I have a set of scripts and macro files which highlight differences against cvs and hg. They could be adapted to your requirements.
This script invokes nc and checks for differences against the version control system. It accepts arguments of the form file:line which is output by grep -n
#! /bin/ksh
# name: nb
for i in $*;
do
file_name=`echo $i | awk -v FS=: '{ print $1 }' -`
line_number=`echo $i | awk -v FS=: '{ print $2 }' -`
if [ -d $file_name ]
then
echo $file_name "is a directory"
else
diff=`$NEDIT_HOME/get-cvs-diff $file_name`
# echo $diff
if [ -z "$line_number" ]
then
param=$diff
else
param=$diff"+l_"$line_number"_0"
fi
if [ ! -z "$param" ]
then
cmd="-do mark_diff(\"$param\")"
else
cmd=
fi
# echo "["$cmd"]"
$NEDIT_HOME/nc $cmd $file_name
fi
done
This script outputs encoded diff information:
#! /bin/ksh
# name: get-cvs-diff
dir=`echo $1 | awk -v FS=/ '{ for(i=1;i<NF;i++) printf("%s/",$i) }' -`
cvsdir=$dir"CVS"
if [ -d $cvsdir ]
then
cvs status $1 | egrep "Needs Merge|Locally Modified" > /dev/null
if [ $? -eq 0 ]
then
MACHINE_KIND=`uname -s`
if [ "$MACHINE_KIND"=="OSF1" ]
then
tmpfile="/tmp/np.tempfile"
else
tmpfile=`mktemp /tmp/np.XXXXXX`
fi
awk -f $NEDIT_HOME/line-starts.awk $1 > $tmpfile
cvs diff $1 | egrep -v "[\<\>\-]" | egrep "^[0-9].*" >> $tmpfile
awk -f $NEDIT_HOME/analyse-change.awk $tmpfile
rm -f $tmpfile
fi
else
if [ -x `which hg` ]
then
hg root > /dev/null
if [ $? -eq 0 ]
then
MACHINE_KIND=`uname -s`
if [ "$MACHINE_KIND"=="OSF1" ]
then
tmpfile="/tmp/np.tempfile"
else
tmpfile=`mktemp /tmp/np.XXXXXX`
fi
awk -f $NEDIT_HOME/line-starts.awk $1 > $tmpfile
hg diff $1 >> $tmpfile
awk -f $NEDIT_HOME/analyse-change-hg.awk $tmpfile
# cat $tmpfile
rm -f $tmpfile
fi
fi

This is line-starts.awk. Highlighting works per character so you need to associate lines with character indexes.
BEGIN {
total = 0
}
{
printf("line-start,%s,%s\n",FNR,total)
total = total + length + 1
}
END {
printf("line-start,%s,%s\n",FNR+1,total)
}
This is analyse-change.awk. It checks for diffs against cvs and outputs
stuff which is eaten by an nedit macro.
BEGIN {
FS=","
}
/line-start[,][0-9]*[,][0-9]*/ {
# print $2 " " $3
line_starts[$2]=$3
}
/[0-9]*[,][0-9]*[c][0-9]*[,][0-9]*/ {
n = split($2,range,"c")
printf ("+c_%d_%d",line_starts[range[2]],line_starts[$3 + 1])
}
#980,984c988
/^[0-9]*[,][0-9]*[c][0-9]*$/ {
n = split($2,range,"c")
printf ("+c_%d_%d",line_starts[range[2]],line_starts[range[2]+1])
}
#1676a1692
/^[0-9]*[a][0-9]*$/ {
n = split($1,range,"a")
printf ("+a_%d_%d",line_starts[range[2]],line_starts[range[2]+1])
}
#193a194,197
/^[0-9]*[a][0-9]*[,][0-9]*$/ {
n = split($1,range,"a")
printf ("+a_%d_%d",line_starts[range[2]],line_starts[$2 + 1])
}
#846c853,867
/^[0-9]*[c][0-9]*[,][0-9]*$/ {
n = split($1,range,"c")
printf ("+c_%d_%d",line_starts[range[2]],line_starts[$2 + 1])
}
#457c504
/^[0-9]*[c][0-9]*$/ {
n = split($1,range,"c")
printf ("+c_%d_%d",line_starts[range[2]],line_starts[range[2]+1])
}
function print_count()
{
if(inplus == 1)
{
if(minuslines > 0)
{
printf
("+c_%d_%d",line_starts[plusstart+1],line_starts[plusstart+minuslines+1])
minuslines = 0 }
printf
("+a_%d_%d",line_starts[plusstart+minuslines+1],line_starts[plusstart+pluslines+1])
inplus = 0 }
}
This is the version for hg
BEGIN {
FS=","
}
/line-start[,][0-9]*[,][0-9]*/ {
# print $2 " " $3
line_starts[$2]=$3
count = 0
next

This is highlight.nm. It defines the mark_diff function which parses the output of the above scripts and puts backlight into the window.

rangeset_add(cddr,details[1],details[2])

Clearly I had a lot more time on my hands when I wrote this stuff.
