The simple solution is to use the uppercase name of a register, which appends to the register, rather than the lower case version, which replaces. For example, the A register is identical to the a register, but what you put into A adds to a, instead of replacing it. So, you want: :g/foobie bletch/y A After this, register a will contain every line that has foobie bletch in it. However, it also contains whatever was in it previously, so make sure the register you use is empty first. The uppercase registers are really useful for moving arbitrary chunks of code to a combined destination. Find the first set of lines you want to move and delete them into a lower-case register, e.g. r5dd. Then, go and find the other lines you want and use the upper-case register, e.g. R32dd. Finally, go to your destination and paste either register, e.g. rp.

For single-line patterns, there is also a trick you can use to write the matches directly to the file. I think it is: :g/pattern/.w! file -- Hari __ Do You Yahoo!? Tired of spam? Yahoo!

What about (untested)
:s/foo\_.{-}bar/\=(submatch(0) . nr2char(min([0, setreg(@,
submatch(0), c)])))
- execute it with the cursor on the line where the match starts
- all on one line
- the part after the dot is supposed to append the empty string to the
replace by text while setting the unnamed register to the matched text
To put it into a separate document then:
:new
:0put
:wq
Best regards,
Tony.

Working command is: let @a='' clear the register :silent! g/multi-line-pattern/exe normal v//e\n\Ay This accumulates multi-lines containing multiline patterns into register A. Explanation: v//e turn current pattern into visual selection Ay append visual selection to register A For best results, make pattern match up to and including the trailing \n of the last line of the mathing line (append .*\n if needed). Otherwise, last substring of the previous match will merge with first substring of next match in A. Yakov

I don't see any Vim primitives to work with multi-line matches. I think
the searchpos() function should be extended to return the [line, col] of
the end of the match as well. May be I am missing something, but in the
absence of primitives, you can probably write a function which will
try to guess what the matching lines are, something like this (only
partly tested):
function! FindMatchingRange()
function! FindMatchingLines()
let start = line('.')
let text = ''
for end in range(start, line('$'))
let text = text.\n.getline(end)
if text =~ @/
return start.','.end
return text
endif
endfor
return ''
endfunction
You can use this either use it with :g command, or another function
:let matches=[]
:g/pattern/call add(matches, FindMatchingLines())
you can paste the matches in a new buffer as:
:call append('$', matches)
Read the help on |string-match| for limitations.
