Narrow buffer to the results of an isearch?

Narrow buffer to the results of an isearch?

[Ryan Newton]

Maybe this is impossible, I certainly haven't found anything on it yet.

What I want is to mask the current buffer to all lines matching an  
search.  Unfortunately I don't know if narrow-to-region can be used  
for this, because the region is defined as a continuous area of text  
between the mark and the point.

Has anyone hacked up support for discontinuous regions?  Or some  
other way that I can filter the buffer to only my lines of interest?

Depending on what do you want to do with the buffer, M-x occur might
work for you. And there is also an outline mode which you could look
into.

You can get a lot more done with a kind word and a gun than with
a kind word alone.

M-x occur

Thanks, M-x occur is pretty good.  I can see them all together, and  
editing them isn't too hard.

B.T. Raven, I would hesitate to try to sed-out a separate buffer for  
fear of it being difficult to reinsert.  (But by just including line  
numbers in the sed output and reinserting at those line numbers,  
maybe it wouldn't be so bad...)

Thanks all,

There is a page on http://www.emacswiki.org/ about occur and moccur that 
I believe could be interesting. If I remember correctly there is even a 
way to edit the results from an moccur search. Quite nice!

Since the emacs buffer is only a copy of the visited file, you could
shell out to the operating system, run 'sed' (Unix stream editor) on the
file, pipe the output to temp, and then read temp into another buffer,
or even insert it into or append it to the original buffer. It might
even be possible to automate this entire process with a little help from
elisp and your friends. Rather than isearch, you will probably want to
use the more powerful search regexp.

Maybe this helps:

  "Hide lines that don't match the specified regexp." ...
