Control emacs from your mobile

This week I participated at the emacs FFM Meetup where we talked about the idea of a chat bot extension for org-mode. I had to leave early, so I do not know what the results of the discussion were.

Nevertheless I did some thought on my own:

I would like to control everything I do in emacs from my mobile while I'm on-the-go - not only org-mode related things.

On the emacs side one could utilise org-protocol which can be extended with additional protocol-handlers and despite the name it can also be used for things beside org-mode.

The protocol could be fairly simple and the command could be reduced to: mode which is the sub-protocol, action and data.

Some examples (not url-encoded for better readability):

org-protocol://sub-protocol?key=val&key2=val2
org-protocol://ledger?action=add&data=value:5,00€;account1:cash;account2:snacks;payee:Not Starbucks;comments:fine coffee
org-protocol://cal?action=list&data=from:today;for:1week

Any results could be written to a special file which would be used to inform the user¹.

The middleware-component which is here called emacs-engine could be e.g.

• a chat bot

• a gRPC client

• a REST client

So it would be possible to integrate emacs-engine into workflows implemented by Apple Shortcuts.
