I have some custom scrolling functions in Emacs, which help me get around a bug where a single scroll event sends two <mouse-4> or <mouse-5> actions. I have:
(setq scroll-down-this-time t)
(defun my-scroll-down-line ()
(interactive "#")
(if scroll-down-this-time
(progn
(scroll-down-line)
(setq scroll-down-this-time nil))
(setq scroll-down-this-time t)))
(setq scroll-up-this-time t)
(defun my-scroll-up-line ()
(interactive "#")
(if scroll-up-this-time
(progn
(scroll-up-line)
(setq scroll-up-this-time nil))
(setq scroll-up-this-time t)))
(global-set-key (kbd "<mouse-4>") 'my-scroll-down-line)
(global-set-key (kbd "<mouse-5>") 'my-scroll-up-line)
This works perfectly, except that the (interactive "#") isn't exactly what I want. This causes whatever buffer that is under the mouse to scroll and to gain the keyboard focus. I want a way to make it scroll, but not steal the keyboard focus (like (setq mouse-wheel-follow-mouse 't) does for the normal scrolling library). How might I achieve this?
I am using the development version of Emacs, so don't be afraid to give me any new features.
You should not redefine <mouse-4> and <mouse-5>, but instead:
(mouse-wheel-mode 1)
(defvar alternating-scroll-down-next t)
(defvar alternating-scroll-up-next t)
(defun alternating-scroll-down-line (&optional arg)
(when alternating-scroll-down-next
(scroll-down-line (or arg 1)))
(setq alternating-scroll-down-next (not alternating-scroll-down-next)))
(defun alternating-scroll-up-line (&optional arg)
(when alternating-scroll-up-next
(scroll-up-line (or arg 1)))
(setq alternating-scroll-up-next (not alternating-scroll-up-next)))
(setq mwheel-scroll-up-function 'alternating-scroll-up-line)
(setq mwheel-scroll-down-function 'alternating-scroll-down-line)

And I dont want this behavior. Actually, not everytime is focus switched. For example, buffers like *Help* or *Message* does not have this behavior, this unwanted feature is active only when closing regular file buffers.
How to disable this feature completelly ?
My solution for this problem is simply write my own handler for buffer kill. Hope it will help someone in future.
(global-set-key (kbd "C-w")
(lambda ()
(interactive)
(if (string= (substring (buffer-name) 0 2) " *")
(progn
(message "You can not kill protected BUFFER"))
(progn
(if (string= (substring (buffer-name) 0 1) "*")
(progn
(call-interactively 'kill-buffer))
(progn
(call-interactively 'kill-buffer)
(run-at-time "0.5 sec" nil
(lambda ()
(call-interactively 'windmove-right)))))))))
You need to have installed ace-window package for windmove-right, that feature with protected buffers is not relevant to this answer so you can freely remove it.
I'm trying to use Document View in Emacs to read PDFs, but I can't figure out how to make it behave similarly to the 'fit to width' command many PDF readers have. Is there an internal way to do this?
The following snippet defines a new minor-mode doc-view-autofit-mode, which I have activated below using doc-view-mode-hook. It works for me on Emacs 24.3 on Ubuntu 14.04, even to the point of resizing the zoom when I resize the window!
(There is usually a short resize delay thanks to doc-view-autofit-timer-start, but I'm happy to live with this.)
I take no credit for the solution; I found this code on the emacs-devel mailing list.

It works for me:
(add-hook 'doc-view-mode-hook 'doc-view-fit-width-to-window)
Update: It doesn't work correctly if a conversion (to png or something else) is still ongoing (First opening the document). There is alternative, more reliable way, which handles this special case (it doesn't use hook at all but uses advice):
(defadvice doc-view-display (after fit-width activate)
(doc-view-fit-width-to-window))
The following is a slight modification of the answer by Chris -- it provides compatibility with functions like find-file-other-window -- e.g., when the selected-window is different than the one displaying the *.pdf file.
(defvar last-displayed-doc-view-buffer nil)
(defun get-last-displayed-doc-view-buffer ()
(setq last-displayed-doc-view-buffer (current-buffer)))
(add-hook 'doc-view-mode-hook 'get-last-displayed-doc-view-buffer)
(defun doc-view-autofit-fit ()
"Fits the document in the selected window's buffer
delayed with a timer, so multiple calls in succession
don't cause as much overhead."
(if (null doc-view-autofit-timer)
(setq doc-view-autofit-timer
(run-with-timer doc-view-autofit-timer-start nil (lambda ()
(let* (
(selected-window
(cond
((eq major-mode 'doc-view-mode)
(selected-window))
(t
(get-buffer-window last-displayed-doc-view-buffer))))
(current-buffer
(cond
((eq major-mode 'doc-view-mode)
(current-buffer))
(t
(get-buffer last-displayed-doc-view-buffer))))
(selected-fit
(when (buffer-live-p (get-buffer current-buffer))
(with-current-buffer (get-buffer current-buffer)
doc-view-autofit-type))) )
(when (window-live-p selected-window)
(with-selected-window selected-window
(when doc-view-autofit-timer (cancel-timer doc-view-autofit-timer))
(setq doc-view-autofit-timer nil)
(cond
((eq 'width selected-fit)
(doc-view-fit-width-to-window))
((eq 'height selected-fit)
(doc-view-fit-height-to-window))
((eq 'page selected-fit)
(doc-view-fit-page-to-window)))))))))
(timer-inc-time doc-view-autofit-timer doc-view-autofit-timer-inc)))
And, as noted in my earlier comment to Chris' answer, the following variables need definitions:
(defvar doc-view-autofit-timer nil)
(defvar doc-view-autofit-type nil)
Because the modification above adds a new function to the doc-view-mode-hook to obtain the current-buffer, which is needed for the function doc-view-autofit-fit, it is necessary to ensure that the latter function is appended to the end of the doc-view-mode-hook. So the change looks like this -- i.e., we add a t for the append argument:
(add-hook 'doc-view-mode-hook 'doc-view-autofit-mode t)
Everything else from Chris's answer that has not been superseded by the above modifications remain in effect.
TO DO:
Create a test to examine each page while scrolling to make certain that the view coincides with the autofit-type. Presently, errors occur in page size when dealing with a long *.pdf file.
Just a note: (require 'cl) is out of date. Since emacs-24.3 it should be

See http://www.emacswiki.org/emacs/CommonLispForEmacs
In GNU Emacs for OSX, how can I keep the kill ring and OSX clipboard separate? (Such that I essentially have two separate kill rings.)
With desired behavior, this would work:
1. ⌘C to copy text from the web to OSX clipboard.
2. controlk to kill a line in Emacs.
3. controly to yank killed text from Emacs kill ring to current Emacs buffer.
4. ⌘v to paste original web text from OSX clipboard to current Emacs buffer.
This works out of the box in Aquamacs. How to make work in GNU Emacs?
This question was discussed as it pertains to Windows here:
Emacs: How to separate the kill ring from the system clipboard?
and here:
http://lists.gnu.org/archive/html/help-emacs-windows/2010-02/msg00001.HTML
...but this solution does not work in OSX. I would like a solution for Mac OSX.
The solution in Emacs: How to separate the kill ring from the system clipboard? does work, though not complete. You may call pbcopy yourself to get clipboard pasting right. For instance, try the following in your .emacs. Note that s-v is for Cmd+V in an OS X window system. Same goes for s-c.

After much fiddling around, I'm pretty sure that the only way to make this work is to override the x-select-text method. Check out my answer here for all the details: https://stackoverflow.com/a/23254771/71522
NOTE: This draft solution is not meant to be an Emacs system-wide modification separating the clipboards -- instead, this is a custom solution designed to keep the clipboards separated on an interactive basis only when specifically using these custom functions. Other functions within
Emacs that use the kill-ring can be modified using a similar method -- the variables interprogram-cut-function and interprogram-paste-function can be made let-bound to a nil value for the duration of the specific functions (either through advice, or modification of the source itself, or creating new functions and/or using a defalias). However, the latter is beyond the scope of this limited example.
HISTORY
First Draft (December 23, 2014): This is a first draft, which is based on the idea that the OSX clipboard may be accessed only when using C-u before calling either the copy or paste functions. If C-u is called first, then the OSX clipboard is utilized. As I use the functions more on a daily basis, I may have additional revisions to this code and I will update same from time to time:
EDIT (December 24, 2014): Removed * from the interactive command statement as to lawlist-copy-selected-region -- that was a read-only check needed for pasting, but not copying. Added a statement regarding the general nature of this example.
EDIT (December 28, 2014): Revised code to better handle when the user forgot to select a region before calling lawlist-copy-selected-region. Small revisions to make the code more concise.

simpleclip might be helpful -
Simplified access to the system clipboard in Emacs.
simpleclip-mode radically simplifies clipboard handling: the system
clipboard and the Emacs kill ring are made completely independent, and
never influence each other.
The super keybindings are friendly for OS X: super is generally mapped
to the "command" key ie ⌘.
Tested on OS X, X11, and MS Windows
https://github.com/rolandwalker/simpleclip
Use
(setq select-enable-clipboard nil)
This will only separate the two clipboards, and for ⌘ c and ⌘ v to work like mentioned you will have to rebind them to clipboard-kill-ring-save and clipboard-yank:
(keymap-global-set "s-c" 'clipboard-kill-ring-save)
(keymap-global-set "s-x" 'clipboard-kill-region)
(keymap-global-set "s-v" 'clipboard-yank)
I am using this Emacs: https://github.com/railwaycat/emacs-mac-port, and it also works on Emacs 28 built from source.
I want to make the compilation window in Emacs to always appear at the bottom of a window, and always be a certain height. So far I put the following lines in my .emacs file:
(setq split-height-threshold 0)
(setq compilation-window-height 10)
...and it does work for when I have only one window open, but as soon as I split the screen into two windows horizontally (that is, the dividing line in the middle goes from the top to the bottom), the compilation window stops respecting the height variable, and splits the window right in the middle.
How do I fix this?
I would use something like this, freely adapted from the EmacsWiki:
(defun my-compilation-hook ()
(when (not (get-buffer-window "*compilation*"))
(save-selected-window
(save-excursion
(let* ((w (split-window-vertically))
(h (window-height w)))
(select-window w)
(switch-to-buffer "*compilation*")
(shrink-window (- h compilation-window-height)))))))
(add-hook 'compilation-mode-hook 'my-compilation-hook)
If the *compilation* buffer is not visible, this will split the window vertically, resize the newly opened window to 10 lines height, and open the *compilation* buffer in it.
You can customize the variable compilation-window-height.
Combining code from How can I prevent emacs from opening new window for compilation output? and code from http://www.emacswiki.org/emacs/CompilationMode, this is all my code for compile, it provides you 4 features:
1). Use compile-again to run the same compile as the last time automatically, no prompt. If there is no last time, or there is a prefix argument, it acts like M-x compile.
2). compile will split the current window(always be a certain size), it will not affect the other windows in this frame.
3). it will auto-close the *compilation* buffer (window) if there is no error, keep it if error exists.
4). it will highlight the error line and line number of the source code in the *compilation* buffer, use M-n/p to navigate every error in *compilation* buffer, Enter in the error line to jump to the line in your code code.
(require 'compile)
(setq compilation-last-buffer nil)
(defun compile-again (ARG)
"Run the same compile as the last time.
If there is no last time, or there is a prefix argument, this acts like M-x compile."

There's an excellent package for these situations named Shackle. https://github.com/wasamasa/shackle
Easy to set up and works on pretty much any type of buffer
When I use grep-find it opens another window (area in the frame) with a list of results that I can select. When I select one it opens the target file in a different window than grep-find is in.
How can I get the target file to open in the same window as the grep results (replacing the grep results window with what I am actually looking for).
How can I keep grep-find from opening a separate window (have it so it opens in the current window). My goal is I look for something, I find it, I go to it, all within the same window. I would like to add this to my .emacs file.
It doesn't look like there is any way to configure the compile package to do what you're asking. And there's no easy way to use advice to tweak the behavior. I think you have to resort to editing the function which actually jumps to the error, which you can do with the following addition to your .emacs (tested in Emacs 23.1):
(eval-after-load "compile"
'(defun compilation-goto-locus (msg mk end-mk)
"Jump to an error corresponding to MSG at MK.
All arguments are markers. If END-MK is non-nil, mark is set there
and overlay is highlighted between MK and END-MK."
;; Show compilation buffer in other window, scrolled to this error.
(let* ((from-compilation-buffer (eq (window-buffer (selected-window))
(marker-buffer msg)))
;; Use an existing window if it is in a visible frame.
(pre-existing (get-buffer-window (marker-buffer msg) 0))

The eval-afer-load portion just ensures that you re-define it after Emacs defined it, so that your change takes hold.
You can add a binding (e.g. Alt-m) and do the following
(define-key grep-mode-map "\M-m" (lambda()
(interactive)
(compile-goto-error)
(delete-other-windows)
(kill-buffer "*grep*")))
I didn't find a way to replace the standard "Enter" / Mouse-click binding with a custom function
There is an another approach:
(defun eab/compile-goto-error ()
(interactive)
(let ((cwc (current-window-configuration)))
(funcall
`(lambda ()
(defun eab/compile-goto-error-internal ()
(let ((cb (current-buffer))
(p (point)))
(set-window-configuration ,cwc)
(switch-to-buffer cb)
(goto-char p ))))))
(compile-goto-error)
(run-with-timer 0.01 nil 'eab/compile-goto-error-internal))
I had the same question, and found this answer over at emacs.stackexchange https://emacs.stackexchange.com/a/33908/20000
(defun my-compile-goto-error-same-window ()
(interactive)
(let ((display-buffer-overriding-action
'((display-buffer-reuse-window
display-buffer-same-window)
(inhibit-same-window . nil))))
(call-interactively #'compile-goto-error)))
(defun my-compilation-mode-hook ()
(local-set-key (kbd "o") #'my-compile-goto-error-same-window))
(add-hook 'compilation-mode-hook #'my-compilation-mode-hook)
Pressing o in the *grep* buffer will open the location and file in the same frame.
I found this an elegant solution without deleting frames or too much lisp code and just hooking into compilation-mode-hook.
