Subject: patch for custom colored links in org-mode
Date: Sun, 26 Jun 2016 09:35:59 -0400	[thread overview]
Message-ID: <m2d1n43we8.fsf@Johns-MacBook-Air.local> (raw)

Hi all,

I tried this aproach to enable custom colored links in org-mode if an
org-link-type face is defined. If no face is applied, then it just gets
the default org-link face

For example this will make all doi links red.

(defface org-link-doi
  `((t (:inherit org-link
                 :foreground "red")))
  "Color for doi links.")

It seems to work pretty well for me. What do you think about making this
a feature in org-mode?
