Mac – Unicode in an Emacs regular expression

emacsregexunicode

I'm using emacs 24.

How can I replace all occurrences of the non-printable Unicode bidi character RTL, whose hexadecimal number is 202e? I want to replace it with the non-printable Unicode bidi character LTR, whose hexadecimal number is 202d?

Could someone give me some guidance?

This requires enable-recursive-minibuffers is set to non-nil:

M-x replace-regexp RET C-x 8 RET 202e RET RET C-x 8 RET 202d RET RET

Mac – Word count for LaTeX within emacs

(defun latex-word-count ()
  (interactive)
  (shell-command (concat "/usr/local/bin/texcount.pl "
                         ; "uncomment then options go here "
                         (buffer-file-name))))

You may opt to put texcount.pl somewhere other than /usr/local/bin, just modify the code as appropriate if you do. This creates a new command "M-x latex-word-count", which will run texcount.pl on the current file (it will give the wrong result if you have not saved the file though). You can remove the semicolon and replace the filler text with any command line arguments you want to use, if any. You can bind this to a keyboard command with something like this in your .emacs:

(define-key latex-mode-map "\C-cw" 'latex-word-count)

The page which describes how to install texcount is here: texcount faq. Short version:

sudo cp texcount.pl /usr/local/bin/texcount.pl

or alternatively you could do as they recommend and simply name it texcount, and update the code appropriately.

Mac – Running emacs inside screen

I only have input on your question #3.

As of emacs 23, emacs has a daemon mode which for me has obviated the need to run emacs inside screen. On my first login after a boot, I start emacs --daemon in a terminal. This starts emacs in the background. Then, whenever I need to use emacs, I either run emacsclient -nc to get an X window to my emacs session, or emacsclient -t to get a terminal session.

Multiple clients can coexist happily. I routinely run an X client on my workstation screen at work, an X client through ssh login from home, and a terminal client on my phone. All talking to the same emacs process, with all my buffers and other state intact. And should my ssh connection on my phone die, I can just continue where I left off after logging in again.

I don't know enough about keybindings in screen to help you with your first two questions.
