using org-mode and screen

Hi everyone,
I use org-mode religiously these days.  I blogged about my use here (
http://technical-dresese.blogspot.com/2007/08/org-mode.html) (please excuse
the fact that when I wrote this I didn't know about the existing org-mode
functionality to jump to the current clock).

I generally have a problem of integrating the work I do in the shell with
the tasks in org-mode.   Plus, I often need access to the shells at home I
started from work.  I thought I'd combine these problems into a little
org-mode extension that ties screen and org-mode together, via ansi-term.

For these to work, you have to load ansi-term, which my hack is based on.

If there's enough interest, I'll make a real .el file out of this.

The general idea is that you start a task in which all the work will take
place in a shell.  This usually is not a leaf-task for me, but usually the
parent of a leaf task.  From a task in your org-file, M-x ash-org-screen
will prompt for the name of a session.  Give it a name, and it will insert a
link.  Open the link at any time to go the screen session containing your
work!

It works pretty well for me.  The only problem is that I often run emacs in
a screen session itself, and I can never get scrolling to work right in
screen-in-screen.

(defun ash-org-screen-buffer-name (name)

  "Returns the buffer name corresponding to the screen name given."

  (concat "*screen " name "*"))



(defun ash-org-screen-helper (name arg)

  ;; Pick the name of the new buffer.

  (let ((term-ansi-buffer-name (generate-new-buffer-name
(ash-org-screen-buffer-name name))))
    (setq term-ansi-buffer-name

          (term-ansi-make-term term-ansi-buffer-name "/usr/bin/screen" nil

                               arg name))



    (set-buffer term-ansi-buffer-name)

    (term-mode)

    (term-char-mode)



    (term-set-escape-char ?\C-x)

    term-ansi-buffer-name))



(defun ash-org-screen (name)

  "Start a screen session with name"

  (interactive "MScreen name: ")



  (save-excursion

    (ash-org-screen-helper name "-S"))

  (insert-string (concat "[[screen:" name "]]")))

And don't forget to add ("screen" . "elisp:(ash-org-goto-screen \"%s\")") to
org-link-abbrev-alist.
