Link-protocols

[Christian Zang]

Dear all,

I use org-mode for notes, and DEVONthink and Papers on the mac for storing reference material. I want to add links to entries in DEVONthink and Papers to my org-files, but org doesn't understand links like

papers://doi/10.1038/463860a

or

x-devonthink-item://6EB3DF6A-9B0D-4D26-A7D3-86D0B589E455

However, when I paste these links into my browser, the desired documents open in the respective app. 

Is there a way to add these "protocols" to the protocols org can handle? I looked into org-follow-link, but couldn't come up with a solution.

Thanks!
Christian

Hi Christian,

Here is a snippet I use for opening Together links (another mac  
organizer):

--------------------------------------------------
(org-add-link-type "x-together-item" 'org-together-item-open)

(defun org-together-item-open (uid)
   "Open the given uid, which is a reference to an item in Together"
   (shell-command (concat "open \"x-together-item:" uid "\"")))
---------------------------------------------------

I suspect that this can be adapted for your purposes as well.

Regards,

Hi Anthony,

thanks for the snippet, it works perfectly with DEVONthink, but not with Papers.app. I suppose because the Papers-link contains slashes and might not be a proper uid...

Best,
Christian

Hi Anthony,

thanks a lot - that works! Indeed, the org-mailing-list is one of the nicest places on the 'web!

Best,
Christian

You could also try dragging the link from the app to the terminal and see what it pastes. Or if none of those work, you can try do some applescripting to try to figure it out.

If you send me the code you modified for papers.app and a small org file with a link in it, I'll take a look at it to see if there is something missing in the org setup. Also, which emacs and which org versions are you using?
