Scrolling text erases the search highlight

Scrolling text erases the search highlight

[Gabriel TEIXEIRA]

Hello

Always when I do a search in emacs (by typing C-s search-string), emacs 
will highlight all the matching strings, but if I try to scroll the text 
to see the occurrences down or up into the text, the text highlight will 
disappear. Currently I'm workarounding it by pressing C-s C-s after each 
scroll, but I would like to know if there is an automatic way to do 
that. In other words, I would like to know what is the equivalent in 
emacs of the command / for man, less and vim.

Thanks in advance

You may want to check variable 'isearch-allow-scroll'

This is a good suggestion. But you may also want to know about "M-s o".

M-s o runs the command occur, which is an interactive compiled Lisp
function in `replace.el'.

It is bound to M-s o.

(occur REGEXP &optional NLINES)

Show all lines in the current buffer containing a match for REGEXP.
This function can not handle matches that span more than one line.

Thanks for the answers and sorry for the multiple messages, the M-s o is

very useful, but the isearch-allow-scroll doesn't work very well with me. It
will conserve the search if I do C-l or C-v, but won't if I use the mouse
scroll wheel or if I use the arrow keys to move the cursor (which are the
way I scroll the screen mostly). I want something that works similar to the
Linux man search, the vim or the gedit, that conserves the highlight as long
as the search is erased. Any other suggestions?

This is very strange, I tried it on emacs 24.0.50.1 when I read Qiang's 
response. And it worked like a charm. And now that you mention it, I 
tried it again on emacs 23.2.1. This time it behaves exactly as you 
describe!

For what it's worth, scrolling using the mouse works fine using: GNU
Emacs 24.0.50.1 (i386-mingw-nt6.1.7600) of 2010-07-12 on 3249CTO

Yes, I'm using version 23.1.1. I couldn't realize that this could be the 
version of emacs. I will install a newer version to check it out. 
Hopefully won't break with my .emacs config file :)
Many many thanks for your help

Hello back

After I recompiled my emacs to the 24.0.50.1, the problems of scrolling 
were solved mostly, but now after some time of usage I noticed a weird 
behaviour: Now that I can scroll freely, I noticed that it won't scroll 
beyond the position were the cursor is located (meaning that if I have 
one result in the line 150 and my text has 1000 lines and my buffer is 
80 lines tall, I can't scroll to see above the line 70 nor after the 
line 230), so I am limited to scrolling the buffer that is near a result 
of the searched text, and if I try to move the cursor away in order to 
scroll more or just to change some text around it will erase the search 
too (and I come back with the original problem again). Any idea to how 
to solve that?

Thanks for the attention

As far as I know, there is no way to get around that problem today. I
think the main issue is that in Emacs point is always in the visible
portion of the buffer.

Hi,

IMHO there is a way,

making functions doing de-highlighting conditional

(unless (or (eq last-command-event 'next)
           (eq last-command-event 'prior))

for example

(defun isearch-dehighlight ()
   (unless (or (eq last-command-event 'next)
               (eq last-command-event 'prior))
   (when isearch-overlay
     (delete-overlay isearch-overlay))))


same with

lazy-highlight-cleanup

and maybe some more.

Produces visible effect here.

Some more/other will arise nonetheless:
isearch highlighting is done in visible portion of buffer only.
Starting scroll with both changes as above will keep the highlights set 
so far, but not highlight further, now scrolled portion.


Cheers


Andreas

Well, I tried just the isearch-dehighlight, but it doesn't work at all. 
I will try to find by myself the solution using the tips you gave me 
(Not before I master emacs a little bit further, I'm just starting...).

In addition to some of the other suggestions, you can try Icicles search,
including `icicle-occur'.  You can keep the highlighting after searching (toggle
that on/off with `C-.' during search).  And you can scroll anywhere during
search (or afterward) - point is not tied to a search hit when you move the
focus from the minibuffer to your search-hits buffer.

This kind of search is quite different, so you will want to read up on it - do
not expect the same thing you are used to with isearch.

Essentially, all search hits are found for an initial regexp, and they are
presented to you as completion candidates.  You can navigate among the hits, and
you can narrow the set of hits by typing input that the candidates must also
match.  (IOW, you can search within the set of search hits.)

`icicle-occur' is a simplified version of this where the initial regexp is just
`.*', which matches all text in each line.  `icicle-occur' is on `C-''.
`icicle-search' (more general) is on `C-`'.

All the commands of icicles seems to be not defined (i.e. when I hit 
'M-x icicles' and them 'Tab', the auto-completion says that there is no 
match). It seems that those commands are not built-in in my emacs. I'm 
using GNU Emacs 24.0.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 
2.20.1). How can I download and install these commands or enable them 
while compiling? I compiled it by myself, so it is possible that I 
didn't selected the correct options while compiling.

Thanks for your attention

Icicles is not included in vanilla Emacs. If you want to try it, you need to
download the files.  This page tells you how:
http://www.emacswiki.org/cgi-bin/wiki/Icicles_-_Libraries

This is the main Icicles page (table of contents for the other pages):
http://www.emacswiki.org/emacs/Icicles

These pages provide in-depth overviews:
