How to customize **pylint-options** in Emacs - emacs

In pylint.el file, I found the definition:
(defcustom pylint-options '("--reports=n" "--output-format=parseable")
"Options to pass to pylint.py"
:type '(repeat string)
:group 'pylint)
I tried in my .emacs file:
(setq pylint-options "--some-option")
Then I got error when I try to run pylint in Emacs.

Command expects a list of strings, not just a string.
Like that:
(setq pylint-options '("--some-option"))

Emacs and CWB under Windows

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").

One-shot command to knit and latexmk under Emacs + AUCtex

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))))) ))

Emacs Auctex compile error: "Use M-x make-directory RET RET to create the directory and its parents"

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
(setq backup-by-copying t
backup-directory-alist '(("." . "~/.emacsBkups"))
delete-old-versions t
kept-new-versions 5
kept-old-versions 2
version-control t)

;;(ess-toggle-underscore nil)

(setq whitespace-style '(lines-tail face))

(setq TeX-view-program-list '(("Evince" "evince --page-index=%(outpage) %o")))
(setq TeX-view-program-selection '((output-pdf "Evince")))
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.

Add a TeX symbol in the Emacs init file

I am trying to add the following code to my .emacs init file:
(TeX-add-symbols '("eqref" TeX-arg-ref))
But I cannot get it to work. I get the following error when running emacs t.tex (t.tex is here a sample text file) from the command line:
Warning (initialization): An error occurred while loading `.emacs':
Symbol's function definition is void: TeX-add-symbols
I am using GNU Emacs version 23.3.1 on Ubuntu 12.04. My .emacs init file looks like
(setq TeX-auto-parse t)
(setq TeX-electric-escape t)
(setq reftex-label-alist '((nil ?e nil "~\\eqref{%s}" nil nil)))
(add-hook 'LaTeX-mode-hook 'turn-on-reftex)
(setq reftex-plug-into-AUCTeX t)
(TeX-add-symbols '("eqref" TeX-arg-ref))
If I enter ESC-: (i.e. running the command eval-expression) and enter
(TeX-add-symbols '("eqref" TeX-arg-ref)) at the prompt it works fine. (That is after running this, I can enter \eqref in the buffer and it works as expected.. But this is not a good solution, having to enter this code manually each time I edit a file.. That is the reason why I try to set it up in the .emacs file..)
Background information for this question:
I have a problem with using the AucTeX style amsmath.el.. it seems that it is not loaded properly on my machine.. For more information, see Using \eqref with RefTeX.
You have to evaluate the code after LaTeX-mode is activated, otherwise you get the error Symbol's function definition is void: TeX-add-symbols. You can add that function to the hook of LaTeX-mode. In order to override possible other eqref macro definitions, you should add a dummy (ignore) to the definition of the macro. This code, in your .emacs, does the trick:
(add-hook 'LaTeX-mode-hook
'(lambda ()
(TeX-add-symbols '("eqref" TeX-arg-ref (ignore)))))

Loading fic-mode in emacs

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?
