When using Vim is there a way that :grep or :vimgrep will color the patterns returned to the buffer?
:grep
:vimgrep
If you search for the pattern after you've :vimgrep'd it, Vim will highlight it. Just edit the :vimgrep pattern files into :g/pattern/.
:vimgrep pattern files
:g/pattern/
For a richer solution, try this script.
