transitioning links defined in packages from pre org-9 to org-9

transitioning links defined in packages from pre org-9 to org-9

[John Kitchin]

Hi,

I am working through a transition from org8 to org9, and trying to
figure out how to update packages that define links in way that doesn't
break people not ready to update org. For example, in mu4e there is an
mu4e link defined that needs to be updated so I can store links in
emails. Also, org-ref will get an overhaul on links, but a lot of my
students will still be on org-8.

Is something like this robust? Any other suggestions? 


(if (string-prefix-p "9" (org-release))
    (org-link-set-parameters
     "mu4e"
     :follow 'org-mu4e-open
     :store 'org-mu4e-store-link)
  ;; org versions less than 9
  (org-add-link-type "mu4e" 'org-mu4e-open)
  (add-hook 'org-store-link-functions 'org-mu4e-store-link))


Would it make sense to have some macros to facilitate this? e.g.
something like

(org-9
  (org-link-set-parameters
     "mu4e"
     :follow 'org-mu4e-open
     :store 'org-mu4e-store-link))

(org-8
  (org-add-link-type "mu4e" 'org-mu4e-open)
  (add-hook 'org-store-link-functions 'org-mu4e-store-link))
