Hi,
Grep has nice options to match regular expressions/patterns and highlight
them so that the user can easily see them.
I find a need to have grep output all lines, and just hightlight the matches
as they go by. This is as oppose to it only outputting lines that contain a
match.
This might seem counter intuitive, but I don't think grep by definition is
for filtering lines; instead, it is for finding patterns in files/streams. So,
simply highlighting the matches is a valid thing for grep to do.
Note that grep already has options to output lines containing matches and
lines not containing matches, and even an option to output lines surrounding a
line containing a match. That latter one can be used as a workaround, if a
large enough number is given for --context.
Please consider adding such an option.
