I've noticed that when I execute ess-eval-line-visibly-and-step inside an R-mode buffer and I don't already have an active R session, it will split the screen (good), however it will show both sides of the split into the R session (bad). I would expect it to split the screen and show the R session on one side (ideally the right) and leave the R-mode buffer on the other side (ideally the left).
The only bit of my init.el referencing ESS is
(use-package ess
:ensure t
:defer t
:config
(setq ess-ask-for-ess-directory nil ;; just run R wherever
;; the file lives

I've commented out all the setq and it doesn't fix the issue.

I am very bad at customizing emacs. I desire that if i start with a file ending in ".r", emacs starts maximized, with two windows side by side (vertical division of the frame), in one my source code file, and in the other the ESS R interpreter. If I can understand the example, maybe I can generalize it to other extensions and modes. I still do not get the syntax of hooks in elisp.
The usual way to use Emacs is to have it always running instead of
opening and closing it all the time.
I suggest that you define a function that would make an existing Emacs
look the way you want:
(defun my-R-window-configuration ()
"Prepare the current emacs frame for R work."
(interactive)
;; maximimize the current frame:
(set-frame-parameter nil 'fullscreen 'maximized)
;; keep just the current window, presumably containing the R code
(delete-other-windows)
;; create ESS R interaction buffer and go there
(ess-switch-to-end-of-ESS)
;; go back to the code
(other-window 1))
Now you can do M-x my-R-window-configuration RET in an R buffer to get what you want.
Disclaimer: I'm quite new to spacemacs and emacs so I'm probably missing something very obvious. Whenever I attempt to use auto-complete in a javascript file (with js2-mode), I get the following messages:
Error running timer `ac-update-greedy': (error "js2-name-node-name accessing a non-js2-name-node")
Error running timer `ac-show-menu': (error "js2-name-node-name accessing a non-js2-name-node")

However, auto-complete does appear to work in emacs-lisp (discovered when editing the spacemacs config file.
If you installed full version of spacemacs and use vim editing style:
1. use <spc> f e d to open .spacemacs file
2. find dotspacemacs-configuration-layers,this should be a list of layers
3. auto-completionshould already be in the list, but commented out. Just enable it by remove the comment mark before.
4. in normal mode, invoke <spc> f e R to install required packages, or simply restart emacs
Edit: What the poster calls a "window", Emacs calls a "frame". I fixed the title.
Concisely, the question is: in a window, how do I switch quickly to a buffer previously visited in that window, even if it's already opened in another window?
A more detailed description follows.
Normally, in order to switch window to previous buffer one just types C-x b RET. That is, the default argument to switch-to-buffer (or ido-switch-buffer) is the previous buffer.
This is not, however, the case when that (previous) buffer is already shown in another window. That's exactly what bugs me.
Let's consider an example. Suppose I have three buffers (A, B and C) and two windows showing buffers A and B (C is not visible at this point).
Then I open buffer A in the second window, too. So, now I have buffer A shown in both windows. Then I switch (C-x b RET) to B again. After that, C-x b RET will bring me not to A, but to C because A is already shown in the other window.
How do I make C-x b RET behave more consistently?
Update
After this problem had been solved, I realized I needed more: namely, for point position to be remembered per-window, not per buffer. Luckily, there're ready-made solutions:
winpoint
per-window-point
They're quite similar; for a discussion of differences see here.
I've found a fix for switch-to-buffer. It eventually calls
(other-buffer (current-buffer))
while in order to fix your problem, the call needs to look like this:
(other-buffer (current-buffer) t)
i.e. the visible-ok argument needs to be t.
Here's an advice to have it always at t. Hopefully it won't break other stuff that uses other-buffer:
(defadvice other-buffer (around fix-switch-to-buffer
(&optional buffer visible-ok frame) activate)
(setq visible-ok t)
ad-do-it)
Note that ido-switch-to-buffer uses a different machinery, so a different method is needed to fix it.
update: fix for ido-switch-to-buffer
I needed to re-define ido-make-buffer-list:
(defun ido-make-buffer-list (default)
(let* ((ido-current-buffers (list (buffer-name (current-buffer))))
(ido-temp-list (ido-make-buffer-list-1 (selected-frame) ido-current-buffers)))
(if ido-temp-list
(nconc ido-temp-list ido-current-buffers)
(setq ido-temp-list ido-current-buffers))
(if default
(setq ido-temp-list
(cons default (delete default ido-temp-list))))
(if (bound-and-true-p ido-enable-virtual-buffers)
(ido-add-virtual-buffers-to-list))
(run-hooks 'ido-make-buffer-list-hook)
ido-temp-list))
The diff is just one line, but it's too messy to advice it.
update: use new advice system for other-buffer
The old stuff should still work for quite a while, but here's the new approach:
(defun other-buffer-advice (orig-fun &optional buffer visible-ok frame)
(funcall orig-fun buffer t frame))
(advice-add 'other-buffer :around #'other-buffer-advice)
;; (advice-remove 'other-buffer :around #'other-buffer-advice)
Instead of advising the built-in function other-buffer, you can pre-select visible buffers using a package.
1 Using Ivy
If you're using Ivy, you can use abo-abo's approach to override the lower-use function ivy-switch-buffer.
(defun user/ivy-switch-buffer ()
"Switch to another buffer with visible-ok preselection."
(interactive)
(ivy-read "Switch to buffer: " #'internal-complete-buffer
:keymap ivy-switch-buffer-map
:preselect (buffer-name (other-buffer (current-buffer) t))
:action #'ivy--switch-buffer-action
:matcher #'ivy--switch-buffer-matcher
:caller 'ivy-switch-buffer))
(advice-add 'ivy-switch-buffer :override #'user/ivy-switch-buffer)
2 Using Ido mode
2.1 Switching to a buffer shown in another frame
If by "window" you really mean "frame" (i.e., you'd like to ido-switch-buffer to a buffer that is currently shown in another frame), then ido-mode gives you the behavior you're looking for when you change ido-default-buffer-method from its default value of raise-frame to selected-window:
(setq ido-default-buffer-method 'selected-window)
Emacs constructs an independent buffer list for each frame, so the only thing you have to do is to configure Ido to avoid jumping to another frame when you switch buffers.
2.2 Switching to a buffer that is shown in another window inside the same frame
To get this behavior across windows within the same frame, you should hook a function that reorders the buffer list onto ido-make-buffer-list-hook.
From ido.el:
;; Changing the list of files
;; --------------------------
;; By default, the list of current files is most recent first,
;; oldest last, with the exception that the files visible in the
;; current frame are put at the end of the list. A hook exists to
;; allow other functions to order the list. For example, if you add:
;;
;; (add-hook 'ido-make-buffer-list-hook 'ido-summary-buffers-to-end)
;;
;; then all files matching "Summary" are moved to the end of the
;; list. (I find this handy for keeping the INBOX Summary and so on
;; out of the way.) It also moves files matching "output\*$" to the
;; end of the list (these are created by AUCTeX when compiling.)
;; Other functions could be made available which alter the list of
;; matching files (either deleting or rearranging elements.)
I'm having a hard time making this emacs -nw work effectively under the terminal mode (emacs -nw).
Some setup information:
The working server is connected via SSH, and emacs is running on the server. Usually I'm connecting using SSH and "emacs -nw" to work on my files.
The emacs config is picked up from: https://hugoheden.wordpress.com/2009/03/08/copypaste-with-emacs-in-terminal/

))
The reason to have:
(require 'mouse)
(xterm-mouse-mode t)
(defun track-mouse (e))
(setq mouse-sel-mode t)
is to enable mouse selection over text such that the text region is highlighted just as "C-x SPC" marking the region. Then I can use "M-x w" to copy and "C-x y" to paste text within emacs and between emacs and other apps.
All look perfect except that any operations related to X are REALLY SLOW! My connection to the remote server is smooth -- the latency is usually under 100ms. But to kill one line of text using "C-x k", it takes ~5 seconds! To paste it, it takes another 5 seconds!
When copy/paste is frequent sometimes, this becomes really annoying. I think this is related to the X sever messaging, but not sure if there is good way to fix this.
Any ideas?
Thanks!
This is not an ideal solution per se, but i figured out a way that I feel better than the previous one.
The idea is to get rid of X which causes heavy latency issues, i.e. keep only the following:
;; enable clipboard in emacs
(setq x-select-enable-clipboard t)
The results are:
copy/paste within Emacs is straightforward and fast.
copy from other apps to Emacs: Ctrl+Shift+v
copy from Emacs to other apps: mouse selection is now on X Selection, so right-click and copy shall copy the text into the Selection. Note that 'M-w" now won't copy anything into Selection or system clipboard.
This is again a compromise rather than a solution, but considering the fact that i copy/paste more often than inter-app operations, this is acceptable at the moment.
Still looking forward to a good solution!
You can accomplish this by using a terminal escape code!
There is a unique category of terminal escape codes called "Operating System Controls" (OSC) and one of these sequences (\033]52) is meant for interacting with the system clipboard. The great thing is that your terminal doesn't care where the code came from so it will work in remote sessions as well.
Most terminal emulators support it (iTerm2, OS X Terminal, and I think all Linux terminals besides GNOME). You can test if your terminal supports this sequence by simply running:
$ printf "\033]52;c;$(printf "Hello, world" | base64)\a"
Then paste from your system clipboard. If it pastes "Hello, world" then your terminal supports it!
I have this function in my init.el so when I call yank-to-clipboard Emacs will yank the value from my kill ring into the system clipboard:
(defun yank-to-clipboard ()
"Use ANSI OSC 52 escape sequence to attempt clipboard copy"
(interactive)
(send-string-to-terminal
(format "\033]52;c;%s\a"
(base64-encode-string
(encode-coding-string
(substring-no-properties
(nth 0 kill-ring)) 'utf-8) t))))
As I type this, I stumbled upon an almost-identical script supported by Chromium community: https://chromium.googlesource.com/apps/libapps/+/master/hterm/etc/osc52.el
For those running Emacs inside Tmux:
Tmux consumes the sequence, so you'll need to pipe the sequence to the Tmux active tty for this to work. I have a solution in my blog post here: https://justinchips.medium.com/have-vim-emacs-tmux-use-system-clipboard-4c9d901eef40
To extend on #justinokamoto's answer for use in tmux, it works great and is truly amazing. I haven't debugged it with e.g. tramp or other fancy emacs settings but to get it to work
Follow https://sunaku.github.io/tmux-yank-osc52.html great instructions, modifying your tmux.conf and ~/bin/yank
Make sure terminal access to your clipboard is enabled on your terminal
Then to pull into emacs you can use a function like:
(Caveat emptor, I am very new to elisp. This writes to a temporary file in /tmp/yank)
(defun custom-terminal-yank (&rest args)
(message "-> CLIP")
;; FOR EVIL MODE: UNCOMMENT SO FIRST YANKS TO KILL RING
;; need to yank first, with all those args
;; ;; https://emacs.stackexchange.com/questions/19215/how-to-write-a-transparent-pass-through-function-wrapper
;; (interactive (advice-eval-interactive-spec
;; (cadr (interactive-form #'evil-yank))))
;; (apply #'evil-yank args)
;; https://stackoverflow.com/questions/27764059/emacs-terminal-mode-how-to-copy-and-paste-efficiently
;; https://sunaku.github.io/tmux-yank-osc52.html
(f-write-text (nth 0 kill-ring) 'utf-8 "/tmp/yank")
(send-string-to-terminal (shell-command-to-string "~/bin/yank /tmp/yank"))
)
If anyone else uses evil mode as well (just to make things complicated) you can uncomment those lines and use something like
(define-key evil-visual-state-map "Y" 'jonah-terminal-yank)
So that normal "y" is for normal yanking in visual mode, but "Y" is for cross-clipboard yanking
