Thanks a lot, it gives me many ideas to explore.

[O] following org links to gnus messages and window management

2014-03-19 Thread Alan Schmitt
Hello,

I'm using escreen (http://www.emacswiki.org/emacs/EmacsScreen) to manage
my windows in emacs, typically keeping gnus on screen 0, org agenda and
related todo files on screen 2, and so on.

When I follow a link in a task to a gnus file, this takes over the
current frame, and when I'm done dealing with the message, I have to
winner-undo my way until I restore my window configuration. This is
not very convenient.

My questions are:
- is there a way to run some code before following a link (for instance
  save the current window configuration, or switch to screen 0)?
- if not, is there a way to copy a link then open it using the
  minibuffer (I would then do the switch to screen 0 manually)?
- finally, do you have alternative window management options to suggest
  that would work well with following links to gnus messages? I remember
  seeing something nice in Sacha Chua's interview of Magna Sveen
  mentioning perspective-mode, but I have not tried it yet.

Thanks,

Alan

Nope.

 - if not, is there a way to copy a link then open it using the
   minibuffer (I would then do the switch to screen 0 manually)?

This does not use the minibuffer but you could add that:

(progn
  (org-next-link)
  (org-open-link-from-string
   (org-element-property :raw-link (org-element-link-parser

 - finally, do you have alternative window management options to suggest

Well, all I can think of now is

(setq org-agenda-window-setup 'other-frame)

   I remember
   seeing something nice in Sacha Chua's interview of Magna Sveen
   mentioning perspective-mode, but I have not tried it yet.

Me neither!

Hope that helps,

   (org-open-link-from-string
(org-element-property :raw-link (org-element-link-parser

This was most helpful: I just need to copy the link I want to follow, go
to the first screen, and interactively call `org-open-link-from-string'.
This works great for the moment.

 Well, all I can think of now is

 (setq org-agenda-window-setup 'other-frame)

Thanks, but I'm trying to avoid using several frames. (OS
X unfortunately does not come with a window manager that I like ...)

Thanks again,

Alan

I have a setup that's probably more complicated than what you want, but
maybe you'll find something interesting in it. The problem is, you need
to somehow specify when or under what conditions you do away with the
opened windows and return to your org file or agenda. In my case, I use
the following to answer emails. When I open the link it stores the
current window configuration, and when the email is sent it triggers the
restore.

I believe I've confused myself slightly while trying to set up
interactive vs non-interactive versions, but so far I've never wanted to
use it non-interactively, so it works fine.
