Out of the box, :ls in evil-mode invokes M-x list-buffers. What do I need to put into my .emacs to rebind this to run M-x ibufferinstead?
Changing this has nothing to do with evil-mode: (defalias 'list-buffers 'ibuffer)
Specifying (defalias 'list-buffers 'ibuffer) didn't work for me.
In looking at source file 'evil-maps.el' I found another method.
Add to your .emacs file:
;; bind ':ls' command to 'ibuffer instead of 'list-buffers
(evil-ex-define-cmd "ls" 'ibuffer)
This method should be able to map any evil ex command.

I'm trying to enable whitespace mode but it doesn't seem to be working for me.
I've added the whitespace.el file to my .emacs.d/ directory.
I added the following lines to me .emacs file:
(add-hook 'before-save-hook 'whitespace-cleanup)
(add-hook 'before-save-hook (lambda() (delete-trailing-whitespace)))
(require 'whitespace)
I did the following in the whitespace.el file:
M-x byte-compile-file <path to whitespace.el>
I tried executing the following command from any random text in emacs (e.g.: test.c):
M-x whitespace-toggle-options RET
But I just get a message saying [No match]
What am I missing?
Also, will I have to type in a command to enable the whitespace-mode every time I use emacs?
whitespace.el has been included in Emacs for quite a while. Unless you have a very old version, you shouldn't need to manually put it anywhere, or do anything particularly special to use it.
whitespace-toggle-options probably isn't the function you want to use. Instead, try whitespace-mode:
Toggle whitespace visualization (Whitespace mode).
With a prefix argument ARG, enable Whitespace mode if ARG is
positive, and disable it otherwise. If called from Lisp, enable
the mode if ARG is omitted or nil.
If you want to enable it by default, add
(global-whitespace-mode)
to your init file.
I am a new to ocaml. couldn't install rlwrap since I use a school computer.
So I have to stick to emacs tuareg.
My question is:
How to bind an up arrow key to the previous command in tuareg?
Just use M+p instead of the arraw key :)
But you can also add the following lines to your .emacs file:
(add-hook 'tuareg-interactive-mode-hook
(lambda ()
(local-set-key (kbd "<up>") 'comint-previous-input)
)
)
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'm working with GNU Emacs 23.3 (9.0) on Mac OS X 10.7.2. I would like to use synctex to jump between .tex and .pdf files. Although there are many different approaches on the web, none worked properly (I tried 8 different approaches...). I finally ended up with the rather simple approach described here: http://sourceforge.net/apps/mediawiki/skim-app/index.php?title=TeX_and_PDF_Synchronization
So my .emacs contains:
'(LaTeX-command "latex -synctex=1")
(require 'tex-site)
(add-hook 'TeX-mode-hook
(lambda ()
(add-to-list 'TeX-output-view-style
'("^pdf$" "."
"/Applications/Skim.app/Contents/SharedSupport/displayline -b %n %o %b")))
)
(server-start)
Of course, I also set up Skim (Preferences -> Sync -> checked "Check for file changes" and chose Preset: Emacs with command emacsclient and arguments --no-wait +%line "%file")
As you can see, I included the -b option to displayline. I can call displayline from the terminal and it opens the .pdf and displays the corresponding line with a yellow/highlighted bar. Still, nothing is displayed on the current line if I compile the document with latexmk -pvc -pdf from a shell within Emacs.app.
Question 1: How can I get this to work/How can I display the current line?
Question 2: Is it possible to have a "proper" forward search by clicking the .tex and jumping to the corresponding line in the .pdf document? How can I "click" in emacs? The standard CMD + shift + click does not work in emacs.
I also tried approaches using...
(setq TeX-source-correlate-method 'synctex)
(add-hook 'LaTeX-mode-hook 'TeX-source-correlate-mode)
... but nothing changes.
I can CMD + shift + click in the .pdf and jump to the .tex, so that works.
The only directions which I haven't looked into are:
is this a latexmk problem? Most likely not, since latexmk explicitly displays pdflatex -interaction=nonstopmode -synctex=1 so synctex is recognized
is it a wrong skim preference setting? Maybe I have to adjust the arguments to emacsclient there (?)
Solution
Indeed latexmk is the problem. I finally figured out the following settings:
~/.emacs
;; make latexmk available via C-c C-c
;; Note: SyncTeX is setup via ~/.latexmkrc (see below)
(add-hook 'LaTeX-mode-hook (lambda ()
(push
'("latexmk" "latexmk -pdf %s" TeX-run-TeX nil t
:help "Run latexmk on file")
TeX-command-list)))
(add-hook 'TeX-mode-hook '(lambda () (setq TeX-command-default "latexmk")))
;; use Skim as default pdf viewer
;; Skim's displayline is used for forward search (from .tex to .pdf)
;; option -b highlights the current line; option -g opens Skim in the background
(setq TeX-view-program-selection '((output-pdf "PDF Viewer")))
(setq TeX-view-program-list
'(("PDF Viewer" "/Applications/Skim.app/Contents/SharedSupport/displayline -b -g %n %o %b")))
(server-start); start emacs in server mode so that skim can talk to it
~/.latexmkrc
$pdflatex = 'pdflatex -interaction=nonstopmode -synctex=1 %O %S';
$pdf_previewer = 'open -a skim';
$clean_ext = 'bbl rel %R-blx.bib %R.synctex.gz';
This perfectly allows to compile with latexmk as default on C-c C-c and C-c C-v opens Skim at the current line which is nicely highlighted. With CMD + shift + click in the .pdf, one can then jump back to the corresponding paragraph in the .tex file (thanks to server-start).
To enable the clicking feature of the sync, I added:
(add-hook 'LaTeX-mode-hook
(lambda () (local-set-key (kbd "<S-s-mouse-1>") #'TeX-view))
)
to my .emacs file.
NOTE: make sure that you are in PDF mode (use (setq TeX-PDF-mode t)).
When you press C-c C-v (which runs TeX-view) it should open Skim with the bar on the current line. This is what you set up with the TeX-output-view-style. You can't get that behaviour from latexmk -pvc since it doesn't know which line you are on. All latexmk knows is that the file changed. In order to do a forward search you need to run TeX-view.
You can bind CMD + shift + click to run TeX-view by adding
(define-key LaTeX-mode-map [M-S-mouse-1] 'TeX-view)
or possibly
(define-key LaTeX-mode-map [s-S-mouse-1] 'TeX-view)
to your TeX-mode-hook. It depends on your settings which you need, but can find out by pressing C-h C-k and then CMD+shift+click. Of course adding both shouldn't cause a problem.
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?
