4.6 Link abbreviations

Long URLs can be cumbersome to type, and often many similar links are needed in a document. For this you can use link abbreviations. An abbreviated link looks like this


where the tag is optional. The linkword must be a word, starting with a letter, followed by letters, numbers, ‘-’, and ‘_’. Abbreviations are resolved according to the information in the variable org-link-abbrev-alist that relates the linkwords to replacement text. Here is an example:

(setq org-link-abbrev-alist
  '(("bugzilla" . "")
    ("google"   . "http://www.google.com/search?q=")
    ("gmap"     . "http://maps.google.com/maps?q=%s")
    ("omap"     . "http://nominatim.openstreetmap.org/search?q=%s&polygon=1")
    ("ads"      . "http://adsabs.harvard.edu/cgi-bin/nph-abs_connect?author=%s")))

If the replacement text contains the string ‘%s’, it will be replaced with the tag. Otherwise the tag will be appended to the string in order to create the link. You may also specify a function that will be called with the tag as the only argument to create the link.

With the above setting, you could link to a specific bug with [[bugzilla:129]], search the web for ‘OrgMode’ with [[google:OrgMode]], show the map location of the Free Software Foundation [[gmap:51 Franklin Street, Boston]] or of Carsten office [[omap:Science Park 904, Amsterdam, The Netherlands]] and find out what the Org author is doing besides Emacs hacking with [[ads:Dominik,C]].

If you need special abbreviations just for a single Org buffer, you can define them in the file with

#+LINK: bugzilla
#+LINK: google    http://www.google.com/search?q=%s

In-buffer completion (see section 16.1 Completion) can be used after ‘[’ to complete link abbreviations. You may also define a function org-PREFIX-complete-link that implements special (e.g. completion) support for inserting such a link with C-c C-l. Such a function should not accept any arguments, and return the full link with prefix.
