copy visible text with some lines hidden with hide-lines

copy visible text with some lines hidden with hide-lines

[jdzhang]

I need looking at large (10s of MB) log files regularly. I use hide-
lines to filter out the lines I don't care. However, I was able to
figure out how to copy only the text being displayed. Any suggestions
are welcome.

Thanks.

You could try using `flush-lines' instead, it removes the lines (don't
save the buffer though, then they will be gone).

One thing I've done in the past was to use C-M-! and run a grep command 
which will give me the lines I want (and not too much cruft). Then you 
get a temporary buffer, with which you can't accidentally blat your log 
file by saving (so you needn't be scared of deleting lots more stuff) and 
which is hopefully small enough the Emacs won't get upset about buffer 
size.

If it's a regular job, I suspect one could write a short elisp function 
to get the relevant bits in this way, and maybe rename the buffer to 
something more informative than the standard thing with ** in it.

I think you meant `M-!'.  Have you tried `M-x occur'?

M-x occur works great. Thanks.

Jason.

Oops you're right. And no I hadn't tried M-x occur, but I have now thanks!
