Hi,
I am running emacs-mac-app (v. 25.3.1) installed from Mac Ports, with org-mode version 9.1.6, on Mac OS 10.13.3.
I have set up org-protocol. If I open a terminal emulator window and enter this command
emacsclient -n "org-protocol:/capture?url="">
org-protocol works. I can select the template I want, and an entry gets added to my .org file.
However, if I add in a template specification
emacsclient -n "org-protocol:/capture?template=t?url="">
I get this error:
*ERROR*: No capture template referred to by "t?url" keys
It seems the list isn't getting split at the '?' after 'template=t'. I haven't been able to find anything on this and appear to be doing what org-protocol.el says I should.
