Grab and yank

Grab and yank

[andrea]

I notice that I often do this operation:
I am in one buffer and I need to fetch something from another buffer.
So I visit the other one, select what I need, go back and yank.
Now something like that would be nice instead:
- visit the buffer in view mode
- when quitting automatically put it in kill-ring and yank it to the
  point of the original buffer

This would save quite a lot of time, what do you thik?
I started something like that

-8<---------------cut here---------------start------------->8---
 (defun grab-and-yank (buffer)
 "Grabs from another buffer and yank it to your point"
 (interactive "bbuffer:\n")
 (switch-to-buffer-other-window buffer)
 (view-mode 1))
--8<---------------cut here---------------end--------------->8---

But the view mode apparently don't keep it read only, and I think I
should change the keymap to make "q" do something different than just
exiting

I probably don't understand. What's wrong with this?

M-. foo ; go to foo's definition
C-M-h   ; select it
M-w     ; copy it
C-x b   ; return
C-y     ; yank

If that does what you want but you think it's too much work ;-), just roll it
into (a keyboard macro) or a command that uses `save-excursion' and the
constituent commands (`find-tag', `mark-defun', `kill-ring-save', and `yank').

A simple alternative, but which assumes that the function's definition is not
byte-compiled:

(defun grab (fn)
  (interactive "aFunction: ")
  (let ((strg (format "%s" (symbol-function fn))))
    (insert strg))) ; or use `insert-for-yank'

I thought it was a good idea so I just added something like it to
ourcomments-util.el. See the function ourcomments-set-paste-point
there.

You can find it in the nXhtml repository. (See EmacsWiki if you do not
know where it is.)

Ok I found it here
http://tinyurl.com/yzrt26b
and looks really nice, thanks.

Is it maybe possible to have a single commands that
- sets the point to where I am
- find a buffer and for me to select something
- bury it and paste when it's done

It's very close to what I would like already anyway, I can also try to
adapt it...

By the way is not my own business, but I see there are many nice things
in that file, and they don't have so much to do with a xml mode in
general.
Why don't make them part of something more generic somehow?

I think it is best keeping it separate so you can find the other
buffer any way you want to.

I doubt it is a good thing to make it too specialized. Maybe restoing
window configuration could be an option?

Because I do not have time for it then. Keeping it all in one bundle
is more simple.

I would like a package manager that could keep track of
interdependencies instead, but sofar no one else have been interested
really. I suggested a solution with web download of elisp files as you
need them which I think is what is needed. (It is implemented as part
of nXhtml too ;-) ... )

I polished it a bit and renamed it to ourcomments-copy+paste-set-point.

Hi Lennart,

thingatpt+ might be a good place for this?

It's an existing documented library of things that specialises in doing
"things at point"... nxhtml is rather heavy for many - although I
recommend it at every opportunity ;) Obviously if you prefer to keep it
in the domains of nxhtml that is your prerogative.

I think Andrea wanted something that:

 (a) goes and gets a function definition
     (from a tags file or the function's source code)
 (b) returns to the original location, and
 (c) yanks the definition at point.

The thing-at-pt functions pick up stuff at or near point.
They don't (and shouldn't) do excursion stuff or yanking.

That said, these functions in `thingatpt+.el' might be of some use in this
context: `region-or-word-nearest-point', `region-or-word-at-point'. They pick up
the active region or (if inactive) the word nearest/at point.

That was my thinking of it. And to be honest I'm not sure yank is out of
the realms of a "thing at pt" functionality. Anyway, I wanted to bring
attention to the library too since that might well help Andrea. I know
it did me when I first started scratching around trying to find simple
functions to get the word or region at pt without needing to learn about
the myriad of ways mark and point interact.

Hi,

what about the following procedure:

1) register your point
2) swirl around and collect your honey into a second register :-)
3) back to point (first register)
4 insert second register

If you want to do it "the GUI way", I remember an elisp package that
provided "single click copy&paste": just press the mouse-button at
start, drag to end, and when you release the mouse button, the selected
text is copied&yanked at point.
Can't remember the package's name, tho.
