I have the following line in my emacs init file.
(setq auto-mode-alist (cons `("\*nrepl\*" . paredit-mode) auto-mode-alist))
I check that this works by creating a new buffer called *nrepl* Ctrl-x-f *nrepl*. Yes, the *nrepl* buffer has Paredit active, paredit-mode was enabled.
I close the *nrepl* buffer without saving it.
I start up a nrepl session by typing M-x nrepl-jack-in. The nrepl server starts up and I am presented with the nrepl repl. The nrepl repl is also called *nrepl*, however Paredit is not enabled.
What am I doing wrong?
You're confusing buffers and files: auto-mode-alist matches file names against regexps to decide which mode to use when editing those files. But *nrepl* is a buffer that does not contain a file, so auto-mode-alist has no effect for it.
Instead, you probably want to figure out which major-mode *nrepl* uses and then use (add-hook '<the-major-mode>-hook 'paredit-mode).
To put it simply - you need the following code:
(add-hook 'nrepl-mode-hook 'paredit-mode) ; for nrepl.el <= 0.1.8
(add-hook 'nrepl-repl-mode-hook 'paredit-mode) ; for nrepl.el > 0.1.8
Which is equivalent to the longer form:
(add-hook 'nrepl-mode-hook (lambda () (paredit-mode +1)))
(add-hook 'nrepl-mode-hook 'paredit-mode)
is what they suggest on the nrepl github page

I like to use terminal tools and the one of them is 'magit' - awesome Git client implemented as an Emacs package. I use it to control Git projects. I have a script which automatically start emacs at computer boot (this same me a time with routine work). But also I'm looking for a way to run emacs in magit-status mode (without manual executing M-x magit-status... each time). Emacs provide a possibility to configure it's environment in init configuration file. To make emacs run magit at boot I created special magit.el file and run emacs from command line
$ emacs -q --load ~/.emacs.d/magit.el
Unfortunately I unable to switch emacs in magic-status-mode - something wrong with init file. Emacs remains in lisp-interaction-mode after boot. The content of init file is below:
;; disable welcome screen at launch
(setq inhibit-startup-screen t)
(setq visible-bell t)
; Disable tabs indent
(setq-default c-basic-offset 4
tab-width 4
indent-tabs-mode nil)
(global-set-key "\C-h" 'delete-backward-char)
;; Makes *scratch* empty.
(setq initial-scratch-message "")
;; Removes *scratch* from buffer after the mode has been set.
(defun remove-scratch-buffer ()
(if (get-buffer "*scratch*")
(kill-buffer "*scratch*")))
;(add-hook 'after-change-major-mode-hook 'remove-scratch-buffer)
;; Removes *messages* from the buffer.
;(setq-default message-log-max nil)
;(kill-buffer "*Messages*")
;; Removes *Completions* from buffer after you've opened a file.
;(add-hook 'minibuffer-exit-hook
; '(lambda ()
; (let ((buffer "*Completions*"))
; (and (get-buffer buffer)
; (kill-buffer buffer)))))
;; Don't show *Buffer list* when opening multiple files at the same time.
(setq inhibit-startup-buffer-menu t)
;; Show only one active window when opening multiple files at the same time.
;(add-hook 'window-setup-hook 'delete-other-windows)
;; Tell emacs where is your personal elisp lib dir (magit)
(add-to-list 'load-path "~/.emacs.d/lisp/")
(load "git") ;; best not to include the ending “.el” or “.elc”
;; activate installed packages
(package-initialize)
(setq-default major-mode 'magit-status-mode)
(add-hook 'after-init-hook #'magit-status-mode)
(if after-init-time
(add-hook 'after-init-hook #'magit-status-mode))
Try this:
(call-interactively 'magit-status)
Instead of all of this:
(setq-default major-mode 'magit-status-mode)
(add-hook 'after-init-hook #'magit-status-mode)
(if after-init-time
(add-hook 'after-init-hook #'magit-status-mode))
Using after-init-hook would make sense in an init file, but with -q you're explicitly not using an init file (using --load is not the same thing), and that hook has already run by the time your custom magit.el file is loaded, so nothing you add to the hook at that stage will ever be processed.
Note that you don't want to call magit-status-mode at all. That's not a major mode you would ever be expected to invoke manually, as you would never want that mode for any buffer other than the one created by the magit-status command.
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)

; use the wx backend, for both mayavi and matplotlib
(setq py-python-command-args
'("--gui=wx" "--pylab=wx" "-colors" "Linux"))
;; responsible for the annoying window rearrangement behavior after every code execution? Nope.
(setq py-force-py-shell-name-p t)
; switch to the interpreter after executing code
(setq py-shell-switch-buffers-on-execute-p nil)
(setq py-switch-buffers-on-execute-p nil)

; try to automagically figure out indentation
(setq py-smart-indentation t)
; enable flycheck syntax support
; (add-hook 'after-init-hook #'global-flycheck-mode)
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 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.

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.
This answer gave me the solution I needed. The only problem for me, is that I have to load it, namely fic-mode, manually. More explicitly, whenever I open a c++ file, I have to do M-x fic-mode and then M-x font-lock-fontify-buffer in order to have it really up and running. In my .emacs I have
(require 'fic-mode)
(add-hook 'c++-mode-hook '(lambda () (fic-mode 1)))
but it doesn't do the trick.
Do you have any suggestions how to make it available automatically?
Try the following: create a new file containing the following three lines:
(setq load-path (cons "/path/to/fic-mode-directory" load-path))
(require 'fic-mode)
(add-hook 'c++-mode-hook 'turn-on-fic-mode)
Replace "/path/to/fic-mode-directory" with the absolute path to the directory in which you saved fic-mode.el.
Then from the command line, run
emacs -Q -l /path/to/file
where /path/to/file is the path to the above file.
Now type C-x C-f test.cpp.
Is fic-mode turned on in the resulting buffer?
