I've coded Org link support for EBDB, a contact management package, where the :complete key looks like:
(lambda () (format "ebdb:uuid/%s" (ebdb-record-uuid (ebdb-prompt-for-record (ebdb-records))))) Which prompts for a record based on the contact name, then inserts the contact's UUID as the link. The problem is that Org then prompts for a link description. I'd like to provide the contact name as a default description (the user has just typed it in, after all), but haven't figured out how to do that. Clearly `org-make-link-description-function' is meant to play this role, and it would work perfectly, but I don't know to set it. I can't set it globally, but also don't know how to let-bind it locally. How am I supposed to use it? Thanks, Eric
