combine isearch-forward-regexp and query-replace-regexp

[Hans-Christoph Wirth]

I usually fail to construct the correct regexp suitable for
query-replace-regexp at first attempt.  

isearch-forward-regexp does a nice job since it highlights all 
matching positions on the fly.

If I composed the right regexp with isearch-forward-regexp, how
can I supply it as an argument to query-replace-regexp?  M-p does
not help.

In Emacs-CVS, if you hit M-% from isearch, it'll do that for
you automatically.

Thanks.  So I guess there's no solution I you are bound to non-CVS
versions ...

There could be another one, I didn't check: do at least one search with 
the expression you foud might suit your needs. Finish searching and do 
a 'repeat-complex-command' (bound to a few keys). In the mini-buffer 
you'll see your expression, C-a C-k C-g and it should be in your 
kill-ring!

one solution is to wait for a future (or past ;-)
emacs release.

Well you can either define this isearch M-% thingy (IIRC it was originally
posted in this newsgroup before being integrated in Emacs-CVS), or you can
go the low-tech route:

   C-s M-p C-k C-g
   M-% C-y

Thanks.  This comes close to what I need.  I made the mistake to leave
the initial isearch with C-g.  When I leave it with RET, the contents
gets stored in the ring buffer, and can be invoked with M-p then.
