Backward compatibility with old elisp packages is important.
Backward compatibility with old Emacs users is a bit less important.

Using M-s as a prefix might be a good idea.  What do others think?

Then we could use C-w for something more useful like getting the next
word from the buffer and appending it to the search string in the
minibuffer.  This would be very convenient since this is exactly what
C-w does in isearch mode.

This will allow us finally to get rid of isearch-yank-char-in-minibuffer
which does almost the same but in an unpredictable way.

I also noticed a similar command `bookmark-yank-word' in bookmark.el.
But when the mark is active, it doesn't kill the region.  I think
it should check for the active mark, and call `kill-region' in this
case like:

(defun bookmark-yank-word ()
  (interactive)
  ;; get the next word from the buffer and append it to the name of
  ;; the bookmark currently being set.
  (if mark-active
      (kill-region (point) (mark))
    (let ((string (save-excursion
		    (set-buffer bookmark-current-buffer)
		    (goto-char bookmark-yank-point)
		    (buffer-substring-no-properties
		     (point)
		     (progn
		       (forward-word 1)
		       (setq bookmark-yank-point (point)))))))
      (insert string))))

Generally, the logic could be the following: when C-w will fail anyway
due to the absence of the active mark in the minibuffer, do a different
action like pulling the next word from the buffer to the minibuffer.

BTW, in bookmark.el I see:

    ;; This C-u binding might not be very useful any more now that we
    ;; provide access to the default via the standard M-n binding.
    ;; Maybe we should just remove it?  --Stef-08
    (define-key map "\C-u" 'bookmark-insert-current-bookmark)

I agree that this is unnecessary any more, and if no one will object,
maybe we could just remove it?

Actually, I decided to leave it in, hence the comment.
The reason why I decided to leave it in, is that some users may like to
type something and then hit C-u which will *add* the default, whereas
M-n will repalce what they typed with the default.
Maybe I'm being overly cautious here and we can just throw away this
binding, but I don't know enough how other people may use bookmarks to
feel confident about it.

The current method of entering word search is very inconvenient.
So even if lots of people use it and we will find a better method,
they might be even grateful for this.

But I doubt that many people use it because for many years of existence
of word search, very few people tried to find a way to enable incremental
word search (according to mailing list archives) until recently.

Yes, it works after ? displayed the completions, i.e. it still yanks chars
from the original buffer, not from the completions buffer.

But I agree that this is not a reliable method.  Maybe we should record
the original buffer in a special variable before activating the minibuffer?

It is a really bad idea to start making editing commands work
differently in the minibuffer.

RE: Word search

[Drew Adams]

1. It might be OK to have C-w do something different when the region is
empty. At least for those people who use transient-mark mode (so that
"active region" means something).

2. That is not limited to the minibuffer, logically. That is, there is
nothing special about the minibuffer in this regard.

3. It is OK to have some minibuffer key yank text from the current buffer -
for example, text at or near point.

4. We have discussed #3 before. I suggested behavior that lets you yank
different kinds of things at point and behavior that lets you yank
successive things at point. Nothing has come of that, so far.

5. HOWEVER: If an approach such as #1 is used, it should not be combined
with #3, and especially not using `C-w'. That is trying to be too clever by
half, and it doesn't help.

That is, there is no reason to combine these features you propose. And doing
so limits design for the future. And the use of C-w then becomes confusing
for users: sometimes cut (kill), sometimes paste (yank). That's not good UI,
IMO.

So if you do #3, please use a different key. And if you do #1, consider
doing so in every buffer, not just the minibuffer.

C-w in the search string editing minibuffer is a natural extension of
C-w in isearch mode (`isearch-yank-word-or-char') because there will be
no difference between `C-s C-w C-w ...' and `C-s M-e C-w C-w ...'.

Since `isearch-edit-string' uses a normal minibuffer, it would be
natural to extend this C-w feature to other minibuffers.

But it is true that such dual nature of C-w might cause troubles
when transient-mark-mode is off.

Maybe, we could accept C-w as a yanking key only at the beginning of
the minibuffer?

I never realized it was there.  I remember trying C-y hoping for that, but
it inserts to the end of the line, something I never need.

I would prefer to have bindings similar to normal editing: C-y to yank, but
use M-y to insert the word at point, unless the previous command was yank.
Makes it easier to remember.

I used to poll the users by sending mail to info-gnu-emacs and

It's up to the maintainers to decide if they want to poll the users.

We currently have:

C-w isearch-yank-word-or-char
C-y isearch-yank-line
M-y isearch-yank-kill

Do you propose this change:

C-w isearch-yank-word-or-char
M-y isearch-yank-word-or-char
C-y isearch-yank-kill

But where do you put `isearch-yank-line'?

Hello valuated Emacs developpers,

Just to answer Richard's suggestion "let's ask them" and the wish to 
poll users : I am new to this mailing list and one suggestion I was 
going to make was concerning word search, when I discovered that this 
was already being discussed.

I am using Emacs mainly for editing LaTeX documents where auto-fill-mode 
+ indentation is active, and therefore word search is a must and 
incremental word search is a very very nice to have.

I fully agree with Juri's point that the current keys to enter word 
search is inconvenient, and I find the double meaning of C-w between 
usual editing and word search difficult (I would prefer to have a less 
easy to remember key to enter word search provided that that it does not 
overload the meaning of usual edition keys like C-w).

FYI, unfortunately I was never able to have word search work properly. 
For instance, when I try word search in the *info* node "Word search" 
and I type "C-sC-w" then I type "the words" (all of these things 
without double quotes) and then I type "", I would expect to find 
the first occurrence at the end of first line of info node text which is :

---- excerpt from info node Word Search --------------
Word search searches for a sequence of words without regard to how the
words are separated.  More precisely, you type a string of many words,
---- end of excerpt -------------------------------------

Instead of that, I get the following error message : 
"[(wrong-type-argument integer-or-marker-p t)]" which is displayed in 
the Minibuffer and has no trace in the *Message* buffer. Is that normal 
? My emacs version is "GNU Emacs 22.0.990.1 (i386-mingw-nt5.0.2195) of 
2007-05-31".

Sorry to dwell on it, if this is an already known or solved problem, I 
am jumping into this thread without having read all of it since the 
beginning.

BR,
        Vincent.

I get this error with emacs -Q, but not when I execute the following 
three lines:

(require 'cedet)
(semantic-load-enable-minimum-features)
(global-semantic-idle-summary-mode 1)

So something in the mess of macros and hooks that implements 
global-semantic-idle-summary-mode seems to be fixing the problem.

C-s C-w is not word search in the sense that you write below. C-s C-w yanks

That you for the information on the incremental word search 
("C-sM-eC-w"). I tested it on the same node, and whether I terminate by

RE: Word search

Two comments: (1) help-gnu-emacs@gnu.org might be a more appropriate list.
Consider moving this there. (2) Please use plain-text for these mailing lists.

	Sorry Drew, There was a mistake in my mail, I did not mean
      "C-sC-w" but I meant "C-sC-w".

What's the difference? They look the same to me.

      I tested it again and it does not work.
	
	That you for the information on the incremental word search

Not sure what you mean by terminate by "C-s" or by "". Does it at least work, in
the sense that it finds what you are looking for, regardless of how you
terminate the search? To terminate the search, you can just use RET or an arrow
key or another non-isearch key (except C-g). What do you mean by ""?

I have seen reports about `semantic' blocking isearch in Info because
it overwrites isearch functions with its own.  Even though it seems not
the problem reported by OP, I think we should find a way to avoid a
problem of conflicts between packages that redefine isearch functions.

But maybe there is no problem at all, if `semantic' doesn't really need
to change isearch functions in Info.  Then there is a bug in `semantic'
if it does this unintentionally.

Dear Drew,

I am realizing that there was no mistake in the mail before the latest 
one I sent, but that the mailing system has stripped off a part of it. 
What I meant was "C-sxxxC-w" where instread of "xxx" I had written "RET" 
between less-than and greater-than signs. But it seems that this xxx has 
been stripped off by the mailing system.
Similarly I meant that I terminated the interactive search by "C-s" or 
by "xxx" where xxx has the same meaning as above (a carriage return 
key). The fact is that I am writing to you with Thunderbird using an 
adds-on that allows to use hotmail without going through the Web 
interface (it seems that there is some bug with this when HTML is used).

More  answers embedded below (please read at least the last one) :

They were not the same when I sent the mail there was RET bracketted 
with LT and GT signs in between "C-s" and "C-w". So when I am sending 
this mail "C-sC-w" is different from "C-sC-w"

It does not find what I am looking for. When I type "C-sM-eC-w" I enter 
Incremental word search (I can see that as on the left side of the 
minibuffer is written "Word I-search").  Then if I type "the words" and 
then RET   I get an error message "[(wrong-type-argument 
integer-or-marker-p t)]" and the cursor of the *info* buffer remains at 
the same position, that is to say on the Top Left of the window, just on 
the "F" in "File: emacs,  Node: Word Search,  Next: Regexp Search,  
Prev: Nonincremental Search,  Up: Search"

More strange is the following: if I enter again the incremental word 
search, and I type on the right arrow key, what happens is that the 
content of the *info* buffer is copied character by character into the 
minibuffer. That is to say, assume that I type 5 times on the right 
arrow key, then the effect is as if I had entered the five characters 
"F" "i" "l" "e" and ":" consecutively (remember that when I enter the 
Word-I-search the *info* buffer point is pointing at the beginning the 
text "File: emacs,  Node: Word Search,  Next: Regexp Search,  Prev: 
Nonincremental Search,  Up: Search"

       Vincent.

I believe that is normal; the text is copied from the source buffer to the
isearch edit area. You then must hit RET to accept the edited text as your
search string. Then hit C-s to search for that text.

Re: Word search

[Vincent Belaïche]

Dear Drew,

Thank you for your patience with me, and sorry for the disturbance. 
Finally I created another email address on Google, because the one on 
hotmail was too difficult to use in plain text. Please tell me clearly 
if you wish me to file a bug and stop any disturbance on this developers 
only list as you seemed to suggest in your previous email.

I am writing again to you as I made some more investigation on my word 
search problem, and I have more news about it. Hereinafter I tried only 
non-interactive word search with the sequence "C-s<RET>C-w SEARCHED FOR 
WORD SEQUENCE <RET>".

1) It *DOES NOT FULLY* work in *info* node "Word Search", which is 
better than *FULLY DOES NOT WORK* :
1.1) In the case of an existing word sequence, it will not find it. If 
for instance I search for the word sequence "the words" it will not find 
it, whereas this word sequence is at end of 1st line of text. The search 
will exit with the message in the minibuffer "[(wrong-type-argument 
integer-or-marker-p t)]" tailing the current content of minibuffer.
1.2) however, in the case of a non existing word sequence, it will 
correctly exit indicating that the sequence does not exists. For 
instance if in the same node I search for the word sequence "Drew 
Adams", it will cleanly exit with the following content of the 
minibuffer "Failing word search: Drew Adams [initial mode]"

2) however it FULLY works in the *scratch* buffer : it does not find 
anything if the sequence does not exist in the buffer, and it finds 
something if the sequence does exists. If for instance I search for 
"evaluation If" it will correctly point at the end of first word in 
second line

3) When in the *info* node "Word Search"  messages appear between square 
bracket at the end of the search buffer, which is not the same behaviour 
as in other modes (such message do not occur there, maybe some traces 
intended for debug only have been forgotten to disable).

4) The failure does not depend of which *info* node is considered (I 
made the same type of test in the Top node, as the point value fits into 
16 bits there).

5) Still in the *info* node "Word Search", I switched the buffer to text 
mode by the sequence "M-x text-mode", then I tried to make the same word 
search (searching for "the words") and it worked !

6) I opened some LaTeX files of mine, and tested word search there, and 
it also works in LaTeX-mode.

7) Then, I simply tried "M-x word-search-forward" in the *info* node 
"Word search" that was again in info mode (not text mode) to make the 
word search, I entered the word sequence "the words", and it worked ! So 
this is very strange, word search does not work in info mode when it is 
invoked though the "C-s<RET>C-w" key sequence, but it does work if it is 
invoked directly by "M-x word-search-forward"


Sorry for the long mail, I am just hoping that this information is 
useful to Emacs developpers,
            Vincent.

PS-1: FYI, when I sent my 1st email, I thought that word search was not 
working at all in my environment because when I learn things from *info* 
I try them as I am reading the documentation. So even if word search is 
not that useful in *info* as such, it is useful in the sense that people 
trying the command as they read the document may be puzzled by not 
achieving it working, and then may not use the command at all as this 
was my case for years ! So I am spamming again this email list only for 
the benefit of the community : I personally don't need to make word 
searches in *info*, I need that only in LaTeX, and it works there.

PS-2: You wrote :

Sorry to have believed that an arrow key could be used to terminate the 
sequence of words to be searched for. Actually  I was trying ARROW RIGHT 
because in the mail you sent before you had written :

> To terminate the search, you can just use RET or an arrow
> key or another non-isearch key (except C-g).


I now am realizing that there was a misunderstanding, because I meant to 
terminate the word sequence to be searched for so that search is 
executed as it is in the sate when the search sequence is entered by 
user, and you understood that I was trying to terminate the incremental 
search processes whereas it is in the state when the search is waiting 
for some more command (e.g. to search next occurrence).

This made me realize that the documentation on incremental word search 
is not that clear, I may contribute later on on this. But I think that 
some other problems concerning the way as the incremental word search is 
invoked and accessed have to be solved first.

RE: Word search

Your latest mail seems clear enough. The only missing info is the Emacs version.
I see the same things you describe in the Emacs 22.1 release:

In GNU Emacs 22.1.1 (i386-mingw-nt5.1.2600)
 of 2007-06-02 on RELEASE
Windowing system distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (3.4) --cflags -Ic:/gnuwin32/include'

FYI, an advantage of using `M-x report-emacs-bug' is that it sends this info and
more along with your text, and it sends it to the proper mailing list, depending
on the Emacs version used. But what you have sent now seems clear enough.
Thanks.

Re: Word search

[Vincent Belaïche]

Dear Drew,

Here is the version information provided by the report-emacs-bug command

In GNU Emacs 22.0.990.1 (i386-mingw-nt5.0.2195)
  of 2007-05-31 on COCOTTE
Windowing system distributor `Microsoft Corp.', version 5.0.2195
configured using `configure --with-gcc (3.4) --cflags 
-Ic:/Programme/GnuWin32/include'

       Vincent

PS-1 : I am under the process of configuring my Emacs to send mail with 
it with the SMTP library, when this is done, I promise that I use 
report-emacs-bug ;-).
PS-2 : There is no such include path as "/Programme/GnuWin32/include" on 
my PC, it compiled with the minGw libs for Windows.

FYI - `M-x report-emacs-bug' should work with any mail client. You need not wait
until you configure Emacs to be your mail client.

I use `M-x report-emacs-bug' with MS Outlook as my mail client, for instance.
Exiting the bug report buffer with `C-c C-c' and confirming sending causes the
mail client to open a new message pre-addressed to the proper mailing list. I
just paste into the message body and then click Send. When you exit
`report-emacs-bug', it copies the report buffer contents, so you can immediately
paste them into your mail body.

Of course, if you do use Emacs for your mail client, so much the better. HTH.
