# Script for command output colorization
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#
# @(#) [MB] cr_hl_generic Version 1.12 du 15/11/08 -
#
# This script calls the original programme with all the arguments
# it received, and pipes it to "hl" using its name as the "hl"
# configuration.
#
# In case the user doesn't want the output of the command to
# be colorized, the following syntax must be used :
# USE_HL=no cmd [args ...]
#
OUT=/tmp/OUT.$$
ERR=/tmp/ERR.$$
mknod $OUT p
mknod $ERR p
case "$USE_HL" in
n|N|no|NO|0) USE_HL="no"
;;
esac
progname="$(basename $0)"
pathname="$(type -p "$progname")"
dirname="$(dirname "$pathname")"
PATH="$(echo "$PATH" | sed "s|^$dirname:||;s|:$dirname:|:|g")"
export PATH
if [ "$WHICH" = 1 ]; then
type "$progname"
exit 1

if [ "$USE_HL" = "no" ]; then
# No colorization
# ~~~~~~~~~~~~~~~

# Default behaviour : colorization
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
hl -u --"$progname" < "$ERR" & hl --"$progname" < "$OUT" & \
"$progname" "$@" > "$OUT" 2> "$ERR"
