A "set display_filter=''" #
# message-hook "~h ^X-Face:." "set display_filter=xfacefilter.sh" #
## at end of filter chain: #
# set display_filter="sed -f myfilter.sed|xfacefilter.sh" #
###################################################################
set -e
self=${0##*/}
CLEANUP()
{
rm -f "$tf"
}
trap "CLEANUP" 0 1 2 3 15
tf=`mktemp -t ${self}.XXXXXXXXXX` || exit 1
tee "$tf"
xface=`formail -zcx X-Face: <"$tf"`
if [ -n "$xface" ]
then
printf "\n\n===== X-Face displayed by $self =====\n\n"
echo "$xface" | {
echo '/* Width=48, Height=48 */'
uncompface
} |
icontopbm |
image2ascii
fi
exit $?
--- end ---
If you don't like ascii-graphics in the pager removing the
printf... line and using "xli -fork stdin" or something similar
instead of image2ascii should work too, but I wanted to keep the
example small.
In python I could think of ways to avoid the tempfile creation,
but this is faster.
