Why emacsclient -e "(current-word nil t)" does not print ?

Why emacsclient -e "(current-word nil t)" does not print ?

[Wang Lei]

Hi, all.

I'm doing a piece of code. What needs get the output of
emacsclient -e "(current-word nil t)"

and send it to an external command. But there was NO output. I don't
understand.

Could someone explain that?

Thanks!

Try this command: 

  emacsclient -e "(current-buffer)"

And then look at the contents of the buffer, there you will find the
answer - but not much more. 8-)

That's because -e prints the result only when it's not nil.
Try:

    emacsclient -e "(or (current-word nil t) :nil)"

Actually, what am i interested is the "current word", in this line,
it's should print 't'. In emacs it does print 't'. But with
emacsclient, nothing.

Is this normal?

When executing a command with emacsclient, you're obviously in the
*server* buffer. It's empty, so current-word doesn't output anything.

Perhaps.   I cannot parse your sentence starting with "Actually".

Did you read what I wrote above?  I won't repeat it.



Otherwise, if you use emacsclient from within emacs (eg. from the M-x
shell) you will obviously get different results.  Once you hit RET,
emacs changes the position of the cursor, so the current word is not
the same as when you hit RET, and current-word will return nil.

And I don't see how current-word could return t.  At best, it could
return "t", if you had the cursor on a single letter 't'.

Perhaps that depends on the version of emacs, because with 22.2.1 I
get the current word:

$ emacsclient -e '(current-word)'
"Halley"

It's easy to see, of course:

   $ emacsclient -e '(buffer-name)'
   " *server*"

One can use `with-current-buffer' to specify what buffer to use, of course:

   $ emacsclient -e '(with-current-buffer "*scratch*" (current-word))'
   "oink"

("oink" happens to be what my cursor was on in the *scratch* buffer)

Yes. Maybe this is the reason, or maybe as Miles Bader said, it is in

Yes, I understand the meaning of the word "Actually", but it's the
whole sentence that I don't understand:

    Actually, what am i interested is the "current word", in this
    line, it's should print 't'.

What is the "it" that should print 't'?  

"current word" is two words, "current" and "word"...  Which of those
two words are you interested in?  The current word, or the word
"current", or the word "word"?  Or do you mean that "this line" refers
to another line?



>> Did you read what I wrote above?  I won't repeat it.
>>

So this shows that there is no current word, since current-word
returns nil, which my expression explicitely substitute with :nil.

I can confirm that with my version of emacs, I get the current buffer
and the current word:

$ emacsclient -e '(list emacs-version (buffer-name) (current-word))'
("22.2.1" "Main.cc" "FilterFunction")


>> And I don't see how current-word could return t.  At best, it could

With my emacs,

On a line alone, (current-word) C-x C-e  shows «"current-word"» in the mini buffer.

On a line alone, (current-word) SPC t C-b C-x C-e shows «"t"» in the mini buffer.

On a line alone, (current-word) SPC SPC t C-b C-b C-x C-e shows «"current-word"» in the mini buffer.

>What is the "it" that should print 't'?

In my (current-word nil t) C-x C-e shows "t" in minibuffer.
This "it" means this expression "(current-word nil t)".

>$ emacsclient -e '(list emacs-version (buffer-name) (current-word))'

Mine. In urxvt and emacs shell mode:
$emacsclient -e '(list emacs-version (buffer-name) (current-word))'
("23.1.50.1" " *server*" nil)

It looks like the output really depends on the version.

> Anyway, it proves what i have thought is wrong.
Here, I wanted to say I have tried to write a external program, that
gets the emacs' current word with emacsclient and send it to sdcv to
search. This is part of the whole function, the rest is to get it from
selection or prompt for. But now, it looks like i can not integrate
the emacs-part.

Ok, in this case, it's normal that you get "t" since that the word
that is before the cursor (just before the closing parenthesis) when
you type C-x C-e.

Yes.  But as mentionned by Miles, you can write a more complex
expression to select the buffer where you want to work:


$ emacsclient -e '(mapcar (function buffer-name)  (buffer-list))'
("some" "buffer" "names" ...)

$ emacsclient -e '(with-current-buffer "index" (current-word nil t))'
"source"

(You could, but you must know what buffer you want.)


Why do it from the exterior?  Stay with emacs.  Write an emacs command.

    (defun search-with-sdcv ()
       (interactive)
       (let ((word (current-word nil t)))
          (when word
             (shell-command (format "sdcv %S" word) "*sdcv output*" "*sdcv errors*"))))

Then  you may even bind that command to a key:

    (global-set-key (kbd "<F12>") 'search-with-sdcv)

so you just have one key to type to initiate that search from emacs,
without leaving emacs.

Actually, I don't know. I want the program can get any word in any
application to search. In applications like browser you have to rely
selection, but in emacs "mark" or "current-word" should be better.

Thanks for you code. I already have one. And I have wrote another, it
is a window manager extension, who can get word from selection or user
input. It is not necessary have two, so i thought to integrate them.

NOW. Maybe having two choices is ok. Because if I really want to
integrate everything, "get word from screen" should be my choice, not
selection ang prompt. Thanks for you help!

How about using the selected window? Its buffer can be obtained with
Emacs client:

emacsclient -e '(with-current-buffer (window-buffer (selected-window)) (current-word))'

So I understand that you really require to call your code from outside
of emacs. When you're not in emacs, there's AFAIK no way to tell which
buffer is "current". You may have many buffers, and also any number of
frames and windows. This code takes the buffer that the first window
of the currently selected frame is pointing to, which will probably do
what you want: 

  (with-current-buffer (window-buffer (frame-first-window)) (current-word nil t))
