Re: how to repeat the last :[range]g with the same range?

hi Tim：
I tested it , with that line in my vimrc, 
a ":MyGrep" command still doesn't pick up the "previous" range I used in a g:// and still seems search the whole buffer.
maybe I'm not following, but currently I'm just using that "qaq" + "[range]g//y A" method and then manually paste reg a into next tab.
thanks for your help and time spent on it anyway!

regards

you finally are satisfied with the info you grabbed, then

2) with a new defined cmd like this:
"command! MyGrep execute 'normal! 0"ay0' | execute 'g//y A' | tabnew |
enew | setlocal bt=nofile | put! a | nohls
now with :MyGrep, ideally if there is no *range*, will got last matches
and put in a neighboring tab,

First, that's a hideous command definition (to the degree I went out to the wiki and changed it to be more legible).  If you're going to use normal mode, the canonical way to clear a register is to use "qaq" to clear register "a".  I prefer the explicit nature of setting it in Ex with ":let @a=''".

I'd be tempted to make use of the ability to pass ranges to a command with something like

 command! -range=% MyGrep let @a='' | execute '<line1>,<line2>g//y A' | tabnew | enew | setlocal bt=nofile | put! a | nohls

which you can read about at

  :help command-range
  :help <line1>

3) repeat 1) on this new buffer(maybe with different range and pattern)

I'd say it's highly unlikely that one would *want* the same range in this secondary buffer, since it's already been winnowed down to the specified range by this point.  However, the same pattern makes sense and can be done using the blank pattern as above.
