Using minted (source code LaTeX package) with emacs/auctex

Question

As is explained in here, I find minted package is pretty cool for source code listing.

My question is how to use minted package with AucTeX/emacs? For command line I can use pdflatex -shell-escape SOURCE, but

• Q1 : How can I modify the AucTeX to insert the -shell-escape? I mean, how to change the action for C-c+C-c?
• Q2 : Do I need special key other than C-c+C-c for -shell-escape option? Or, is it just OK to use it without any problem?
• Q3 : What is the -shell-escape for?

Answer 1

Q1: You need to edit the way LaTeX is called by AucTeX. One way of doing this is to add the following to your .emacs file:

(eval-after-load "tex" 
  '(setcdr (assoc "LaTeX" TeX-command-list)
          '("%`%l%(mode) -shell-escape%' %t"
          TeX-run-TeX nil (latex-mode doctex-mode) :help "Run LaTeX")
    )
  )

Q2: Once you have made the changes, all calls to LaTeX with C-c C-c will use the -shell-escape option.

Q3: See Konrad's answer. Note that this method will enable -shell-escape for all files edited in AucTeX, so can be a potential security risk if using other peoples packages or files.

I can only answer question 3:

What is the '-shell-escape' for?

minted uses a third-party application, pygmentize, to process the source code. LaTeX usually doesn’t allow calling other applications for security reasons (a rogue package could otherwise call aribtrary code). To explicitly enable calling external applications, you need to enable this so-called escape to the shell – which, on most LaTeX installations, is done via the -shell-escape switch.

Answer 3

In recent versions of auctex, it looks like it'll be more reliable to set TeX-command-extra-options, which is designed for just this purpose, and doesn't make you override the various forms of TeX-command. As I understand it (might be wrong), this can't be set globally, but must be set for each file. You can do this with a hook. For example, in .emacs you might add this:

(add-hook 'TeX-mode-hook
  (lambda ()
    (setq TeX-command-extra-options "-shell-escape")
  )
)

And since you don't fully overwrite the latex command call, other features will still work -- like turning on synctex support with (setq TeX-source-correlate-mode t) [which can happen outside the hook].
