I load a .m file into emacs.
When I do (alt x + run-octave) I get the message:"process Inferior Octave exited abnormally with code 57.
I added to the .emacs the lines "(autoload 'octave-mode "octave-mod" nil t)
(setq auto-mode-alist
(cons '("\.m$" . octave-mode) auto-mode-alist))", per the suggestion of " https://www.gnu.org/software/octave/doc/interpreter/Running-Octave-from-Within-Emacs.html",
but, It did not make any differnce.
How should I set-up emacs, so that I will be able to run octave on it's .m files?

When I launch an ipython process in an emacs buffer, it prints trash text to the buffer:
^[[J^[[?7h^[[?12l^[[?25h^[[?2004l
^[[?12l^[[?25h
The ipython buffer does this every time I launch it, every time I evaluate code in another buffer, every time I evaluate code in that buffer. Ipython never does this from the bash CLI, In [1]:
Where could I look to change this behavior to a more sensible and terse prompt, such as what ipython does in bash?
This is in emacs 24.5.1 inside tmux 2.0 with python 2.7.6, ipython 5.1.0, python-mode version 6.2.1, running on Ubuntu 14.04 LTS.
Here's every line in my .emacs file that even mentions python:
; (require 'python-settings)
; (require 'ein)
(setq py-install-directory "~/.emacs.d/python-mode")
(add-to-list 'load-path py-install-directory)

;; responsible for the annoying window rearrangement behavior after every code execution? Nope.

what Thomas K suggests is the actual solution, just edit your init.el file and paste the following:
RUN IPYTHON6.4 IN EMACS ALONG WITH PYTHON3+
(setq python-shell-interpreter "ipython3"
python-shell-interpreter-args "-i --simple-prompt")
I'm trying to use the Edinburgh Concurrency Workbench (http://homepages.inf.ed.ac.uk/perdita/cwb/) with Emacs under Windows. I have placed the file cwb.el under C:\emacs\emacs-22.3\emacs-stuff. My .emacs file is located at C:\emacs and has the following content:
(setq load-path ; Look in my own library first.
(cons (expand-file-name "C:\emacs\emacs-22.3\emacsstuff")
load-path))
(autoload 'cwb "cwb" "Run a CWB process." t)
(autoload 'cwb-file-mode "cwb" "Major mode for editing CWB source." t)
(add-hook 'cwb-load-hook
(function
(lambda ()
(setq cwb-program-name "cwb7")))) ;; only necessary if your v7 isn't
;; called cwb
Yet, when I enter "M-x cwb", I get "Cannot open load file: cwb".
I tried to follow the instruction here: http://homepages.inf.ed.ac.uk/perdita/cwb/doc/emacs.html.
Thanks
In Emacs Lisp strings, backslash is an escape character, similar to C, so "C:\emacs\emacs-22.3\emacsstuff" ends up being "C:^[macs^[macs-22.3^[macsstuff". (You can try it with either M-: or M-x ielm.)
You can either write the path with forward slashes instead ("C:/emacs/emacs-22.3/emacsstuff") or use double backslashes ("C:\\emacs\\emacs-22.3\\emacsstuff").
I want to knit AND latexmk Knitr documents using one AUCtex command.
I don't know how to code in lisp, and web search didn't turn up anything like this.
I have something close. The extension of the file needs to be changed for latexmk.
Any help will be appreciated.
Following line is for my .emacs file.
(add-hook 'LaTeX-mode-hook (lambda () (push '
("KnitrLaTeX" "Rscript -e \"library(knitr)\; knit('%s')\" && latexmk -pdf %s"
TeX-run-TeX nil t :help "Run knitr and latexmk on file")
TeX-command-list)))
When I run C-c C-c (KnitrLaTeX), emacs runs the following command:
Running `KnitrLaTeX' on `slides.Rnw' with ``Rscript -e "library(knitr); knit('slides.Rnw')" && latexmk -pdf slides.Rnw''
Which is wrong. It should read "... && latexmk -pdf slides.tex"
Thanks in advance.
It appears that you are having trouble with how the second usage of %s is being interpreted at the tail end of your compile command -- i.e., you want the second usage of %s to mean slides.tex instead of slides.Rnw.
Although I am not familiar with knit, I am familiar with creating custom variables for use with AUCTeX. Set forth below are some examples of how to create custom variables and add them to the TeX-expand-list.
Rather than of using %s for a second time (i.e., at the tail end of your compilation command), perhaps consider using %(tex-file-name) instead. This assumes that your *.tex file is open in the buffer with focus when you begin your compilation command -- i.e., the full file name will be inserted into your compilation command.
If you have a file with a different extension that is open in the buffer with focus when you run your compilation command, and if you want the base name to be the same (but with a different extension), then you would do something similar to the example of %(pdf-file-name) -- i.e., remove whatever extension is there and replace it with the new one.
(eval-after-load "tex" '(progn
(add-to-list 'TeX-expand-list '("%(tex-file-name)" (lambda ()
(concat "\"" (buffer-file-name) "\""))))
(add-to-list 'TeX-expand-list '("%(pdf-file-name)" (lambda ()
(concat
"\"" (car (split-string (buffer-file-name) "\\.tex"))
".pdf" "\""))))
(add-to-list 'TeX-expand-list '("%(line-number)" (lambda ()
(format "%d" (line-number-at-pos))))) ))
I am running emacs 23.3.1 on ubuntu 12.04 with auctex 11.86. Whenever I go to compile a latex document (using C-c C-c), if there are no errors, everything compiles just fine. However, if there are any errors it will tell me to use C-` to view errors, if I do so, I get this error message
Use M-x make-directory RET RET to create the directory and its parents
and it goes away after a couple seconds. Then it takes me to another screen that explains the error in the latex code. However, now I cannot simply do C-x 1 to get back to the latex code. I have to C-x C-c and restart emacs.
This is my .emacs file

Sometimes AUCTeX gets confused parsing the log of (La)TeX compilation and isn't able to guess the correct line raising the error. In some cases AUCTeX issues an obscure message "Error occured after last TeX file closed", when there are unbalanced parentheses, in your case it suggests you to create a new directory. To help AUCTeX finding the correct line raising the error you can add the -file-line-error option to latex or pdflatex by customizing the variable LaTeX-command-style. To do this add the following code to your .emacs:
(setq LaTeX-command-style '(("" "%(PDF)%(latex) -file-line-error %S%(PDFout)")))
See also the AUCTeX FAQ:
8. Why does TeX-next-error (C-c `) fail?
When writing the log file, TeX puts information related to a file,
including error messages, between a pair of parentheses. AUCTeX
determines the file where the error happened by parsing the log file
and counting the parentheses. This can fail when there are other,
unbalanced parentheses present.
As a workaround you can activate so-called file:line:error messages
for the log file. (Those are are easier to parse, but may lack some
details.) Either you do this in the configuration of your TeX system
(consult its manual to see where this is) or you add a command line
switch to the (la)tex call, e.g. by customizing LaTeX-command-style or
TeX-command-list.
My .emacs contains
(setenv "PATH" (concat ".:/usr/texbin:/opt/local/bin" (getenv "PATH")))
(setq exec-path (append exec-path '(".:/usr/texbin:/opt/local/bin")))
(add-to-list 'load-path "/usr/local/share/emacs/site-lisp")
(require 'tex-site)
(load "auctex.el" nil t t)
(load "preview-latex.el" nil t t)
/usr/texbin is where latex/pdflatex/.. are located.
/opt/local/bin/ is where gs can be found.
And yet when I run preview-at-point, which apparently needs both latex and gs, I get
Preview-DviPS finished at Thu Dec 22 11:25:46
DviPS sentinel: Searching for program: No such file or directory, gs
which means that latex could be found all right, but not gs.
I am not sure whether setting exec-path is necessary, perhaps PATH is enough, but I've set it as a debugging measure.
Why can emacs not find gs even though the directory it's in is in both PATH and exec-path?
If you're setting $PATH inside your Emacs, you might well be on OS X. GUI applications are not started via your shell, so they see different environment variables.
Here's a trick which I use to ensure the $PATH inside Emacs is the same one I see if I fire up a terminal (but see "update" below):
(defun set-exec-path-from-shell-PATH ()
"Set up Emacs' `exec-path' and PATH environment variable to match that used by the user's shell.
This is particularly useful under Mac OSX, where GUI apps are not started from a shell."
(interactive)
(let ((path-from-shell (replace-regexp-in-string "[ \t\n]*$" "" (shell-command-to-string "$SHELL --login -i -c 'echo $PATH'"))))
(setenv "PATH" path-from-shell)
(setq exec-path (split-string path-from-shell path-separator))))
Then simply call the set-exec-path-from-shell-PATH function, perhaps from your Emacs init file. I keep that code on github, BTW.
Update: this code has now been improved and published as an elisp library called exec-path-from-shell; installable packages are available in MELPA.
Try replacing the second line with this:
(setq exec-path (append exec-path '("/usr/texbin" "/opt/local/bin")))
I hit a similar problem, but with a correct PATH, including trailing ´:´. It turned out the internal emacs shell program was missing, resulting in a ´Searching for program: No such file or directory´ message.
Fixed with
(setq shell-file-name "bash").
It appears you're missing a path separator : at the end of your path string.
